getting top count across multiple fields

although i don't think this is do-able using SQL, i would ask and maybe
an expert can help me out. assum i have the following table:

Date Code Count
2006-06-06 abc 1234
2006-06-06 abc 14
2006-06-06 abc 87
2006-06-06 xyz 1353
2006-06-06 xyz 19
2006-06-06 xyz 86
2006-06-06 xyz 176
2006-06-06 xyz 43
2006-06-06 ppp 67
2006-06-06 ppp 45
2006-06-06 ppp 200

what i want is the top 2 Count from each Code for Date like this:

Date Code Count
2006-06-06 abc 1234
2006-06-06 abc 87
2006-06-06 xyz 1353
2006-06-06 xyz 176
2006-06-06 ppp 200
2006-06-06 ppp 67

obviously the following doesn't work:

select Date,Code,Count from myTable group by Date,Code,Count order by
Count desc limit 2

because the order and the limit will be across the whole table not code
by code so you end up with only 2 rows with count 1353 and 1234.

any idea if this is do-able using SQL only?

I'm submitting data through a form with multiple rows on it, that goes out to a processing page, which then scrolls through the data row by row and sends it into a database table. It is truncating one of the strings, the book tile string, so that if there are three words in it, only the first is getting submitted to the table. I have a feeling that it is because I have numbered the fields that are being submitted to the processing page,...

I have two fields that draw their combobox values from the same table. LogBook04.Insurance is the Primary Insurance and LogBook04.SecIns is the Secondary Insurance. Both draw their values from tblInsurance.Insurance. The Primary Insurance or the Secondary Insurance could be any one of the values on the Insurance table. I'm trying to count the occurances of each type of insurance, regardless of whether it is primary or secondary.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
