create table via stored procedure (passing the table name to it)
hi there, I am trying to create a stored procedure that i can pass the table name to and it will create a table with that name. but for some reason it creates with what i have defined as the variable name . In the case of the example below it creates a table called 'tname'

for example


Code:
CREATE PROCEDURE createtable(tname varchar(20))
BEGIN
DROP TABLE IF EXISTS tname;
CREATE TABLE tname SELECT * FROM anothertable WHERE value = 'something';
END //

now i call it passing my desired table name


Code:
mysql> call createtable(accounts);

It works fine apart from the fact it ignores my desired table name of 'accounts' and instead creates a table called 'tname'

Is there something basic i'm doing wrong here?

any help would be greatly appreciated
Cheers

drop_table

DROP 
TABLE(7)							   SQL Commands 						     DROP TABLE(7)

NAME

       DROP TABLE - remove a table

SYNOPSIS

       DROP TABLE [ IF EXISTS ] name [, ...] [ CASCADE | RESTRICT ]

DESCRIPTION

       DROP  TABLE  removes tables from the database.  Only its owner can drop a table. To empty a table of rows without destroying the table, use
       DELETE [delete(7)] or TRUNCATE [truncate(7)].

       DROP TABLE always removes any indexes, rules, triggers, and constraints that exist for the target table.  However, to drop a table that	is
       referenced  by  a  view	or  a  foreign-key  constraint	of another table, CASCADE must be specified. (CASCADE will remove a dependent view
       entirely, but in the foreign-key case it will only remove the foreign-key constraint, not the other table entirely.)

PARAMETERS

       IF EXISTS
	      Do not throw an error if the table does not exist. A notice is issued in this case.

       name   The name (optionally schema-qualified) of the table to drop.

       CASCADE
	      Automatically drop objects that depend on the table (such as views).

       RESTRICT
	      Refuse to drop the table if any objects depend on it. This is the default.

EXAMPLES

       To destroy two tables, films and distributors:

       DROP TABLE films, distributors;

COMPATIBILITY

       This command conforms to the SQL standard, except that the standard only allows one table to be dropped per command, and apart from the	IF
       EXISTS option, which is a PostgreSQL extension.
