Question

We are using the jdbc-odbc bridge to connect to an MS SQL database. When perform inserts or updates, strings are put into the database padded to the length of the database field. Is there any way to turn off this behavior (strings should go into the table without padding)?

For reference, we are able to insert field values that don’t contain the padding using the SQL management tools and query analyzer, so I’m pretty sure this is occuring at the jdbc or odbc layer of things.

EDIT: The fields in the database are listed as nvarchar(X), where X = 50, 255, whatever

EDIT 2: The call to do the insert is using a prepared statement, just like:

PreparedStatement stmt = new con.prepareStatement('INSERT INTO....'); stmt.setString(1, 'somevalue'); 

Answer 1

How are you setting the String? Are you doing?:

PreparedStatement stmt = new con.prepareStatement('INSERT INTO....'); stmt.setString(1, 'somevalue'); 

If so, try this:

stmt.setObject(1, 'somevalue', Types.VARCHAR); 

Again, this is just guessing without seeing how you are inserting.
