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

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 DatabaseBase::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 DatabaseBase::affectedRows().

Parameters:

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

	)

INSERT SELECT wrapper.

Takes data from a SELECT query and inserts it into another table.

Parameters:

string	$destTable	The table name to insert into
string \| array	$srcTable	May be either a table name, or an array of table names to include in a join.
array	$varMap	must be an associative array of the form array( 'dest1' => 'source1', ...). Source items may be literals rather than field names, but strings should be quoted with DatabaseBase::addQuotes()
array	$conds	Condition array. See $conds in DatabaseBase::select() for the details of the format of condition arrays. May be "*" to copy the whole table.
string	$fname	The function name of the caller, from __METHOD__

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
	$limit	Integer the SQL limit
	$offset	Integer\|bool the SQL offset (default false)

Exceptions:

DBUnexpectedError

Parameters:

string \| array	$table	Table name
string \| array	$vars	Field names
array	$conds	Conditions
string	$fname	Caller function name
string \| array	$options	Query options
	$join_conds	array\|string Join conditions

Returns:: object|bool

DatabaseOracle::sourceStream	(	$	fp,

		$	fname = `__METHOD__`,
		$	inputCallback = `false`
	)

Read and execute commands from an open file handle.

Returns true on success, error string or exception on failure (depending on object's error ignore settings).

Parameters:

	$fp	Resource: File handle
	$lineCallback	Callback: Optional function called before reading each query
	$resultCallback	Callback: Optional function called for each MySQL result
string	$fname	Calling function name
	$inputCallback	Callback: Optional function called for each complete query sent

Returns:: bool|string

DatabaseOracle::strencode ( $ s )

Wrapper for addslashes()

Parameters:

string $s to be slashed.

Returns:: string: slashed string.

DatabaseOracle::strictIPs ( )

Returns true if this database is strict about what can be put into an IP field.

Specifically, it uses a NULL value instead of an empty string.

Returns:: bool

DatabaseOracle::tableExists	(	$	table,
		$	fname = `__METHOD__`
	)

Query whether a given table exists (in the given schema, or the default mw one if not given)

Returns:: bool

Reimplemented from DatabaseBase.

References $res, and tableName().

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

Format a table name ready for use in constructing an SQL query.

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.

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

DatabaseOracle::textFieldSize	(	$	table,
		$	field
	)

Returns the size of a text field, or -1 for "unlimited".

Parameters:

$table	string
$field	string

Returns:: int

DatabaseOracle::timestamp ( $ ts = 0 )

Convert a timestamp in one of the formats accepted by wfTimestamp() to the format used for inserting into timestamp fields in this DBMS.

The result is unquoted, and needs to be passed through addQuotes() before it can be included in raw SQL.

Parameters:

$ts	string\|int

Returns:: string

DatabaseOracle::unionQueries	(	$	sqls,
		$	all
	)

Construct a UNION query This is used for providing overload point for other DB abstractions not compatible with the MySQL syntax.

Parameters:

array	$sqls	SQL statements to combine
	$all	Boolean: use UNION ALL

Returns:: String: SQL fragment

DatabaseOracle::update	(	$	table,
		$	values,
		$	conds,
		$	fname = `__METHOD__`,
		$	options = `array()`
	)

UPDATE wrapper.

Takes a condition array and a SET array.

Parameters:

	$table	String name of the table to UPDATE. This will be passed through DatabaseBase::tableName().
array	$values	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 DatabaseBase::addQuotes().
	$conds	Array: An array of conditions (WHERE). See DatabaseBase::select() for the details of the format of condition arrays. Use '*' to update all rows.
	$fname	String: The function name of the caller (from __METHOD__), for logging and profiling.
array	$options	An array of UPDATE options, can be: IGNORE: Ignore unique key conflicts LOW_PRIORITY: MySQL-specific, see MySQL manual.

Returns:: Boolean

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.

Parameters:

string	$table	Table name. This will be passed through DatabaseBase::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 DatabaseBase::addQuotes().
string	$fname	Calling function name (use __METHOD__) for logs/profiling
array	$options	of options

Returns:: bool
