sql存储过程批量删除数据的语句

数据库操作教程 2022-09-23 16:48:31 转载来源: 网络整理/侵权必删

复制代码代码如下:CreatePROCEDUREBatch_Delete@TableNamenvarchar(100),--表名@FieldNamenvarchar(100)

复制代码 代码如下:

Create PROCEDURE Batch_Delete
@TableName nvarchar(100), --表名
@FieldName nvarchar(100), --删除字段名
@DelCharIndexID nvarchar(1000)
as
DECLARE @PointerPrev int
DECLARE @PointerCurr int
DECLARE @TId NVARCHAR(50), @sql NVARCHAR(1000)

Set @PointerPrev = 1
while (@PointerPrev < LEN(@DelCharIndexID))
Begin
Set @PointerCurr = CharIndex(',',@DelCharIndexID,@PointerPrev)
if(@PointerCurr>0)
Begin
SET @TId = cast(SUBSTRING(@DelCharIndexID, @PointerPrev, @PointerCurr - @PointerPrev) As NVARCHAR(50))
SET @sql = 'Delete From '+ @TableName +' Where '+ @FieldName + ' = '''+ @TID+''''
Exec(@Sql)
Print('======='+@TId+'=======sql'+@Sql)
SET @PointerPrev = @PointerCurr + 1
Print(@PointerPrev)
End
else
Begin
Print('break')
Break
End
End
--删除最后一个,因为最后一个后面没有逗号,所以在循环中跳出,需另外再删除
SET @TId = cast(SUBSTRING(@DelCharIndexID, @PointerPrev, LEN(@DelCharIndexID) - @PointerPrev + 1) As NVARCHAR(50))
SET @sql = 'Delete From '+ @TableName +' Where '+ @FieldName + ' = '''+ @TID+''''
Exec(@Sql)
Print('======='+@TId+'=======sql'+@Sql)
GO
