Which statement is true of the Where operator when used within a variable?

The correct answer is A. It instructs the variable to calculate only where certain values are true.. The Where operator used within a Web Intelligence variable acts as a conditional filter, restricting the variable's calculation to only the rows where the specified condition is true.

Which statement is true of the Where operator when used within a variable?

Options

  • AIt instructs the variable to calculate only where certain values are true.
  • BIt modifies the HAVING clause of the SQL generated to calculate the measure expression.

Why each option

The Where operator used within a Web Intelligence variable acts as a conditional filter, restricting the variable's calculation to only the rows where the specified condition is true.

AIt instructs the variable to calculate only where certain values are true.Correct

The Where operator scopes the variable's formula so it only evaluates against rows satisfying the given condition, functioning as an inline filter on the calculation without modifying the underlying SQL query sent to the database.

BIt modifies the HAVING clause of the SQL generated to calculate the measure expression.

The HAVING clause filters aggregated results in SQL; the Where operator in a Web Intelligence variable does not modify the HAVING clause of the generated SQL.

CIt modifies the WHERE clause of the SQL generated to calculate the measure expression.

The Where operator in a variable context operates at the report/microcube level, not by rewriting the WHERE clause of the SQL sent to the database.

DIt is not necessary to place parentheses around the values listed after the Where operator.

Parentheses are required around the values listed after the Where operator to correctly delimit the condition; omitting them causes a formula error.
