Question

我在我的SQL Server 2005 SP4中遇到问题，因为我的re-jndexing计划作业因上个月错误导致特定数据库失败：

Msg 102, Level 15, State 1, Line 1
Incorrect syntax near '-'.
Msg 319, Level 15, State 1, Line 1
Incorrect syntax near the keyword 'with'. If this statement is a common table expression or an xmlnamespaces clause, the previous statement must be terminated with a semicolon.

但是我能够使用相同的查询重新索引其他数据库...而且我能够在我的测试环境中使用相同的查询重新索引相同的数据库。

查询重新索引。

DECLARE @Database VARCHAR(255)   
DECLARE @Table VARCHAR(255)  
DECLARE @cmd NVARCHAR(500)  
DECLARE @fillfactor INT 

SET @fillfactor = 90 

DECLARE DatabaseCursor CURSOR FOR  
SELECT name FROM master.dbo.sysdatabases   
WHERE name like ('Database_Name') 
ORDER BY 1  

OPEN DatabaseCursor  

FETCH NEXT FROM DatabaseCursor INTO @Database  
WHILE @@FETCH_STATUS = 0  
BEGIN  

   SET @cmd = 'DECLARE TableCursor CURSOR FOR SELECT table_catalog + ''.'' + table_schema + ''.'' + table_name as tableName   
                    FROM ' + @Database + '.INFORMATION_SCHEMA.TABLES WHERE table_type = ''BASE TABLE'''   

   -- create table cursor  
   EXEC (@cmd)  
   OPEN TableCursor   

   FETCH NEXT FROM TableCursor INTO @Table   
   WHILE @@FETCH_STATUS = 0   
   BEGIN   

       -- SQL 2005 command  
       SET @cmd = 'ALTER INDEX ALL ON ' + @Table + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'  
       EXEC (@cmd)  

       FETCH NEXT FROM TableCursor INTO @Table   
   END   

   CLOSE TableCursor   
   DEALLOCATE TableCursor  

   FETCH NEXT FROM DatabaseCursor INTO @Database  
END  
CLOSE DatabaseCursor   
DEALLOCATE DatabaseCursor

将EXEC (@cmd)替换为SELECT (@cmd)。看看结果。我认为你的表名有一个破折号。

更改查询

SET @cmd = 'ALTER INDEX ALL ON ' + QUOTENAME(@Table) + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')'  
       EXEC (@cmd)

您应该对所有对象使用QUOTENAME()。它会在对象名称周围放置括号[]。
