Public Member Functions

__construct (array $params)

Additional params include: More...

addQuotes ( $s)

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

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

buildConcat ( $stringList)

Build a concatenation list to feed into a SQL query. More...

buildGreatest ( $fields, $values)

Build a GREATEST function statement comparing columns/values.Integer and float values in $values will not be quotedIf $fields is an array, then each value with a string key is treated as an expression (which must be manually quoted); such string keys do not appear in the SQL and are only descriptive aliases.

Parameters

string \| string[]	$fields	Name(s) of column(s) with values to compare
string \| int \| float \| string[] \| int[] \| float[]	$values	Values to compare

Returns: mixed

Since: 1.35

Stability: stable: to override

More...

buildGroupConcatField ( $delim, $table, $field, $conds='', $join_conds=[])

Build a GROUP_CONCAT or equivalent statement for a query.This is useful for combining a field for several rows into a single string. NULL values will not appear in the output, duplicated values will appear, and the resulting delimiter-separated values have no defined sort order. Code using the results may need to use the PHP unique() or sort() methods.

Parameters

string	$delim	Glue to bind the results together
string \| array	$table	Table name
string	$field	Field name
string \| array	$conds	Conditions
string \| array	$join_conds	Join conditions

Returns: string SQL text

Since: 1.23

Stability: stable: to override

More...

buildLeast ( $fields, $values)

Build a LEAST function statement comparing columns/values.Integer and float values in $values will not be quotedIf $fields is an array, then each value with a string key is treated as an expression (which must be manually quoted); such string keys do not appear in the SQL and are only descriptive aliases.

Parameters

string \| string[]	$fields	Name(s) of column(s) with values to compare
string \| int \| float \| string[] \| int[] \| float[]	$values	Values to compare

Returns: mixed

Since: 1.35

Stability: stable: to override

buildStringCast ( $field)

buildSubstring ( $input, $startPosition, $length=null)

Stability: stable: to override

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 where the condition is a join.MySQL overrides this to use a multi-table DELETE syntax, in other databases we use sub-selectsFor 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.

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().

Parameters

string	$var	Column for which NULL values are not counted [default "*"]
array \| string	$conds	Filters on the table

◆ buildConcat()

Wikimedia\Rdbms\DatabaseSqlite::buildConcat ( $stringList )

Build a concatenation list to feed into a SQL query.

Parameters

string[] $stringList

Returns: string

Reimplemented from Wikimedia\Rdbms\Database.

Definition at line 861 of file DatabaseSqlite.php.

◆ buildGreatest()

Wikimedia\Rdbms\DatabaseSqlite::buildGreatest	(	$fields,
		$values
	)

Build a GREATEST function statement comparing columns/values.Integer and float values in $values will not be quotedIf $fields is an array, then each value with a string key is treated as an expression (which must be manually quoted); such string keys do not appear in the SQL and are only descriptive aliases.

Parameters

string \| string[]	$fields	Name(s) of column(s) with values to compare
string \| int \| float \| string[] \| int[] \| float[]	$values	Values to compare

Returns: mixed

Since: 1.35

Wikimedia\Rdbms\DatabaseSqlite::buildGroupConcatField	(	$delim,
		$table,
		$field,
		$conds = `''`,
		$join_conds = `[]`
	)

Build a GROUP_CONCAT or equivalent statement for a query.This is useful for combining a field for several rows into a single string. NULL values will not appear in the output, duplicated values will appear, and the resulting delimiter-separated values have no defined sort order. Code using the results may need to use the PHP unique() or sort() methods.

Parameters

string	$delim	Glue to bind the results together
string \| array	$table	Table name
string	$field	Field name
string \| array	$conds	Conditions
string \| array	$join_conds	Join conditions

Returns: string SQL text

Build a LEAST function statement comparing columns/values.Integer and float values in $values will not be quotedIf $fields is an array, then each value with a string key is treated as an expression (which must be manually quoted); such string keys do not appear in the SQL and are only descriptive aliases.

Parameters

◆ 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 240 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.

◆ isTransactableQuery()

Wikimedia\Rdbms\DatabaseSqlite::isTransactableQuery ( $sql )

protected

Determine whether a SQL statement is sensitive to isolation level.

A SQL statement is considered transactable if its result could vary depending on the transaction isolation level. Operational commands such as 'SET' and 'SHOW' are not considered to be transactable.

Main purpose: Used by query() to decide whether to begin a transaction before the current query (in DBO_TRX mode, on by default).

Stability: stable: to override

Parameters

string $sql

Returns: bool

Reimplemented from Wikimedia\Rdbms\Database.

◆ isWriteQuery()

Wikimedia\Rdbms\DatabaseSqlite::isWriteQuery	(	$sql,
		$flags
	)

protected

Determine whether a query writes to the DB.

When in doubt, this returns true.

Main use cases:

Subsequent web requests should not need to wait for replication from the primary position seen by this web request, unless this request made changes to the primary DB. This is handled by ChronologyProtector by checking doneWrites() at the end of the request. doneWrites() returns true if any query set lastWriteTime; which query() does based on isWriteQuery().
Reject write queries to replica DBs, in query().

Parameters

string	$sql
int	$flags	Query flags to query()

Returns: bool

◆ 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)
