Member Function Documentation

ADODB_mysql::ServerInfo

(

)

Get server version info...

Returns:

An array with 2 elements: $arr['string'] is the description string, and $arr[version] is the version (also a string).

Reimplemented from ADOConnection.

Definition at line 48 of file adodb-mysql.inc.php.

References ADOConnection::_findvers(), and ADOConnection::GetOne().

& ADODB_mysql::MetaTables	(	$	ttype = false,
		$	showSchema = false,
		$	mask = false
	)

Parameters:

	ttype	can either be 'VIEW' or 'TABLE' or false. If false, both views and tables are returned. "VIEW" returns only views "TABLE" returns only tables
	showSchema	returns the schema/user with the table name, eg. USER.TABLE
	mask	is the input mask - only supported by oci8 and postgresql

Returns:

array of tables for current database.

Reimplemented from ADOConnection.

Definition at line 61 of file adodb-mysql.inc.php.

References ADOConnection::MetaTables(), and qstr().

& ADODB_mysql::MetaIndexes	(	$	table,
		$	primary = FALSE,
		$	owner = false
	)

List indexes on a table as an array.

Parameters:

	table	table name to query
	primary	true to only show primary keys. Not actually used for most databases

Returns:

array of indexes on current table. Each element represents an index, and is itself an associative array.

Array ( [name_of_index] => Array ( [unique] => true or false [columns] => Array ( [0] => firstname [1] => lastname ) )

Reimplemented from ADOConnection.

Definition at line 79 of file adodb-mysql.inc.php.

References ADOConnection::$false, ADOConnection::Execute(), and ADOConnection::SetFetchMode().

ADODB_mysql::qstr	(	$	s,
		$	magic_quotes = false
	)

Correctly quotes a string so that all strings are escaped. We prefix and append to the string single-quotes. An example is $db->qstr("Don't bother",magic_quotes_runtime());

Parameters:

	s	the string to quote
	[magic_quotes]	if $s is GET/POST var, set to get_magic_quotes_gpc(). This undoes the stupidity of magic quotes for GPC.

Returns:

quoted string to be sent back to database

Reimplemented from ADOConnection.

Definition at line 133 of file adodb-mysql.inc.php.

Referenced by MetaTables().

ADODB_mysql::GetOne	(	$	sql,
		$	inputarr = false
	)

Return first element of first row of sql statement. Recordset is disposed for you.

Parameters:

	sql	SQL statement
	[inputarr]	input bind array

Reimplemented from ADOConnection.

Definition at line 158 of file adodb-mysql.inc.php.

References ADOConnection::GetOne(), and SelectLimit().

ADODB_mysql::BeginTrans

(

)

Begin a Transaction. Must be followed by CommitTrans() or RollbackTrans().

Returns:

true if succeeded or false if database does not support transactions

Reimplemented from ADOConnection.

Reimplemented in ADODB_mysqlt.

Definition at line 173 of file adodb-mysql.inc.php.

References ADOConnection::outp().

ADODB_mysql::GenID	(	$	seqname = 'adodbseq',
		$	startID = 1
	)

Generates a sequence id and stores it in $this->genID; GenID is only available if $this->hasGenID = true;

Parameters:

	seqname	name of sequence to use
	startID	if sequence does not exist, start at this ID

Returns:

0 if not supported, otherwise a sequence id

Reimplemented from ADOConnection.

Definition at line 201 of file adodb-mysql.inc.php.

References ADOConnection::Execute().

& ADODB_mysql::MetaDatabases

(

)

return the databases that the driver can connect to. Some databases will return an empty array.

Returns:

an array of database names.

Reimplemented from ADOConnection.

Definition at line 226 of file adodb-mysql.inc.php.

ADODB_mysql::SQLDate	(	$	fmt,
		$	col = false
	)

Reimplemented from ADOConnection.

Definition at line 242 of file adodb-mysql.inc.php.

ADODB_mysql::Concat

(

)

Different SQL databases used different methods to combine strings together. This function provides a wrapper.

param s variable number of string parameters

Usage: $db->Concat($str1,$str2);

Returns:

concatenated string

Reimplemented from ADOConnection.

Definition at line 330 of file adodb-mysql.inc.php.

ADODB_mysql::SelectDB

(

$

dbName

)

Choose a database to connect to. Many databases do not support this.

Parameters:

dbName

is the name of the database to select

Returns:

true or false

Reimplemented from ADOConnection.

Definition at line 470 of file adodb-mysql.inc.php.

Referenced by _connect(), _pconnect(), and MetaColumns().

& ADODB_mysql::SelectLimit	(	$	sql,
		$	nrows = -1,
		$	offset = -1,
		$	inputarr = false,
		$	secs = 0
	)

Will select, getting rows from $offset (1-based), for $nrows. This simulates the MySQL "select * from table limit $offset,$nrows" , and the PostgreSQL "select * from table limit $nrows offset $offset". Note that MySQL and PostgreSQL parameter ordering is the opposite of the other. eg. SelectLimit('select * from table',3); will return rows 1 to 3 (1-based) SelectLimit('select * from table',3,2); will return rows 3 to 5 (1-based)

Uses SELECT TOP for Microsoft databases (when $this->hasTop is set) BUG: Currently SelectLimit fails with $sql with LIMIT or TOP clause already set

Parameters:

	sql
	[offset]	is the row to start calculations from (1-based)
	[nrows]	is the number of rows to get
	[inputarr]	array of bind variables
	[secs2cache]	is a private parameter only used by jlim

Returns:

the recordset ($rs->databaseType == 'array')

Reimplemented from ADOConnection.

Definition at line 481 of file adodb-mysql.inc.php.

ADODB_mysql::ErrorMsg

(

)

Returns:

the last error message

Reimplemented from ADOConnection.

Definition at line 504 of file adodb-mysql.inc.php.

ADODB_mysql::ErrorNo

(

)

Returns:

the last error number. Normally 0 means no error.

Reimplemented from ADOConnection.

Definition at line 514 of file adodb-mysql.inc.php.
