Dear all,

I have problem, the query as the following:

1. SELECT
2. CASE
3. WHEN PRODUCT_TYPE IN (SELECT PRODUCT_TYPE FROM PROD_T WHERE TYPE_COL='ACCEPT_OS')
4. THEN (SELECT RESULT FROM PROD_T WHERE PRODUCT_TYPE=OUTER.PRODUCT_TYPE)
5. ELSE 0
6. END ACCEPT_OS
7. FROM PRODUCTS_T OUTER

The problem in Line #5
The output from inner query is 'SRC' and it is single row. The outer table 'PRODUCTS_T' has SRC column.

I want specify the column name from inner query (line #5). It is like dynamic column name.

How can solve it?
