Customizing select for dataviewgrid

开发者 https://www.devze.com 2023-02-18 09:45 出处:网络
I have a table \"events\" that has the following fields: id, id_client, data_field. The id_client makes a reference to a table \"clients\" that has the following fields: id, name.

I have a table "events" that has the following fields: id, id_client, data_field.

The id_client makes a reference to a table "clients" that has the following fields: id, name.

I would like to display in my dataviewgrid the da开发者_Python百科ta_field and the name of my id_client (from the "clients" table).

How can I make a sql statement so that I may fill my dataview with the apropriate data?

(Note that my data_field is actually a lot of fields, but I only named data_field for convenience in explaining.)


You mean like this?:

SELECT events.id, clients.name, events.data_field
FROM events
  INNER JOIN clients ON events.id_client = clients.id

This will retrieve all events with their id, the name of the associated client, and the data_field.

(Additionally, if for a given events record there isn't always a corresponding clients record then you can replace INNER JOIN with LEFT OUTER JOIN.)
