Dear all
I have a table with patient id and several laboratory date per patient (from one to several dozens). I would like to give to each records per patient a observation number in ascending order of the laboratory date. How can I store this in a variable obs.

Need urgent help!!!! Confused I would like to do this with PL/SQL

table looks like this (total of 9000 records):
ID laboratory date obs
112 date1 1
112 date2 2
112 date3 3
115 date1 1
115 date2 2
115 date3 3
115 date4 4
115 date5 5
115 date6 6

I am assuming OBS is field name in the table and it is not a variable and you need to update this field in the table.

If my assumption is correct then I suggest you need to read documentation on row_number() analytical function and merge command to achieve this.

Please read OraFAQ Forum Guide, especially "How to format your post?" section.
Make sure that lines of code do not exceed 80 characters when you format.
Indent the code (See SQL Formatter) and align the columns in result.
Use the "Preview Message" button to verify.
Also always post your Oracle version (4 decimals).

Post a test case: create table and insert statements along with the result you want with these data.

Regards
Michel
