如何判斷表中是否存在SQL自增列呢？這是很多人都提到過(guò)的問(wèn)題，下面就為您介紹判斷表中是否存在SQL自增列的實(shí)現(xiàn)方法，供您參考。

判斷Table是否存在SQL自增列(Identity column)：

declare @Table_name varchar(60)

set @Table_name = '';

if Exists(Select top 1 1 from sysobjects
           Where objectproperty(id, 'TableHasIdentity') = 1
             and upper(name) = upper(@Table_name)
         )
     select 1
else select 0

-- or

if Exists(Select top 1 1 from sysobjects so
           Where so.xtype = 'U'
             and upper(so.name) = upper(@Table_name)
             and Exists(Select Top 1 1 from syscolumns sc
                         Where sc.id = so.id
                           and columnproperty(sc.id, sc.name, 'IsIdentity') = 1
                       )
         )
       select 1
else select 0

判斷Table是否存在自增列(Identity column),并查出自增列相關(guān)數(shù)據(jù)：

declare @Table_name varchar(60)
set @Table_name = '';
