Simplifying database interactions with Doctrine DBALI previously wrote about switching from the mysql extension to PDO. PDO introduces a number of convenient dbal connection prepare beyond the mysql extension hgh supplements height increase as transactions, prepared statements, and more fetching options. However there are still a few things that cnonection a bit painful. It adds a few conveniences beyond straight PDO as well dbal connection prepare a query builder. There are a number of projects under the Doctrine umbrella including a full ORM.

Prepares and executes an SQL query and returns the first row of the result as a numerically indexed array. Prepares and executes an SQL query and returns the value of a single column of the first row of the result. Quote a string so it can be safely used as a table or column name, even if it is a reserved name. In general, they end up causing way more problems than they solve.
If the query is parameterized, a prepared statement is used. If an SQLLogger is configured, the execution is logged. Returns the ID of the last inserted row, or the last value from a sequence object, depending on the underlying driver.
If an exception occurs during execution of the function or transaction commit, the transaction is rolled back and the exception re-thrown. Returns the savepoint name to use for nested transactions are false if they are not supported "savepointFormat" parameter is not set.
Gets the SchemaManager that can be used to inspect or change the database schema through the connection. Marks the current transaction so that the only possible outcome for the transaction to be rolled back. Converts a given value to its database representation according to the conversion rules of a specific DBAL mapping type.
The DatabasePlatform object that provides information about the database platform used by the connection. Overview Namespace Class Tree Download. Initializes a new instance of the Connection class.
Gets the parameters used during instantiation. Gets the name of the database this Connection is connected to. Gets the hostname of the currently connected database. Gets the port of the currently connected database.
Gets the username used by this connection. Gets the password used by this connection. Gets the DBAL driver instance. Gets the Configuration used by the Connection. Gets the EventManager used by the Connection. Gets the DatabasePlatform for the connection. Gets the ExpressionBuilder for the connection. Establishes the connection with the database. Whether an actual connection to the database is established.
Checks whether a transaction is currently active. An associateve array containing column-value pairs. Sets the transaction isolation level.
Gets the currently active transaction isolation level. Returns integer The current transaction isolation level. An associative array containing column-value pairs.

Quotes a given input parameter. Prepares and executes an SQL query and returns the result as an associative array. Prepares an SQL statement. Executes an, optionally parameterized, SQL query. The function receives a single paramater, an array, that represents a row of the result set.
Executes an SQL statement, returning a result set as a Statement object. Execute an SQL statement and return the number of affected rows.
Returns the current transaction nesting level. Returns integer The nesting level. A value of 0 means there's no active transaction. Returns integer The last error code. Fetch extended error information associated with the last database operation. Returns array The last error information. Executes a function in a transaction.
The function gets passed this Connection instance as an optional parameter. Get if nested transactions should use savepoints Returns boolean boolean. Returns the savepoint name to use for nested transactions are false if they are not supported "savepointFormat" parameter is not set Returns mixed a string with the savepoint name or false. Starts a transaction by suspending auto-commit mode. Commits the current transaction.
Cancel any database changes done during the current transaction. Gets the wrapped driver connection. Check whether the current transaction is marked for rollback only.
Create a new instance of a SQL query builder. Represents an array of ints to be expanded by Doctrine SQL parsing. Represents an array of strings to be expanded by Doctrine SQL parsing.
Returns integer The number of affected rows. Returns string The quoted name. Returns string The quoted parameter. Returns mixed The projected result of the query. Returns string A string representation of the last inserted ID. Returns mixed The converted value. Returns mixed The converted type. The wrapped driver connection. The used DBAL driver.
