Question

CREATE TABLE DEPARTMENT(
DEPARTMENT_NAME VARCHAR(25) NOT NULL PRIMARY KEY ,
BUDGET_CODE INT NOT NULL,
OFFICE_NUM INT NOT NULL, 
PHONE NUMERIC NOT NULL ,
);

I have this table that I am creating but i want to change budget code and office number in varchar instead of int. Is there a way to do this. this table is linked to other tables with foreign key. So i can’t drop it and create a new one.

Answer 1

Try this

ALTER TABLE dbo.DEPARTMENT
ALTER COLUMN BUDGET_CODE VARCHAR(100)
ALTER COLUMN OFFICE_NUM VARCHAR(100)
