Question

问题是我有一个表Employee，其中有一个字段employeeAddress（varchar（200）），我在SQL Server中创建一个View EmployeeView，我想将它更改为employeeAddress（varchar（50）），意思是我想只显示employeeAddress列的50个字符，然后再与'...'连接。

例如： - 新德里（假设它是100个字符）我想将其更改为EmployeeView

NewDel（假设它是50个字符）那么它应该是“NewDel ...”

Answer 1

你可以试试这个

<div prefix="true">$</div>

Answer 2

现有的大多数答案似乎都缺少对条件省略号的需求：

CREATE VIEW dbo.EmployeeView
WITH SCHEMABINDING
AS
    SELECT
        /* Other Columns */
        CASE
          WHEN LEN(EmployeeAddress) > 50
            THEN SUBSTRING(EmployeeAddress,1,50) + '...'
          ELSE EmployeeAddress
        END as EmployeeAddress
    FROM
        dbo.Employee
