Method Detail

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

testDerby4477_3645_3646_Repro_lowmem

public void testDerby4477_3645_3646_Repro_lowmem()
                                          throws java.sql.SQLException,
                                                 java.io.IOException

Tests that a blob can be safely occur multiple times in a SQL select and test that large objects streams are not being materialized when cloned.

See DERBY-4477.

Throws:

java.sql.SQLException

java.io.IOException

testDerby5752DoubleMaterialization

public void testDerby5752DoubleMaterialization()
                                        throws java.lang.Exception

Test that a BLOB that goes through the sorter does not get materialized twice in memory. It will still be materialized as part of the sorting, but the fix for DERBY-5752 prevents the creation of a second copy when accessing the BLOB after the sorting.

Throws:

java.lang.Exception
