Hi All,
I will change the CorrelId and the value needs to be the value of RootElement of the XML document (input message).
The data type of RootElement is CHAR.
So I need to CAST the RootElement to BLOB.
If it less than 24 bytes, I will add zeros before it.
The CorrelId is BLOB, so I CAST the RootElement as BLOB fist.
But I don't know how to add zero before it.
It said: Invalid or incompatible data types for '||' operator.
Here is my code:
| Code: |
DECLARE RootValueBlob BLOB CAST(Root_Element AS BLOB CCSID InputRoot.Properties.CodedCharSetId);
DECLARE LEN INT;
SET LEN = LENGTH(RootValueBlob);
WHILE (LEN < 24)
DO
SET RootValueBlob=RIGHT('0'||RootValueBlob,24);
SET LEN = LEN +1;
END WHILE; |
After '||', it cannot connect the BLOB data type.
So how should I do?
Thank you very much. |

Well your char is a hex representation of 24 bytes and needs 48 chars.
So why don't you use the char to append / prepend char '0' until the total is 48 chars and only then cast it to BLOB?
Your problem is because your are trying to concatenage a char with a blob.
You should be trying to concatenate a hex 00 with the blob or a char with the char.

Thank you for you reply,
When I add char'0' until the total is 48 chars, and CAST it to BLOB.
The BLOB return the '0000' are '3030'
What is the problem? |

You mean something like
| Code: |
SET insertstr = replicate('0', 48 -length(id));
result = overlay(id placing insertstr from 0 for 0); |
