I have a multisource dynamic vdb with just two models
- one connected to a mssqlserver datasource A
- one connected to a mysqlserver datasource B
with full rights on both.
I would like to "replicate" a table from A to B, keeping the same exact structure.
This could be needed at least once a day (overnight), the more, the better.
The target table could be from few thousands rows to half a million
I digged a bit in to possible uses of:
- SELECT INTO syntax but while it works with simple statements like "select 1 as id into A.test" (still quite unuseful to me), docs say it's deprecated
- INSERT INTO, with something like "INSERT INTO A.tablename (field1,field2) VALUES (value1,value2)"an dthis also works (pk not insereted, autoincrementing)
I never thought of useing Teiid like this, up to now, but what I wish if possible, would be to keep the B.table as soon as possible in sync with A.table
I know there are other solutions to do db sync (like SymmetricDS, eg) but I can't touch the A source (so I can't insert triggers there..)
Is this possible, atm, and what is the best approach in Teiid, if yes?
(probably related to Insert Into Support)
I also tried this
insert into dbtestB.table (DocumentDate, AccrualDate, LogNo, DocNo,FeeId)
select DocumentDate, AccrualDate, LogNo, DocNo,FeeId from dbtestA.table
but I get
