From the npm docs, only visible prepared statements are for insert. Does these prepared statement work for Select, update, and delete?
I tried for select, there isn't a .each function where the rows are called back. Anyone been able to do this or have links to resources, cause I can sure as hell unable to find any.
According to the node-sqlite3 API documentation, you can use parameters in your SQL queries in several different ways:
// Directly in the function arguments.
db.run("UPDATE tbl SET name = ? WHERE id = ?", "bar", 2);
// As an array.
db.run("UPDATE tbl SET name = ? WHERE id = ?", [ "bar", 2 ]);
// As an object with named parameters.
db.run("UPDATE tbl SET name = $name WHERE id = $id", {
$id: 2,
$name: "bar"
});
Yes, prepared statements are supported.
With node-sqlite3:
var sqlite3 = require('sqlite3').verbose();
var db = new sqlite3.Database('data.db');
db.serialize(function() {
var stmt = db.prepare("INSERT INTO users VALUES (?,?)");
for (var i = 0; i < 10; i++) {
stmt.run("user " + i, "email " + i);
}
stmt.finalize();
stmt = db.prepare("SELECT * FROM users WHERE id=?");
stmt.each(userId, function(err, row) {
console.log(row.name, row.email);
}, function(err, count) {
stmt.finalize();
});
});
With better-sqlite3:
var Database = require('better-sqlite3');
var db = new Database('foobar.db', options);
var stmt = db.prepare("INSERT INTO users VALUES (?,?)");
for (var i = 0; i < 10; i++) {
stmt.run("user " + i, "email " + i);
}
var stmt = db.prepare('SELECT * FROM users WHERE id=?');
var row = stmt.get(userId);
console.log(row.name, row.email);

In google docs one can easily add headings and link to them from inside of the document. But when the heading text changes, the link text does not change.
Is there a way to change that behavior or update the link text automatically?
I know it is about 1 1/2 years, but maybe this will help. I have had the exact same problem and wrote a function that will update all the links to the headings in a document. Since I could not find any built-in functions or add-ons, the only way was to script it.
Some things to consider:
This needs a current table of contents to work. If you don't have (or do not want) a TOC, you can insert one, run that function and delete it afterwards. Also, I have only tested it with a TOC that contains page numbers.
It will update ALL texts of links to headings in the document. However, links to everything else remain untouched.
Please use at your own risk (maybe try it out in a copy of your document). I have tested it, but the testing could have been more thorough. Also, this is my first in scripting Docs.
Paste this in the Script editor of your doc and run replaceHeadingLinks. Links that the script could not update (because they link to a heading that does not exist anymore) will be output in the console.
function replaceHeadingLinks() {
var curDoc = DocumentApp.getActiveDocument();
var links = getAllLinks_(curDoc.getBody());
var headings = getAllHeadings_(curDoc.getBody());
var deprecatedLinks = []; // holds all links to headings that do not exist anymore.
links.forEach(function(link) {
if(link.url.startsWith('#heading')) {
// get the new heading text
var newHeadingText = headings.get(link.url);
// if the link does not exist anymore, we cannot update it.
if(typeof newHeadingText !== "undefined") {
var newOffset = link.startOffset + newHeadingText.length - 1;
// delete the old text, insert new one and set link
link.element.deleteText(link.startOffset, link.endOffsetInclusive);
link.element.insertText(link.startOffset, newHeadingText);
link.element.setLinkUrl(link.startOffset, newOffset, link.url);
} else {
deprecatedLinks.push(link);
}
}
}
)
// error handling: show deprecated links:
if(deprecatedLinks.length > 0) {
Logger.log("Links we could not update:");
for(var i = 0; i < deprecatedLinks.length; i++) {
var link = deprecatedLinks[i];
var oldText = link.element.getText().substring(link.startOffset, link.endOffsetInclusive);
Logger.log("heading: " + link.url + " / description: " + oldText);
}
} else {
Logger.log("all links updated");
}

I'm trying to generate a content tree for a simple wiki. Each page has a Children property that stores the id of other wiki pages. I'm trying to write a SPROC that gets all of the documents, then iterate over each page's Children property and replace each item with an actual wiki page document. I'm able to get the first set of documents, but the wikiChildQuery returns undefined and I'm not quite sure why.
