my understanding is that Namespace is a defined grouping of classes http://m5.eecs.umich.edu/docs/namespaceMySQL.html
where MySQL triggers a namespace must be unique within the schema (database). http://markmail.org/message/m5icpi2luv6baijt?q="Joerg+Bruehe"+AND+"namespace "+AND+"definition"&page=1&refer=tpuhsicnt5h5helm Buena Suerte/Viel Gluck Martin ----- Original Message ----- From: "Garris, Nicole" <[EMAIL PROTECTED]> To: <mysql@lists.mysql.com> Sent: Wednesday, March 05, 2008 10:33 AM Subject: Re: what is a schema? what is a database? Sorry. An example of a fully qualified SQL Server object name is: SELECT * FROM Server123.Database456.Sales.Product The object Server123.Database456.Manufacture.Product is a different table from Server123.Database456.Sales.Product. Joerg Bruehe in his post called a "schema" a "namespace", I believe he is correct. -----Original Message----- From: news [mailto:[EMAIL PROTECTED] On Behalf Of Thufir Sent: Wednesday, March 05, 2008 3:09 AM To: mysql@lists.mysql.com Subject: Re: FW: Re: what is a schema? what is a database?

In your two examples: SELECT * FROM server.sales.schema.product; SELECT * FROM server.product.schema.product; I'm a bit tired, so maybe I'm not seeing it, but what goes in the schema place holder? -Thufir -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
