I am hoping someone can shed light on this for me. We have a fairly simple
query that is pulling data from numeric fields and concatenating the field
contents into a single results column. The problem is the resulting data is
reported to be BLOB instead of the expected concatenated string....which in
turn is causing our application to complain about an unsupported data type
(our application is expecting a string value to be returned). It seems like
an error in MySQL to us.

If anyone is feeling adventurous, I can provide access to a data server to
see the actual data and play with the query.


this query returns BLOB's:

SELECT CONCAT(tblSystemType_1.strDescription, '/',
tblSystemType_2.strDescription, '/', tblSystemType_3.strDescription, '_',
tblSystemType_1.intSystemTypeID, '/',tblSystemType_2.intSystemTypeID,
'/',tblSystemType_3.intSystemTypeID) FROM tblSystemType AS tblSystemType_1,
tblSystemType AS tblSystemType_2, tblSystemType AS tblSystemType_3 INNER
JOIN tblLineItems ON tblSystemType_1.intSystemTypeID =
tblLineItems.intSystemTypeID1  AND tblSystemType_2.intSystemTypeID =
tblLineItems.intSystemTypeID2  AND tblSystemType_3.intSystemTypeID =
tblLineItems.intSystemTypeID3  WHERE (((tblLineItems.varProjectID)=1) AND
(tblLineItems.intLineItemTypeID = 5) AND booActive <> 0)  ORDER BY
tblSystemType_1.intSystemTypeID AND tblSystemType_2.intSystemTypeID AND
tblSystemType_3.intSystemTypeID


strangely enough, this one wroks as expected (has only 2 system types,
rather than 3...):

SELECT CONCAT(tblSystemType_1.strDescription, '/',
tblSystemType_2.strDescription, '_', tblSystemType_1.intSystemTypeID,
'/',tblSystemType_2.intSystemTypeID) FROM tblSystemType AS tblSystemType_1,
tblSystemType AS tblSystemType_2 INNER JOIN tblLineItems ON
tblSystemType_1.intSystemTypeID = tblLineItems.intSystemTypeID1  AND
tblSystemType_2.intSystemTypeID = tblLineItems.intSystemTypeID2  WHERE
(((tblLineItems.varProjectID)=4) AND (tblLineItems.intLineItemTypeID = 1)
AND booActive <> 0)  ORDER BY tblSystemType_1.intSystemTypeID AND
tblSystemType_2.intSystemTypeID


Thanks for any suggestions or answers anyone is kind enough to provide.
