Specified by:

generateSQL in class ManualDiscretization

Parameters:

theTargetAttributeColumn - The Column to which this FeatureConstruction Operator is applied. Some subclasses may ignore this parameter.

Returns:

the SQL-function call

Throws:

M4CompilerError - A simple exception object with an error message.
