                          throws SQLException
Description copied from interface: FieldConverter
Convert a default string object and return the appropriate argument to a SQL insert or update statement.

Specified by:
parseDefaultString in interface FieldConverter
Specified by:
parseDefaultString in class BaseDataType
Throws:
SQLException

resultToSqlArg

public Object resultToSqlArg(FieldType fieldType,
                             DatabaseResults results,

                      throws SQLException
Description copied from interface: FieldConverter
Return the SQL argument object extracted from the results associated with column in position columnPos.

Specified by:
resultToSqlArg in interface FieldConverter
Specified by:
resultToSqlArg in class BaseDataType
Parameters:
fieldType - Associated FieldType which may be null.
Throws:
SQLException - If there is a problem accessing the results data.

sqlArgToJava

public Object sqlArgToJava(FieldType fieldType,

Specified by:
sqlArgToJava in interface FieldConverter
Overrides:
sqlArgToJava in class BaseFieldConverter
Parameters:
fieldType - Associated FieldType which may be null.
sqlArg - SQL argument converted with FieldConverter.resultToSqlArg(FieldType, DatabaseResults, int) which will not be null.
