cftransaction

Instructs the database management system to treat multiple database operations as a single transaction. Provides database commit and rollback processing.

Database manipulation tags

<cftransaction 
   action = "begin" or "commit" or "rollback"
   isolation = "read_uncommitted" or "read_committed" or 
      "repeatable_read" >
</cftransaction>

cfinsert, cfprocparam, cfprocresult, cfquery, cfqueryparam, cfstoredproc, cfupdate

Within a transaction block, you can do the following:

• Commit a database transaction by nesting the <cftransaction action = "commit"/> tag within the block
• Roll back a transaction by nesting the <cftransaction action = "rollback"/> tag within the block

(In these examples, the slash is alternate syntax that is the equivalent of an end tag.)

Within a transaction block, you can write queries to more than one database, but you must commit or rollback a transaction to one database before writing a query to another. Using CFML error handling, you control whether each transaction is committed, based on the success or failure of the database query. To control how the database engine performs locking during the transaction, use the isolation attribute.

<p>CFTRANSACTION can be used to group multiple queries that use CFQUERY
into one business event. Changes to data that is requested by the queries
are not committed to the datasource until all actions within the transaction 
block have executed successfully.
<p>This a view-only example.

<cftransaction>
   <cfquery name='makeNewCourse' datasource='Snippets'>
   INSERT INTO Courses
      (Number, Descript)
   VALUES
      ('#myNumber#', '#myDescription#')
   </cfquery>

   <cfquery name='insertNewCourseToList' datasource='Snippets'>
   INSERT INTO CourseList
      (CorNumber, CorDesc, Dept_ID,
      CorName, CorLevel, LastUpdate)
   VALUES
      ('#myNumber#', '#myDescription#', '#myDepartment#',
      '#myDescription#', '#myCorLevel#', #Now()#)
   </cfquery>
</cftransaction>
