SUM ( CASE WHEN d.DCG between = and THEN ELSE END) AS 1. A sequence of two-sided formulas. The left hand side (LHS) determines which values match this case. The right hand side (RHS) provides the replacement value.

The LHS must evaluate to a logical vector. The RHS does need to be logical, but all RHSs must evaluate to the same type of vector. Both LHS and RHS may have the same length of either or n. The CASE expression returns a result whose data type depends on the context where it is used. For example, if the CASE expression is used in the character string context, it returns the result as a character string. If the CASE expression is used in a numeric context, it returns the result as an integer, a decimal, or a real value.
