SHOW(7) 							   SQL Commands 							   SHOW(7)

NAME

       SHOW - show the value of a run-time parameter

SYNOPSIS

       SHOW name
       SHOW ALL

DESCRIPTION

       SHOW  will  display  the  current  setting of run-time parameters. These variables can be set using the SET statement, by editing the post-
       gresql.conf configuration file, through the PGOPTIONS environmental variable (when using libpq or a libpq-based	application),  or  through
       command-line flags when starting the postgres server. See in the documentation for details.

PARAMETERS

       name   The  name  of  a	run-time  parameter. Available parameters are documented in in the documentation and on the SET [set(7)] reference
	      page. In addition, there are a few parameters that can be shown but not set:

	      SERVER_VERSION
		     Shows the server's version number.

	      SERVER_ENCODING
		     Shows the server-side character set encoding. At present, this parameter can be shown but not set, because  the  encoding	is
		     determined at database creation time.

	      LC_COLLATE
		     Shows  the  database's  locale  setting  for  collation (text ordering). At present, this parameter can be shown but not set,
		     because the setting is determined at database creation time.

	      LC_CTYPE
		     Shows the database's locale setting for character classification. At present, this  parameter  can  be  shown  but  not  set,
		     because the setting is determined at database creation time.

	      IS_SUPERUSER
		     True if the current role has superuser privileges.

       ALL    Show the values of all configuration parameters, with descriptions.

NOTES

       The  function  current_setting  produces  equivalent output; see in the documentation.  Also, the pg_settings system view produces the same
       information.

EXAMPLES

       Show the current setting of the parameter DateStyle:

       SHOW DateStyle;
	DateStyle
       -----------
	ISO, MDY
       (1 row)

       Show the current setting of the parameter geqo:

       SHOW geqo;
	geqo
       ------
	on
       (1 row)

       Show all settings:

       SHOW ALL;
		     name	       |	    setting		|					  description
       --------------------------------+--------------------------------+----------------------------------------------------------------------------------------------
	add_missing_from	       | off				| Automatically adds missing table references to FROM clauses.
	allow_system_table_mods        | off				| Allows modifications of the structure of system tables.
	   .

	   .
	work_mem		       | 1024				| Sets the maximum memory to be used for query workspaces.
	zero_damaged_pages	       | off				| Continues processing past damaged page headers.
       (146 rows)

COMPATIBILITY

       The SHOW command is a PostgreSQL extension.

MYSQL_LIST_TABLES(3)							 1						      MYSQL_LIST_TABLES(3)

mysql_list_tables - List tables in a MySQL database

SYNOPSIS

       Warning

	      This  function  was deprecated in PHP 4.3.0, and will be removed in the future, along with the entirety of the original MySQL exten-
	      sion. 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:

		     oSQL Query:
		       SHOW TABLES FROM sometable

       resource mysql_list_tables (string  $database, [resource  $link_identifier = NULL])

DESCRIPTION

	Retrieves a list of table names from a MySQL database.

	This  function is deprecated. It is preferable to use mysql_query(3) to issue an SQL SHOW TABLES [FROM db_name] [LIKE 'pattern'] statement
       instead.

	      o $database
		- The name of the database

	      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.

	A result pointer resource on success or FALSE on failure.

	Use the mysql_tablename(3) function to traverse this result pointer, or any function for result tables, such as mysql_fetch_array(3).

	      <?php
	      $dbname = 'mysql_dbname';

	      if (!mysql_connect('mysql_host', 'mysql_user', 'mysql_password')) {
		  echo 'Could not connect to mysql';
		  exit;
	      }

	      $sql = "SHOW TABLES FROM $dbname";
	      $result = mysql_query($sql);

	      if (!$result) {
		  echo "DB Error, could not list tables
";
		  echo 'MySQL Error: ' . mysql_error();
		  exit;
	      }

	      while ($row = mysql_fetch_row($result)) {
		  echo "Table: {$row[0]}
";
	      }

	      mysql_free_result($result);
	      ?>

       Note

	       For backward compatibility, the following deprecated alias may be used: mysql_listtables(3)

       mysql_list_dbs(3), mysql_tablename(3).
