Problem IT44970 Status: Closed

RUNNING A QUERY WITH "SELECT ... FROM FINAL TABLE(INSERT ...);" RETURNS
DATA IN PRIMARY BUT NOT IN UPDATABLE SECONDARY

product:
INFORMIX SERVER / 5725A3900 / E10 -
Problem description:
The syntax "SELECT ... FROM final TABLE(INSERT...);" returns
data on a Primary server but not on an Updatable Secondary.

SELECT
id AS ID,
ip AS IP,
port AS Port,
protocol_id AS ProtocolID,
read_position_start AS ReadPositionStart,
read_position_amount AS ReadPositionAmount
FROM final TABLE(
INSERT INTO mytab
(ip, port, protocol_id,  read_position_start,
read_position_amount)
VALUES('10.0.0.211',3030,1,0,0));

On a Primary server it returns:

id                  1
ip                  10.0.0.211
port                3030
protocolid          1
readpositionstart   0
readpositionamount  0

2 row(s) retrieved.

Database closed.

But on an HDR Updatable Secondary it returns:

1 row(s) retrieved.

Comment


This syntax is not documented/supported on Informix Dynamic
Server.  Therefore, no change will be made to support it on a
secondary server.
