hi all
i am using db2 as my back end
when i issue the below lines its working fine in the command editor


select * from mytable where birth_date = '03/01/1997'

but when i tried to execute the above query using prepared statement i am getting error

in the prepared statement i am setting it as string.

stmtObj.setString(0,strBirthDate);

strBirthDate is string which holds '03/01/1997',
i donno why it is not executing when using the prepared statement, the same thing works out when i build the query and execute it as a simple stmt.

Any pointers will be greatly appreciated.

What is the error that you are getting? Just a thought but, maybe db2 is looking for a certain date format. I have seen the format YYYY-MM-DD HH:MM:SS.ms

I assume your birth_date column in DB2 is Date data type. In this case I believe you would need to use setDate() not setString().

The PreparedStatement javadoc has this to say

"Note: The setter methods (setShort, setString, and so on) for setting IN parameter values must specify types that are compatible with the defined SQL type of the input parameter. For instance, if the IN parameter has SQL type INTEGER, then the method setInt should be used.

If arbitrary parameter type conversions are required, the method setObject should be used with a target SQL type."

so possibly you could use setObject(0, strBirthDate, java.sql.Types.DATE)

Jim,

Yes, DB2 might look for some own format for date, but
select * from mytable where birth_date = '03/01/1997'
is working fine, thats why i am passing the date of this format and execute it using the prepared statement.
