Mysql CHAR vs VARCHAR

Looking for any advise from a DBA/DA. When should you use CHAR and when should you use VARCHAR when designing a table. From my readings seems like VARCHAR will accept any length string even though you define a length to it, so I setup gadget VARCHAR(10) I could actually put something with 20 characters in there. Thanks for any advise on this. Bill

MAXDB_SQLSTATE(3)							 1							 MAXDB_SQLSTATE(3)

maxdb_sqlstate - Returns the SQLSTATE error from previous MaxDB operation

       Procedural style

SYNOPSIS
string maxdb_sqlstate (resource $link) DESCRIPTION
Object oriented style string$maxdb->sqlstate () Returns a string containing the SQLSTATE error code for the last error. The error code consists of five characters. '00000' means no error. The values are specified by ANSI SQL and ODBC. Note Note that not all MaxDB errors are yet mapped to SQLSTATE's. The value HY000 (general error) is used for unmapped errors. RETURN VALUES
Returns a string containing the SQLSTATE error code for the last error. The error code consists of five characters. '00000' means no error. EXAMPLES
Example #1 Object oriented style <?php $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* Table City already exists, so we should get an error */ if (!$maxdb->query("CREATE TABLE hotel.city (ID INT, Name VARCHAR(30))")) { printf("Error - SQLSTATE %s. ", $maxdb->sqlstate); } $maxdb->close(); ?> Example #2 Procedural style <?php $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB"); /* check connection */ if (maxdb_connect_errno()) { printf("Connect failed: %s ", maxdb_connect_error()); exit(); } /* Table City already exists, so we should get an error */ if (!maxdb_query($link, "CREATE TABLE hotel.city (ID INT, Name VARCHAR(30))")) { printf("Error - SQLSTATE %s. ", maxdb_sqlstate($link)); } maxdb_close($link); ?> The above example will output something similar to: Warning: maxdb_query(): -6000 POS(20) Duplicate table name:CITY [I6000] <...> Error - SQLSTATE I6000.
