使用Oracle SQL Developer
我创建了一个简单的程序。该过程编译成功,但是当我键入命令时:
execute CMPPROJECTPROCSELECT();
BEGIN CMPPROJECTPROCSELECT(); END;
我收到以下错误:
Error starting at line : 1 in command -
execute CMPPROJECTPROCSELECT()
Error report -
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'CMPPROJECTPROCSELECT'
ORA-06550: line 1, column 7:
PL/SQL: Statement ignored
06550. 00000 - "line %s, column %s:\n%s"
*Cause: Usually a PL/SQL compilation error.
*Action:
Error starting at line : 2 in command -
BEGIN CMPPROJECTPROCSELECT(); END;
Error report -
ORA-06550: line 1, column 7:
PLS-00306: wrong number or types of arguments in call to 'CMPPROJECTPROCSELECT'

请帮我解决这个问题。我知道这是一个小错误。我还正确指定了数据类型和名称声明。
我的程序代码是
CREATE OR REPLACE PROCEDURE CMPPROJECTPROCSELECT(
p_projectname IN VARCHAR2,
p_description OUT VARCHAR2)
IS
BEGIN
SELECT DESCRIPTION
INTO p_description
FROM CMPPROJECT
WHERE PROJECTNAME = p_projectname;
EXCEPTION
WHEN NO_DATA_FOUND THEN
p_description:= NULL;
COMMIT;
END CMPPROJECTPROCSELECT;
