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.

If a column contains nulls and you dont include a null
indicator variable in the program, the program receives a
-305 SQLCODE.
Even if no columns allow for nulls, it may be necessary to
use the null indicator to avoid a -305 SQLCODE. For eg, if
AVG(SAL) is computed and ther eare no employees in the
department, the result is null and a null indicator must be
ccoded on the SQL statement to avoid -305.
EXEC SQL SELECT SNAME
INTO :SNAME:SNAME-INDNULL
FROM S
WHERE SN = :SN-IN
END-EXEC
If SNAME has a value, SNAME-INDNULL contains 0.
If SNAME is NULL, SNAME-INDNULL contains -2.
Similarly, Inserting a NULL also required special handling.
If you are not providing a value for SNAME, a -1 can be
moved to the null indicator associated with the SNAME
column:
MOVE -1 to SNAME-INDNULL
EXEC SQL INSERT INTO S
(SN,SNAME,STATUS,CITY) VALUE
(:SN,:SNAME:SNAME-INDNULL,:STATUS,:CITY)
END-EXEC

If you are moving NULL to host variable, -305 error will
get.
check in your db2 table whether NULL values are present or
not.

if the table column is defined as NOT NULL (with no
default) and if we try to insert a null value we get that
we get a different SQLCODE -407

Answer / yogesh
- 407 : Column in the table is defined as "NOT NULL", but
an INSERT or UPDATE is done to make the column as 'NULL'
-305 : Trying to FETCH or SELECT a null value from the
column of a table to a output host variable, which doesn't
have a null indicator declared for the host variable.

Answer / vikram and mangesh
The null value is the concept of DB2 and your application
program does not understand the null concept, so to handle
the null value in our application program we use null
indicator.
Null indicator will have following values(depending upon
what values comes from DB2).
0 means the column is not null and any actual value stored
in the column is valid.
-1 means column is set to null.
-2 means column was set to null as the result of a data
conversion error.
in above scenarion if your table contains nullable columns
(means the column can have null values) and in aplication
program you dont mentioned the null indicator,you will get
sql code -305.
For a NOT NULL column there is no need of null indicator as
there cannot be null at any point of time and if you dont
give any value then you will get SQL code -407.
