It's because varchar(max) has no defined length in character. It was added in sql2005 to accommodate those datatypes that could potentially exceed 8000 characters. Specially that sql2005 have improved it's support to XML data type. As of today, it can accommodate up to 2GB of data. That's why it's not giving you a definite character length.

Hi There, just moved over from SQL Server to mySQL and finding my way about. In SQL Server there was a way of retrieving (and setting) metaproperties for columns and tables. The closest I see to this is the TABLES.table_comment COLUMNS.column_comment fields in the INFORMATION_SCHEMA 'Database'. How do you set these values? Seems like you...

How do you change the order of key columns in a primary key and view the difference between two tables that have the same name? For example, table x has a primary key called pk_x. PK_x contains two key columns x and y in the order 1 and 2 now I want to change it so that columns x and y are 2 and 1. How do I do that?
