Constructor & Destructor Documentation

◆ __construct()

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

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$p

Member Function Documentation

◆ addQuotes()

◆ attachDatabase()

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

Attaches external database to our connection, see https://sqlite.org/lang_attach.html for details.

Parameters
string$nameDatabase name to be used in queries like SELECT foo FROM dbname.table
bool | string$fileDatabase file name. If omitted, will be generated using $name and configured data directory
string$fnameCalling function name
Returns
IResultWrapper

Definition at line 304 of file DatabaseSqlite.php.

◆ buildConcat()

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

Build a concatenation list to feed into a SQL query.

Parameters
string[]$stringList
Returns
string

Implements Wikimedia\Rdbms\IDatabase.

Definition at line 1002 of file DatabaseSqlite.php.

◆ buildGroupConcatField()

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$delimGlue to bind the results together
string | array$tableTable name
string$fieldField name
string | array$condsConditions
string | array$join_condsJoin conditions
Returns
string SQL text

◆ buildSubstring()

Wikimedia\Rdbms\DatabaseSqlite::buildSubstring (   $input,

)

◆ closeConnection()

Wikimedia\Rdbms\DatabaseSqlite::closeConnection ( )
protected

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

Returns
bool

Definition at line 219 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 fully separate, only allowing mechanisms like postgres_fdw to effectively "mount" foreign DBs. This is true even among DBs on the same server.

Returns
bool
