Re: ADO RDD xHarbour

Lucas, In the app we are working browses are not a problem. All work well without a single changed line. My worry is with transactions. The app works 99% like this: First closes and add all records to all tables necessary to the trans. If all goes well loop through those records in ...

Re: ADO RDD xHarbour

Re: Help with a Mysql query

... Here is a sample. This sample creates a PROD_GRP table (which you referred to as catalog above) and a transaction table, SALES_TRN with 500,000 transactions.
