    <p>I have a .NET application which allows users to access various databases by providing a connection string and a provider.</p> <p>One of the databases which users want to access is a MySQL database (not mine so I can't change it) where the primary keys are all stored as GUIDs.</p> <p>My application can access records in various tables in that database when using the MySQL ODBC 3.51 Driver.</p> <p>But using exactly the same code (taking into account that ODBC needs a ? in place of a parameter name whereas the .NET connector needs the "@name" syntax), and attempting to read the same records in the same tables but this time with the MySQL .NET Connector (V6.1.3 as well as v6.2.2), then I get the error "Guid should contain 32 digits with 4 dashes ...".</p> <p>Is there something wrong with the .NET Connector, or is there something I need to specify somewhere to make it work?</p>

    1. COhow does the .NET driver know it is a GUID? GUID is not a native MySQL data type, so it cannot've deduced it from the table structure.

    2. COHow is the column containing the guid specified and how does your failing query look like ?

    3. CORoland: That's a good question! I wish I knew the answer. As I said, this isn't my data base it's someone else's, so I'm just issuing a SELECT WHERE id = @paramName call. I only know the id is a GUID because I was able to retrieve the data using the ODBC driver, and when I look at that I see it looks GUID-like.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
