|

/// - "-- { serverError 60 }" -- in case of you are expecting server error.

///
|
|
/// - "-- { clientError 20 }" -- in case of you are expecting client error.

///
|
|
/// - "-- { serverError FUNCTION_THROW_IF_VALUE_IS_NON_ZERO }" -- by error name.

///
|
|
/// - "-- { clientError FUNCTION_THROW_IF_VALUE_IS_NON_ZERO }" -- by error name.
|

///
|
|
/// Remember that the client parse the query first (not the server), so for
|
|
/// example if you are expecting syntax error, then you should use
|
|
/// clientError not serverError.
|
|
///
|
|
/// Examples:
|
|
///
|
|
/// - 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
|
|
/// is UNKNOWN_IDENTIFIER server error.
|
|
///
|
|
/// The following hints will control the query echo mode (i.e print each query):
|
|
///
|
|
/// - "-- { echo }"
|
|
/// - "-- { echoOn }"
|
|
/// - "-- { echoOff }"
