There are two ways.
One, construct the BLOB string using binary values.
Two, construct the blob string using character values and then cast it as a blob string - this requires the correct encoding (at least).
Which one are you trying to use? |
I tried the second but it didn't work, I used the target server ccsid and encoding as well.
I'll try the first option, hopefully it works |

If you notice, the values he provided are the decimal values (signed) of the equivalent byte for each of the bytes in the array.
At this point I would suggest some Java procedure to parse the string on token ',' and create the byte array, byte by byte. He can then return the array as blob.

OK - I have some important new information to contribute to this discussion. The only way to treat binary data as raw bytes is to use the CWF physical format. That's not too bad, because the model is simple, and CWF can do the length-reference trick just as easily as TDS. The important point is that ( contrary to what I said before ) TDS cannot handle a string of un-encoded raw bytes.
mgm: Apologies for any confusion / wasted time. |
