cassandra - java.lang.NumberFormatException: For input String - cassandra

I have another problem with cassandra.. I have export a table in Mysql in .csv format and import it in Cassandra.the Mysql table contains filds date and time of types Date and Time. I define these fields as varchar in cassandra. so when I import the .csv file and execute the below query, it shows me an error:
my query:
ResultSet rs = stmnt.ExecuteQuery("Select * from station info where IDstation = 1011 and IDinfo = 18412:);
while (rs.next) {
System.out.println(rs1.getFloate(1) + " " +
rs1.getString(2) + " " +
rs1.getFloate(3) + " " +
rs1.getString(4) + " " +
rs1.getInt(5) + " " +
rs1.getInt(6) + " " +
rs1.getString(7) + " " +
rs1.getFloate(8));
}
the 7th field in print command is date..
and the error is:
java.lang.NumberFormatException: For input String: "6/2/1962"
at org.apache.cassandracql.jdbc.cassandraResultSet.getInt(CassandraResultSet.java:619)
at org.apache.cassandracql.jdbc.cassandraResultSet.getInt(CassandraResultSet.java:590)
I can not understand what it says... can anyone help me please?

Read what the stacktrace is telling you carefully
java.lang.NumberFormatException: For input String: "6/2/1962"
at org.apache.cassandracql.jdbc.cassandraResultSet.getInt(CassandraResultSet.java:619)
at org.apache.cassandracql.jdbc.cassandraResultSet.getInt(CassandraResultSet.java:590)
The error you are getting is to do with an attempt to retrieve a string as a integer.

Make sure that the date column is coming at 7th position only and not anywhere else. I suggest you to improve your query by specifying the column names. For eg.,
SELECT Col1, Col2... FROM Table
This avoids confusion of column order.

Breakline in ssis message does not work

I am creating a message inside a string using a Script task
The code would look like this:
Message = Description +"\n" + Message;
The idea is to receive a message like this:
Description
Description
and so on
Within a messagebox I can see this result, but when I open the mail, the message is composed of one single line:
Description1 Description2
I have also changed "\n" for "\n\r", Environment.NewLine. But it didn't work.
Could you explain me what am I doing wrong?
You need to typecast it as below:
(DT_STR,2,1252)"\r\n"
For example...the below expression in Execute SQL task is dynamic SQL
"INSERT INTO [dbo].[OBJ_COUNT]([OBJ_NAME], [OBJ_COUNT]) VALUES ( " + "'EMPLOYEE_MASTER', " + (DT_STR, 10, 1252) (#[User::EMP_MAST_COUNT])+" );" + (DT_STR,2,1252)"\r\n" + "GO " + (DT_STR,2,1252)"\r\n" + "INSERT INTO [dbo].[OBJ_COUNT]([OBJ_NAME], [OBJ_COUNT]) VALUES ( " + "'DEPT_MASTER', " + (DT_STR, 10, 1252) (#[User::DEPT_MAST_COUNT])+" );" + (DT_STR,2,1252)"\r\n"+ "GO "
And will give output as below...
INSERT INTO [dbo].[OBJ_COUNT]([OBJ_NAME], [OBJ_COUNT]) VALUES ( 'EMPLOYEE_MASTER', 2514);
GO
INSERT INTO [dbo].[OBJ_COUNT]([OBJ_NAME], [OBJ_COUNT]) VALUES ( 'DEPT_MASTER', 2541);
GO
Try "\n\n" . This works but adds an extra line break. In most cases it is adequate.

sudden change in string value during a browse value change

During a Value-Change inside a browse, my string value suddenly changes, specifically the string(9) will change to string(0).
sample:
in my combo-box, i used a list-item-pair with following code:
cb-name:LIST-ITEM-PAIRS = ?.
cb-name:DELIMITER = '?'.
FOR EACH employee WHERE employee.date-resigned = ? NO-LOCK BY employee.employee-no.
cb-name:ADD-LAST(TRIM(STRING(employee.employee-no, '99999999') + " - " + employee.last-name + ", " + employee.first-name + " " + SUBSTRING(employee.middle-name,1,1)) + ".",employee.employee-no).
END.
cb-name:SCREEN-VALUE = cb-name:ENTRY(1).
in the value-changed of browse:
ASSIGN cb-name:SCREEN-VALUE =
STRING(TRIM(STRING(employee.employee-no, '99999999') + " - " + employee.last-name + ", " + employee.first-name + " " + SUBSTRING(employee.middle-name,1,1)) + "." ,
STRING(employee.employee-no, '99999999')).
if the employee no has a string value of 9, progress will change it to 0.. producing an error message that has an invalid value..
ex: from 819001 /*correct*/ to 810001 /*incorrect*/
if there is no string(9), it will display like:818002
if i message the STRING(employee.employee-no, '99999999')), it will display the correct string value
Version doesn't matter in this case, apparently. I just simulated it in 10.2B08 using a temp-table with the named tables. The problem is when you're assigning the screen-value to the combo you're trying to convert the whole string (employee-no + names + separators) into format 99999999.
Since your combo is list-item-pairs
('Whatever I want it to display','the real value',
'and so on display' , 'and so forth value')
your solution is to assign the screen value just to the real value, disregard the label. In other words, as simple as changing your value-changed code to
ASSIGN cb-name:SCREEN-VALUE = STRING(employee.employee-no, '99999999') .
It worked for me. Let me know if you are still having trouble with it.

