ibase_query - Execute a query on an InterBase database

SYNOPSIS

       resource ibase_query ([resource	$link_identifier], string  $query, [int  $bind_args])

DESCRIPTION

	Performs a query on an InterBase database.

PARAMETERS

	      o $link_identifier
		- An InterBase link identifier. If omitted, the last opened link is assumed.

	      o $query
		- An InterBase query.

	      o $bind_args
		-

RETURN VALUES

	If the query raises an error, returns FALSE. If it is successful and there is a (possibly empty) result set (such as with a SELECT query),
       returns a result identifier. If the query was successful and there were no results, returns TRUE.

       Note

	       In PHP 5.0.0 and up, this function will return the number of rows affected by the query for INSERT, UPDATE and  DELETE  statements.
	      In  order  to  retain  backward compatibility, it will return TRUE for these statements if the query succeeded without affecting any
	      rows.

ERRORS
/EXCEPTIONS
	If you get some error like "arithmetic exception, numeric overflow, or string truncation. Cannot transliterate character between character
       sets"  (this  occurs  when you try use some character with accents) when using this and after ibase_query(3) you must set the character set
       (i.e. ISO8859_1 or your current character set).

mysql_query - Send a MySQL query

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_query(3)

		     o PDO::query

       mixed mysql_query (string  $query, [resource  $link_identifier = NULL])

DESCRIPTION

       mysql_query(3) sends a unique query (multiple queries are not supported) to the currently active database on the server	that's	associated
       with the specified $link_identifier.

	      o $query
		- An SQL query	The query string should not end with a semicolon. Data inside the query should be properly escaped.

	      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.

	For  SELECT,  SHOW,  DESCRIBE, EXPLAIN and other statements returning resultset, mysql_query(3) returns a resource on success, or FALSE on
       error.

	For other type of SQL statements, INSERT, UPDATE, DELETE, DROP, etc, mysql_query(3) returns TRUE on success or FALSE on error.

	The returned result resource should be passed to mysql_fetch_array(3), and other functions for dealing with result tables, to  access  the
       returned data.

	Use  mysql_num_rows(3)	to find out how many rows were returned for a SELECT statement or mysql_affected_rows(3) to find out how many rows
       were affected by a DELETE, INSERT, REPLACE, or UPDATE statement.

       mysql_query(3) will also fail and return FALSE if the user does not have permission to access the table(s) referenced by the query.

       Example #1

	      Invalid Query

	       The following query is syntactically invalid, so mysql_query(3) fails and returns FALSE.

	      <?php
	      $result = mysql_query('SELECT * WHERE 1=1');
	      if (!$result) {
		  die('Invalid query: ' . mysql_error());
	      }

	      ?>

       Example #2

	      Valid Query

	       The following query is valid, so mysql_query(3) returns a resource.

	      <?php
	      // This could be supplied by a user, for example
	      $firstname = 'fred';
	      $lastname  = 'fox';

	      // Formulate Query
	      // This is the best way to perform an SQL query
	      // For more examples, see mysql_real_escape_string()
	      $query = sprintf("SELECT firstname, lastname, address, age FROM friends
		  WHERE firstname='%s' AND lastname='%s'",
		  mysql_real_escape_string($firstname),
		  mysql_real_escape_string($lastname));

	      // Perform Query
	      $result = mysql_query($query);

	      // Check result
	      // This shows the actual query sent to MySQL, and the error. Useful for debugging.
	      if (!$result) {
		  $message  = 'Invalid query: ' . mysql_error() . "
";
		  $message .= 'Whole query: ' . $query;
		  die($message);
	      }

	      // Use result
	      // Attempting to print $result won't allow access to information in the resource
	      // One of the mysql result functions must be used
	      // See also mysql_result(), mysql_fetch_array(), mysql_fetch_row(), etc.
	      while ($row = mysql_fetch_assoc($result)) {
		  echo $row['firstname'];
		  echo $row['lastname'];
		  echo $row['address'];
		  echo $row['age'];
	      }

	      // Free the resources associated with the result set
	      // This is done automatically at the end of the script
	      mysql_free_result($result);
	      ?>
