> Hi,

> May be there is more elegant way? I am using ADODB. ADODB has function

> 
> This is from ADODB manual:

> Insert_ID( )
> Returns the last autonumbering ID inserted. Returns false if function 
> not supported.
> Only supported by databases that support auto-increment or object id's, 
> such as PostgreSQL, MySQL and MSSQL currently. PostgreSQL returns the 
> OID, which can change on a database reload.