I've been able to get a document with the query alone but for some reason, it doesn't work within the SPROC. Is there something I'm missing here?
function GetWikiMetadata(prefix) {
var context = getContext();
var collection = context.getCollection();
var metadataQuery = 'SELECT {\"ExternalId\": p.ExternalId, \"Title\": p.Title, \"Slug\": p.Slug, \"Children\": p.Children} FROM Pages p'
var metadata = collection.queryDocuments(collection.getSelfLink(), metadataQuery, {}, function (err, documents, options) {
if (err) throw new Error('Error: ', + err.message);
if (!documents || !documents.length) {
throw new Error('Unable to find any documents');
} else {
var response = getContext().getResponse();
for (var i = 0; i < documents.length; i++) {
var children = documents[i]['$1'].Children;
if (children.length) {
for (var j = 0; j < children.length; j++) {
var child = children[j];
children[j] = GetWikiChildren(child);
}
}
}
response.setBody(documents);
}
});
if (!metadata) throw new Error('Unable to get metadata from the server');
function GetWikiChildren(child) {
var wikiChildQuery = metadataQuery + ' WHERE p.ExternalId = \"' + child + '\"';
var wikiChild = collection.queryDocuments(collection.getSelfLink(), wikiChildQuery, {}, function(err, document, options) {
if (err) throw new Error('Error: ', + err.message);
if (!document) {
throw new Error('Unable to find child Wiki');
} else {
var children = document.Children;
if (children) {
for (var k = 0; k < children.length; k++) {
var child = children[k];
children[k] = GetWikiChildren(child);
}
} else {
return document;
}
}
if (!wikChild) throw new Error('Unable to get child Wiki details');
});
}
}
1.I'm able to get the first set of documents, but the wikiChildQuery
returns undefined and I'm not quite sure why.
Firstly, here should be corrected. In the first loop, you get children array with documents[i]['$1'].Children, however , in the GetWikiChildren function you want to get children array with document.Children? Surely,it is undefined. You need to use var children = document[0]['$1'].Children;
2.It seems that you missed the replaceDocument method.
You could refer to the snippet code of your metaDataQuery function:
for (var i = 0; i < documents.length; i++) {
var children = documents[i]['$1'].Children;
if (children.length) {
for (var j = 0; j < children.length; j++) {
var child = children[j];
children[j] = GetWikiChildren(child);
}
}
documents[i]['$1'].Children = children;
collection.replaceDocument(doc._self,doc,function(err) {
if (err) throw err;
});
}
3.Partial update is not supported by Cosmos db SQL Api so far but it is hitting the road.
So, if your sql doesn't cover your whole columns,it can't be done for your replace purpose.(feedback) It is important to note that the columns which is not mentioned in the replace object would be devoured while using replaceDocument method.
Below is code I came up with to run a Saved Search in NetSuite using SuiteScript, create a CSV with the Saved Search results and then email the CSV. The trouble is, the results are limited to 1000 records. I've researched this issue and it appears the solution is to run a loop that slices in increments of 1000. A sample of what I believe is used to slice searches is also below.
However, I cannot seem to be able to incorporate the slicing into my code. Can anyone help me combine the slicing code with my original search code?
var search = nlapiSearchRecord('item', 'customsearch219729');
// Creating some array's that will be populated from the saved search results
var content = new Array();
var cells = new Array();
var temp = new Array();
var x = 0;
// Looping through the search Results
for (var i = 0; i < search.length; i++) {
var resultSet = search[i];
// Returns an array of column internal Ids
var columns = resultSet.getAllColumns();
// Looping through each column and assign it to the temp array
for (var y = 0; y <= columns.length; y++) {
temp[y] = resultSet.getValue(columns[y]);
}
// Taking the content of the temp array and assigning it to the Content Array.
content[x] += temp;
// Incrementing the index of the content array
x++;
}
//Inserting headers
content.splice(0, 0, "sku,qty,");
// Creating a string variable that will be used as the CSV Content
var contents;
// Looping through the content array and assigning it to the contents string variable.
for (var z = 0; z < content.length; z++) {
contents += content[z].replace('undefined', '') + '\n';
}
// Creating a csv file and passing the contents string variable.
var file = nlapiCreateFile('InventoryUpdate.csv', 'CSV', contents.replace('undefined', ''));
// Emailing the script.
