Constructor Details

DB2MainframePlatform

public DB2MainframePlatform()

Method Details

initializePlatformOperators

protected void initializePlatformOperators()

Initialize any platform-specific operators

Overrides:

initializePlatformOperators in class DB2Platform

getSelectForUpdateString

public String getSelectForUpdateString()

INTERNAL: Used for pessimistic locking in DB2. Without the "WITH RS" the lock is not held. AS/400 does not support UPDATE type lock, so EXCLUSIVE is used instead.

Overrides:

getSelectForUpdateString in class DB2Platform

supportsOuterJoinsWithBrackets

public boolean supportsOuterJoinsWithBrackets()

INTERNAL: Return if brackets can be used in the ON clause for outer joins. Some DB2 versions on OS390 do not allow this.

Overrides:

supportsOuterJoinsWithBrackets in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

buildDatabaseTypes

protected Map<Class<?>,FieldDefinition.DatabaseType> buildDatabaseTypes()

Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Return the mapping of class types to database types for the schema framework.

Overrides:

buildDatabaseTypes in class DB2Platform

getTableCreationSuffix

public String getTableCreationSuffix()

Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

Get the String used on all table creation statements generated from the DefaultTableGenerator with a session using this project (DDL generation). This value will be appended to CreationSuffix strings stored on the DatabaseTable or TableDefinition.

Specified by:

getTableCreationSuffix in interface DDLPlatform

Overrides:

getTableCreationSuffix in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform
