I recently started playing around with SubSonic 2.2 (only 2.2 because I didn't find any Oracle t4 templates at the time). That aside, I have been noticing that I can run a query on table a and field b will have a value of 1. If I went into Sql Tools or Oracle Developer and changed field b to a value of 2, SubSonic's LoadByKey functions still returns an object with field b having a value of 1.
In case that is hard to read.
var id = "primary key";
x.LoadByKey(id);
Console.Write(x.b); -> yields 1
I can go change this value in another program and rerun the code and it is always 1 regardless.
Any ideas?
The only thing I can think is that it's an app issue, or a driver-level issue. We don't implement any kind of caching.

There are N tables in the DB with the following data types:
Numeric, long text, date and time bigint, boolean.
All of them opens, except one
I'm opening a database
db = QSqlDatabase("QODBC")
db.setDatabaseName(r"DRIVER={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=C:\Users\...\file.accdb")
db.open(username, password)
I output the tables contained in the db
db.tables()
Output:
["messages", "table1", "table2", ..., "tableN"]
And I'm trying to open the "messages" table
model = QSqlTableModel(db=db)
model.setTable("messages")
model.select()
Output:
False
Then I checked which other tables are not opening
for i in db.tables():
model.setTable(i)
if model.select() == False:
print(i)
Output:
"messages"
This means that the problem is only in this table.
But directly through MS Access the table opens
I have already tried to open it through the cycle. The keyword was found in db.tables(), but QSqlTableModel does not see the 'messages' table specifically.
I tried to change MS Access to the 2016 version. I thought, suddenly some certain type from MS Access 2019 conflicts with the old driver. It didn't help.
I was thinking of downloading a newer driver, but I didn't find one. I tried to dig into the registry... I didn't find anything either.
Please help
So, I figured out the problem by poking. I was initially right about the driver conflict with the bigint data type, but a few additional actions were missing.
Apparently, when you try to set the bigint data type and save it, Access warns you that because of it, databases may not support older versions, and you save anyway, it automatically sets the minimum supported version, or what?
Data separation helped, but before that you need to change the bigint data type to another data type. Database Tools->Move Data->Access Database.
This question may seem rudimentary but nothing that I have found online quite fits.
I am looking at an old FOXPRO script that we used to make a table. At the moment, I am attempting to translate this script into SQL. Of note is the following,
delete all for code='000000'
pack
If I understand this correctly, it deletes all rows/records where the code field has a value of 000000. Am I correct?
"Into SQL"
What do you mean by "SQL"?
Do you mean do the same thing using SQL in VFP for a VFP table? If so then:
use myTable exclusive
delete from myTable where code = '000000'
pack
But I doubt you are asking this, when you could do it by simply using the xBase code you wrote.
Do you mean how to that in an SQL backend like MS SQL server. postgreSQL, MySQL ...? If so then:
delete from myTable where code = '000000'
Note: In your code "all" is unnecessary but wouldn't do any harm.
Note2: In VFP code that you wrote, first line is "marking" the rows as "deleted" that have code value '000000'.
Second line really removes those rows from the table.
What version of foxpro?
delete from [table] where code = '00000'
pack
or
delete for code = '000000'
pack
both should work
I used identity column in oracle 12c:
col1 NUMBER GENERATED ALWAYS AS IDENTITY (START WITH 1 INCREMENT BY 1)
I use Spring + mybatis, how to get generated value, useGeneratedKeys seems doesn't work.
Thanks!
Anyway, the question has been asked and answered here.
You might not notice the generated value is not returned by the insert statement, but stored in the input parameter in the keyProperty.
I have a strange behavior: an agent called via an AJAX request should search documents to display in a calendar. For that reason I compute a search formula and then run the search method of my database in Lotusscript. This is the formula:
form="mholiday" | form="mserviceevent" | (form="mereignis" & co_status!="9") & #texttotime(#text(startdatetime)) >= [29.09.2014] & #texttotime(#text(enddatetime)) =< [10.11.2014]
Everything's fine on Domino on Windows but fails with "formula error" on a Linux machine. Am I missing something?
