Need help on DATA_REMAP procedure.

Question

Hi All,
I am using data pump APIs to perform export and import. But “data_remap” procedure is throwing exceptions.

We have a set of tables, whose data needs to be exported. We have following constraints to perform export:
1) Only the tables that contains a column (lets say test_id) needs to be exported. We are fetching these tables by querying "all_tab_columns" view as {select table_name from all_tab_columns where column_name = 'test_id' and owner = user} This query fetches around 40 tables.
2) From this set of tables we need only the data which satisfy the condition {select * from <tablename> where test_id = 10}.
3) Now we need to replace test_id value 10 with -1.
Create or replace package body TESTPACKAGE as
function SetTestID(p_TestId number) return number is
v_TestId number := -1;
begin
return v_TestId;
end;
procedure exportData is
h1 number; -- Data Pump job handle
begin
h1 := dbms_datapump.open('EXPORT',
'TABLE',
null,
'EXAMPLE1',
'LATEST');
dbms_datapump.add_file(h1,
'example1.dmp',
'EXPORT');
dbms_datapump.metadata_filter(handle => h1,
name => 'NAME_EXPR',
value => 'IN (select TABLE_NAME from ALL_TAB_COLUMNS A where A.COLUMN_NAME = TEST_ID'' and owner = user and not (A.TABLE_NAME like ''PV%'') and not (A.TABLE_NAME like ''IV%'') and not (A.TABLE_NAME like ''IMV%'') and not (A.TABLE_NAME like ''BIN$%''))',
object_type => 'TABLE');
dbms_datapump.data_filter(handle => h1,
name => 'SUBQUERY',
value => 'WHERE TEST_ID = 10',
table_name => null,
schema_name => null);
dbms_datapump.data_remap(handle => h1,
name => 'COLUMN_FUNCTION',
table_name => 'TABLE1',
column => 'TEST_ID',
function => 'TESTPACKAGE.SETTESTID(10)',
schema => 'ATOM606');
dbms_datapump.start_job(h1);
end;
end;
But here data_remap procedure is giving below error
+"ORA-39232: invalid remap function: TESTPACKAGE.SETTESTID(10)"+
Can anyone help how to use this data_remap procedure and how to pass the value to the function parameter? And also how to specify the whole table list?
Any help is highly appreciated.Thanks in advance :)

Answer 1

I think there is some limit on the length of this parameter. It was not accepting the whole string <SchemaName>.<TableName>.Test_Id.
So i tried with
dbms_datapump.data_remap(handle => h1,
name => 'COLUMN_FUNCTION',
table_name => 'TABLE1',
column => 'TABLE1.TEST_ID',
function => 'ATOM606.TESTPACKAGE.SETTESTID',
schema => 'ATOM606');
But it doesn't make any difference, still getting the same error.
I also tried by passing the column name as input argument to the SETTESTID function, hoping for some miracle, but even that doesn't make any difference.
