如何在SQL Server的相关表中插入一个寄存器

Question

I have this table

Usuario

• id_usuario (FK)
• User
• Password
• FristName
• Lastname
• E-mail
• Photo_avatar

And I have this other table:

Imagenes

• id_imagen (FK)
• id_usuario
• Picture
• Picture_name

The relation:

Usuario.id_usuario = Imagenes.id_usuario

And I try to insert a picture into pictures but I need to take the id_usuario from Usuario

This is for a login system, and when I try to insert a picture, I have to do a query inserting the id_usuario . I want to write code that will automatically recognize the id for the moment when I insert the picture in Imagenes .

How can I do this?

Answer 1

You would use scope_identity() to get the identity value generated by the previous insert statement. So something like:

    declare @id_usuario int

    insert into Usuario 
    ([User], [Password], FristName, Lastname, [EMail], Photo_avatar)
    values (@User, @Password, @FristName, @Lastname, @EMail, @Photo_avatar)

    set @id_usuario = SCOPE_IDENTITY()

    insert into Imagenes
    (id_usuario, Picture, Picture_name)
    values (@id_usuario, @Picture, @Picture_name)