function SendSSEmail()
{
nlapiSendEmail(768, 5, 'Inventory Update', 'Sending saved search via scheduled script', 'cc#email.com', null, null, file, true, null, 'cc#email.com');
}
The following code is an example of what I found that is used to return more than a 1000 records. Again, as a novice, I can't seem to incorporate the slicing into my original, functioning SuiteScript. Any help is of course greatly appreciated.
var filters = [...];
var columns = [...];
var results = [];
var savedsearch = nlapiCreateSearch( 'customrecord_mybigfatlist', filters, columns );
var resultset = savedsearch.runSearch();
var searchid = 0;
do {
var resultslice = resultset.getResults( searchid, searchid+1000 );
for (var rs in resultslice) {
results.push( resultslice[rs] );
searchid++;
}
} while (resultslice.length >= 1000);
return results;
Try out this one :
function returnCSVFile(){
function escapeCSV(val){
if(!val) return '';
if(!(/[",\s]/).test(val)) return val;
val = val.replace(/"/g, '""');
return '"'+ val + '"';
}
function makeHeader(firstLine){
var cols = firstLine.getAllColumns();
var hdr = [];
cols.forEach(function(c){
var lbl = c.getLabel(); // column must have a custom label to be included.
if(lbl){
hdr.push(escapeCSV(lbl));
}
});
return hdr.join(",");
}
function makeLine(srchRow){
var cols = srchRow.getAllColumns();
var line = [];
cols.forEach(function(c){
if(c.getLabel()){
line.push(escapeCSV(srchRow.getText(c) || srchRow.getValue(c)));
}
});
return line.join(",");
}
function getDLFileName(prefix){
function pad(v){ if(v >= 10) return v; return "0"+v;}
var now = new Date();
return prefix + '-'+ now.getFullYear() + pad(now.getMonth()+1)+ pad(now.getDate()) + pad( now.getHours()) +pad(now.getMinutes()) + ".csv";
}
var srchRows = getItems('item', 'customsearch219729'); //function that returns your saved search results
if(!srchRows) throw nlapiCreateError("SRCH_RESULT", "No results from search");
var fileLines = [makeHeader(srchRows[0])];
srchRows.forEach(function(soLine){
fileLines.push(makeLine(soLine));
});
var file = nlapiCreateFile('InventoryUpdate.csv', 'CSV', fileLines.join('\r\n'));
nlapiSendEmail(768, 5, 'Test csv Mail','csv', null, null, null, file);
}
function getItems(recordType, searchId) {
var savedSearch = nlapiLoadSearch(recordType, searchId);
var resultset = savedSearch.runSearch();
var returnSearchResults = [];
var searchid = 0;
do {
var resultslice = resultset.getResults(searchid, searchid + 1000);
for ( var rs in resultslice) {
returnSearchResults.push(resultslice[rs]);
searchid++;
}
} while (resultslice.length >= 1000);
return returnSearchResults;
}
I looked into your code but it seems you're missing the label headers in the generated CSV file. If you are bound to use your existing code then just replace
var search = nlapiSearchRecord('item', 'customsearch219729');
with
var search = getItems('item', 'customsearch219729');
and just use the mentioned helper function to get rid off the 1000 result limit.
Cheers!
I appreciate it has been a while since this was posted and replied to but for others looking for a more generic response to the original question the following code should suffice:
var search = nlapiLoadSearch('record_type', 'savedsearch_id');
var searchresults = search.runSearch();
var resultIndex = 0;
var resultStep = 1000;
var resultSet;
do {
resultSet = searchresults.getResults(resultIndex, resultIndex + resultStep); // retrieves all possible results up to the 1000 max returned
resultIndex = resultIndex + resultStep; // increment the starting point for the next batch of records
for(var i = 0; !!resultSet && i < resultSet.length; i++){ // loop through the search results
// Your code goes here to work on a the current resultSet (upto 1000 records per pass)
}
} while (resultSet.length > 0)
Also worth mentioning, if your code is going to be updating fields / records / creating records you need to bear in mind script governance.
Moving your code to a scheduled script to process large volumes of records is more efficient and allows you to handle governance.
