由 我们两清 提交于 2019-12-10 14:32:08
问题 In MS SQL Server, I'm using a global temp table to store session related information passed by the client and then I use that information inside triggers. Since the same global temp table can be used in different sessions and it may or may not exist when I want to write into it (depending on whether all the previous sessions which used it before are closed), I'm doing a check for the global temp table existence based on which I create before I write into it. IF OBJECT_ID('tempdb..##VTT

问题 What is the difference between local and global temporary tables in SQL Server? 回答1: I find this explanation quite clear (it's pure copy from Technet): There are two types of temporary tables: local and global.
