在SQL server中查找特定类别的列
<div id="cnblogs_post_body">最近在做个project，需要对特定类别的列进行一些操作，为了避免遗漏，所以弄了这个script，比较方便检查数据库内同一类别的所有列，记录一下，备用，例子里面是来查所有nvarchar的列.<div class="csharpcode"> 1:SELECT a.name, o.name AS TableName, o.type, a.id, o.object_id, o.schema_id 2:FROM sys.syscolumns AS a INNER JOIN sys.systypes AS b ON a.xtype = b.xtype 3:AND b.name = 'nvarchar' 4: INNER JOIN 5:sys.objects AS o ON a.id = o.object_id 6:WHERE (o.type = 'u') 7:AND (o.schema_id = 1)
