Oracle中的流水线函数

Question

I have created a pipelined function in Oracle. I need to use this function to get a column value in table format; for that I have written this query:

 SELECT * 
   FROM TABLE (
               parse_comma_delimited(
                                      ( SELECT SOURCE_COLUMNS 
                                          FROM BW_SUPERMERGE_RULES 
                                         WHERE RULE_NAME = 'SQL2CUB' 
                                      ), ',')
                                    )
               );

But I am getting the following error:

ORA-00933: SQL command not properly ended
00933. 00000 - "SQL command not properly ended"

Can any one suggest me to how to fix this?

Answer 1

I think your parenthesis is not properly matched, I've edited the code

SELECT * 
  FROM TABLE (parse_comma_delimited (SELECT SOURCE_COLUMNS 
                                     FROM BW_SUPERMERGE_RULES 
                                     WHERE RULE_NAME = 'SQL2CUB', ','));

Basically these kind of errors are for syntax.

I think this will work; if your function parse_comma_delimited is correct.

SELECT * 
              FROM TABLE (
    parse_comma_delimited(
    ( SELECT SOURCE_COLUMNS  
        FROM BW_SUPERMERGE_RULES  
       WHERE RULE_NAME = 'SQL2CUB' 
    ), ',')
   );
