This is my original question, please consider the above also:</p> <p>+------------------+----------+---------+ </p> <p>¦ Column1 ¦ Column2 ¦ Active ¦ </p> <p>+------------------+----------+---------+ </p> <p>¦ blue widgets ¦ 14 ¦ y ¦ </p> <p>¦ red ¦ 14 ¦ y ¦ </p> <p>¦ redx ¦ 15 ¦ y ¦ </p> <p>¦ blues ¦ 14 ¦ y ¦ </p> <p>¦ blue ¦ 15 ¦ n ¦ </p> <p>¦ bluesX ¦ 15 ¦ n ¦ </p> <p>¦ widgets ¦ 14 ¦ n ¦ </p> <p>+------------------+----------+---------+ </p> <p>Here is my drama... I need to query this: </p> <p>where (Column2 = 14 AND Column2 = 15) and active = 'y' </p> <p>I a result set that has all records where there is active = 'y' for both Column2=14 and Column2=15 </p> <p>I can't figure this out... </p> <p>I can do it so it returns me 14 and 15 with at least one of them as y, but not both. </p> <p>I tried: </p> <p>select * from table where (Column2 = 14 and Column2 = 15) and active = 'y' </p> <p>Of course, this returns nothing, since both can't be 14 and 15 at the same time. </p> <p>So I tried: </p> <p>select * from table where ((Column2 = 14 or Column2 = 15) and active = 'y') </p> <p>And this returns a result set, but not what I want... </p> <p>I need to only return results in column1 that have: </p> <p>column2 = 14 and active = 'y' column2 = 15 and active = 'y' </p> <p>both conditions must be true. </p> <p>Any help? thanks guys! </p>

    1. COCould you give a little more detail on what the table structure is? Are the various pets stored in a separate table with an associative table, or is there something else?

Querying!

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.
