Inherited Methods

Class: DB_common

DB_common::DB_common(): Constructor
DB_common::affectedRows(): returns the affected rows of a query
DB_common::autoCommit(): enable automatic Commit
DB_common::autoExecute(): Make automaticaly an insert or update query and call prepare() and execute() with it
DB_common::autoPrepare(): Make automaticaly an insert or update query and call prepare() with it
DB_common::buildManipSQL(): Make automaticaly an sql query for prepare()
DB_common::commit(): starts a Commit
DB_common::createSequence(): creates a new sequence
DB_common::dropSequence(): deletes a sequence
DB_common::errorCode(): Map native error codes to DB's portable ones. Requires that the DB implementation's constructor fills in the $errorcode_map property.
DB_common::errorMessage(): Map a DB error code to a textual message. This is actually just a wrapper for DB::errorMessage().
DB_common::errorNative(): returns an errormessage, provides by the database
DB_common::execute(): Executes a prepared SQL query
DB_common::executeMultiple(): This function does several execute() calls on the same statement handle. $data must be an array indexed numerically from 0, one execute call is done for every "row" in the array.
DB_common::getAll(): Fetch all the rows returned from a query.
DB_common::getAssoc(): Fetch the entire result set of a query and return it as an associative array using the first column as the key.
DB_common::getCol(): Fetch a single column from a result set and return it as an indexed array.
DB_common::getListOf(): list internal DB info valid values for $type are db dependent, often: databases, users, view, functions
DB_common::getOne(): Fetch the first column of the first row of data returned from a query. Takes care of doing the query and freeing the results when finished.
DB_common::getOption(): returns the value of an option
DB_common::getRow(): Fetch the first row of data returned from a query. Takes care of doing the query and freeing the results when finished.
DB_common::getSequenceName()
DB_common::getTables()
DB_common::limitQuery(): Generates a limited query
DB_common::nextId(): returns the next free id of a sequence
DB_common::numRows(): returns the number of rows in a result object
DB_common::prepare(): Prepares a query for multiple execution with execute().
DB_common::provides(): Tell whether a DB implementation or its backend extension supports a given feature.
DB_common::query(): Send a query to the database and return any results with a DB_result object.
DB_common::quote(): Quotes a string so it can be safely used in a query. It will return the string with single quotes around. Other backend quote styles should override this method.
DB_common::quoteString(): Quotes a string so it can be safely used within string delimiters in a query (preserved for compatibility issues, quote() is preffered).
DB_common::raiseError(): This method is used to communicate an error and invoke error callbacks etc. Basically a wrapper for PEAR::raiseError without the message string.
DB_common::rollback(): starts a rollback
DB_common::setFetchMode(): Sets which fetch mode should be used by default on queries on this connection.
DB_common::setOption(): set the option for the db class
DB_common::tableInfo(): returns meta data about the result set

Method Detail

DB_ifx (Constructor) [line 47]

DB_ifx DB_ifx(
)

[ Top ]

affectedRows [line 178]

number affectedRows(
)

Gets the number of rows affected by the last query.

if the last query was a select, returns an _estimate_ value.

Return: of rows affected by the last query

Overrides DB_common::affectedRows() (returns the affected rows of a query)

connect [line 82]

int connect(
$dsn
&$dsninfo, [$persistent
$persistent = false])

Connect to a database and log in as the specified user.

Return: DB_OK on success, a DB error code on failure

Parameters:

$dsn	`&$dsninfo`	—	the data source name (see DB::parseDSN for syntax)
$persistent	`$persistent`	—	(optional) whether the connection should be persistent

disconnect [line 109]

bool disconnect(
)

Log out and disconnect from the database.

Return: TRUE on success, FALSE if not connected.

[ Top ]

errorCode [line 312]

int errorCode(
mixed
$nativecode)

Map native error codes to DB's portable ones. Requires that the DB implementation's constructor fills in the $errorcode_map property.

Return: a portable DB error code, or DB_ERROR if this DB implementation has no mapping for the given error code.

Overrides DB_common::errorCode() (Map native error codes to DB's portable ones. Requires that the DB implementation's constructor fills in the $errorcode_map property.)

errorNative [line 331]

int errorNative(
)

Get the native error message of the last error (if any) that occured on the current connection.

Return: native Informix error code

Overrides DB_common::errorNative() (returns an errormessage, provides by the database)

fetchInto [line 218]

int fetchInto(
$result
$result, $row
&$row, $fetchmode
$fetchmode, [$rownum
$rownum = null])

Fetch a row and return as array.

Return: an array on success, a DB error code on failure, NULL if there is no more data

Parameters:

$result	`$result`	—	Informix result identifier
$row	`&$row`	—	(reference) array where data from the row is stored
$fetchmode	`$fetchmode`	—	how the resulting array should be indexed

array fetchRow(
$result
$result, [$fetchmode
$fetchmode = DB_FETCHMODE_DEFAULT], [$rownum
