Please can I have the right syntax to use for retrieving the last inserted id after creating a record?

I have this which returns 0

Code: Select all

command mlteSales_CreateSales pRecordA
   local tSqlQuery, tSqlParamsA, tRowid
   sqlquery_create "sales", pRecordA
   put the result into theError
   put it into theAffectedRows
   -- now get the brand new id
   return tRowid
end mlteSales_CreateSales

"lastInsertedID" might not be what you want, read the documentation about. It'a a highly situational function ...

To get the last value of a auto-increment ID, usually:

Code: Select all

does the job - as long as the last insert didn't re-use a "ID hole" from a previously deleted record. But since such can only occur due to "manual" overrides of the auto-increment, you should know about ;-)

Assuming SQLYogas "lastInsertedID" does what the equally named MySQL function does, and that you can translate my SQL to SQLYoga, hope I could help ;-)

Have fun!

@nrprioleau - in your function tRowId is never set to anything. dbconn_lastInsertedID puts the id into the it variable. You would want to return it rather than tRowId. Or put it into tRowId and then return tRowId.
