Method Detail

tearDown

public void tearDown()
              throws java.sql.SQLException

Description copied from class: BaseJDBCTestCase

Tear down this fixture, sub-classes should call super.tearDown(). This cleanups & closes the connection if it is open and any statement objects returned through the utility methods.

Overrides:

tearDown in class BaseJDBCTestCase

Throws:

java.sql.SQLException

testBlobLength

private void testBlobLength(boolean lengthless,
                            int extraLen)
                     throws java.sql.SQLException,
                            java.io.IOException,
                            java.lang.IllegalArgumentException,
                            java.lang.IllegalAccessException,
                            java.lang.reflect.InvocationTargetException

Insert a blob and test length.

Parameters:

lengthless - if true use the lengthless setBinaryStream api

Throws:

java.sql.SQLException

java.io.IOException

java.lang.reflect.InvocationTargetException

java.lang.IllegalAccessException

java.lang.IllegalArgumentException

testBlobLength

public void testBlobLength()
                    throws java.sql.SQLException,
                           java.io.IOException,
                           java.lang.IllegalArgumentException,
                           java.lang.IllegalAccessException,
                           java.lang.reflect.InvocationTargetException

Test the length after inserting with the setBinaryStream api that takes length. In this case the length will be encoded at the begining of the stream and the call should be fairly low overhead.

Throws:

java.sql.SQLException

java.io.IOException

java.lang.reflect.InvocationTargetException

java.lang.IllegalAccessException

java.lang.IllegalArgumentException

testBlobLengthWithLengthlessInsert

public void testBlobLengthWithLengthlessInsert()
                                        throws java.sql.SQLException,
                                               java.io.IOException,
                                               java.lang.IllegalArgumentException,
                                               java.lang.IllegalAccessException,
                                               java.lang.reflect.InvocationTargetException

Test the length after inserting the blob value with the lengthless setBinaryStream api. In this case we will have to read the whole stream to get the length.

Throws:

java.sql.SQLException

java.io.IOException

java.lang.reflect.InvocationTargetException

java.lang.IllegalAccessException

java.lang.IllegalArgumentException

testBlobLengthTooLongDerby961

public void testBlobLengthTooLongDerby961()
                                   throws java.sql.SQLException,
                                          java.io.IOException,
                                          java.lang.IllegalArgumentException,
                                          java.lang.IllegalAccessException,
                                          java.lang.reflect.InvocationTargetException

Simple test to excercise message 22001 as described in DERBY-961.

Throws:

java.sql.SQLException

java.io.IOException

java.lang.IllegalArgumentException

java.lang.IllegalAccessException

java.lang.reflect.InvocationTargetException
