填充因子 - SQL Server，是否有方法在数据库，服务器或模式中设置填充因子？

Question

我知道你可以设置一个默认的填充因子，但是我想在整个服务器上将现有的填充因子改回默认值。

Answer 1

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 NOT IN ('master','msdb','tempdb','model','distribution') 
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 

     IF (@@MICROSOFTVERSION/POWER(2, 24) >= 9) 
     BEGIN 
      -- SQL 2005 or higher command 
      SET @cmd = 'ALTER INDEX ALL ON ' + @Table + ' REBUILD WITH (FILLFACTOR = ' + CONVERT(VARCHAR(3),@fillfactor) + ')' 
      EXEC (@cmd) 
     END 
     ELSE 
     BEGIN 
      -- SQL 2000 command 
      DBCC DBREINDEX(@Table,' ',@fillfactor) 
     END 

     FETCH NEXT FROM TableCursor INTO @Table 
    END 

    CLOSE TableCursor 
    DEALLOCATE TableCursor 

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

BEGIN TRAN

DECLARE @table_name VARCHAR（MAX）是什么

DECLARE table_cursor CURSOR LOCAL FOR
SELECT TABLE_NAME FROM INFORMATION_SCHEMA.TABLES

OPEN table_cursor

FETCH NEXT FROM table_cursor INTO @table_name

WHILE @@FETCH_STATUS = 0 

     BEGIN 

     PRINT 'ALTER INDEX ALL ON '+@table_name+' 

REBUILD WITH（FILLFACTOR = 100）”

 END 
     CLOSE table_cursor; 
    DEALLOCATE table_cursor; 

ROLLBACK TRAN
