PLS-00221: 'GET_SAL' is not a procedure or is undefined
ORA-06550: line 1, column 7:

PL/SQL: Statement ignored

出现类&＃20284;这样的错误，是因为没有将返回&＃20540;赋给一个&＃20540; ，因此

f you want to execute a function you have to collect the return value into a variable.

So you need to define a variable and execute function to return into the variable as below

and run it using the run Script option not the Run Statement option.

variable ret varchar2(20);execute:ret:=check_login(dd,dd);select:ret from dual

Or if you do it from plsql

declare  v_ret varchar2(100);begin

  v_ret:=check_login(a,b);end;
