sql 序列从另一个音序器中获取的值开始

Question

我需要删除一个音序器并创建另一个以最后一个音序器为起始值的音序器。硬编码起始值不是一种选择。

DECLARE

    NxtVal INTEGER;

BEGIN
    SELECT  (SEQ1.NEXTVAL)+10
        into NxtVal
        From Dual;


    execute immediate  'Create sequence SEQ2
        minvalue 1
        maxvalue 99999
        start with || NxtVal ||
        increment by 1';
END;
/

Answer 1

似乎有一些 ' 缺失：

DECLARE
    NxtVal INTEGER;

BEGIN
    SELECT  (SEQ1.NEXTVAL)+10
        into NxtVal
        From Dual;


    execute immediate  'Create sequence SEQ2 '
        'minvalue 1 '
        'maxvalue 99999 '
        'start with ' || NxtVal || -- missing ' 
        ' increment by 1';
END;