The following line:
var savedsearch = nlapiCreateSearch( 'customrecord_mybigfatlist', filters, columns );
can be adapted to your own saved search like this:
var savedsearch = nlapiLoadSearch('item', 'customsearch219729');
Hope this helps.
Suppose I have 2 Lists: Teams and Employees. Each team has a number of employees:
Teams
ID
Name
Employees
ID
Name
TeamID (foreign key of Teams)
Is it possible to write a query in SharePoint JSOM such that I could do something along the following lines (after the query executes/loads):
var employeesListItems = teamListItem.get_item("Employees")
Does SharePoint Object Model support this in any way?
Clarification: my intent is to reuse the ClientObject as much as I can. I understand that I could query for all employees and all teams, create an array of custom objects for each, and then iterate over employees and push them to onto the "Employees" field of the related Team object. I would like to avoid doing so.
Even though SharePoint CAML supports List Joins and Projections, in that case I would suggest you a different approach.
The following example demonstrates how to retrieve parent/child items using a single request:
function getItemWithDetails(parentListTitle,childListTitle,lookupFieldName,lookupFieldValue,success,error)
{
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var lists = web.get_lists();
var parentList = lists.getByTitle(parentListTitle);
var parentItem = parentList.getItemById(lookupFieldValue);
var childList = lists.getByTitle(childListTitle);
var childItems = childList.getItems(createLookupQuery(lookupFieldName,lookupFieldValue));
ctx.load(parentItem);
ctx.load(childItems);
ctx.executeQueryAsync(
function() {
success(parentItem,childItems);
},
error
);
}
function createLookupQuery(lookFieldName,lookupFieldValue)
{
var queryText =
"<View>" +
"<Query>" +
"<Where>" +
"<Eq>" +
"<FieldRef Name='{0}' LookupId='TRUE'/>" +
"<Value Type='Lookup'>{1}</Value>" +
"</Eq>" +
"</Where>" +
"</Query>" +
"</View>";
var qry = new SP.CamlQuery();
qry.set_viewXml(String.format(queryText,lookFieldName,lookupFieldValue));
return qry;
}
Usage
var parentListTitle = 'Teams';
var childListTitle = 'Employees'
var lookupFieldValue = 1;
var lookupFieldName = 'Team';
getItemWithDetails(parentListTitle,childListTitle,lookupFieldName,lookupFieldValue,
function(teamItem,employeeItems){
//print parent item
console.log(teamItem.get_item('Title'));
//print child items
for(var i = 0; i < employeeItems.get_count(); i++){
var employeeItem = employeeItems.getItemAtIndex(i);
console.log(employeeItem.get_item('Title'));
}
},
function(sender,args){
console.log(args.get_message());
});
Another option is to utilize List Joins and Projections. The following example demonstrates how to retrieve employee list items with projected team items
function getListItems(listTitle,joinListTitle,joinFieldName,projectedFields,success,error)
{
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var list = web.get_lists().getByTitle(listTitle);
var items = list.getItems(createJoinQuery(joinListTitle,joinFieldName,projectedFields));
ctx.load(items);
ctx.executeQueryAsync(
function() {
success(items);
},
error
);
}
function createJoinQuery(joinListTitle,joinFieldName,projectedFields)
{
var queryText =
"<View>" +
"<Query/>" +
"<ProjectedFields>";
for(var idx in projectedFields) {
queryText += String.format("<Field Name='{0}_{1}' Type='Lookup' List='{0}' ShowField='{1}' />",joinListTitle,projectedFields[idx]);
}
queryText +=
"</ProjectedFields>" +
"<Joins>" +
"<Join Type='INNER' ListAlias='{0}'>" +
"<Eq>" +
"<FieldRef Name='{1}' RefType='Id'/>" +
"<FieldRef List='{0}' Name='ID'/>" +
"</Eq>" +
"</Join>" +
"</Joins>" +
"</View>";
var qry = new SP.CamlQuery();
qry.set_viewXml(String.format(queryText,joinListTitle,joinFieldName));
return qry;
}
Usage
var listTitle = 'Employees';
var joinListTitle = 'Teams'
var joinFieldName = 'Team';
var projectedFields = ['ID','Title'];
getListItems(listTitle,joinListTitle,joinFieldName,projectedFields,
function(employeeItems){
//print items
for(var i = 0; i < employeeItems.get_count(); i++){
var employeeItem = employeeItems.getItemAtIndex(i);
var employeeName = employeeItem.get_item('Title');
var teamName = employeeItem.get_item('Teams_Title').get_lookupValue();
console.log(employeeName + ',' + teamName);
}
},
function(sender,args){
console.log(args.get_message());
});
Probably you can not achieve what you want, because of lookup configuration. But you could do the following:
var ctx = SP.ClientContext.get_current();
var web = ctx.get_web();
var lists = web.get_lists();
var teams = lists.getByTitle("Teams");
var employees = lists.getByTitle("Employees");
//just get the first item
var employee = employees.getItemById(1);
ctx.load(employee)
ctx.executeQueryAsync(function() {
var team = employee.get_item("TeamID");
// both the id and the value of the lookup field
var lookupId = team.get_lookupId();
var lookupValue = team.get_lookupValue();
// let's grab all the fields
var fullTeam = teams.getItemById(lookupId)
ctx.load(fullTeam)
ctx.executeQueryAsync({
var name = fullTeam.get_item("Name");
alert("We can get the Name field of the lookup field: " + name);
});
});
I guess, it a bit reverse of what you really intent to achieve but still this way you will exploit CSOM.
