Hi all,

I got ORA-04091: table mutating problem. Here is the case: select from table A and insert them into table B. A trigger is used to check that new DATE must be later than every DATE in B. So I open an cursor, loop through cursor to compare new DATE value.

If I tested using hard coded value, the trigger works; if do a insert ... select, I got ORA-04091.

I looked through metalink, didn't see anything that can help.

Thank you in advance.

Leslie
