Question

I have query

UPDATE  THD 
SET     RepostFlag = 'Y'
        ,RunListNoRetroPolicyPrepay = ?
        ,RetroObject = ?  
FROM    TranHead AS THD  
            JOIN (
                    SELECT  CustPolicyNo AS CustPolicyNo
                            ,MIN(PremPeriod) AS PremPeriod 
                    FROM    TranHead 
                    WHERE   RepostFlag = 'Y' 
                            AND PayoutTypeNo = ? 
                    GROUP BY CustPolicyNo
            ) AS THDToBeReposted  ON THD.CustPolicyNo = THDToBeReposted.CustPolicyNo 
WHERE   THD.RepostFlag = 'N' 
        AND THD.PremPeriod >  THDToBeReposted.PremPeriod 

fails in H2 with following message

Table “THD” not found;

I looked at http://www.h2database.com/html/grammar.html#table_expression to see if H2 supports selects in join. It appears it does. Maybe I am missing something when looking at the grammar, but it seems to me that the query should work in H2.

Anyone see what is wrong?

Thanks.

I don’t believe FROM is allowed in the UPDATE syntax.
