Field Detail

• SOURCE

  public static final ResultColumnReferenceStrategy SOURCE

  This strategy says to reference the result columns by the qualified column name found in the result source. This strategy is not strictly allowed by ANSI SQL but is Hibernate's legacy behavior and is also the fastest of the strategies; thus it should be used if supported by the underlying database.

• ALIAS

  public static final ResultColumnReferenceStrategy ALIAS

  For databases which do not support SOURCE, ANSI SQL defines two allowable approaches. One is to reference the result column by the alias it is given in the result source (if it is given an alias). This strategy says to use this approach.

  The other QNSI SQL compliant approach is ORDINAL.

• ORDINAL

  public static final ResultColumnReferenceStrategy ORDINAL

  For databases which do not support SOURCE, ANSI SQL defines two allowable approaches. One is to reference the result column by the ordinal position at which it appears in the result source. This strategy says to use this approach.

  The other QNSI SQL compliant approach is ALIAS.
