目标: Execute Doctrine DBAL 4 queries and statement mutations with DsnParser connection options, un-prefixed named parameter keys, typed ParameterType and ArrayParameterType enums, and distinct fetchOne null vs false return shapes HOW
包: doctrine/dbal 4.4.4
环境: php

DriverManager::getConnection() throws DriverRequired when passed a raw 'url' parameter without driver or DsnParser
Connection::executeQuery() throws MissingNamedParameter if named parameter keys include a leading colon ':'
Connection query and execution methods throw TypeError if passed integer type constants instead of ParameterType or ArrayParameterType enums
ArrayParameterType::INTEGER expands array values in IN (?) clauses and safely converts empty arrays [] to IN (NULL)
Connection::fetchOne() returns null when a column is SQL NULL but returns false when no matching row exists
Connection::fetchAssociative() returns false on missing rows while fetchAllAssociative() and fetchFirstColumn() return empty arrays []
Connection::insert, update, and delete return the integer count of affected rows
