|
|
Hi
In a file a variable pol-num is declared as 9(16). In DB2 table column is polno declared as decimal(16,0).
When I try to check pol-num in table with select statement I'm getting pol-num as undefined or unusual host variable.
select polno into :ws-pol-num from policy where polno = :pol-num
I declared ws-pol-num pic 9(16).
Where is data incompatibility? any help |

SRI123,
If the POLNO in DB2 table is defined as DECIMAL, then the COBOL equivalent of that is COMP-3. Check this link which explains the equivalent SQL and COBOL data types
Alternatively you can use DCLGEN to generate the table host variables so that you don't have worry about defining the equivalent data types. _________________ Kolusu

Thanks for reply Kolusu.
In input file field is declared as pic 9(16).
I'm moving this to host variable POLNO PIC S9(16)V USAGE COMP-3 and selecting the statement
select polno into :ws-pol-num from policy where polno = :POLNO
Now i"m getting sqlcode -206 for the table column polno
SQLCODE=-206
SQLSTATE=42703
TOKENS=POLNO
CSECT NAME=DSNXORSO
RDS CODE=-100 |

n DB2 the column is defined as decimal, in COBOL the host variable should be usage COMP-3.

NOTICE that you defined "ws-pol-num" but your select statement references ":pol-num" =====> not the same as you cobol variable !!
PS Never use variables defined in the FD / SD section of the code as HOST VARIABLES in a DB2 statement. The reason is that the address of the FD / SD fields changes after every file operation and DB2 only establishes the address of HOST VARIABLES once normally. _________________ Chuck Haatvedt
