Notes

• Logical AND aggregation across all values in the group
• Returns FALSE if any value is FALSE
• Returns TRUE if all values are TRUE
• NULL values are ignored in the calculation
• Returns TRUE for empty groups (vacuous truth)
• Can be used with WHERE clause to filter before aggregation
• Can be used with GROUP BY clause for grouped aggregation

Examples

SELECT
    f1 := ZIP(ARRAY[TRUE, FALSE, TRUE] AS value).TRANSFORM(SELECT BOOL_AND(value)).UNWRAP_ONE(), -- AND of values
    f2 := ZIP(ARRAY[TRUE, TRUE, TRUE] AS value).TRANSFORM(SELECT BOOL_AND(value)).UNWRAP_ONE() -- AND of values
;
