Just now, I test three tires programming with MTS and Midas in nt4. Use AdoDataSet in AppServer to access Ms SqlServer 7, and there's a table include Blob field in client side. When I change properity [poFetchBlobsOnDemand] to true in DataProvider, and use fetchblob() in client side. It give me such prompt when running: "Project XXX raised exception class EOleException with messgage 'unable to find a record. No key specified'. proces stoped. Use Step or Run to continue." If I change ADODataset to Ttable with ODBC as connect way, and hook DataProvider to that table, it will works fine. Why?
