Oracle获得列名，列类型，列类型长度，scale，prec等数据类型
select column_name,data_type ,data_length,data_precision,data_scale from user_tab_columns where table_name=’TableName’
SQLserver获得所有表名
Select Name FROM SysObjects Where XType=’U’
Oracle获取所有表名
select tname from tab where tabtype=’TABLE’
获得表中主键的列，列类型，列类型长度
select a.name as colname, b.name as typename,a.length as length,a.scale as scale,a.prec as prec from syscolumns a,systypes b ,sysobjects c , INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE d where a.xusertype=b.xusertype and a.id=c.id and c.name =’TableName’ and b.name’DATE’ and a.name =d.COLUMN_NAME and d.CONSTRAINT_NAME like ‘PK_%’
