Name
CFTRANSACTION
Synopsis
<CFTRANSACTION>
CFML code
</CFTRANSACTION>Treats all query operations between
<CFTRANSACTION>/</CFTRANSACTION>
tags as a single transaction. Changes to the database aren’t
committed until all queries in the transaction have executed
successfully. In the event that a query within the transaction fails,
all previous queries are automatically rolled back.
CFTRANSACTION tags may be nested to allow portions
of the transaction to be committed or rolled back within the main
CFTRANSACTION block. More than one database may be
written to within a single CFTRANSACTION block if
each transaction is committed or rolled back prior to writing a query
to the next database. Exception handling using
CFTRY/CFCATCH gives you full
control over how queries are committed and rolled back within
CFTRANSACTION blocks.