I am not able to get the list of item.I am using a saved search and want to create a list of all the item record id from it.
But it is not working.
my code
var loadSearch=nlapiLoadSearch('item','customsearch12');
var getData = loadSearch.runSearch();
var itemCol=new Array();
for(var i=0;i<getData.length;i++)
{
itemCol.push(getData[i].getId());
}
Can somebody help me with this
try this code
var loadSearch=nlapiLoadSearch('item','customsearch12');
var getData = loadSearch.runSearch();
var itemCol=new Array();
getData.forEachResult(function (searchRow) {
itemCol.push(searchRow.getId());
return true;
});
when you use a nlapiLoadSearch, the result is nlobjSearchResultSet and not an array like in the case of nlapiSearchRecord.
if you use nlapiSearchRecord, then you can loop through the result like you were trying in your code, i.e. using index
The answer given above by Nitish is perfectly correct but you need to consider one more thing.
nlapiLoadSearch api returns 4000 records at a time.
The nlapiSearchRecord api returns only 1000 records at a time , so what if your saved search consists of more than 1000 records.
So you will miss those extra items.
so here is the code to have better results
//Searching the items
var searchResults = nlapiSearchRecord('item', 'customsearch12',null,null);
var searchedItemId;
var lastId;
var completeResults = new Array();
var arrNewFilters=[];
if (searchResults != null) {
completeResults = completeResults.concat(searchResults);
}
else {
completeResults = null;
nlapiLogExecution('Debug', 'No item found',
weight + ' Null result');
}
if (completeResults != null) {
if (searchResults.length == 1000) {
while (searchResults.length == 1000) {
//Initialize variable
lastId = "";
//Get Record Id of Last record,
//to search the item record again from that record
lastId = searchResults[999].getId();
//start after the last id searched
arrNewFilters.push(new nlobjSearchFilter("internalidnumber",
null, "greaterthan", lastId));
//Lets search again
var searchResults = nlapiSearchRecord('item', 'customsearch12',
arrNewFilters, null);
if (searchResults != null) {
//Append the search result to the result present before
completeResults = completeResults.concat(searchResults);
}
}
}
for (var result = 0; result < completeResults.length; result++) {
//Loop through the items
}
Hope you got me Nitish!!!
Here's a sample of how to fetch over 1k of results in NetSuite/NetScript.
The search "customsearch_tel_tg_by_trunk_type" is not really relevant.
Complete sample of 1k+ results fetch in NetSuite/NetScript
You could get all the results one by one using a callback function till all the records are iterated.
var search = nlapiLoadSearch('item','customsearch12');
var resultSet = loadSearch.runSearch();
var itemCol=new Array();
resultSet.forEachResult(function (iterator) {
itemCol.push(iterator.getId());
return true;
});
or you could load few records of it using the getResults of the nlobjResultSet
var search = nlapiLoadSearch('item', 'customsearch12');
var resultSet = search.runSearch();
var results = resultSet.getResults(0, 100);//get the results from 0 to 100 search results
var itemCol = new Array();
for(var i in results)
{
itemCol.push(results[i].getValue('id'));
}
