hi ,
I had a table column whose DCL GEN IS defined as
AMOUNT PIC S9(7)V9(2)
Now requirement is I am getting an input feed in file as
WS-DOLLAR PIC9(4) value 356
WS-CENT PIC9(2) value 10
.
I need to concatenate the above two variables and insert into table , so that my table has data like 356.10 .
I am doing using a group variable to club the value and then passing to DCLGEN variable .At the time of imsertion its showing -310 error code .
I am using below logic
01 ws-net amt
05 ws-dollar pic 9(4)
05 ws-cent pic 9)2)
Before insertion , I am using this
Move ws-net-amt to AMOUNT(DCL GEN VARIABLR)
And using this value to insert , but its throwing -310 SQL ERROR , PLEASE GUIDE[/b] |

| That you're getting SQLCODE -310 suggests that you're not telling the whole truth, inadvertantly or otherwise. Read about SQLCODE -310 here. Re-read the "Programmer Response" as many times as necessary, until you understand what it means. |

The description of SQLCODE -310:
| Quote: |
-310
DECIMAL HOST VARIABLE OR PARAMETER number CONTAINS NON-DECIMAL DATA
Explanation
DB2® received nondecimal data from either an application (in the form of a host variable), function or a stored procedure (in the form of a parameter that was passed to or from function or a stored procedure). number Identifies either the host variable number (if the message is issued as a result of a FETCH, INSERT, UPDATE, MERGE, DELETE, SELECT, VALUES INTO, or SET assignment statement), or the parameter number (if the message is issued as the result of the invocation of a function, or a CALL statement).
System action
The statement cannot be processed.
Programmer response
Correct the application program or stored procedure. Ensure that all decimal variables or parameters contain valid System/370 packed decimal numbers. |
(Emphasis added.)
Now, how do you define a packed decimal variable in COBOL? By specifying USAGE of COMP-3. Do you tell us that AMOUNT is defined as COMP-3? No; therefore I say that you are not being entirely truthful.
Now, review the rules for group moves in COBOL. Do you think, even if AMOUNT were defined as COMP-3, that it would end up containing valid packed decimal data? |

Those rules are
| Quote: |
A group move is any move in which an alphanumeric group item is a sending item or a receiving item, or both.
The group moves are:
•A move to an alphanumeric group item from one of the following items:
◦any elementary data item that is valid as a sending item in the MOVE statement
◦a national group item
◦a literal
◦a figurative constant
•A move from an alphanumeric group item to the following items:
◦any elementary data item that is valid as a receiving item in the MOVE statement
◦a national group item
◦an alphanumeric group item
A group move is treated as though it were an alphanumeric-to-alphanumeric elementary move, except that there is no conversion of data from one form of internal representation to another. In a group move, the receiving area is filled without consideration for the individual elementary items contained within either the sending area or the receiving area, except as noted in the OCCURS clause. |
(Emphasis again added.)
Now WS-DOLLAR contains 356 and WS-CENT contains 10. So, what will WS-NET-AMT contain? X'F0F3F5F6F1F0', not so? When you move WS-NET-AMT, a group item, to WS-AMOUNT, the rules state that it will be as if WS-NET-AMT were defined as X(6), and WS-AMOUNT were defined PIC X(4), not so? So, WS-AMOUNT will contain X'F0F3F5F6'; is that a valid packed decimal number?
Define WS-CENT as PIC 99V99, and COMPUTE WS-AMOUNT = WS-DOLLAR + (WS-CENT / 100). |

move ws-dollar to amount.
add ws-cent/100 to amount
or
compute amount = ws-dollar + ws-cent/100 end-compute
and you can preface the compute with an IF
IF ws-dollar numeric and ws-cent numeric
Then compute.
else
move zero (or all 9's as an error indicator) to amount
end-if
that way you don't have non-numerics in your host-variable
and don't blow up the compute. |
