Field Detail

• aiCache

  protected DataValueDescriptor[] aiCache

  keeps track of autoincrement values that are generated by getSetAutoincrementValues.

• identitySequenceUUIDString

  protected java.lang.String identitySequenceUUIDString

  protected ResultSet autoGeneratedKeysResultSet

• autoGeneratedKeysRowsHolder

  protected TemporaryRowHolderImpl autoGeneratedKeysRowsHolder

• autoGeneratedKeysColumnIndexes

  protected int[] autoGeneratedKeysColumnIndexes

• autoincrementGenerated

  Parameters:

  activation - an activation

  Throws:

  StandardException - on error

Method Detail

• getSetAutoincrementValue

  public NumberDataValue getSetAutoincrementValue​(int columnPosition,
                                                  long increment)
                                           throws StandardException

  getSetAutoincrementValue will get the autoincrement value of the columnPosition specified for the target table. If increment is non-zero we will also update the autoincrement value.

  Parameters:

  columnPosition - position of the column in the table (1-based)

  increment - amount of increment.

  Throws:

  StandardException - if anything goes wrong.

• saveAIcacheInformation

  public void saveAIcacheInformation​(java.lang.String schemaName,
                                     java.lang.String tableName,
                                     java.lang.String[] columnNames)
                              throws StandardException

  Throws:

  StandardException

• verifyAutoGeneratedRScolumnsList

  protected void verifyAutoGeneratedRScolumnsList​(UUID targetUUID)
                                           throws StandardException

  Throws:

  StandardException

• verifyAutoGeneratedColumnsIndexes

  private void verifyAutoGeneratedColumnsIndexes​(int[] columnIndexes,
                                                 UUID targetUUID)
                                          throws StandardException

  Verify that the auto-generated columns list (by position) has valid column positions for the table.

  Throws:

  StandardException

• verifyAutoGeneratedColumnsNames

  private void verifyAutoGeneratedColumnsNames​(java.lang.String[] columnNames,
                                               UUID targetUUID)
                                        throws StandardException

  Verify that the auto-generated columns list (by name) has valid column names for the table. If all the column names are valid, convert column names array to corresponding column positions array Save that column positions array in activation. We do this to simplify the rest of the logic(it only has to deal with column positions here after).

  Throws:

  StandardException - Thrown on error if invalid column name in the list.

• verifyAutoGenColumn

  private boolean verifyAutoGenColumn​(ColumnDescriptor cd)

  Check that the received ColumnDescriptor corresponds to a column for which it is possible to fetch auto-generated keys.

• firstExecuteSpecialHandlingAutoGen

  protected void firstExecuteSpecialHandlingAutoGen​(boolean firstExecute,
                                                    RowChanger rowChanger,
                                                    UUID targetUUID)
                                             throws StandardException

  Throws:

  StandardException

• generatedColumnPositionsArray

  private int[] generatedColumnPositionsArray​(UUID targetUUID)
                                       throws StandardException

  If user didn't provide columns list for auto-generated columns, then only include columns with auto-generated values in the resultset. Those columns would be ones with default value defined.

  Throws:

  StandardException

• uniqueColumnPositionArray

  private int[] uniqueColumnPositionArray​(int[] columnIndexes,
                                          UUID targetUUID)
                                   throws StandardException

  Remove duplicate columns from the array. Then use this array to generate a sub-set of insert resultset to be returned for JDBC3.0 getGeneratedKeys() call.

  Throws:

  StandardException

• getCompactRow

  protected ExecRow getCompactRow​(ExecRow inputRow,
                                  int[] columnIndexes)
                           throws StandardException

  Take the input row and return a new compact ExecRow using the column positions provided in columnIndexes. Copies references, no cloning.

  Throws:

  StandardException
