Traditional Business Query Language

When you compose a query with the traditional business query language (BQL), you work with the following classes:

• The classes that correspond to database tables (data access classes) and columns. For details on data access classes, see Data Access Classes in Traditional BQL.
• The classes that define data views in a graph and select data from the database in code (PXSelect classes). For more information on these classes, see PXSelect Classes.
• The classes that compose BQL statements, such as Select, Search, Where, OrderBy, And, and Add. For more information on these classes, see The Classes That Compose BQL Statements.
• The classes that pass parameters to BQL statements, such as Current, Required, Optional, Argument. For details on BQL parameters, see Parameters in Traditional BQL Statements.
