判断当表存在标识列的时候就要允许将显式值插入表的标识列中，设置：
Set Identity_insert TableName Off
判断数据类型：
如，varchar,char,datetime,nvarchar,nchar，uniqueidentifier时候，在insert字段中就要增加双引号，否则就不加，
自动生成insert数据的SQL脚本
。
Use Test<br />Go<br />Declare<br /> @Table1 nvarchar(128),<br /> @Table2 nvarchar(128),<br /> @Sql1 nvarchar(4000),<br /> @Sql2 nvarchar(4000),<br /> @SqlIdentityInsert nvarchar(512)<br />Set @Table1='DutyHistory' --源表<br />Set @Table2='Duty' --目标表<br />IF Object_id(@Table1,'U') Is Null<br /> Return<br />If Isnull(@Table2,'')=''<br /> Set @Table2=@Table1<br />Set @SqlIdentityInsert=''<br />If Exists(Select 1 From sys.columns Where Object_id=Object_id(@Table1,'U'))<br /> Set @SqlIdentityInsert='Select ''Set Identity_Insert '+@Table2+' On '''<br />Select<br /> @Sql1=Isnull(@Sql1+',',' Insert Into '+@Table2+' (')+Quotename(name),<br /> @Sql2=Isnull(@Sql2+'+'',''+','Select @Sql1+'' Select ''')+'+Case When '+Quotename(name)+' Is null Then ''null'' Else '+<br /> Case When user_type_id In(175,61,239,231,58,98,36,167,241) Then '''''''''+Rtrim('+Quotename(name)+')+''''''''' Else 'Rtrim('+Quotename(name)+')' End +' End'<br />From sys.columns<br />Where Object_id=Object_id(@Table1,'U')<br />Set @Sql1=@Sql1+')'<br />Set @Sql2= 'Select Convert(nvarchar(max),''If Object_id('''''+@Table2+''''',''''U'''') Is Null Return;'') As SqlInsert Union All '+<br /> @SqlIdentityInsert+' Union All '+<br /> @Sql2+' From '+Quotename(@Table1)+Case @SqlIdentityInsert When '' Then '' Else ' Union All ' End+<br /> Replace(@SqlIdentityInsert,' On ',' Off')<br />Exec sp_executesql @Sql2,N'@Sql1 nvarchar(4000)',@Sql1
Result:
