This example shows the C code for a table operator.
The required inputs for this aggregation operator are:
- The input table (or table expression) specified in the FROM clause of the SELECT statement. For example:
CREATE TABLE tab1 (A INTEGER, B INTEGER, C INTEGER, D INTEGER); INSERT INTO tab1(1,2,3,4); INSERT INTO tab1(2,3,4,5);
- Each aggregate is a Custom clause, such as SUM_AGG(c1, c2) and AVG_AGG(c3).
