我目前是sql server的新手。
我在visual studio 2010 express的帮助下使用存储过程。
当我发现这个错误时，我正在sql server中试验存储过程，这非常烦人：
关键字“IF
附近的语法不正确UPDATE [table_name]
SET
[delete_datetime] = CURRENT_TIMESTAMP,
[delete_user_record_id] = 2
WHERE [table_name].[record_id] = 2
这是我的存储过程函数。它是在我当前的表上更新时间戳：
USE [MGroupIS]
GO
/****** Object: StoredProcedure [dbo].[iSP_SET_DATA_INFORMATION] Script Date: 02/01/2016 14:40:26 ******/
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[SP_SET_DATA_INFORMATION]
--Paramateres
AS
DECLARE @sql AS NVARCHAR(4000)
DECLARE @pFlag AS VARCHAR(6)
SET @pFlag = @flag
--IF Delete
IF @pFlag = 'DELETE'
BEGIN
SET @sql = 'UPDATE [' + @tableName + '] ' + CHAR(13) +
' SET ' + CHAR(13) +
' [delete_datetime] = CURRENT_TIMESTAMP, ' + CHAR(13) +
' [delete_user_record_id] = ' + CAST(@userRecordID AS VARCHAR(20)) + CHAR(13) +
' WHERE [' + @tableName + '].[' + @keyField + '] = ' + CAST(@recordID AS VARCHAR(20))
END
ELSE
BEGIN
SET @sql = 'UPDATE [' + @tableName + '] ' + CHAR(13) +
' SET ' + CHAR(13) +
' [edit_datetime] = CURRENT_TIMESTAMP, ' + CHAR(13) +
' [edit_user_record_id] = ' + CAST(@userRecordID AS CHAR(3))
END
EXEC sp_executeSQL @sql
PRINT @sql
我从另一个存储过程（ISP_CFG_ACCESS_RIGHT_QUERY）调用存储过程：
ELSE IF @action = 'SAVE'
--SAVE Action
BEGIN
--If saved
IF @removeUnsaved = 0
BEGIN
UPDATE [CFG_ACCESS_RIGHT]
SET [CFG_ACCESS_RIGHT].[NAME] = '' + @name + '',
[CFG_ACCESS_RIGHT].[NOTE] = '' + @note + ''
WHERE [CFG_ACCESS_RIGHT].[RECORD_ID] = @recordID
DELETE FROM [CFG_ACCESS_RIGHT_DETAIL]
WHERE [CFG_ACCESS_RIGHT_DETAIL].[access_right_record_id] = @recordID
SET @sql = 'INSERT INTO [CFG_ACCESS_RIGHT_DETAIL] ' + CHAR(13) +
'SELECT * FROM [' + @tempTable + '] ' + CHAR(13) +
' WHERE [' + @tempTable + '].[delete_datetime] IS NULL;'
EXEC sp_executeSQL @sql
EXEC [ISP_SET_DATA_INFORMATION]
'CFG_ACCESS_RIGHT',
'record_id',
@userRecordID,
@recordID,
@voidStatus,
@voidReason,
@flag,
0
EXEC [ISP_SET_DATA_INFORMATION]
'CFG_ACCESS_RIGHT_DETAIL',
'access_right_record_id',
@userRecordID,
@recordID,
@voidStatus,
@voidReason,
@flag,
0
END
--If leave without saving
ELSE
BEGIN
EXEC [ISP_SET_DATA_INFORMATION]
'CFG_ACCESS_RIGHT',
'record_id',
@userRecordID,
@recordID,
@voidStatus,
@voidReason,
'DELETE',
0
END
请帮忙。 先谢谢你。
编辑1：隔离潜在的有问题的部分。请帮忙
答案 0 :(得分：0)
过程中的动态DROP表语句在语法上是错误的。
应该是这样的，
IF OBJECT_ID('tablename', 'U') IS NOT NULL
DROP TABLE tablename;
除此之外，T-SQL中的语法错误也很少。我修好了。
请参阅此代码，
IF @pFlag = 'DELETE'

END
