Data Structures

This section describes the data structures that you use to provide information to the Data Access Manager or that the Data Access Manager uses to provide information to your application.

You provide a pointer to an asynchronous parameter block as a parameter to the DBStartQuery, DBGetQueryResults, DBInit, DBEnd, DBGetSessionNum, DBKill, DBSend, DBSendItem, DBExec, DBState, DBGetErr, DBBreak, DBGetItem, and DBUnGetItem functions.

The query record specifies connection information and contains a handle to an array of one or more complete queries or query templates. The DBGetNewQuery function returns a handle to a query record, and you provide a handle to a query record as a parameter to the DBStartQuery and DBDisposeQuery functions.

You use the results record to store the data that was returned by a data source in response to a query. The results record is a parameter to the DBGetQueryResults and DBResultsToText functions.
