addQuotes ( $s)

attachDatabase ( $name, $file=false, $fname=__METHOD__)

Attaches external database to the connection handle. More...

databasesAreIndependent ()

Returns true if DBs are assumed to be on potentially different servers.In systems like mysql/mariadb, different databases can easily be referenced on a single connection merely by name, even in a single query via JOIN. On the other hand, Postgres treats databases as logically separate, with different database users, requiring special mechanisms like postgres_fdw to "mount" foreign DBs. This is true even among DBs on the same server. Changing the selected database via selectDomain() requires a new connection.

deleteJoin ( $delTable, $joinTable, $delVar, $joinVar, $conds, $fname=__METHOD__)

Delete all rows in a table that match a condition which includes a join.For safety, an empty $conds will not delete everything. If you want to delete all rows where the join condition matches, set $conds=IDatabase::ALL_ROWS.DO NOT put the join condition in $conds.This operation will be seen by affectedRows()/insertId() as one query statement, regardless of how many statements are actually sent by the class implementation.

Parameters

string	$delTable	The table to delete from.
string	$joinTable	The reference table used by the join (not modified).
string	$delVar	The variable to join on, in the first table.
string	$joinVar	The variable to join on, in the second table.
array \| string	$conds	Condition array of field names mapped to variables, ANDed together in the WHERE clause

estimateRowCount ( $tables, $var=' *', $conds='', $fname=__METHOD__, $options=[], $join_conds=[])

Estimate the number of rows in dataset.MySQL allows you to estimate the number of rows that would be returned by a SELECT query, using EXPLAIN SELECT. The estimate is provided using index cardinality statistics, and is notoriously inaccurate, especially when large numbers of rows have recently been added or deleted.For DBMSs that don't support fast result size estimation, this function will actually perform the SELECT COUNT(*).Takes the same arguments as IDatabase::select().New callers should use newSelectQueryBuilder with SelectQueryBuilder::estimateRowCount instead, which is more readable and less error-prone.

Parameters

string \| string[]	$tables	Table name(s)
string	$var	Column for which NULL values are not counted [default "*"]
array \| string	$conds	Filters on the table
string	$fname	Function name for profiling
array	$options	Options for select
array \| string	$join_conds	Join conditions

Returns: int Row count

Constructor & Destructor Documentation

◆ __construct()

Wikimedia\Rdbms\DatabaseSqlite::__construct ( array $params )

Additional params include:

dbDirectory : directory containing the DB and the lock file directory
dbFilePath : use this to force the path of the DB file
trxMode : one of (deferred, immediate, exclusive)
Parameters

array $params

Member Function Documentation

◆ addQuotes()

Wikimedia\Rdbms\DatabaseSqlite::addQuotes ( $s )

Parameters

Returns: string

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 672 of file DatabaseSqlite.php.

◆ attachDatabase()

Wikimedia\Rdbms\DatabaseSqlite::attachDatabase	(	$name,
		$file = `false`,
		$fname = `__METHOD__`
	)

Attaches external database to the connection handle.

See also: https://sqlite.org/lang_attach.html

Parameters

string	$name	Database name to be used in queries like SELECT foo FROM dbname.table
bool \| string	$file	Database file name. If omitted, will be generated using $name and configured data directory
string	$fname	Calling function name

Returns: IResultWrapper

Definition at line 369 of file DatabaseSqlite.php.

References $file.

◆ closeConnection()

Wikimedia\Rdbms\DatabaseSqlite::closeConnection ( )

protected

Does not actually close the connection, just destroys the reference for GC to do its work.

Returns: bool

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 277 of file DatabaseSqlite.php.

◆ databasesAreIndependent()

Wikimedia\Rdbms\DatabaseSqlite::databasesAreIndependent ( )

Returns true if DBs are assumed to be on potentially different servers.In systems like mysql/mariadb, different databases can easily be referenced on a single connection merely by name, even in a single query via JOIN. On the other hand, Postgres treats databases as logically separate, with different database users, requiring special mechanisms like postgres_fdw to "mount" foreign DBs. This is true even among DBs on the same server. Changing the selected database via selectDomain() requires a new connection.

Returns: bool

◆ doSingleStatementQuery()

Wikimedia\Rdbms\DatabaseSqlite::doSingleStatementQuery ( string $sql )

protected

Run a query and return a QueryStatus instance with the query result information.

This is meant to handle the basic command of actually sending a query to the server via the driver. No implicit transaction, reconnection, nor retry logic should happen here. The higher level query() method is designed to handle those sorts of concerns. This method should not trigger such higher level methods.

The lastError() and lastErrno() methods should meaningfully reflect what error, if any, occurred during the last call to this method. Methods like executeQuery(), query(), select(), insert(), update(), delete(), and upsert() implement their calls to doQuery() such that an immediately subsequent call to lastError()/lastErrno() meaningfully reflects any error that occurred during that public query method call.

For SELECT queries, the result field contains either:

a) A driver-specific IResultWrapper describing the query results
b) False, on any query failure

For non-SELECT queries, the result field contains either:

a) A driver-specific IResultWrapper, only on success
b) True, only on success (e.g. no meaningful result other than "OK")
c) False, on any query failure

Parameters

string $sql Single-statement SQL query

Returns: QueryStatus

◆ setTableAliases()

Wikimedia\Rdbms\DatabaseSqlite::setTableAliases ( array $aliases )

Make certain table names use their own database, schema, and table prefix when passed into SQL queries pre-escaped and without a qualified database name.

For example, "user" can be converted to "myschema.mydbname.user" for convenience. Appearances like user, somedb.user, somedb.someschema.user will used literally.

Calling this twice will completely clear any old table aliases. Also, note that callers are responsible for making sure the schemas and databases actually exist.

Parameters

array[] $aliases Map of (table => (dbname, schema, prefix) map)
