Hi,
can the records from tables be deleted by joining them... but i got error while trying it in QMF....
can anyone advice is it a possibility.... i thought of another way like declaring the join as cursor , open the cursor and delete current of cursor...
but my environment is not allowing me to execute such try.... |

Probably not, but that depends on exactly what you want to do.
Suggest you rethink your question. . . Keep in mind that your questin is completely clear to you, but it may not be clear to those who read it and would like to help.
If you show some rows from the 2(?) tables and what you want as the result of running your query, someone may have a suggestion. |

had you looked up the sqlcode or spent 3 minutes in a db2 manual you would learned that join cursors are read only.
can't update a join. (a delete is an update). |

Probably you can code the requirement in a delete statement, but you're asking the wrong question.
It 's like asking : "Can i saw a board in two with a screwdriver?"
probably need something like WHERE EXISTS. |
