在这种情况下,我建议在 SQL Server 中使用 2 个 sp:
sp_MSforeachtable
sp_MSforeachdb
更多信息,请阅读here中的文章。
希望对您有所帮助。
exec @RETURN_VALUE=sp_MSforeachtable @command1, @replacechar, @command2,
@command3, @whereand, @precommand, @postcommand
exec @RETURN_VALUE = sp_MSforeachdb @command1, @replacechar,
@command2, @command3, @precommand, @postcommand
完整的脚本:
declare @DatabaseName varchar(max), @DatabaseCharParam nchar(1)
declare @TableSchema varchar(max)
declare @TableName varchar(max), @TableCharParam nchar(1)
set @DatabaseName='DATABASENAME'; set @DatabaseCharParam='?'
set @TableSchema='dbo'
set @TableName='TABLENAME'; set @TableCharParam='$'
-- Exemple Script to execute in each table in each database
-- Create first part of a statement to update all columns that have type varchar
DECLARE @sSql VARCHAR(MAX)
set @sSql=''
SELECT @sSql = isnull(@sSql,'') + COLUMN_NAME + ' = LOWER(RTRIM(' + COLUMN_NAME + ')),'
FROM INFORMATION_SCHEMA.COLUMNS
WHERE DATA_TYPE = 'varchar'
AND TABLE_CATALOG = @DatabaseName
AND TABLE_SCHEMA = @TableSchema
AND TABLE_NAME = @TableName
declare @EachTablecmd1 varchar(2000)
--Prepare @EachTablecmd1 the script to execution in each table using sp_MSforeachtable (ATENTION: @Command1 are limited to varchar(2000) )
--in sp_MSforeachtable @TableCharParam will be subtituted with owner i.e:[dbo].[TABLENAME]
set @sSql='update '+@TableCharParam+' set '+ left(@sSql,LEN(@sSql)-1)
set @EachTablecmd1='if '''''+ @TableCharParam +'''''=''''['+@TableSchema+'].['+@TableName+']'''' '+@sSql
--i.e.: if 'table1'='table1' update table1 set column1=LOWER(RTRIM(column1)),....
-- the @sSql for each table in a database
set @sSql ='exec sp_MSforeachtable @command1='''+@EachTablecmd1+''' ,@replacechar='''+@TableCharParam+''''
declare @EachBDcmd1 varchar(2000)
--Prepare the execution to each database using sp_MSforeachdb (ATENTION: @Command1 are limited to varchar(2000) )
set @EachBDcmd1='if '''+@DatabaseCharParam+'''='''+@DatabaseName+''' '+ @sSql
--print @EachBDcmd1
exec sp_MSforeachdb @command1=@EachBDcmd1,@replacechar=@DatabaseCharParam
