Constructor & Destructor Documentation

DatabaseOracle::__construct ( params = null)

Constructor.

FIXME: It is possible to construct a Database object with no associated connection object, by specifying no parameters to __construct(). This feature is deprecated and should be removed.

DatabaseBase subclasses should not be constructed directly in external code. DatabaseBase::factory() should be used instead.

Parameters:
array$paramsParameters passed from DatabaseBase::factory()

Reimplemented from DatabaseBase.

Definition at line 203 of file DatabaseOracle.php.

Run a few simple sanity checks.

Reimplemented from DatabaseBase.

Definition at line 228 of file DatabaseOracle.php.


Member Function Documentation

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 DatabaseMysql.

Parameters:
string$s
Returns:
string

Reimplemented from DatabaseBase.

Definition at line 1288 of file DatabaseOracle.php.

References $s.

Adds quotes and backslashes.

Parameters:
string$s
Returns:
string

Reimplemented from DatabaseBase.

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:
string$tableTable name. This will be passed through DatabaseBase::tableName().
array$aArray of rows to insert
string$fnameCalling function name (use __METHOD__) for logs/profiling
array$optionsArray of options
Returns:
bool

)

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

Parameters:

string | array$srcTableMay be either a table name, or an array of table names to include in a join.
array$varMapMust 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$condsCondition array. See $conds in DatabaseBase::select() for the details of the format of condition arrays. May be "*" to copy the whole table.
string$fnameThe function name of the caller, from __METHOD__
array$insertOptionsOptions for the INSERT part of the query, see DatabaseBase::insert() for details.

References $res.

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$sqlSQL query we will append the limit too
int$limitThe SQL limit
int | bool$offsetThe SQL offset (default false)
Exceptions:
DBUnexpectedError
Returns:
string

Reimplemented from DatabaseBase.

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$nameDatabase table name
string$formatOne 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

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:
string | int$ts
Returns:
string

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$tableTable name. This will be passed through DatabaseBase::tableName().
array$rowsA single row or list of rows to insert
array$uniqueIndexesList of single field names or field name tuples
array$setAn 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$fnameCalling function name (use __METHOD__) for logs/profiling
Exceptions:
Exception
Returns:
bool
