Hi to all,

executing an INSERT INTO like this:

INSERT INTO "_Tests_Steps"
(
"New_Test_Step_Id",
"Test_Step_Id",
"Process_Test_Id",
"Step_Id",
"Sequence_Id",
"StepGroup_Id",
"Skip"
)
SELECT
nextval('"Tests_Steps_Test_Step_Id_seq"'),
"Test_Step_Id",
B."Process_Test_Id",
"Step_Id",
"Sequence_Id",
"StepGroup_Id",
A."Skip"
FROM "_Processes_Tests" B INNER JOIN "Tests_Steps" A
ON A."Process_Test_Id" = B."Process_Test_Id"
WHERE "Version_Id" = vers_id
ORDER BY "Test_Step_Id";
...............
where "_Tests_Steps" and "_Processes_Tests" are both temporary
tables, in the resulting "_Tests_Steps table records are not sorted in
the expected mode.
In other word, I need to extract records from "Tests_Steps" and then put
them in "_Tests_Steps" ordered exactly as they were inserted first time.
This because I need to duplicate this records, assigning them a new
serial value. This records are later binding to others records of
different tables.

The resulting recordset is the follow:

"New_Test_Step_Id", "Test_Step_Id", "Process_Test_Id", "Step_Id",
"Sequence_Id", "StepGroup_Id", "Skip"
2332; 2136;
2225; 958; 404;
363; f
2331; 2137;
2225; 959; 404;
363; f
2334; 2285;
2225; 960; 404;
363; f
2333; 2286;
2225; 961; 404;
363; f

Apparently, new records are not inserted in the table according to the
order selected by "Test_Step_Id" field;

Any suggest??

Thanks in advance
