Bug Type: Bug
Bug description:Column size is not reserved for all UNION
Description:
------------
When I concatenate two queries with UNION an there are static strings in
the queries, mysqli only reserves a big enough variable for the strings in
the first query.
If there are static strings in the other queries after the UNION, the
strings are just cut off.
Test script:
---------------
$stmt = $this->mysqli->prepare("SELECT 'read' AS Action FROM tbl1
UNION
SELECT CASE status WHEN 0 THEN 'request-received' WHEN 1 THEN 'confirmed'
WHEN 2 THEN 'x' END AS Action FROM tbl2");
$stmt->bind_result($action);
$stmt->execute();
while($stmt->fetch())
{
echo $action . " ";
}
Expected result:
----------------
expected output is: read request-received confirmed
Actual result:
--------------
actual output is: read request-recei confirmed
The "request-received" is cut off!
