Member Function Documentation

ADODB_sqlite::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 47 of file adodb-sqlite.inc.php.

ADODB_sqlite::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.

Definition at line 55 of file adodb-sqlite.inc.php.

References ADOConnection::Execute().

ADODB_sqlite::CommitTrans

(

$

ok = true

)

If database does not support transactions, always return true as data always commited

Parameters:

$ok

set to false to rollback transaction, true to commit

Returns:

true/false.

Reimplemented from ADOConnection.

Definition at line 63 of file adodb-sqlite.inc.php.

References ADOConnection::Execute(), and RollbackTrans().

ADODB_sqlite::RollbackTrans

(

)

If database does not support transactions, rollbacks always fail, so return false

Returns:

true/false.

Reimplemented from ADOConnection.

Definition at line 72 of file adodb-sqlite.inc.php.

References ADOConnection::Execute().

Referenced by CommitTrans().

ADODB_sqlite::ErrorMsg

(

)

Returns:

the last error message

Reimplemented from ADOConnection.

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

ADODB_sqlite::ErrorNo

(

)

Returns:

the last error number. Normally 0 means no error.

Reimplemented from ADOConnection.

Definition at line 139 of file adodb-sqlite.inc.php.

& ADODB_sqlite::SelectLimit	(	$	sql,
		$	nrows = -1,
		$	offset = -1,
		$	inputarr = false,
		$	secs2cache = 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 193 of file adodb-sqlite.inc.php.

References ADOConnection::CacheExecute(), and ADOConnection::Execute().

ADODB_sqlite::GenID	(	$	seq = 'adodbseq',
		$	start = 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 213 of file adodb-sqlite.inc.php.

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

& ADODB_sqlite::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 264 of file adodb-sqlite.inc.php.
