问题描述
我希望在将存储过程导入为函数导入时从存储过程中获取列信息。但我没有获得复杂存储过程的列信息。它包含动态查询。如何解决此问题以从存储过程中获取选择结果。
I want to get columns information from stored procedure while importing stored procedure as function import. But I am not getting columns information for complex stored procedure. It contains dynamic query. How can i solve this problem to get select result from stored procedure.

推荐答案
你将无法获得专栏由于动态SQL，来自存储过程的信息。您可以做的是将动态SQL的结果存储在临时表或变量表中，并将该表中的选择作为最后一个语句。
如果问题是due to columns dynamically being added to the SELECT statement in the dynamic SQL, then there is nothing you will be able to do.
You won't be able to get column information from the stored procedure because of the dynamic SQL. What you can do is store your results of the dynamic SQL in a temp or variable table and make your select from that table as the last statement.
If the issue is due to columns dynamically being added to the SELECT statement in the dynamic SQL, then there is nothing you will be able to do.
