Abstract

The invention discloses a display method for a multi-field database. The method comprises the following steps of: configuring database parameters and generating a database configuration file and a database structured query language (SQL) statement file by using the configured database parameters; configuring interface parameters which comprise the length and the width of database fields which are displayed on an interface and the line number and the column number which are required to be displayed on the interface; correlating the database with the interface, namely correlating the database configuration file and the database SQL statement file with the interface by using connecting strings; and compiling the interface by using a compiler in an interface development environment, and displaying contents in the database according to the set line number and column number on the compiled interface. The display method and the display device for the multi-field database can be widely applied to the design and the development of the interfaces of various application software systems and are extremely high in practicability.

Description

technical field [0001] The invention relates to the technical field of database display, in particular to a display method and display device for a multi-field database. Background technique [0002] At present, in the field of industrial control, the data of the human-computer interaction interface (hereinafter referred to as the interface) generally comes from the database, and the interface generally needs to have functions such as adding, deleting, querying, and updating. For most control systems, the display function It is the most important and the most prone to demand changes. [0003] Many database tables in the field of industrial control often have many fields, and often a database record has more than 30 fields, reaching hundreds, or hundreds of fields. For the display of this multi-field database data, the general method is to manually edit the interface by the developer and fill it in one by one. If a table has 30 fields, in order to display a database record, ...
