工作T-SQL备忘

作为一个"浸淫" Oracle 数据库很久的人来说, 突然转入 T-SQL, 也就是 MSSQL , 工作中经常用的查询和 MSMS 使用备忘如下 :

--1. 切换对应的库连接
USE CYBPMCOSTDB1041_Dev
--2. 查看存储过程内容
SP_HELPTEXT 'V0DataDict'
--3. 查看表列内容
sp_columns	'A1Org'
--4. 查看数据库表描述, 行列转换过, 可以看到包括备注之类(自定义视图, 后面附视图内容)
SELECT *FROM dbo.V0DataDict WHERE name='A1Org'
--5.
--执行带输出参数的存储过程
DECLARE @p_RecTotal int
EXEC PM1SpecialEqptRegisterPage
@p_OrgID = 'ED6989D2-B7CB-478B-9E37-D0C15D720D6A',
@p_ManageCode = '',
@p_FilterStr='',
@p_PageIndex = 0,
@p_PageSize= 25,
@p_OrderField = 'BizDate',
@p_OrderType = 1,
@p_IsLargeEqpt = -1,
@p_RecTotal = @p_RecTotal OUT
SELECT @p_RecTotal

• 附上对应视图的内容

• 另外发现很多人或者我这种半路开始使用MSSQL的经常误区. 如图所示:
  • 一般来说刚打开自动登陆的就是对象浏览器. 至于当前界面查询使用哪个链接 是分开的. 不然一直在对象浏览器里面切来切去, 是跟当前查询没有任何关系的.
