Thanks to answer topic previous!!!!
I use this script to update one table
MERGE INTO EIS.CLI_HISTORY TXN
USING EIS.CLI_MAPING CLI
ON TXN.CLIENTID = CLI.CLIENTID
WHEN MATCHED AND
CLI.STATUSID = 3
AND CLI.CLIENTID != CLI.MAPPEDCLIENTID AND
CLI.CLIENTID = 24180 THEN
UPDATE
SET TXN.ISMERGED = 2,
TIMEACTUAL = CURRENT TIMESTAMP,
TXN.CLIENTID = CLI.MAPPEDCLIENTID;
But show problems of duplicate and the problem is with of row
TIMEACTUAL, because I don't put this row and the update was successful.
How I can update one row with TIMESTAMP but that is different. For
example
TimeActual 2005-12-09-09.31.05
TimeActual 2005-12-09-09.31.05
But I need that is diferent like this
TimeActual 2005-12-09-09.31.05
TimeActual 2005-12-09-09.31.06
Thanks to all !!!
