How to set minimum value for a SQL Server column

Question

I am using SQL Server 2008 R2

I want to set a column minimum value

Column type is int

I want to set minimum value of 0

So if I update the column with -32 it should automatically set column value to 0

Answer 1

The simplest solution is to force the calling code to correct their data rather than magically alter it on insert. To do that, add a check constraint:

Alter Table MyTable
    Add Constraint CK_MyTable_Col Check ( MyCol >= 0 )
