oracle中的procedure编写和使用详解

CREATE [OR REPLACE] PROCEDURE procedure_name
[(parameter_list)]
{IS|AS}
[local_declarations]
BEGIN
executable_statements
[EXCEPTION exception_handlers]
END [procedure_name];

 parameter_name1 [in | out | in out] type, parameter_name1 [in | out] type [,........]

outcur OUT BASIC_CURSOR:
 OPEN outcur FOR SELECT col1,col2 FROM tablename

create or replace procedure putNum(P_Date in date, P_year out varchar2) is 
 v_num number(8) := 1;

[EXECUTE]|[CALL] procedure_name[(parameter,…n)]
