Body
I have the following sql query: select supplier, name, date, turnover from turnover order by supplier <pre><code> supplier name date turnover -------- --------- ---------- ---------- 001 supplier1 01.01.2012 129,67 001 supplier1 02.05.2012 12.145,89 001 supplier1 03.07.2012 6.830,90 002 supplier2 01.01.2012 -11,55 002 supplier2 03.09.2012 4.500,61 </code></pre> Is it possible to replace the repeating values with a NULL, so the resulting table looks like this (see below)? <pre><code> supplier name date turnover -------- --------- ---------- ---------- 001 supplier1 01.01.2012 129,67 02.05.2012 12.145,89 03.07.2012 6.830,90 002 supplier2 01.01.2012 -11,55 03.09.2012 4.500,61 </code></pre> Any advice would be appreciated!

Guidance

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.