Passing array from Java to VBScript

I have two questions:
1. If we can pass an array to VBSCript using java. I am able to pass single variables to VBSCript using following command
Runtime.getRuntime().exec("wscript openChartsDevice.vbs " + fileName + " " + range);
But when I pass a String array, it says type mismatch. I am catching the array passed in
Dim arr()
any Suggestions?
Edit 1 Following question has been answered
2. I am using following Vbscript to create chart in excel
Dim oExl,excelPath,objWriteSheet,objWriteWorkbook
Dim oMychartProcs
Set oExl=CreateObject("Excel.Application")
Set objWriteWorkbook = oExl.Workbooks.Open("SomeExcelfile.xlsx")
Set objWriteSheet = objWriteWorkbook.Worksheets(1)
Set oMychartProcs = objWriteWorkbook.Charts.Add
oMychartProcs.SetSourceData objWriteSheet.Range(Cells(2,1),Cells(7,6))
oMychartProcs.ChartType = 4
oMychartProcs.Name = "ChartName"
oMychartProcs.Activate
I have given the range as A2:F7. when I enter
oMychartProcs.SetSourceData objWriteSheet.Range("A2:F7")
the chart is created perfectly but when I use the
Range(Cells(2,1),Cells(7,6))
whole excel sheet is converted to chart.
I want to provide the range through parameters so I want above formula to work. I've searched a lot and could not find a definitive way for it. Thank you.
You can not pass array as an object. But you can pass its elements as string parameters to the vbscript function with a space as the delimiter.
openChartsDevice.vbs " + fileName + " " + arg[0] + " " + arg[1] + " " + arg[2].....
You can a create a method in java to pass an array and return a string
arg[0] + " " + arg[1] + " " + arg[2].....
Another Approach: Create a file with input parameters. Update your VBScript to refer to that input file to get the parameters instead of looking for command line arguments.
I don't know JScript. But the way to get in VBScript the same thing.
For Each thing in Array()
A = A & thing & " "
Next
You are actually asking how to turn an array into a delimited string not a vbscript array.
See this article which your question title implies you are interested in.

Using hash sign (#) in the Excel sheet name

I'm trying to solve an issue I have when I'm trying to use OLE DB for reading Excel files.
I found that the problem is because there is a hash mark (#) in the sheet name.
Unfortunately, I can't rename the sheet.
So after some tries, I've succeeded to read a full sheet by adding quotation marks ('):
Before
Select * from [" + sheetName + "$];
After (working)
Select * from ['" + sheetName + "$'];
But then I got stuck when trying to read a range from the sheet with the OLE DB feature:
Select * from [" + sheetName + "$" + fromCell + ":" + toCell + "];
When I try to send this command, it's seems like the # is replaced by . and then it cannot find the sheet.
I've tried many combination and escape codes and didn't find any solution. How can I access this file?
Your final output should look like this
'MySheet$A1:B2'
So your select should be
var SheetName = "MySheet";
var fromCell = "A1";
var toCell = "B2";
var sql = "Select * from ['" + SheetName + "$" + fromCell + ":" + toCell + "']";
Console.WriteLine(sql);
// Output
// Select * from ['MySheet$A1:B2']
Also consider parametrising your sql for better readability and also preventing sql code injection. You can find a guide for how to do it at OleDbCommand.Parameters.

The expression contains an invalid string constant: '

this code is in Textbox Change event.
dds.Tables["IncomeGenerator"].DefaultView.RowFilter = "' Income LIKE '" + txtSearch.Text + "' OR Expenses LIKE '" + txtSearch.Text + "' OR Date LIKE '" + txtSearch.Text + "' OR Balance LIKE '" + txtSearch.Text + "' OR Description LIKE '" + txtSearch.Text + "'";
when i run it, it gives a error saying " The expression contains an invalid string constant: '. "
can someone help me.
my Income, Expenses and Balance is Data Type Float and Date is Datetime. i hope it may help. can someone guide me with the mistake and help me
It's hard to tell for sure, but sometimes when I copy code from a web page or word processor, I inadvertently include a "book quote" (http://en.wikipedia.org/wiki/Quotation_mark_glyphs) that screws things up.
It looks like there may be some in the sample you posted. Try making sure all the quotes are the straight-up-and-down quotes, and not the begin-end "book quotes".
