Oracle Query Does Not Work In SSIS

Hello All,

I am trying to run the below query in SSIS, However it does not work, but when I try to run the same query in Oracle client it works fine. Here is the following query:

select 'AAA-'||OWNER AS SOURCE,
table_name,
column_name,
SUBSTR(data_type,1,50) DATA_TYPE ,
SUBSTR(decode(data_type,'NUMBER', DATA_PRECISION, DATA_LENGTH),1,20) DATA_LENGTH
from all_tab_cols
where owner='XXX'
ORDER BY TABLE_NAME, COLUMN_ID

Here ARE the following errorS I get when running from SSIS:

[ORA_AAA_XXX [147]] Error: There was an error with output column "SOURCE" (612) on output "OLE DB Source Output" (157). The column status returned was: "The value could not be converted because of a potential loss of data.".

[ORA_AAA_XXX [147]] Error: The "output column "SOURCE" (612)" failed because error code 0xC0209072 occurred, and the error row disposition on "output column "SOURCE" (612)" specifies failure on error. An error occurred on the specified object of the specified component.

Any help?

Regards,

Raju
