[Quoted] hi all,

i got a big problem and hope, somebody can help. i have to create a dynamic delete script which has to run once a day. the script should find all tables containing a specific column (DEL_YN). then it should physically delete all records in this tables with value 'Y' in that column which indicates that the row has been 'deleted' by a user.

i know i can get a cursor with all table-names by the sys.all_objects joining with the sys.all_tab_columns to determine if the specific column exists in the table.
and i do know i can use this cursor to delete the records in all the tables.

what i do not know is how can i assure that the delete script runs through the tables in the right order (i.e. dependencies, constraints......)??

can anybody help?

thanks in advance!

kind regards,
