Constructor & Destructor Documentation

◆ __construct()

DatabaseOracle::__construct ( array $params )

Constructor and database handle and attempt to connect to the DB server.

IDatabase classes should not be constructed directly in external code. Database::factory() should be used instead.

Parameters

array $params Parameters passed from Database::factory()

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 52 of file DatabaseOracle.php.

References $wgDBprefix, global, and Hooks\run().

◆ __destruct()

Run a few simple sanity checks and close dangling connections.

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 63 of file DatabaseOracle.php.

References Wikimedia\Rdbms\Database\close().

Member Function Documentation

◆ addIdentifierQuotes()

DatabaseOracle::addIdentifierQuotes ( $s )

Quotes an identifier using backticks or "double quotes" depending on the database type.

MySQL uses backticks while basically everything else uses double quotes. Since MySQL is the odd one out here the double quotes are our generic and we implement backticks in DatabaseMysqlBase.

Parameters

string $s

Returns: string

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 1078 of file DatabaseOracle.php.

References $s, and DBO_DDLMODE.

Parameters

string | int | null | bool | Blob $s

Returns: string|int

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 1069 of file DatabaseOracle.php.

◆ affectedRows()

DatabaseOracle::affectedRows ( )

Get the number of rows affected by the last write query.

See also: https://secure.php.net/mysql_affected_rows

Returns: int

Definition at line 357 of file DatabaseOracle.php.

◆ aggregateValue()

DatabaseOracle::aggregateValue	(	$valuedata,

◆ buildGroupConcatField()

DatabaseOracle::buildGroupConcatField	(	$delim,
		$table,
		$field,

◆ insert()

DatabaseOracle::insert	(	$table,
		$a,
		$fname = `__METHOD__`,
		$options = `[]`
	)

INSERT wrapper, inserts an array into a table.

$a may be either:

A single associative array. The array keys are the field names, and the values are the values to insert. The values are treated as data and will be quoted appropriately. If NULL is inserted, this will be converted to a database NULL.
An array with numeric keys, holding a list of associative arrays. This causes a multi-row INSERT on DBMSs that support it. The keys in each subarray must be identical to each other, and in the same order.

Usually throws a DBQueryError on failure. If errors are explicitly ignored, returns success.

$options is an array of options, with boolean options encoded as values with numeric keys, in the same style as $options in IDatabase::select(). Supported options are:

IGNORE: Boolean: if present, duplicate key errors are ignored, and any rows which cause duplicate key errors are not inserted. It's possible to determine how many rows were successfully inserted using IDatabase::affectedRows().

Parameters

string	$table	Table name. This will be passed through Database::tableName().
array	$a	Array of rows to insert
string	$fname	Calling function name (use METHOD) for logs/profiling
array	$options	Array of options

Returns: bool

◆ limitResult()

DatabaseOracle::limitResult	(	$sql,
		$limit,
		$offset = `false`
	)

Construct a LIMIT query with optional offset.

This is used for query pages. The SQL should be adjusted so that only the first $limit rows are returned. If $offset is provided as well, then the first $offset rows should be discarded, and the next $limit rows should be returned. If the result of the query is not ordered, then the rows to be returned are theoretically arbitrary.

$sql is expected to be a SELECT, if that makes a difference.

The version provided by default works in MySQL and SQLite. It will very likely need to be overridden for most other DBMSes.

Parameters

string	$sql	SQL query we will append the limit too
int	$limit	The SQL limit
int \| bool	$offset	The SQL offset (default false)

◆ tableName()

DatabaseOracle::tableName	(	$name,
		$format = `'quoted'`

This does two important things: it quotes the table names to clean them up, and it adds a table prefix if only given a table name with no quotes.

All functions of this object which require a table name call this function themselves. Pass the canonical name to such functions. This is only needed when calling query() directly.

Note: This function does not sanitize user input. It is not safe to use this function to escape user input.

Parameters

string	$name	Database table name
string	$format	One of: quoted - Automatically pass the table name through addIdentifierQuotes() so that it can be used in a query. raw - Do not add identifier quotes to the table name

Returns: string Full database name

◆ upsert()

DatabaseOracle::upsert	(		$table,
		array	$rows,
		array	$uniqueIndexes,
		array	$set,
			$fname = `__METHOD__`
	)

INSERT ON DUPLICATE KEY UPDATE wrapper, upserts an array into a table.

This updates any conflicting rows (according to the unique indexes) using the provided SET clause and inserts any remaining (non-conflicted) rows.

$rows may be either:

A single associative array. The array keys are the field names, and the values are the values to insert. The values are treated as data and will be quoted appropriately. If NULL is inserted, this will be converted to a database NULL.
An array with numeric keys, holding a list of associative arrays. This causes a multi-row INSERT on DBMSs that support it. The keys in each subarray must be identical to each other, and in the same order.

It may be more efficient to leave off unique indexes which are unlikely to collide. However if you do this, you run the risk of encountering errors which wouldn't have occurred in MySQL.

Usually throws a DBQueryError on failure. If errors are explicitly ignored, returns success.

Since: 1.22

Parameters

string	$table	Table name. This will be passed through Database::tableName().
array	$rows	A single row or list of rows to insert
array	$uniqueIndexes	List of single field names or field name tuples
array	$set	An array of values to SET. For each array element, the key gives the field name, and the value gives the data to set that field to. The data will be quoted by IDatabase::addQuotes(). Values with integer keys form unquoted SET statements, which can be used for things like "field = field + 1" or similar computed values.
string	$fname	Calling function name (use METHOD) for logs/profiling
