public class PervasivePlatform
extends DatabasePlatform

Purpose: Provides Pervasive SQL DBMS specific behavior.

Pervasive SQL Platform file
Contributed by: Pervasive Software, Inc.
Contributed under bug: 392109

Developed on Pervasive PSQL Server 11.30

• Eclipselink Core SRG Test passes with known limitations.
• Eclipselink JPA SRG Test passes with known limitations.
• Eclipselink stored procedure tests "CustomSQLTestModel", "StoredProcedureGeneratorModel" pass with known limitations.

Limitations

• Updates are not supported on joined queries or queries with group by.
• The platform method getSelectForUpdateString() currently returns an empty string. This is to avoid avoid joined queries with FOR UPDATE in them, which Pervasive does not support.
• Columns used in indexes must total no more than 255 bytes in length.
• Pervasive SQL does not support dynamic parameters in the SELECT list.
• IDENTITY columns are either 2- or 4-byte integers. Foreign keys referencing such columns must use the same datatypes.
