How is it possible to insert a NULL into an ORACLE TABLE when host variable has been initialized?
To achieve this goal, you have to use the indicator variables:
*Put a NULL value in a record using indicator variables
move 6 to V-KEY
move spaces to V-DATA
move -1 to IND-VAR
EXEC SQL INSERT INTO V_TABLE VALUES (:V-KEY, :V-DATA:IND-VAR)
When the value of the indicator variable is equal to -1, the value of the host variable is ignored and NULL will be used, instead.
All info related to the indicator variable are available at the isCOBOL documentation in the 'Language Reference Manual-> Embedded SQL-> Indicator Variables' chapter.
