Hello Guys,
i am using following when i set MQMD header in ESQL..
SET OutputRoot.MQMD.CorrelId = CAST((InputRoot.XML.ReservationFindWindowsNegativeAck.MessageId) AS BLOB CCSID 437);
i am getting length did not match exception,
Length of parser field name 'CorrelId' was '10'. It should be '24'.
1) how do i convert length in ESQL?
also at recieving end, there's a C program which now looks for a 10 char. string in correllationId when it performs get.
2) how do i convert a string in C (correlID) to a BLOB and also get the correlID length right?
Thanks In Advance |

You can't cast the CorrelID (or the MessageID) using a CCSID. These fields are BYTE fields, and as such, do NOT convert to characters.
Cheers,

if the messageid you want to convert is 48 chars which ontain the msgid (in hex form), just to
MQMD.MsgId = cast(messageid as blob);
if you converted them into chars, and it contains 24 chars, then you can do
MQMD.MsgId = cast(messageid as blob ccsid 850)
ccsid 850 can help you convert from blob to char and in reverse. |

Waugh,
You need to manually append rest of the CHAR to your CorrelID. Let's say your input field InputRoot.XML.ReservationFindWindowsNegativeAck.MessageId always have 10 char string, then you can use code similar to following to create 24 Byte CorrelID.
| Code: |
DECLARE CORLID BLOB;
SET CORLID = CAST (InputRoot.XML.ReservationFindWindowsNegativeAck.MessageId AS BLOB CCSID InputRoot.MQMD.CodedCharSetId);
SET OutputRoot.MQMD.CorrelId = CORLID || X'0000000000000000000000000000';
|
Depending your your requirement you can change the padding HEX to X'40' to get SPACES.
