PL/SQL是否具有与Java等效的StringTokenizer? [英] Does PL/SQL have an equivalent StringTokenizer to Java's?

问题描述

我使用java.util.StringTokenizer来简单地解析Java中的定界字符串.我在pl/sql中需要相同类型的机制.我可以编写它，但是如果它已经存在，我宁愿使用它.有人知道pl/sql的实现吗?一些有用的替代方法?

I use java.util.StringTokenizer for simple parsing of delimited strings in java. I have a need for the same type of mechanism in pl/sql. I could write it, but if it already exists, I would prefer to use that. Anyone know of a pl/sql implementation? Some useful alternative?

推荐答案

PL/SQL确实包含一个基本的逗号分隔列表(DBMS_UTILITY.COMMA_TO_TABLE).

PL/SQL does include a basic one for comma separated lists (DBMS_UTILITY.COMMA_TO_TABLE).

示例:

DECLARE
   lv_tab_length   BINARY_INTEGER;
   lt_array   DBMS_UTILITY.lname_array;
BEGIN
   DBMS_UTILITY.COMMA_TO_TABLE( list => 'one,two,three,four'
                              , tablen => lv_tab_length
                              , tab => lt_array
                              );

   DBMS_OUTPUT.PUT_LINE( 'lv_tab_length = ['||lv_tab_length||']' );

   FOR i IN 1..lv_tab_length
   LOOP
      DBMS_OUTPUT.PUT_LINE( '['||lt_array( i )||']' );
   END LOOP;

END;
