Insert new column after get then XML

Question

Hello,
I use Oracle 8i and SQL Utility. I want to do a query and after that, modify or insert the values of some elements.
xmlgen.clearBindValues;
xmlgen.setBindValue('vCity', vCity);
xmlSQL := 'select name, depto from emp where city = :vCity';
xmlString := xmlgen.getXML(xmlSQL);
Now, I want to read each line and modify
the name or depto values before create the
XML file. How can I do this?
Thanks,
Arthur Rafael

Again, it depends.
If you just want to fix your query
Create Table TABLE AS
Select column1, to_char(column2) column2, column3 from Table1
UNION
Select column1, column2, column3 from Table2;If you want to fix Table1
ALTER TABLE table1
  ADD( column2_varchar2 VARCHAR2(30) );
UPDATE table1
   SET column2_varchar2 = to_char( column2 );
ALTER TABLE table1
  DROP( column2 );
ALTER TABLE table1
  RENAME COLUMN column2_varchar2 TO column2Taking a step back, though, why are you creating a new table that is the result of unioning two other tables? Is this a one-time data model change? Or is this part of some ongoing process?
