Sql server 2008 如果在存储过程中找不到数据，则跳过字段

问题在这里。我正在创建一个存储过程，我想确定其中一列是否没有数据，然后它将跳过该行

示例：表名：Employee

Employee No | Employee Name | Card No | Salary 
1           | test 1        | 123     | 
2           | Simon         |         |  2000        
3           |               | 456     |  4000
4           | test3         | 342     |  5000
5           |               | null    |  3000

它将只读取包含完整数据的行，这些数据是

employeeno=4

，

name=test3

，

card no=3432

和

salary=5000

，使用过滤器 e、 g

---

Use

不为空

和

LEN（）

试试这个：

SELECT *
FROM Employee
WHERE (EmployeeNo IS NOT NULL OR LEN(EmployeeNo) > 0) AND
      (EmployeeName IS NOT NULL OR LEN(EmployeeName) > 0) AND
      (CardNo IS NOT NULL OR LEN(CardNo) > 0) AND
      (Salary IS NOT NULL OR LEN(Salary) > 0)

可以使用isnull（）如下所示：

它将同时检查null和“”的大小写。

thx以进行编辑。。如何做得像桌子，那么漂亮

SELECT *
FROM Employee
WHERE (EmployeeNo IS NOT NULL OR LEN(EmployeeNo) > 0) AND
      (EmployeeName IS NOT NULL OR LEN(EmployeeName) > 0) AND
      (CardNo IS NOT NULL OR LEN(CardNo) > 0) AND
      (Salary IS NOT NULL OR LEN(Salary) > 0)

SELECT *
  FROM Employee
 WHERE 
   ISNULL(EmployeeNo,'') != ''
   AND ISNULL(EmployeeName,'') != ''
   AND ISNULL(CardNo, '') != ''
   AND ISNULL(Salary, '') != ''
