Question

下面是用于DB表的REBUILD_INDEX的存储过程，它之前执行正常，但是当我现在检查它显示下面的错误时，

Msg 102，Level 15，State 1，Line 3
  ＆＃39;活动＆＃39;附近的语法不正确。

Msg 319，Level 15，State 1，Line 3
  关键字＆＃39;与＆＃39;附近的语法不正确。如果此语句是公用表表达式，xmlnamespaces子句或更改跟踪上下文子句，则前一个语句必须以分号结束

但是没有文字＆＃39;活动＆＃39;在存储过程中，并且不使用CTE。无法猜出这个突发问题的原因。谁能给我一个线索？

USE [DBName]
GO

/****** Object:  StoredProcedure [dbo].[REBUILD_INDEX]
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

ALTER PROCEDURE [dbo].[REBUILD_INDEX]
AS
BEGIN

DECLARE @TableName VARCHAR(255)
DECLARE @sql NVARCHAR(500)
DECLARE @fillfactor INT
SET @fillfactor = 80
DECLARE TableCursor CURSOR FOR
SELECT OBJECT_SCHEMA_NAME([object_id])+'.'+name AS TableName
FROM sys.tables
OPEN TableCursor
FETCH NEXT FROM TableCursor INTO @TableName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'ALTER INDEX ALL ON ' + @TableName + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'
EXEC (@sql)
FETCH NEXT FROM TableCursor INTO @TableName
END
CLOSE TableCursor
DEALLOCATE TableCursor

END

Answer 1

您应该添加分号并使用QUOTENAME：

ALTER PROCEDURE [dbo].[REBUILD_INDEX]
AS
BEGIN

DECLARE @TableName VARCHAR(255);
DECLARE @sql NVARCHAR(500);
DECLARE @fillfactor INT;
SET @fillfactor = 80;
DECLARE TableCursor CURSOR FOR
SELECT OBJECT_SCHEMA_NAME([object_id])+'.'+QUOTENAME(name) AS TableName
FROM sys.tables;
OPEN TableCursor;
FETCH NEXT FROM TableCursor INTO @TableName;
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'ALTER INDEX ALL ON ' + @TableName 
   + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ');';

PRINT @sql; -- debug only
EXEC (@sql);

FETCH NEXT FROM TableCursor INTO @TableName;
END;
CLOSE TableCursor;
DEALLOCATE TableCursor;

END;

我认为解析器错误WITH公共表格表达式来自WITH的{{1}}。

无论如何，我会使用Ola Hallengren's SQL Server Index and Statistics Maintenance Scripts而不是重新发明轮子。

Answer 2

“活动”几乎可以肯定是表名中的一部分，其中包含空格。在ALTER INDEX语句中的@TableName周围添加Quotename（..）。

＆＃39;活动＆＃39;附近的语法不正确在REBUILD_INDEX SP中
