Hi mkiranmai,
1.Host Variables are nothing but the collecting working storage collections of the data fetched from the tables in database.We use DCLGEN for Host Variable Language specific data type defintions of the database fields.
2.Null Indicator Variables are there to handle situation where we get some null data instead of data if such case how to handle is done thru this by using the value of the Null Indiacor values 0.-1.-2.
Tell me What else you want on this.
Hope this would help. |

Hi,

| Code: |
EXEC SQL
SELECT EMPID,EFNAME,ELNAME,EMPDOB,EMPSAL,EMPDEPT
INTO :DCLEMPANJ
FROM EMPANJ
WHERE EMPID = 'A0001'
END-EXEC. |
| Code: |
01 DCLEMPANJ.
10 EMPID PIC X(5).
10 EFNAME PIC X(15).
10 ELNAME PIC X(15).
10 EMPDOB PIC X(10).
