删除表：
DECLARE @Table NVARCHAR(30)
DECLARE tmpCur CURSOR FOR
SELECT name FROM sys.objects WHERE TYPE='U' AND name LIKE N'HSUPA%'
OPEN tmpCur
FETCH NEXT FROM tmpCur INTO @Table
WHILE @@FETCH_STATUS = 0
BEGIN
DECLARE @sql VARCHAR(100)
SELECT @sql = 'drop table ' + @Table
EXEC(@sql)
FETCH NEXT FROM tmpCur INTO @Table
END
CLOSE tmpCur
DEALLOCATE tmpCur
改表名：
declare @oldName varchar(30),
@newName varchar(30)
declare cursor_taname CURSOR FOR
SELECT name,upper(name) as newname FROM sysobjects where type='u'
OPEN cursor_taname
FETCH NEXT FROM cursor_taname INTO @oldname,@newName
WHILE @@FETCH_STATUS=0
BEGIN
SET @newName=(replace(@oldname,'rc_','tbl_'))
print(@oldname+', '+@newName)
EXEC sp_rename @oldname,@newName
FETCH NEXT FROM cursor_taname INTO @oldname,@newName
END
CLOSE cursor_taname
DEALLOCATE cursor_taname
