Before going to the solution, here is the explanation of a
null indicator.
In DB2, a NULL is stored using a special one-byte null
indicator which is attached to every NULLABLE column. If
the column is defined as NULL, then the indicator field is
used to record this. The indicator variable is transparent
to an end user, but must be provided for when programming
in a host language.
A positive value or a value of 0 means the column is not
null and any actual value stored in the column is valid. A
negative value indicates that the column is set to null. If
the value is -2 then the column was set to null as the
result of a data conversion error. The default is null.
There are two reasons for getting -305.
1) As said in the first answer if the table column is
defined as NOT NULL (with no default) and if we try to
insert a null value we get that.
- This should be resolved by making sure the inserted
value is not null. Null indicator cannot be used here since
the column is defined as NOT NULL.
2) A table column is defined as NULL:
The host variable has a not null value. The Null
indicator is not set in the host program, so the null
indicator is defaulted to a negative value.
- This should be resolved by using a null indicator in
the host program and moving the relevant value to the null
indicator.

SET is the ANSI standard for variable assignment, SELECT is not. SET can only assign one variable at a time, SELECT can make multiple assignments at once. If assigning from a query, SET can only assign a scalar value. If the query returns multiple values/rows then SET will raise an error. SELECT will assign one of the values to the variable and hide the fact that multiple values were returned (so you'd likely never know why something was going wrong elsewhere - have fun troubleshooting that one) When assigning from a query if there is no value returned then SET will assign NULL, where SELECT will not make the assignment at all (so the variable will not be changed from it's previous value) As far as speed differences - there are no direct differences between SET and SELECT. However SELECT's ability to make multiple assignments in one shot does give it a slight speed advantage over SET.
