Note that the real name of your database should go in there, not literally
|
||||
'yourdbname'.
|
||||
|
||||
* `db_driver`(enum['DB','MDB2'], default null): You can try changing this to
|
||||
'MDB2' to use the other driver type for DB_DataObject, but note that it
|
||||
breaks the OpenID libraries, which only support PEAR::DB.
|
||||
|
||||
* `type` (enum["mysql", "pgsql"], default 'mysql'): Used for certain
|
||||
database-specific optimization code. Assumes mysql if not set. "mysql"
|
||||
covers MariaDB, Oracle MySQL, mysqli or otherwise.

|
||||
// | Special note concerning code documentation: |
|
||||
// | QuerySim was originally created for use during development of |
|
||||
// | applications built using the Fusebox framework. (www.fusebox.org) |
|
||||
// | Fusebox uses an XML style of documentation called Fusedoc. (Which |
|
||||
// | is admittedly not well suited to documenting classes and functions. |
|
||||
// | This short-coming is being addressed by the Fusebox community.) PEAR |
|
||||
// | uses a Javadoc style of documentation called PHPDoc. (www.phpdoc.de) |
|
||||
// | Since this class extension spans two groups of users, it is asked |
|
||||
// | that the members of each respect the documentation standard of the |
|
||||
// | other. So it is a further requirement that both documentation |
|
||||
// | standards be included and maintained. If assistance is required |
|
||||
// | please contact Alan Richmond. |

I take information and turn it into a recordset that can be accessed

<history author="Bert Dawson" email="bdawson@redbanner.com" type="Update">
|

Extensive revision that is backwardly compatible but eliminates the
|

need for a separate .sim file.
|

</history>
|
||||
<history author="Alan Richmond" email="arichmond@bigfoot.com" type="Create" date="10-July-2002">
|
||||
Rewrote in PHP as an extention to the PEAR DB API.
|
||||
Functions supported:
|
||||
connect, disconnect, query, fetchRow, freeResult,
|
||||
numCols, numRows, getSpecialQuery
|
||||
David Huyck (bombusbee.com) added ability to escape special
|
||||
characters (i.e., delimiters) using a '\'.
|
||||
Extended PEAR DB options[] for adding incoming parameters. Added
|
||||
options: columnDelim, dataDelim, eolDelim
|
||||
</history>
|
||||
<history author="David Huyck" email="b@bombusbee.com" type="Update" date="19-July-2002">
|
||||
Added the ability to set the QuerySim options at runtime.
|
||||
Default options are:
|
||||
'columnDelim' => ',', // Commas split the column names
|
||||
'dataDelim' => '|', // Pipes split the data fields
|
||||
'eolDelim' => chr(13).chr(10) // Carriage returns split the
|
||||
// lines of data
|
||||
Affected functions are:
|
||||
DB_querysim(): set the default options when the
|
||||
constructor method is called
|
||||
_parseQuerySim($query): altered the parsing of lines, column
|
||||
names, and data fields
|
||||
_empty2null: altered the way this function is called
|
||||
to simplify calling it
|
||||
</history>
|
||||
<history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="24-July-2002">
|
||||
Added error catching for malformed QuerySim text.
|
||||
Bug fix _empty2null(): altered version was returning unmodified
|
||||
lineData.
|
||||
Cleanup:
|
||||
PEAR compliant formatting, finished PHPDocs and added 'out' to
|
||||
Fusedoc 'io'.
|
||||
Broke up _parseQuerySim() into _buildResult() and _parseOnDelim()
|
||||
to containerize duplicate parse code.
|
||||
</history>
|
||||
<history author="David Huyck" email="b@bombusbee.com" type="Update" date="25-July-2002">
|
||||
Edited the _buildResult() and _parseOnDelim() functions to improve
|
||||
reliability of special character escaping.
|
||||
Re-introduced a custom setOption() method to throw an error when a
|
||||
person tries to set one of the delimiters to '\'.
|
||||
</history>
|
||||
<history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="27-July-2002">
|
||||
Added '/' delimiter param to preg_quote() in _empty2null() and
|
||||
_parseOnDelim() so '/' can be used as a delimiter.
|
||||
Added error check for columnDelim == eolDelim or dataDelim == eolDelim.
|
||||
Renamed some variables for consistancy.
|
||||
</history>
|
||||
<history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="30-July-2002">
|
||||
Removed protected function _empty2null(). Turns out preg_split()
|
||||
deals with empty elemants by making them zero length strings, just
|
||||
what they ended up being anyway. This should speed things up a little.
|
||||
Affected functions:
|
||||
_parseOnDelim() perform trim on line here, instead of in
|
||||
_empty2null().
|
||||
_buildResult() remove call to _empty2null().
|
||||
_empty2null() removed function.
|
||||
</history>
|
||||
<history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="1-Jan-2003">
|
||||
Ported to PEAR MDB2.
|
||||
Methods supported:
|
||||
connect, query, getColumnNames, numCols, valid, fetch,
|
||||
numRows, free, fetchRow, nextResult, setLimit
|
||||
(inherited).
|
||||
</history>
|
||||
<history
|
||||
Removed array_change_key_case() work around for <4.2.0 in
|
||||
getColumnNames(), found it already done in MDB2/Common.php.
|
||||
</history>
|
||||
<history author="Alan Richmond" email="arichmond@bigfoot.com" type="Update" date="3-Feb-2003">
|
||||
Changed default eolDelim to a *nix file eol, since we're trimming
|
||||
the result anyway, it makes no difference for Windows. Now only
|
||||
Mac file eols should need to be set (and other kinds of chars).

<note author="Alan Richmond">
|

Got WAY too long. See querysim_readme.txt for instructions and some
|

examples.
|
||||
io section only documents elements of DB_result that DB_querysim uses,
|
||||
adds or changes; see MDB2 and MDB2_Driver_Common for more info.
|

io section uses some elements that are not Fusedoc 2.0 compliant:
