Assumptions

The Query Reference Manual describes the Query command syntax which you can use to set up links between Plant and an external DB. It is intended for those who need to write application macros for use from within those products, the principal purpose of such macros being to allow Users to interrogate a DB and to use the results to control Plant operations in a User-friendly manner. The manual does not attempt to define rules for writing such macros, nor does it tell you how you should document the ways in which end-Users should use your macros and their controlling interfaces.

The manual assumes that you have some prior experience of programming and that you are already familiar with the following aspects:

• The functions of Plant and the ways in which these are controlled via the standard User interface.

• The data server commands necessary to insert, delete, query and protect data in your chosen DB.

• The concepts of writing and running macro command files, including the use of Programmable Macro Language (PML). For more information, refer to the Software Customisation Guide.

• The design and implementation of a forms and menus Graphical User Interface.
