Hello all,

I'm attempting to query multiple clob fields and just using the normal like '%whatever text%' falls way short of my needs.

I found the Oracle Text as an option and after some pain I am starting to get my legs under me on this.

I am however getting an error when I attempt to create an index on the first of the clob fields in the script below:

CREATE INDEX ctx_narr_test ON narra_data_test(narr_final) INDEXTYPE IS CTXSYS.CTXCAT PARAMETERS ('index set narra_test_iset');

Should I user a different index type than CTXSYS.CTXCAT?

Thanks,

What error are you getting? Let me guess:

ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-10509: invalid text column: NARR_FINAL
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.CATINDEXMETHODS", line 97

If so, you may want to consider a CONTEXT index due to the fact that CTXCAT only supports CHAR or VARCHAR2 data types.

Yes, apparently CONTENT is what I needed to use.

Thanks
