The type conversion rules established in SQL 2000 say that when two types meet, the type with lowest precedence is converted to the other, if an implicit conversion exists. You may ask: what if we want to have different definitions of his temp table, like this:: CREATE PROCEDURE doubletmp @i int AS IF @i = 0 CREATE TABLE #tmp(a int NOT NULL) ELSE CREATE TABLE #tmp(b int NOT NULL). You no longer get an error about the missing table, but the procedure creates just fine. What would happen here when strict checks are in force?
