Any condition can be specified as an argument (as in [WHERE](https://clickhouse.com/docs/en/sql-reference/statements/select/where#select-where)). The conditions, except the first, apply in pairs: the result of the second will be true if the first and second are true, of the third if the first and third are true, etc. Syntax retention(cond1, cond2, ..., cond32); Arguments `cond` — An expression that returns a `UInt8` result (1 or 0). Returned value The array of 1 or 0. 1 — Condition was met for the event. 0 — Condition wasn’t met for the event. Type: `UInt8`. ## Checklist(Required) 1.
