Populating multiple text fields from a database table...

Question

I have a database table with several fields e.g. drawing_no, title, date_entered etc..I have a form that has the same fields. I want to be able to input a value into drawing_no field, and have it retrieve all the other values from the database - if they exist, or return blanks/nulls if it does not exit. I know how to do this for a single field, but not for retrieving multiple fields

Hi ,
You can create a before header page process and fetch all the fields from database, or you can take a look at in-built process Automated Row Fetch.
For e.g. lets say u have field1, field2, field3, field4 and field5 based on col1, col2, col3, col4, col5 from table tab1
Now create a page process of type PL-SQL and give a meaningful name to the process and accept the default as on Load Before header. In the "Enter PL/SQL Page Process" block enter a code similar to this one
DECLARE
BEGIN
IF :drawing_no IS NOT NULL THEN
  SELECT col1, col2, col3, col4, col5 INTO :field1, :field2, :field3, :field4, :field5
  FROM tab1 WHERE drawing_no = :drawing_no ;
END IF;
EXCEPTION WHEN NO_DATA_FOUND THEN
           NULL;
END;The above block will fetch the records into input fields every time u refresh the page.
Hope this helps.
