Oracle SP给出PLS-00201 ORA-06550错误

Question

I have created a SP as below: The purpose is the pass 2 params to xyz. The SP xyz will read records from a table t1 and store in a cursor. xyz in turn will call another SP sp2 in a loop with the records stored in the cursor. When I tried to run this in TOAD, I got the error

ORA-06550: line 2, column 3:
PLS-00201: identifier 'abc.xyz' must be declared
ORA-06550: line 2, column 3:
PL/SQL: Statement ignored

create or replace PROCEDURE abc.xyz(year IN number, ver IN number)
IS 
  cursor my_cur  (year IN number, ver IN number) IS
    select p1, p2, p3, 
           p4, p5, p6 
      from abc.t1 
     where p2=year  
       and p3=ver;   

  my_row  my_cur%rowtype;
  params varchar2(1000);
BEGIN
    for IN my_cur(year, ver) loop
        params := '' || my_row.p1      || ''  ||',' 
                     || my_row.p2 || ',' 
                     || my_row.p3     || ',' 
                     || my_row.p4 || ',' 
                     || my_row.p5 || ',' 
                     || '' || my_row.p6 || ''

         dbms_output.put_line(params); 

         exec sp2(params);
         params := '';
    end loop;
END;

Answer 1

The error is basically telling you there is no VALID (compiled) procedure by that name or you called with incorrect type/number of parameters!

Did your code compile? It had 2 errors and i post here with the corrections.

CREATE OR REPLACE PROCEDURE abc.xyz (year IN NUMBER, ver IN NUMBER)
IS
   CURSOR my_cur (year IN NUMBER, ver IN NUMBER)
   IS
      SELECT p1,
             p2,
             p3,
             p4,
             p5,
             p6
        FROM abc.t1
       WHERE p2 = year AND p3 = ver;

   my_row   my_cur%ROWTYPE;
   params   VARCHAR2 (1000);
BEGIN
   FOR my_row IN my_cur (year, ver)
   LOOP
      params :=
            ''
         || my_row.p1
         || ''
         || ','
         || my_row.p2
         || ','
         || my_row.p3
         || ','
         || my_row.p4
         || ','
         || my_row.p5
         || ','
         || ''
         || my_row.p6
         || '';

      DBMS_OUTPUT.put_line (params);

       sp2(params);
      params := '';
   END LOOP;
END;

Answer 2

This one is compiling

exec within a PLSQL block is not valid syntax. exec is a shortcut for sqlplus begin p; end;

 1  create or replace PROCEDURE xyz(year IN number, ver IN number)
  2  IS
  3    cursor my_cur  (year IN number, ver IN number) IS
  4  select p1, p2, p3,
  5     p4, p5, p6
  6    from t1
  7   where p2=year
  8     and p3=ver;
  9    --my_row  my_cur%rowtype;
 10    params varchar2(1000);
 11  BEGIN
 12  for  my_row IN my_cur(year, ver) loop
 13      params := '' || my_row.p1      || ''  ||','
 14           || my_row.p2 || ','
 15           || my_row.p3     || ','
 16           || my_row.p4 || ','
 17           || my_row.p5 || ','
 18           || '' || my_row.p6 || '';
 19       dbms_output.put_line(params);
 20       sp2(params);
 21       params := '';
 22  end loop;
 23* END;

Procedure created.
