  • Returning Null values with COUNT

    - by Randy B.
    With this query, I get a result that is two short of the table because they are not included in count, and I would like get the NULL values in the result. To do this, I am pretty sure I need to use a subquery of some kind, but I am not sure how, since the attribute in question is an aggregate. SELECT Equipment.SerialNo , Name, COUNT(Assignment.SerialNo) FROM Equipment INNER JOIN Assignment ON Assignment.SerialNo = Equipment.SerialNo GROUP BY Equipment.SerialNo, Name

  • Use subform record set as domain argument in DAvg()

    - by harto
    Is it possible to use a subform's 'current' record set as the domain argument to DAvg() (etc.)? Basically, I have a subform that displays a subset of records from a query. I would like to run DAvg() over this subset. This is how I've gotten around it: =DAvg([FieldToAvg], [SubformQuery], "ChildField=Forms.MasterForm.MasterField And FieldToAvg > 0") but what I actually want is something like: =DAvg([FieldToAvg], [SubformCurrentlyDisplayedData], "FieldToAvg > 0") Is this possible in Access 2007?

  • MySQL: how to index an "OR" clause

    - by JoséMi
    I'm executing the following query SELECT COUNT(*) FROM table WHERE field1='value' AND (field2 = 1000 OR field3 = 2000) There is one index over field1 and another composited over field2&field3. I see MySQL always selects the field1 index and then makes a join using the other two fields which is quite bad because it needs to join 146.000 rows. Suggestions on how to improve this? Thanks

  • Erlang: How do you reload an application env configuration?

    - by mwt
    How do you reload an application's configuration? Or, what are good strategies for managing dynamic application configuration? For example, let's say I had log levels and I wanted to change them at runtime. Also, let's assume this is one of many such options. Does it make sense to have a "configuration server" that holds configuration state for other parts of the application to query? Do people do that or did I just make it up?

  • Should I use "User Defined Functions" in SQL server, or C#?

    - by sanity
    I have a fairly complicated mathematical function that I've been advised should be implemented as a User Defined Function in SQL Server so that it can be used efficiently from within a SQL query. The problem is that it must be very efficient as it may be executed thousands of times per second, and I subsequently heard that UDFs are very inefficient. Someone suggested that I could implement the function in C# instead, and that this would be much more efficient. What should I do?

  • Create unique links for indvidual elements of a PHP generated table

    - by typoknig
    I have a table generated from some PHP code that lists a SMALL amount of important information for employees. I want to make it so each row, or at least one element in each row can be clicked on so the user will be redirected to ALL of the information (pulled from MySQL database) related to the employee who was clicked on. I am not sure how would be the best way to go about this, but I am open to suggestions. I would like to stick to PHP and/or JavaScript. Below is the code for my table: <table> <tr> <td id="content_heading" width="25px">ID</td> <td id="content_heading" width="150px">Last Name</td> <td id="content_heading" width="150px">First Name</td> <td id="content_heading" width="75px">SSN</td> </tr> <?php $user = 'user'; $pass = 'pass'; $server = 'localhost'; $link = mysql_connect($server, $user, $pass); if (!$link){ die('Could not connect to database!' . mysql_error()); } mysql_select_db('mydb', $link); $query = "SELECT * FROM employees"; $result = mysql_query($query); mysql_close($link); $num = mysql_num_rows($result); for ($i = 0; $i < $num; $i++){ $row = mysql_fetch_array($result); $class = (($i % 2) == 0) ? "table_odd_row" : "table_even_row"; echo "<tr class=".$class.">"; echo "<td>".$row[id]."</td>"; echo "<td>".$row[l_name]."</td>"; echo "<td>".$row[f_name]."</td>"; echo "<td>".$row[ssn]."</td>"; echo "</tr>"; } ?> </table>
