    <p>I am trying to finish an sql query and whilst I have found similar problems solved, I cannot get mine to work.</p> <p>I have two tables, orders and cars (there are more fields but these are the ones I am having trouble with:</p> <p>table_cars<br>------------------<br> ID&nbsp;&nbsp; Title<br></p> <p>1 &nbsp;&nbsp;&nbsp; Blue car <br> 2 &nbsp;&nbsp;&nbsp; Red Car<br> 3 &nbsp;&nbsp;&nbsp; Green Car</p> <p>table_orders<br>-----------------<br> Vehicletype<br></p> <p>2 <br> 2 <br> 1 <br> 3 <br> 1 <br> 2 <br></p> <p>So I have the following code, but what I need is the correct inner join syntax to replace the output of vehicle type from the ID to the title as defined in the cars table, so instead of saying '2' it will say 'red car'</p> <p>Here is what I have for the select query:</p> <pre><code>SELECT names, phone, cprice, vehicletype FROM table_orders WHERE driver_id = {$UserId} </code></pre> <p>The results are already filtered on driver_id.</p> <p>Thanks in advance for any help :)</p> <p>--------------------------Continued-----------------------------------------------</p> <p>Apologies, I did get it to work I was missing the 's' after the table name.You seem very smart so I am going to ask another question if that is ok. Here is my full query so far which I know is messy! I am going to use 2 more inner joins to apply the same solution to the 'state' and 'payment' fields (can I have 3?) but my question is on the UNIXTIME fields.</p> <p>The data is stored like 1384380000 in the table so I have to use the UNIXTIME with formatting to get the data to display how I want it. What I want though is the 'datetime2' field will sometimes be empty, so I want to it return either a blank field or a zero if it is empty as currently it returns a date and time like 01/01/70 01:00:00.</p> <pre><code>SELECT s.names, s.phone, IF(s.returntrip=0, 'No', 'Yes'), s.cprice, s.prepay, s.selpassengers, tc.title AS Vehicle, s.selinfantseats, s.selchildseats, s.selboosterseats, s.selluggage, s.selcarry, s.PickupAddr1, s.PickupAddr4, FROM_UNIXTIME(datetime1,'%d/%m/%y %T'), FROM_UNIXTIME(datetime2,'%d/%m/%y %T'), s.message, s.begin, s.end, (CASE WHEN state = '1' THEN 'Accepted' WHEN state = '-2' THEN 'Waiting' WHEN state = '-1' THEN 'Archived' WHEN state = '0' THEN 'Rejected' ELSE 'Unknown' END) AS Status, (CASE WHEN payment = '4' THEN 'Cash to Driver' WHEN payment = '5' THEN 'Credit/Debit Card' WHEN payment = '6' THEN 'Credit/Debit Card to Driver' WHEN payment = '7' THEN 'Account' ELSE 'Unknown' END) AS Payment, s.driver_id FROM #__taxibooking_orders s INNER JOIN #__taxibooking_cars tc ON tc.id = s.vehicletype WHERE s.driver_id = {$UserId} </code></pre> <p>Thanks very much indeed :)</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.
