'('.期待ID)附近的语法不正确

Question

我已经查看了其他几个此类问题,但没有找到一个可以帮我解决这个问题的问题.我想要做的是:我想为所有员工创建一个表,以便分配一个EmployeeID将在其他几个表中使用的表.该表和其他表工作正常.当我尝试创建一个新表时,我的问题就出现了,EmployeeType因此我可以仅根据特定类型的员工提供信息.在SELECT所有三个表的语句中,我收到此错误:

'('.期待ID)附近的语法不正确.

我用Google搜索并搜索了如何解决它,但我尝试过的任何工作都没有.我错过了什么？

CREATE TABLE Employees

    EmployeeID      int             NOT NULL    PRIMARY KEY IDENTITY,

CREATE TABLE Volunteers AS

Answer 1

SQL Server没有CREATE TABLE .... AS (SELECT ...功能.这只是无效的T-SQL语法 - 因此错误.

如果要从a 创建新表(现在还不存在!)SELECT,则需要使用以下语法:

SELECT
    EmployeeID AS ReviewerID,
    EmpFirstName,
    EmpLastName,
    EmpAddress,
    EmpCity,
    EmpState,
    EmpZipCode,
    EmpPhone,
    EmpJobTitle
INTO 
    dbo.Volunteers    
FROM    
    dbo.Employees
WHERE
    EmployeeType = 'Volunteer';

这仅适用于新表 - dbo.Volunteers- 尚不存在的情况.

如果需要将行插入现有表中,则需要使用以下语法:

INSERT INTO dbo.Volunteers (list-of-columns)
    SELECT (list-of-columns)
    FROM dbo.Employees
    WHERE EmployeeType = 'Volunteer';
