|

/// - echo 'select / -- { clientError 62 }' | clickhouse-client --testmode -nm

|
|
// Here the client parses the query but it is incorrect, so it expects

/// SYNTAX_ERROR (62).

/// - echo 'select foo -- { serverError 47 }' | clickhouse-client --testmode -nm

/// But here the query is correct, but there is no such column "foo", so it
