Hi,
-305 is Null Indicator is needed. The null value cannot be
assigned to output host variable. Because no Indicator
variable is specified. (to fetch or select operation
resulted in the retrieval of a null value to be inserted
into the output host vaariable)

-407 is An update or insert value is null. but the object
column name cannot contain null values.(the update or insert
value was null. But the object column was declared as not
nullin the table)
