oracle utl_lms用变量替换整数

UTL_LMS.FORMAT_MESSAGE调用VARCHAR参数,但doc(11gR2)示例中的类型转换似乎与整数变量兼容.但是,我的％d永远不会被替换.

我希望得到一些想法/建议.下面是失败的一个例子.

运行以下内容：

DECLARE
  C_INTRANSITIVE_VERB CONSTANT VARCHAR2(50) := 'breakdance';
  C_SUBJECT_NOUN CONSTANT VARCHAR2(50) := 'hobbit';
  C_PREPOSITION_OBJECT CONSTANT VARCHAR2(50) := 'wookie';
  C_MULTIPLIER CONSTANT INTEGER := 19;
  C_TEMPLATE CONSTANT VARCHAR2(400) := 'The %s likes to %s with the %s %d times a day.';
BEGIN
  DBMS_OUTPUT.PUT_LINE('My integer is: '|| C_MULTIPLIER);
  DBMS_OUTPUT.PUT_LINE(
      UTL_LMS.FORMAT_MESSAGE(C_TEMPLATE,C_SUBJECT_NOUN,C_INTRANSITIVE_VERB,C_PREPOSITION_OBJECT,C_MULTIPLIER)
  );
END;
/

产量：

My integer is: 19

The hobbit likes to breakdance with the wookie times a day.

但是,下面转换raw int fine：

DECLARE
  C_INTRANSITIVE_VERB CONSTANT VARCHAR2(50) := 'breakdance';
  C_SUBJECT_NOUN CONSTANT VARCHAR2(50) := 'hobbit';
  C_PREPOSITION_OBJECT CONSTANT VARCHAR2(50) := 'wookie';
  C_MULTIPLIER CONSTANT INTEGER := 19;
  C_TEMPLATE CONSTANT VARCHAR2(400) := 'The %s likes to %s with the %s %d times a day.';
BEGIN
  DBMS_OUTPUT.PUT_LINE('My integer is: '|| C_MULTIPLIER);
  DBMS_OUTPUT.PUT_LINE(
      UTL_LMS.FORMAT_MESSAGE(C_TEMPLATE,19)
  );
END;
/

My integer is: 19

The hobbit likes to breakdance with the wookie 19 times a day.

以下解决方法是不合需要的.

DECLARE
  C_INTRANSITIVE_VERB CONSTANT VARCHAR2(50) := 'breakdance';
  C_SUBJECT_NOUN CONSTANT VARCHAR2(50) := 'hobbit';
  C_PREPOSITION_OBJECT CONSTANT VARCHAR2(50) := 'wookie';
  C_MULTIPLIER CONSTANT INTEGER := 19;
  C_TEMPLATE CONSTANT VARCHAR2(400) := 'The %s likes to %s with the %s %d times a day.';
BEGIN
  DBMS_OUTPUT.PUT_LINE('My integer is: '|| C_MULTIPLIER);
  DBMS_OUTPUT.PUT_LINE(
      UTL_LMS.FORMAT_MESSAGE(C_TEMPLATE,TO_CHAR(C_MULTIPLIER))
  );
END;
/

My integer is: 19

The hobbit likes to breakdance with the wookie 19 times a day.

>为什么FORMAT_MESSAGE接受原始整数,但在INTEGER类型(或一般NUMBER类型)变量上失败？
>是否有更好的预包装(11g)dbms消息格式化器已经可用？
> oracle 11g中有关清除消息格式的任何其他建议吗？我会考虑包装java的MessageFormat / String #format(),或者创建一个处理char类型转换的FORMAT_MESSAGE委托,但更愿意为所有需要它的数据库避免这种情况,而且我不太热衷于“只记得“to_char()到处都是因为失败相当安静.

谢谢！

该示例指定PLS_INTEGER而不是Integer或Number.我已经测试了这个,并且使用PLS_INTEGER可以在Integer没有的情况下工作.

我知道这不是一个理想的解决方案,我不确定是否定义您的变量,因为pls_integer将是一个选项.但可能会有一些帮助.

DECLARE
  C_INTRANSITIVE_VERB CONSTANT VARCHAR2(50) := 'breakdance';
  C_SUBJECT_NOUN CONSTANT VARCHAR2(50) := 'hobbit';
  C_PREPOSITION_OBJECT CONSTANT VARCHAR2(50) := 'wookie';
  C_MULTIPLIER CONSTANT PLS_INTEGER := 19;
  C_TEMPLATE CONSTANT VARCHAR2(400) := 'The %s likes to %s with the %s %d times a day.';
BEGIN
  DBMS_OUTPUT.PUT_LINE('My integer is: '|| C_MULTIPLIER);
  DBMS_OUTPUT.PUT_LINE(
      UTL_LMS.FORMAT_MESSAGE(C_TEMPLATE,C_MULTIPLIER)
  );
END;

给出输出

My integer is: 19
The hobbit likes to breakdance with the wookie 19 times a day.
