clause; columns not explicitly modified retain their previous values.
This option takes a list of one or more partitions or subpartitions (or both).
Only the partitions (or subpartitions) listed are checked for matches, and a row that is not in any of these partitions or subpartitions is not updated, whether it satisfies the clause, are flagged as unsafe for statement-based replication.
A "Join" can be recognized in a SQL SELECT statement if it has more than one table after the FROM keyword.If it does, then only one of the join rows will be used to update the target row, but which one will be used is not readily predictable.Because of this indeterminacy, referencing other tables only within sub-selects is safer, though often harder to read and slower than using a join.forinstance select from a join b on = In resultset I would like to manualy correct 'text' field. Doh I see no reason for it as I suppose HSQL knows from which table that field comes.I know that can be done somehow , I saw it beeing done in some similar software, I think it was/is named TOAD SQL or something similar. UPDATE b SET text='newvalue' WHERE text='oldvalue' Oh you are crazy, man. But to enlight you, how big pain in ass (not having this), can be: real example; Gqx/There is one null in right most column, but there are a couple more.
