FBSQL_ERRNO(3)								 1							    FBSQL_ERRNO(3)

fbsql_errno - Returns the error number from previous operation

SYNOPSIS

       int fbsql_errno ([resource  $link_identifier])

DESCRIPTION

	Returns the numerical value of the error message from previous FrontBase operation.

	Errors coming back from the fbsql database backend don't issue warnings. Instead, use fbsql_errno(3) to retrieve the error code. Note that
       this function only returns the error code from the most recently executed fbsql function (not including fbsql_error(3) and fbsql_errno(3)),
       so if you want to use it, make sure you check the value before calling another fbsql function.

PARAMETERS

	      o $
		link_identifier  -A FrontBase link identifier returned by fbsql_connect(3) or fbsql_pconnect(3).If optional and not specified, the
		function will try to find an open link to the FrontBase server and if no such link is found it	will  try  to  create  one  as	if
		fbsql_connect(3) was called with no arguments.

RETURN VALUES

	Returns the error number from the last fbsql function, or 0 (zero) if no error occurred.

EXAMPLES

       Example #1

	      <?php

	      fbsql_select_db("nonexistentdb");
	      echo fbsql_errno() . ": " . fbsql_error() . "<br />";
	      $conn = fbsql_query("SELECT * FROM nonexistenttable;");
	      echo fbsql_errno() . ": " . fbsql_error() . "<br />";

mysql_error - Returns the text of the error message from previous MySQL operation

SYNOPSIS

       Warning

	      This  extension  is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
	      be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

		     omysqli_error(3)

		     o PDO::errorInfo

       string mysql_error ([resource  $link_identifier = NULL])

DESCRIPTION

	Returns the error text from the last MySQL function. Errors coming back from the MySQL database backend no longer issue warnings. Instead,
       use  mysql_error(3)  to	retrieve the error text. Note that this function only returns the error text from the most recently executed MySQL
       function (not including mysql_error(3) and mysql_errno(3)), so if you want to use it, make sure you check the value before calling  another
       MySQL function.

	      o $
		link_identifier  -The  MySQL  connection.  If  the  link  identifier is not specified, the last link opened by mysql_connect(3) is
		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	Returns the error text from the last MySQL function, or '' (empty string) if no error occurred.

       Example #1

	      mysql_error(3) example

	      <?php
	      $link = mysql_connect("localhost", "mysql_user", "mysql_password");

	      mysql_select_db("nonexistentdb", $link);
	      echo mysql_errno($link) . ": " . mysql_error($link). "
";

	      mysql_select_db("kossu", $link);
	      mysql_query("SELECT * FROM nonexistenttable", $link);
	      echo mysql_errno($link) . ": " . mysql_error($link) . "
";
	      ?>

	      The above example will output something similar to:

	      1049: Unknown database 'nonexistentdb'
	      1146: Table 'kossu.nonexistenttable' doesn't exist
