How do I fill in the gaps with data?

Question

Hi,
I have paragraphs of data with a header which holds the ID I need to have against each row of that data.
I want the Patient ID to fill fields below that row (where the 'Obs' and sequential numbers are) until it gets to the next patient id, and then make it do the same again and again until the end.
Can this be done in a single SQL UPDATE statement?
Thanks Daniel
This is the data, this is all one column:
Patient ID=1000207 regimen=EFV+ZDV+ddI Randomization Date=26/03/2004

Hi,
welcome to the forum.
Please read SQL and PL/SQL FAQ
Kindly post sample data (CREATE TABLE and INSERT statements), explain the business requirement and post your expected output.
Don't forget to mention also your Oracle version as result of
SELECT * FROM v$version;When you put some code or output please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
Regards.
