- Method Detail
  - getGenerationTiming
```
GenerationTiming getGenerationTiming()
```
    When is this value generated : NEVER, INSERT, ALWAYS (INSERT+UPDATE)
    
    Returns:
    
    When the value is generated.
  - referenceColumnsInSql
```
boolean referenceColumnsInSql()
```
    Should the column(s) be referenced in the INSERT / UPDATE SQL?
    This will be false most often to have a DDL-defined DEFAULT value be applied on INSERT. For trigger-generated values this could be true or false depending on whether the user wants the trigger to have access to some value for the column passed in.
    
    Returns:
    
    true indicates the column should be included in the SQL.
  - getReferencedColumnValues
```
java.lang.String[] getReferencedColumnValues()
```
    For columns that will be referenced in the SQL (per referenceColumnsInSql()), what value should be used in the SQL as the column value.
    
    Returns:
    
    The column value to be used in the SQL. null for any element indicates to use the Column defined value (Column.getWriteExpr()).
