What is check constraint?

Answer Posted / rajeev

The CHECK constraint is used to limit the value range that
can be placed in a column.

If you define a CHECK constraint on a single column it
allows only certain values for this column.

If you define a CHECK constraint on a table it can limit the
values in certain columns based on values in other columns
in the row.
