根据sysobjects 文档 https://msdn.microsoft.com/en-us/library/ms177596.aspx, sysobjects.xtype
可以是以下对象类型之一:
| xtype | Description |
|-------|---------------------------------------|
| AF | Aggregate function (CLR) |
| C | CHECK constraint |
| D | Default or DEFAULT constraint |
| F | FOREIGN KEY constraint |
| L | Log |
| FN | Scalar function |
| FS | Assembly (CLR) scalar-function |
| FT | Assembly (CLR) table-valued function |
| IF | In-lined table-function |
| IT | Internal table |
| P | Stored procedure |
| PC | Assembly (CLR) stored-procedure |
| PK | PRIMARY KEY constraint (type is K) |
| RF | Replication filter stored procedure |
| S | System table |
| SN | Synonym |
| SQ | Service queue |
| TA | Assembly (CLR) DML trigger |
| TF | Table function |
| TR | SQL DML Trigger |
| TT | Table type |
| U | User table |
| UQ | UNIQUE constraint (type is K) |
| V | View |
| X | Extended stored procedure |
我可以把它们放入CASE
声明,但是有没有一个表我可以加入来查找xtype
描述?我知道systypes
不是那张桌子吗我的意思是,我只是记住了其中的很多内容,但是我正在对数据库进行一些研究,这对我来说很陌生(即我对此不太了解),所以我想构建将该描述放入此查询中,无需CASE
陈述:
select object_name(c.id), c.name, [length], o.xtype from syscolumns c
join sysobjects o on o.id = c.id
where c.name like '%job%code%'
Update
下面是 SQLMenace 回答后的最终结果。我觉得有必要放在这里,因为它不仅仅是一个简单的前进join
.
select object_name(c.id), c.name, t.name, c.[length], o.xtype, x.name from syscolumns c
join sysobjects o on o.id = c.id
join systypes t on t.xtype = c.xtype
join master..spt_values x on x.name like '%' + o.xtype + '%' and x.type = 'O9T'
where c.name like '%job%code%'
order by c.xtype
