Field Detail

• changedColumnIds

  int[] changedColumnIds

  This class implements Formatable. But it is NOT used across either major or minor releases. It is only written persistently in stored prepared statements, not in the replication stage. SO, IT IS OK TO CHANGE ITS read/writeExternal.

• positionedUpdate

  private boolean positionedUpdate

• numColumns

  int numColumns

• schemaName

  private java.lang.String schemaName

• tableName

  private java.lang.String tableName

• columnNames

  private java.lang.String[] columnNames

• identitySequenceUUIDString

  java.lang.String identitySequenceUUIDString

• autoincRowLocation

  RowLocation[] autoincRowLocation

  An array of row location objects (0 based), one for each column in the table. If the column is an autoincrement table then the array points to the row location of the column in SYSCOLUMNS. if not, then it contains null.

• autoincIncrement

  private long[] autoincIncrement

Constructor Detail

• UpdateConstantAction

  public UpdateConstantAction()
