Evaluates a table expression in a context modified by filters.
The table expression to be evaluated.
A boolean (True/False) expression or a table expression that defines a filter.
The value is the result of the expression evaluated in a modified filter context.
Every filter argument can be either a filter removal (such as ALL, ALLEXCEPT, ALLNOBLANKROW), a filter restore (ALLSELECTED), or a table expression returning a list of values for one or more columns or for an entire expanded table.
When a filter argument has the form of a predicate with a single column reference, the expression is embedded into a FILTER expression that filters all the values of the referenced column. For example, the predicate shown in the first expression is internally converted in the second expression.
CALCULATETABLE ( <table_expression>, table[column] = 10 ) CALCULATE ( <table_expression>, FILTER ( ALL ( table[column] ), table[column] = 10 ) )
A filter argument overrides the existing corresponding filters over the same column(s), unless it is embedded within KEEPFILTERS.
CALCULATETABLE follow the same steps of CALCULATE to evaluate its result.
