Hello! Me Again, have a new thing stumping me.....


we have 2 MySQL systems, a mysql dump is used, coded in PHP to copy data from one server to another server, now when this script was running, it used to copy from Windows to a LInux system, now the LInux system is being replaced temp, with a Windows box, now switching the script to point to this new server when it runs, when it creates the folder on the new windows box, it makes the folder name with a small letter as opposed to a capital (the original soure has a capital A)

Here is the script being used, is there somethign in it thatis making it change the Capital A to a small A? or is this some new setting / restriction in MySQL 5.0.45?

This file is run via a .bat file using php.exe, something that will remain for now so i need to figure out why it is making a small A, i could manually change it every day this run, but would prefer if it could fully work.


<?

	$windows2=mysql_connect("****************","********","********");

	$windows=mysql_connect("****************","********","********");

	$dbwbases=mysql_query("show databases", $windows);

	$dblbases=mysql_query("show databases",$windows2);

	$windows2bases=array();

	$windowsbases=array();

	while ($lbases=mysql_fetch_row($dblbases))

	{	

		array_push($windows2bases,$lbases[0]);

	

	}

	

	while ($wbases=mysql_fetch_row($dbwbases))

	{

		

		if (($wbases[0]<>"mysql") and ($wbases[0]>'Archive-2005-11-28-04-31'))

		{

			

			//$Archivename=substr($wbases[0],0,7).substr($wbases[0],8,4).substr($wbases[0],13,2).substr($wbases[0],16,2).substr($wbases[0],19,2).substr($wbases[0],22,2).substr($wbases[0],25,2);

	}

	/* $diffbases=array_diff($windows2bases,$windowsbases);

	$db_list = mysql_list_dbs($windows2);

	while ($database=mysql_fetch_object($db_list))

	{

		$dbase=$database->Database;

		if (strlen($dbase)>18)

			{$realdbase=$dbase;} 

			//get the latest Archive name

	}

	//exec("mysqldump --opt -h **************** --user=******** $realdbase | mysql --host=**************** --user=outside -C ********");

mysql databases on windows boxes do not use upper case. create a database called "MyBase" in phpMyAdmin on Windows, and you will see what I mean

is there any way to remove that auto feature? daily we extract archived files and we use a Capital A and have for about 6 years now, some scripts are written to look for the spefic name, and if i read MySQL site right, certain things are case sensitive.. on windows?


Just found this


Use lower_case_table_names=0 on Unix and lower_case_table_names=2 on Windows. This preserves the lettercase of database and table names. The disadvantage of this is that you must ensure that your statements always refer to your database and table names with the correct lettercase on Windows. If you transfer your statements to Unix, where lettercase is significant, they do not work if the lettercase is incorrect.
