[HACKERS] a problem when poring from Oracle's PL/SQL to PLPGSQL

[billy]

pgsql-hackers:

The following is Oracle's PL/SQL

  if resTypeTableName is null
        then                                                            
    queryStr := 'select IntIID, Path FROM aaResourceData' || ' where 
ResType=''' || srcType || ''' and ResID=''' || srcID || '''';                   
                                        
        else                                                                    
                                                      queryStr := 'select 
IntIID, Path FROM ' || resTypeTableName || ' where ResType=''' || srcType || 
''' and ResID=''' ||            
                srcID || '''';                                   
  end if;                                                        

 open cursorSrc for queryStr;


Here queryStr is a variable which type is TEXT OR VARCHAR or other string types.

But in  PLPGSQL, we can only open a cursor this way:

     open cursorSrc for select * from testtable;

We cannot substitude "select * from testtable" with a variable.

Is there another way to handle it?

Thank you for your help. :-)
