Hey guys,

I'm having a problem regarding on how am I going to delete records in a same table if that record already exist. Here's the situation

for example I have a Table called myTable

and this table have a record of.. lets say

dog
cat
chicken
goat
cow
dog
cat

how can I delete the duplicate record if those records belongs in a same table.

Another problem is what is the syntax in subtracting two time entries.

ex. I want to get the minutes difference of 18:30 to 08:00.

Thanks a lot.
