SQL constraint minvalue / maxvalue?

SQL Server syntax for the check constraint:

create table numbers (
    number int not null
        check(number >= 1234 and number <= 4523),
    ...
)

create table numbers (
    number int not null,
    check(number >= 1234 and number <= 4523),

)

create table numbers (
    number int not null,
    constraint number_range_check
        check(number >= 1234 and number <= 4523),
    ...
)

SQL Limit min and max value in database

Add a check constraint:

CREATE TABLE TBL_CD(
CDnr                int identity(1,1),
CDTitel             nvarchar(80) NOT NULL,
CDduur              int,
CDprijs             smallmoney,
check (CDprijs between 0 and 100),

oracle sql column value from .. to

You need to add a check constraint to your table. e.g:

ALTER TABLE your_table
ADD CONSTRAINT check_grade
  CHECK (grade between 1 and 6); 

Set a constraint for minimum int value

For server side validation, implement IValidatableObject on your entity. For client-side validation, if you are using MVC, add the data annotation to your view model. And to add a database constraint, add the check constraint by calling the Sql() method in a migration.
