‘CREATE PROCEDURE’ must be the only statement in the batch (Erro)

The error is self-explanatory – you cannot issue a CREATE PROCEDURE statement unless it’s the only statement in the batch.

In SSMS the GO keyword splits the statement into separate batches, so you need to add one after the statement before the CREATE PROCEDURE:

create table josecustomer(
name varchar(50),
address varchar(300),
ssnid int,
balance bigint,
accountnumber bigint
)

insert into josecustomer values('Aman','Canada',10000,5000,100000000)
insert into josecustomer values('Shubham','USA',10001,6000,200000000)
insert into josecustomer values('Himanshu','Australia',10002,2000,300000000)
insert into josecustomer values('Jose','India',10003,3000,400000000)
insert into josecustomer values('Albert','Brazil',10004,4000,500000000)
insert into josecustomer values('Peterson','Germany',10005,7000,600000000)
insert into josecustomer values('Adam','Honkong',10006,8000,700000000)
insert into josecustomer values('William','Paris',10007,9000,800000000)
