Question

我正在玩ClickHouse，我想插入行并从表中读取。但是在插入4-5K之后，当我尝试获取结果时，我的选择查询失败。当我查看日志文件时，似乎在服务器上执行某种合并会失败。

// ... 1. Performing a lot of inserts.
// Selecting one row
$query = ClickHouse::getInstance()->select(sprintf("SELECT * FROM %s WHERE %s %s",
    $tableName,
    ClickHouse::buildWhereColumns($where),
    $orderBy
), $where);

$row = $query->fetchOne();
// Gets this excetion:
/*
PHP Fatal error:  Uncaught ClickHouseDB\Exception\QueryException in vendor/smi2/phpclickhouse/src/Statement.php:174
