sql 指删除表，改表名，改字段名

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
