Detailed Description

RecordSet class that represents the dataset returned by the database. To keep memory overhead low, this class holds only the current row in memory. No prefetching of data is done, so the RecordCount() can return -1 ( which means recordcount not known).

ADORecordSet::GetMenu	(	$	name,
		$	defstr = '',
		$	blank1stItem = true,
		$	multiple = false,
		$	size = 0,
		$	selectAttr = '',
		$	compareFields0 = true
	)

Generate a SELECT tag string from a recordset, and return the string. If the recordset has 2 cols, we treat the 1st col as the containing the text to display to the user, and 2nd col as the return value. Default strings are compared with the FIRST column.

Parameters:

	name	name of SELECT tag
	[defstr]	the value to hilite. Use an array for multiple hilites for listbox.
	[blank1stItem]	true to leave the 1st item in list empty
	[multiple]	true for listbox, false for popup
	[size]	rows to show for listbox. not used by popup
	[selectAttr]	additional attributes to defined for SELECT tag. useful for holding javascript onChange='...' handlers. &
	[compareFields0]	when we have 2 cols in recordset, we compare the defstr with column 0 (1st col) if this is true. This is not documented.

Returns:

HTML

& ADORecordSet::GetArray

(

$

nRows = -1

)

return recordset as a 2-dimensional array.

Parameters:

[nRows]

is the number of rows to return. -1 means every row.

Returns:

an array indexed by the rows (0-based) from the recordset

Reimplemented in ADORecordSet_array.

& ADORecordSet::GetArrayLimit	(	$	nrows,
		$	offset = -1
	)

return recordset as a 2-dimensional array. Helper function for ADOConnection->SelectLimit()

Parameters:

	offset	is the row to start calculations from (1-based)
	[nrows]	is the number of rows to return

Returns:

an array indexed by the rows (0-based) from the recordset

Reimplemented in ADORecordSet_db2, ADORecordset_oci8, ADORecordset_oci8po, and ADORecordSet_odbc.

& ADORecordSet::GetRows

(

$

nRows = -1

)

Synonym for GetArray() for compatibility with ADO.

Parameters:

[nRows]

is the number of rows to return. -1 means every row.

Returns:

an array indexed by the rows (0-based) from the recordset

Definition at line 2910 of file adodb.inc.php.

References GetArray().

& ADORecordSet::GetAssoc	(	$	force_array = false,
		$	first2cols = false
	)

return whole recordset as a 2-dimensional associative array if there are more than 2 columns. The first column is treated as the key and is not included in the array. If there is only 2 columns, it will return a 1 dimensional array of key-value pairs unless $force_array == true.

Parameters:

	[force_array]	has only meaning if we have 2 data columns. If false, a 1 dimensional array is returned, otherwise a 2 dimensional array is returned. If this sounds confusing, read the source.
	[first2cols]	means if there are more than 2 cols, ignore the remaining cols and instead of returning array[col0] => array(remaining cols), return array[col0] => col1

Returns:

an associative array indexed by the first column of the array, or false if the data has less than 2 cols.

ADORecordSet::MetaType	(	$	t,
		$	len = -1,
		$	fieldobj = false
	)

Get the metatype of the column. This is used for formatting. This is because many databases use different names for the same type, so we transform the original type to our standardised version which uses 1 character codes:

Parameters:

	t	is the type passed in. Normally is ADOFieldObject->type.
	len	is the maximum length of that field. This is because we treat character fields bigger than a certain size as a 'B' (blob).
	fieldobj	is the field object returned by the database driver. Can hold additional info (eg. primary_key for mysql).

Returns:

the general type of the data: C for character < 250 chars X for teXt (>= 250 chars) B for Binary N for numeric or floating point D for date T for timestamp L for logical/Boolean I for integer R for autoincrement counter/integer
