打印出来的SQL代码:
SELECT column_name, data_type, column_default, is_nullable FROM information_schema.tables AS t JOIN information_schema.columns AS c ON t.table_catalog = c.table_catalog AND t.table_schema = c.table_schema AND t.table_name = c.table_name WHERE t.table_name = 'dbo.news'
!!!哪来的select？update呢。同样的代码连接mysql时却是工作正常，sql里面是update,求解啊！是不是这文件有问题……
