': ' . $row['total_views'] . PHP_EOL; } ``` ### Additional types [](#additional-types) If you want to use [Array(T) type](https://clickhouse.yandex/reference_en.html#Array(T)), register additional DBAL types in your code: ``` // register all custom DBAL Array types ArrayType::registerArrayTypes($conn->getDatabasePlatform()); // register one custom DBAL Array(Int8) type Type::addType('array(int8)', 'FOD\DBALClickHouse\Types\ArrayInt8Type'); ``` or register them in Symfony configuration file: ``` # app/config/config.yml doctrine: dbal: connections: ... types: array(int8): FOD\DBALClickHouse\Types\ArrayInt8Type array(int16): FOD\DBALClickHouse\Types\ArrayInt16Type array(int32): FOD\DBALClickHouse\Types\ArrayInt32Type array(int64): FOD\DBALClickHouse\Types\ArrayInt64Type array(uint8): FOD\DBALClickHouse\Types\ArrayUInt8Type array(uint16): FOD\DBALClickHouse\Types\ArrayUInt16Type array(uint32): FOD\DBALClickHouse\Types\ArrayUInt32Type array(uint64): FOD\DBALClickHouse\Types\ArrayUInt64Type array(float32): FOD\DBALClickHouse\Types\ArrayFloat32Type array(float64): FOD\DBALClickHouse\Types\ArrayFloat64Type array(string): FOD\DBALClickHouse\Types\ArrayStringType array(datetime): FOD\DBALClickHouse\Types\ArrayDateTimeType array(date): FOD\DBALClickHouse\Types\ArrayDateType ``` Additional type `BigIntType` helps you to store bigint values as [Int64/UInt64](https://clickhouse.yandex/reference_en.html#UInt8,%20UInt16,%20UInt32,%20UInt64,%20Int8,%20Int16,%20Int32,%20Int64) value type in ClickHouse. You can override DBAL type in your code: ``` Type::overrideType(Type::BIGINT, 'FOD\DBALClickHouse\Types\BigIntType'); ``` or use custom mapping types in Symfony configuration: ``` # app/config/config.yml doctrine: dbal: types: bigint: FOD\DBALClickHouse\Types\BigIntType ... ``` ### More information in Doctrine DBAL documentation: [](#more-information-in-doctrine-dbal-documentation) - [Data Retrieval And Manipulation](http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/data-retrieval-and-manipulation.html) - [SQL Query Builder](http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/query-builder.html) - [Schema-Representation](http://docs.doctrine-project.org/projects/doctrine-dbal/en/latest/reference/schema-representation.html) ### Health Score 28 — LowBetter than 52% of packages Maintenance20 Infrequent updates — may be unmaintained Popularity6 Limited adoption so far Community12 Small or concentrated contributor base Maturity63 Established project with proven stability Bus Factor1 Top contributor holds 89.7% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
