Coldfusion 8 Query feature

May 29, 2010 Leave a comment

This post is the extension of my earlier post – 10 March 2009

Actually I wrote about getting Identity column value, when inserting a new record in MSSQL data base. but few days ago I found out from Ben Forta’s blog, here is the link to that blog and content:

If you are using a database table with an identity (auto-increment) field, ColdFusion 8 can automatically return the newly created field value for you, without needing a trigger or a subsequent . All you need to do is look in the optional RESULT structure, and if available the value will just be there. This feature is very DBMS and driver specific (and unfortunately does not seem to be supported by Apache Derby), and the name of the structure member containing the generated value is different based on the DBMS being used. Here are the ones you should be aware of:

* SQL Server: result.IDENTITYCOL
* Oracle: result.ROWID
* Sybase: result.SYB_IDENTITY
* Informix: result.SERIAL_COL
* DB2: result.KEY_VALUE
* MySQL: result.GENERATED_KEY (MySQL 4 and 5 only, MySQL 3 does not support this feature)
