In MySQL it is possible to do something like this:

RIGHT(CAST(intvalue AS char), 7)

If the integer value is greater than 9,999,999, you will lose the highest order digits, of course.

Depends on DBMS Oracle: TO_CHAR() , SQL Server str(). These are formating functions. For plain type conversion you can use cast
