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.
