Unable to call a procedure from another procedure

Question

Hi there,
I have created two procedures under my user login. Both of them have the same parameters.
I was trying to call the other procedure from one procedure and am getting error message.
Both the procedures are saved in different files. I am using LINUX command editor.
Precedure1:
CREATE PROCEDURE remove_emp (emp_no number) as
BEGIN
delete from sailors s where s.s_no = remove_emp.emp_no;
END;
Procedure2:
CREATE PROCEDURE u_table (del_emp number) as
BEGIN
exec remove_emp(del_emp);
END;
/While am calling, this is what I am getting
SQL> exec u_table(1003);
BEGIN u_table(1003); END;
ERROR at line 1:
ORA-06550: line 1, column 7:
PLS-00905: object RAJIV.U_TABLE is invalid
ORA-06550: line 1, column 7:
PL/SQL: Statement ignoredPlease help me with this.
Thanks
Rajiv

First thing..
PLS-00905: object RAJIV.U_TABLE is invalidMeans..the procedure is not valid...meaning not compiled properly...because...u were using "exec remove_emp(del_emp);".... reason being is exec is valid in Sql*Plus... and u cant use it in a procedure ..with the same syntax ( dont ask me why..) unless u use dynamic sql.. u can directly call the procedure like...
CREATE PROCEDURE u_table (del_emp number) as
BEGIN
remove_emp(del_emp);
END;
delete from sailors s where s.s_no = remove_emp.emp_no;Secondly ... (Just a suggestion).... aliases are better used when u have multiple tables and complex queries..or may be sometimes the table name is too long and confusing... avoid them when not neccessary
