sql-server - SQL；按合并列搜索

Question

我正在创建一个存储过程。我有两列，名字和姓氏。

我可以使用以下语句合并它们:

REPLACE(dbo.Employee.Forename, ' ', '') + ' ' + 
     REPLACE(dbo.Employee.Surname, ' ', '') AS EmployeeFullName

如果我想按 EmployeeFullName 进行搜索，我该怎么做？

WHERE EmployeeFullName = @Name

其中@name 是存储过程的参数输入。

CREATE PROCEDURE EmployeeSearch
    @Name VARCHAR(50)
AS
    SELECT 
        dbo.Employee.Number, 
        REPLACE(dbo.Employee.Forename, ' ', '') + ' ' + REPLACE(dbo.Employee.Surname, ' ', '') AS EmployeeFullName, 
        DateOfBirth
    FROM 
        dbo.Employee
    WHERE        
        EmployeeFullName = @Name

    RETURN
GO

Answer 1

您可以创建如下存储过程:

CREATE procedure EmployeeSearch 
@name varchar(50)
as
begin

    SELECT Number, EmployeeFullName from (
        SELECT dbo.Employee.Number, REPLACE(dbo.Employee.Forename, ' ', '') + ' ' + REPLACE(dbo.Employee.Surname, ' ', '') AS EmployeeFullName
        FROM yourtable
    ) AS T WHERE EmployeeFullName = @Name

end
