Question

I’m working on creating a model data base design for a retail store. I’m trying to create a single procedure which will initialize the database schema.

What I’m trying to achieve is to create a new schema from inside the procedure. My code is as follows:

begin trans

create procedure Retail_Fill
as
    create schema Retail_Test;  
    go
    create table Retail_Test.customer(
        cust_id int,
        cust_name varchar(30),
        cust_phone int,
        cust_add varchar(50),
        constraint pk_customer primary key (cust_id)
    );

Here the create schema statement works fine by itself. But inside the procedure it gives an error:

Invaid Syntax!CREATE SCHEMA must be the only statement in the batch

I want to know if it is at all possible to achieve this. If yes then what am I doing wrong or where is the error?

Answer 1

CREATE SCHEMA has to be executed as a separate batch. Batches in SQL Server Management Studio is separated by GO. That is not the case in a stored procedure. You can do what you want by using EXECUTE for the statements that needs to be in a batch of its own like CREATE SCHEMA or CREATE PROCEDURE.

create procedure Retail_Fill
as
exec('create schema Retail_Test');

create table Retail_Test.customer(
    cust_id int,
    cust_name varchar(30),
    cust_phone int,
    cust_add varchar(50),
    constraint pk_customer primary key (cust_id)
);
