Method Detail

initializeConnection

protected void initializeConnection(java.sql.Connection conn)
                             throws java.sql.SQLException

Sets the auto commit to false.

Overrides:

initializeConnection in class BaseJDBCTestCase

Parameters:

conn - Connection to be intialized

Throws:

java.sql.SQLException - Error setting the initial state.

suite

public static junit.framework.Test suite()

Returns the implemented tests.

Returns:

An instance of Test with the implemented tests to run.

setUp

protected void setUp()
              throws java.lang.Exception

Bug only happens when autocommit is off.

Overrides:

setUp in class junit.framework.TestCase

Throws:

java.lang.Exception

testBug4356

public void testBug4356()
                 throws java.sql.SQLException

Check fix for Bug4356 - Prepared statement parameter buffers are not cleared between calls to executeUpdate() in the same transaction. Using a prepared statement to insert data into a table using a sub select to get the data from a second table. The prepared statement doesn't seem to clear it's buffers between execute statements within the same transaction.

Throws:

java.sql.SQLException
