    <p>I'm writing a linq query and I've run into trouble with it so I was wondering if someone could help. Here is a bit of background:</p> <p>I didn't design the database so the structure cannot be changed. So I have the Main 'Game' table, which has a main product code, A foreign key in this table is GameDataID from the GameData table which contains information such as release dates, released by, etc. Then I have the GameFormat table, which contains the product codes for the game in each format, e.g. Mac, Windows, etc and again the GameDataID is a foreign key. See Below.</p> <pre><code>Game GameID PK MainGameProductCode MainGameTitle GameDataID FK GameData GameDataID PK GameReleaseDate GameReleasedBy GameFormat GameFormatID PK GameDataID FK GameFormatProductcode </code></pre> <p>So when sales reports are received back, some only contain 'GameFormatProductCode' as the product identifier. So from 'GameFormatProductCode' I need to retrieve the 'GameID' in the main Game table. </p> <p>So far I have written the linq query to retrieve the GameFormatProductcode from the GameFormat table, however I am unsure how to go about retrieving the GameID from the main Game table.</p> <pre><code>private Int64 GetGameID(string gameFormatProductCode) { ModelCtn ctn = new ModelCtn(); Game game = null; GameFormat gf = null; gf = (from t in ctn.GameFormat where t.GameFormatProductcode == gameFormatProductCode select t).FirstOrDefault(); // Need to find GameID from Game table and return it. return gf; } </code></pre> <p>Any linq experts out there care to point me in the right direction? Very new to Linq so be gentle :)</p>

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.
