Request for Multiple Table Options (XMLSchema 03).

Paul Kirby — Sun, 14 Jun 2009 15:12:19 -0000

Hello John

I am one of the Main Developers to Blacknova Traders and i was wondering is
there any chance in ADODB supporting multiple Table options example shown
below:

<?xml version="1.0"?>
<schema version="0.3">
<table name="tablename">

<opt name="engine">InnoDB</opt>
<opt name="comment">This is an example Table</opt>
<field name="field1" type="I4"><key/><autoincrement/></field>
<field name="field_desc" type="C" size="30"></field>
<field name="field2" type="I4"><notnull/><default value="0"/></field>
<index name="field1"><col>field1</col></index>
<index name="field2"><col>field2</col></index>
</table>
</schema>

I am trying to set the Engine Type and also add a Comment to the Table and
for me to do this at the moment I have to use the following line:
<table name="tablename">
<opt>ENGINE="InnoDB", COMMENT="This is an example Table"</opt>
...

Or am I missing somthing?

Thanks in advance

error using mysql5 and reserved word

Anonymous — Tue, 05 May 2009 12:56:59 -0000

using mysql5 if the field of the table has a reserved name, the "adodb-active" generates an error.

Example using the reserved word "sql" as name of a field:
CREATE TABLE `chartsql` (
`seqno` int(11) NOT NULL default '0',
`sql` text NOT NULL
);
INSERT INTO (seqno, sql) VALUES(1, "SELECT 1 + 1"); <--- ERRO!!!
INSERT INTO (`seqno`, `sql`) VALUES(1, "SELECT 1 + 1"); <--- OK!!!

Solution: Add "` " to the name of the field;

adodo-active-record.inc.php, line 507 (adodb version V4.990):
$sql = 'INSERT INTO '.$this->_table."(`".implode('`,`',$names).'`) VALUES ('.implode(',',$valstr).')';

adodo-active-record.inc.php, line 651 (adodb version V4.990):
$pairs[] = "`$name` = " . $db->Param($cnt);

Limit DB Connections / Connect on Demand

spcmky — Tue, 13 Nov 2007 15:20:27 -0000

I would like to request that connections to the database are not created unless there is a need. In a website application, for example, if all the queries for a page a re cached then there is no need to connect to the database. This would provide a significant performance boost by eliminating connection latency and freeing up system resources. After reviewing the code it is my belief that there could be a check put in place in a few functions that would test to see if a connection is established and to create one if not. These checks would go into the execute and prepare functions. I've tested this concept out and the benefit is tremendous. I've had it running in a production environment for months now with no issues. I serve ~50 million page views a day so this has been properly abused.

Prepared statements for MySQLi driver

Tue, 19 Jun 2007 10:36:27 -0000

It would be nice to make use of prepared
statements in the mysqli driver (the PHP ext supports this).
Currently Perpare() only returns the SQL-statement and does not prepare it.

Auto fetch blob option

Anonymous — Tue, 03 Apr 2007 21:41:13 -0000

Example: I have a table with a blob field that have 4mb, the table have 30 records = 1mb x 100 = 100mb, but I need to fetch only some blobs that some condition.

I using FirebirdSQL with ibase_* php function, and blob I fetch when I need.

It's a usefull ADORecordSet option "AutoFetchBlob", and use ADOConnection->BlobDecode(ADORecordSet->blob_field)
but with ADO firebird/ibase don't work...

Can you improve that...
Thanks

Supress mysqli connection warning (useful for caching)

Rene — Mon, 05 Mar 2007 10:35:10 -0000

May I suggest and very small fix to the mysqli driver:
Line 108:

$ok = @mysqli_real_connect($this->_connectionID, ...

I just added the @ in front of the mysqli_real_connect .. to supress connection warnings.

Why would I do this - simple:
When ALL your queries are cached (1h) -> you can shutdown the database server and your site still stays online (readonly).

Renaming columns

Anonymous — Thu, 05 Oct 2006 08:23:16 -0000

For mysql I have to use the function RenameColumnSQL
with a full column definition. But I can't understand
this. mysql supports the ALTER table RENAME old_name
new_name syntax. Why it isn't used by this funtion in
the data dictionary?

Regexp - Operator

Anonymous — Thu, 05 Oct 2006 08:19:46 -0000

I'd like to have a posibility to use regular
expressions in sql queries.
at the moment I use adodb with mysql and postgresql. I
have to use the operator REGEXP (or RLIKE) in mysql and
SIMILAR TO (or ~*) in postgres. so I have to replace
the RLIKE in my queries manually with ~* for postgres.
Is there a way zo use one function or something like
this in adodb to get this feature?
