> MEASURES: Defining Calculations for Use in the Query
> The MEASURES clause defines a list of columns for the pattern output table. Each pattern measure column is defined with a column name whose value is specified by a corresponding pattern measure expression.
> A value expression is defined with respect to the pattern variables. Value expression can contain set functions, pattern navigation operations, CLASSIFIER(), MATCH_NUMBER(), and column references to any column of the input table. See "Expressions in MEASURES and DEFINE" for more information.