If I omit the term with the dates everything is fine, so this is the part that causes the error.
Try it with #ToTime() and #Date() instead. That might help to get away from local settings' influence on server:
... & #ToTime(startdatetime) >= #Date(2014; 9; 29) & ...
#ToTime() doesn't convert the field if it's a date time value already.
#Date doesn't depend on local settings whereas [29.09.2014] probably does.
I don't think it's a Linux problem, I think it's a data problem. It sounds like either a date format problem or a problem with the UNK table, used by full text search.
If the first document created on that server that had a field called "startdatetime" had a text value, then any search expects "startdatetime" to be a text value, even if there is another field in the database called startdatetime that is a date or the startdatetime field is subsequently changed to be a date. To confirm this, you can use the search bar and select the field. The operators it offers will confirm if it's expecting a date or a text value. See this answer for details on how to resolve "Query is not understandable" - Full text searching where field types have changed.
Alternatively, it may be a problem with the date format, as Knut says. In which case a test for 9/9/2014 would work but 29/9/2014 wouldn't.
I currently have a VM running Titan over a local Cassandra backend and would like the ability to use ElasticSearch to index strings using CONTAINS matches and regular expressions. Here's what I have so far:
After titan.sh is run, a Groovy script is used to load in the data from separate vertex and edge files. The first stage of this script loads the graph from Titan and sets up the ES properties:
config.setProperty("storage.backend","cassandra")
config.setProperty("storage.hostname","127.0.0.1")
config.setProperty("storage.index.elastic.backend","elasticsearch")
config.setProperty("storage.index.elastic.directory","db/es")
config.setProperty("storage.index.elastic.client-only","false")
config.setProperty("storage.index.elastic.local-mode","true")
The second part of the script sets up the indexed types:
g.makeKey("property").dataType(String.class).indexed("elastic",Edge.class).make();
The third part loads in the data from the CSV files, this has been tested and works fine.
My problem is, I don't seem to be able to use the ElasticSearch functions when I do a Gremlin query. For example:
g.E.has("property",CONTAINS,"test")
returns 0 results, even though I know this field contains the string "test" for that property at least once. Weirder still, when I change CONTAINS to something that isn't recognised by ElasticSearch I get a "no such property" error. I can also perform exact string matches and any numerical comparisons including greater or less than, however I expect the default indexing method is being used over ElasticSearch in these instances.
Due to the lack of errors when I try to run a more advanced ES query, I am at a loss on what is causing the problem here. Is there anything I may have missed?
Thanks,
Adam
I'm not quite sure what's going wrong in your code. From your description everything looks fine. Can you try the follwing script (just paste it into your Gremlin REPL):
config = new BaseConfiguration()
config.setProperty("storage.backend","inmemory")
config.setProperty("storage.index.elastic.backend","elasticsearch")
config.setProperty("storage.index.elastic.directory","/tmp/es-so")
config.setProperty("storage.index.elastic.client-only","false")
config.setProperty("storage.index.elastic.local-mode","true")
g = TitanFactory.open(config)
g.makeKey("name").dataType(String.class).make()
g.makeKey("property").dataType(String.class).indexed("elastic",Edge.class).make()
g.makeLabel("knows").make()
g.commit()
alice = g.addVertex(["name":"alice"])
bob = g.addVertex(["name":"bob"])
alice.addEdge("knows", bob, ["property":"foo test bar"])
g.commit()
// test queries
g.E.has("property",CONTAINS,"test")
g.query().has("property",CONTAINS,"test").edges()
The last 2 lines should return something like e[1t-4-1w][4-knows-8]. If that works and you still can't figure out what's wrong in your code, it would be good if you can share your full code (e.g. in Github or in a Gist).
