Stored procedures 为存储过程编写脚本的请求在进程查询中返回值

编写计分过程脚本的请求，返回以下内容：

请求

当传递null时，返回所有

和字段可以搜索

组合可以搜索

• “当传递null时，返回all”=>

  其中col=ISNULL（@argument，col）

• 其余条件应该可以工作，但初始查询的性能不是最好的（multiple join和multiple OR in where子句）可能会导致全表扫描

• 您还可以将完全限定的名称（如

  [dbo].Customer）别名为c

  ，然后使用

  dbo.Customer.lasname

  简单地命名为

  c.lasname

• 可能您在（相同的表和列）

  [dbo]上联接时出错。dbo.Cases.CustomerId=dbo.Cases.CustomerId上的客户
