Executing Dynamic SQL with updateI have a temp table #Temp(id int, statement varchar, result int)
The statement column contains a prebuilt sql select statement e.g id statement Result 1 select count(*) from books where authorname like 'A%'. 2 select count(*) from books where authorname like 'J%'. I want run an update statement on the table so that i can set the result column to the result of the select statement in the statement column. e.g. update #temp set result = [statement result] I want to aviod cursors. Can this be done? Please help. This is in general, a poor approach. You can use certain undocumented
procedures ( in SQL 2000 ) to get this done, but it is complex, error prone and rarely worth it. Instead of having SQL statements as data values & updating #temp tables, consider using a view. Alternatively, depending on tables & wild card patterns involved, in some cases you might be able to resolve the problem with a single query with CASE. If you want a workable solution, pl. refer to www.aspfaq.com/5006 and post the required information along with a brief explanation of your requirements. In case you are wondering how to get the scalar result of a SELECT statement into a variable dynamically, refer to the procedure sp_ExecuteSQL in SQL Server Books Online. -- Anith
