Detailed Description

MergeQueries

This file contains the arguments that can be used in functions for Query Callbacks. In addition to the options in this file, the following arguments can be added as well:

• TQueryContext - Addition is typically required to interact with TEDS, e.g. to add/remove columns.
• Columns - When using the single row mode any column with data can be added by reference and it will automatically be bound. Note that the use of const is important as it will determine if read-only or read-write access is requested from TEDS, which can have performance implications as read-only generally provides better parallelization.
