Question

我正在尝试在主存储过程中执行^存储过程。但它不起作用。

错误（11,9）：PLS-00103：遇到以下其中一项时遇到符号“FN_UPD”:: =。（@％;符号“：=”代替“FN_UPD”继续。

代码：

create or replace
procedure FN_READ

is
   cursor C_1 is select distinct(COLUMN1) from TB_SOURCE;
   cursor C_2 is select distinct(COLUMN2) from TB_SOURCE;
   cursor C_3 is select distinct(COLUMN3) from TB_SOURCE;
BEGIN

    for f in C_1
    LOOP
   EXEC FN_UPD('A', 'A');

    end LOOP;


    for f in C_2
    LOOP
   EXEC PROCEDURE FN_UPD(f.COLUMN2, 'M')
    end LOOP;

    for f in C_3
    LOOP
    EXEC FN_UPD(f.COLUMN3, 'O')

    end LOOP;

EXCEPTION
WHEN OTHERS THEN
   raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR-    '||SQLERRM);
END;

Answer 1

EXEC（同样适用于EXEC PROCEDURE）在PL / SQL中不起作用，直接使用过程名称：

BEGIN
    FN_UPD('A', 'A');
END;
/

Answer 2

替换

 EXEC FN_UPD(f.COLUMN3, 'O')

和

 EXEC PROCEDURE FN_UPD(f.COLUMN2, 'M')

与

FN_UPD(f.COLUMN3, 'O');

和

FN_UPD(f.COLUMN2, 'M');

分别

请注意尾随;。

所以，你的程序变成了

create or replace
procedure FN_READ

is
   cursor C_1 is select distinct(COLUMN1) from TB_SOURCE;
   cursor C_2 is select distinct(COLUMN2) from TB_SOURCE;
   cursor C_3 is select distinct(COLUMN3) from TB_SOURCE;
BEGIN

    for f in C_1 LOOP
        FN_UPD('A', 'A');
    end LOOP;


    for f in C_2 LOOP
        FN_UPD(f.COLUMN2, 'M')
    end LOOP;

    for f in C_3 LOOP
         FN_UPD(f.COLUMN3, 'O')
    end LOOP;

EXCEPTION
WHEN OTHERS THEN
   raise_application_error(-20001,'An error was encountered - '||SQLCODE||' -ERROR-    '||SQLERRM);
END;

无法执行存储过程
