    • computeMaxRowsForSQL

      public int computeMaxRowsForSQL(int firstResultIndex, int maxResults)
      INTERNAL: Use the JDBC maxResults and firstResultIndex setting to compute a value to use when limiting the results of a query in SQL. These limits tend to be used in two ways. 1. MaxRows is the index of the last row to be returned (like JDBC maxResults) 2. MaxRows is the number of rows to be returned H2 uses case #2 and therefore the maxResults has to be altered based on the firstResultIndex.
      Overrides:
      computeMaxRowsForSQL in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

    • isDynamicSQLRequiredForFunctions

      public boolean isDynamicSQLRequiredForFunctions()
      INTERNAL H2 has some issues with using parameters on certain functions and relations. This allows statements to disable binding only in these cases.
      Overrides:
      isDynamicSQLRequiredForFunctions in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

    • allowBindingForSelectClause

      public boolean allowBindingForSelectClause()
      Overrides:

    • buildSelectQueryForSequenceObject

      public ValueReadQuery buildSelectQueryForSequenceObject(String seqName, Integer size)
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
      INTERNAL: Returns query used to read value generated by sequence object (like Oracle sequence). In case the other version of this method (taking no parameters) returns null, this method is called every time sequence object NativeSequence reads. If the platform supportsSequenceObjects then (at least) one of buildSelectQueryForSequenceObject methods should return non-null query.
      Overrides:
      buildSelectQueryForSequenceObject in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

    • supportsIdentity

      public boolean supportsIdentity()
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
      INTERNAL: Indicates whether the platform supports identity. This method is to be used *ONLY* by sequencing classes
      Overrides:
      supportsIdentity in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

    • supportsSequenceObjects

      public boolean supportsSequenceObjects()
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
      INTERNAL: Indicates whether the platform supports sequence objects. This method is to be used *ONLY* by sequencing classes
      Overrides:
      supportsSequenceObjects in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

    • buildSelectQueryForIdentity

      public ValueReadQuery buildSelectQueryForIdentity()
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
      INTERNAL: Returns query used to read back the value generated by Identity. This method is called when identity NativeSequence is connected, the returned query used until the sequence is disconnected. If the platform supportsIdentity then (at least) one of buildSelectQueryForIdentity methods should return non-null query.

      Alternatively, if the platform supports Statement.getGeneratedKeys(), see DatasourcePlatform.supportsReturnGeneratedKeys()

      Overrides:
      buildSelectQueryForIdentity in class org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform

    • printFieldIdentityClause

      public void printFieldIdentityClause(Writer writer) throws ValidationException
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatabasePlatform
      Append the receiver's field 'identity' constraint clause to a writer.
      Overrides:

      Throws:
      ValidationException

    • supportsForeignKeyConstraints

      public boolean supportsForeignKeyConstraints()
      Overrides:
      supportsForeignKeyConstraints in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

    • supportsGlobalTempTables

      public boolean supportsGlobalTempTables()
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatabasePlatform
      INTERNAL: Indicates whether the platform supports global temporary tables. "Global" means that an attempt to create temporary table with the same name for the second time results in exception. EclipseLink attempts to create global temporary table in the beginning of UpdateAllQuery, execution and assumes that it already exists in case SQLException results. In the end of UpdateAllQuery execution all rows are removed from the temporary table - it is necessary in case the same temporary table will be used by another UpdateAllQuery in the same transaction. Override this method if the platform supports global temporary tables. Note that this method is ignored in case supportsLocalTempTables() returns true.
      Overrides:
      supportsGlobalTempTables in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

    • getCreateTempTableSqlPrefix

      protected String getCreateTempTableSqlPrefix()
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatabasePlatform
      INTERNAL: Override this method if the platform supports temporary tables. This should contain the beginning of sql string for creating temporary table - the sql statement name, for instance: "CREATE GLOBAL TEMPORARY TABLE ". Don't forget to end it with a space.
      Overrides:
      getCreateTempTableSqlPrefix in class org.eclipse.persistence.internal.databaseaccess.DatabasePlatform

    • writeUpdateOriginalFromTempTableSql

      public void writeUpdateOriginalFromTempTableSql(Writer writer, org.eclipse.persistence.internal.helper.DatabaseTable table, Collection pkFields, Collection assignedFields) throws IOException

      Parameters:
      writer - for writing the sql
      table - is original table for which temp table is created.
      pkFields - primary key fields for the original table.
      assignedFields - fields to be assigned a new value.

      public ValueReadQuery getTimestampQuery()
      Description copied from class: org.eclipse.persistence.internal.databaseaccess.DatasourcePlatform
      This method can be overridden by subclasses to return a query that will return the timestamp from the server. return null if the time should be the local time.
