It means you're calling a procedure, view or function from your procedure, and then from that proc calling another, etc 32 levels deep. Or it could be recursive with the proc calling itself.

Either way, you're going to have to track down where that is coming from and change the code so that the nesting level isn't anywhere close to that deep. There's no way to change the maximum nesting level.

In my SP, I'm trying to delete the No. of rows on the basis of some conditions.
So, that query is acting as recurssive. Is there a way to change that option.

That shouldn't be a recursive query unless you're explicitly calling a function from within itself. Post the query please?

I would put $ on it being recursive because there is a trigger on that table that edits/deletes other records in the table that then fire the trigger, etc. etc.

Hi,

Looks like my question is related to this thread.

I am trying to delete some rows in parent table and related rows in child tables. I am using below sp, but throwing error. Please help me to update the sp so that I can delete all related tables rows.



error:

Recursive row delete procedure.

It deletes all rows in the table specified that conform to the criteria selected,
while also deleting any child/grandchild records and so on. This is designed to do the
same sort of thing as Access's cascade delete function. It first reads the sysforeignkeys
table to find any child tables, then deletes the soon-to-be orphan records from them using
recursive calls to this procedure. Once all child records are gone, the rows are deleted
from the selected table. It is designed at this time to be run at the command line. It could
also be used in code, but the printed output will not be available.

It's worth to notice that laddu4700 already posted his question in a different thread.

Thanks for this suggestion, I had a similar problem and i was able to resolve it after removing a proc call within the same procedure. Now it's not throwing any error when executing the proc.
