I am trying to use two DCLGEN's in the same program where two of the variables used is ambigous, ie; they are used in both the dclgen's. how to fix this issue?
Ex: The variable STL-CODE is used in both the DCLGEN's |

Not a problem and you can use it even when the names are same.

Have both the dclgen's INCLUDEd in the program and when it comes to differentiate the variables code as shown below
Say if the field X is in DCLGEN Y and Z
| Code: |
| MOVE X OF Y TO X OF Z |

Hi Aaru,
The code is as follows
EXEC SQL
INSERT INTO MTW.STK_MRKT_DTL(
STK_CODE,
DMAT_ACCT,
DMAT_ACCT_NAME,
DMAT_ACCT_ADDR,
STK_BUY_PRC,
STK_SELL_PRC,
TOT_STK_BOUGHT,
TOT_STK_SOLD,
STOP_LOSS_PRC,
STK_HLD_FROM,
LST_TXN_DATE,
CRT_USER_ID,
CRT_TMSTMP)
VALUES (
:STK-CODE,
:DMAT-ACCT,
:DMAT-ACCT-NAME,
:DMAT-ACCT-ADDR,
:STK-BUY-PRC,
:STK-SELL-PRC,
:TOT-STK-BOUGHT,
:TOT-STK-SOLD,
:STOP-LOSS-PRC,
:STK-HLD-FROM,
:LST-TXN-DATE,
CURRENT SQLID,
CURRENT TIMESTAMP)
END-EXEC
EXEC SQL
INSERT INTO MTW.STK_MRKT_HDR(
STK_CODE,
COMP_NAME,
COMP_ADDR,
CURR_STK_PRC,
CURR_YR_LOW,
CURR_YR_HIGH,
TOT_PUB_STK,
CRT_USER_ID,
CRT_TMSTMP )
VALUES (
:STK-CODE,
:COMP-NAME,
:COMP-ADDR,
:CURR-STK-PRC,
:CURR-YR-LOW,
:CURR-YR-HIGH,
:TOT-PUB-STK,
CURRENT SQLID,
CURRENT TIMESTAMP)
END-EXEC
where STK-CODE appears in both of the INSERT's. How to fix this issue as the compilation throws the following error:
DSNH314I E DSNHSMUD LINE 246 COL 0 REFERENCE TO HOST VARIABLE STK-CODE IS AMBIGUOUS
DSNH314I E DSNHSMUD LINE 300 COL 0 REFERENCE TO HOST VARIABLE STK-CODE IS AMBIGUOUS
I even tried like STK-CODE OF STK-MRKT-HDR and STK-MRKT-HDR.STK-CODE but both went in vain. |

reference qualification in COBOL is via the 'IN' or 'OF' keyword.
the format for qualifying columns in db2 is a little different.
it is either qualifier.column_name
or column_name.qualifier
i don't remember,
either refer to the documentation or try both ways and see which works |

an amendment to the previous post.
it is host variable and not column that is qualified. |

acrajesh,
This is how it should be done when the same field is there in 2 DCLGEN's.
Say the DCLGEN's are Y and Z
In the DCLGEN you would have 2 things
- DECLARE TABLE
- COBOL declaration for the TABLE
In the cobol declaration of the table make sure that the 01 level has the DCLGEN name.
| Code: |
01 X.
10 field one pic x(10)
10 field two pic x(20)
|
In the DCLGEN Y have it as
| Code: |
01 Y.
10 field one pic x(10)
|
then in the query use as shown below
| Code: |
EXEC SQL
INSERT
INTO TABLE
....
....
VALUES(FIELD EIGHT
,:X.FIELD ONE)
END-EXEC |
Similarly in the next query use it with the prefix Y.
Hope this helps |

acrajesh,
Which part of the code do you think is not working? Did you try ? |

If nothing is working and standards permit , U may try this (not tested)
Move STK-CODE of STK-MRKT-DTL to WS-CODE-DTL
Move STK-CODE of STK-MRKT-HDR to WS-CODE-HDR
Make sure the data types exactly match and use these these variables in your SQl insert query.
Hope This helps. |
