Question

我有两张桌子

第一个表格为CUSTOMERS，其中包含CustomerId, CustomerName列
第二个表格为LICENSES，其中包含LicenseId, Customer列

第二个表格中的Customer列是第一个表格中的CustomerId

我想创建一个将值插入表2的存储过程

Insert into Licenses (Customer)
Values(CustomerId)

如何从其他表中获取此数据？

提前感谢您提供任何帮助

Answer 1

CREATE PROCEDURE uspInsertToTable
    @CustomerID INT OUTPUT,
    @CustomerName VARCHAR(50),
    @LicenseID INT,

AS
BEGIN
    BEGIN TRY
        BEGIN TRANSACTION;

            INSERT INTO CUSTOMERS
            VALUES (@CustomerName);
            SET @CustomerID=SCOPE_IDENTITY();

            INSERT INTO LICENSES
            VALUES (@LicenseID, @CustomerID)

        COMMIT TRANSACTION;

    END TRY
    BEGIN CATCH

        IF @@TRANCOUNT > 0
        BEGIN
            ROLLBACK TRANSACTION;
        END

    END CATCH;
END;
 ];

如果CustomerID是身份，我希望它能起作用...... :)

Answer 2

这对我来说只是一个语法问题 - 我想你想要的是

INSERT INTO Licenses (Customer) SELECT CustomerId FROM customers where ...

Answer 3

如果你正在使用SQL Server而你的PK使用identity(1,1)进行自相关，请执行以下操作：

CREATE PROC Register @CustomerName varchar(25)
AS BEGIN
   INSERT INTO CUSTOMERS (Customer) VALUES (@CustomerName)
   INSERT INTO LICENSES (SELECT MAX(CustomerId) FROM CUSTOMERS)
END

但如果你不想使用identity (1,1)，请执行以下操作：

CREATE PROC Register @CustomerName varchar(25)
    AS BEGIN
       DECLARE @idc int = SELECT MAX(CustomerId) FROM CUSTOMERS;
       DECLARE @idl int = SELECT MAX(LicenseId) FROM LICENSES ;
       INSERT INTO CUSTOMERS (CustomerId, CustomerName) VALUES (@idc,@CustomerName)
       INSERT INTO LICENSES (LicenseId, Customer) VALUES (@idl,@idc)--I guess your field Customer is the foreign key
    END
