修改MS SQL 2008 R2中所有表中主键的填充因子

Question

是否有任何工作方法来修改数据库中所有表的主键的填充因子参数？

Answer 1

此脚本查找所有主键,并为每个主键构建一个ALTER INDEX语句并执行它.

---- change this to your desired value ----
DECLARE @NewFillFactor smallint = 92
-------------------------------------------
DECLARE @TableName varchar(300), @IndexName varchar(300), @sql varchar(max)

DECLARE inds CURSOR FAST_FORWARD FOR
SELECT TABLE_NAME, CONSTRAINT_NAME
FROM INFORMATION_SCHEMA.TABLE_CONSTRAINTS
WHERE CONSTRAINT_TYPE='PRIMARY KEY'

OPEN inds
FETCH NEXT FROM inds INTO @TableName, @IndexName

WHILE @@FETCH_STATUS = 0
BEGIN
    SET @sql = 'ALTER INDEX [' + @IndexName + '] ON [dbo].[' + @TableName + '] REBUILD WITH ( FILLFACTOR = ' + cast(@NewFillFactor as varchar(3)) + ')'
    PRINT @sql
    EXEC(@sql)
    FETCH NEXT FROM inds INTO @TableName, @IndexName
END

CLOSE inds
DEALLOCATE inds

PRINT 'Done'
