getColumnName
public java.lang.String getColumnName()
- Description copied from interface:
FromObjectUsage
- Returns the name of the underlying Column, SelectObject etc.
FromObjectUsages generally return FROM.COLUMN as their SQL text where FROM
is the useable alias of the FromObject and COLUMN is a name. This method
returns just the name without FROM.
setColumnName
public void setColumnName(java.lang.String columnName)
getSQLText
public java.lang.String getSQLText()
- Description copied from interface:
SQLFragment
- Return the SQL for this fragment. This contains no validation - if the
implementation is incomplete it will just return what it has. Error
checking of fragments should be done using a SQLQueryBuilder.
- Returns:
- a string representing the SQL text for this object.
