An Oracle schema is similar to a SS database. (Oracle came first - SS changed the meaning of database. <g>). A schema is a collection of tables with columns (and other database objects).

I am not aware of anything called a field in Oracle databases. I suspect you mean a column, based on many SS applications with user interfaces that have fields to map back to columns.

My suspicion is you want to select the rows from a table based on one or more columns containing the strings 'doc' or 'phy'. That could be accomplished by

  SELECT {list of columns and other column expressions}     FROM table
   WHERE (column LIKE '%doc%' OR column LIKE '%phy%')      AND {other selection criteria}     

Unfortunately, Oracle does not automagically ignore case, so you will likely need to do things like

   WHERE (UPPER(column) LIKE '%DOC%' OR UPPER...

which can have preformance issue if you have a lot of these or the data set is significant (millions of rows)
