Plsql Oracle:将序列设置为特定值

我正在使用liquibase来管理我的模式。我有一大堆insert语句。我已经硬编码了主要身份证号码。完成所有插入后，我希望将序列值更改为比表中主键的最大值多1。为此，我编写了一个PL/SQL，如下所示。但是，当我执行

时，从dual中选择ArtifactTypes_id_seq.nextval它仍然递增0

SET SERVEROUTPUT ON SIZE 1000000
DECLARE
    sequence_id NUMBER;
BEGIN

    SELECT NVL(MAX(idArtifactType), 0) + 1 INTO sequence_id FROM ArtifactTypes;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE saas.ArtifactTypes_id_seq INCREMENT BY ' || sequence_id;
    EXECUTE IMMEDIATE 'SELECT ArtifactTypes_id_seq.nextval FROM dual';
    EXECUTE IMMEDIATE 'ALTER SEQUENCE saas.ArtifactTypes_id_seq INCREMENT BY 1';
    DBMS_OUTPUT.put_line('Executed "ALTER SEQUENCE saas.ArtifactTypes_id_seq INCREMENT BY ' || sequence_id || '"');
END;
/

DBMS_输出提供以下输出-

执行“将序列saas.ArtifactTypes\u id\u seq增量71”

我遗漏了什么？我做错了吗？
注意：我尝试从SQLDeveloper执行这些SQL。
您需要删除序列，然后重新创建它，使用start WITH子句分配初始值，例如：

CREATE SEQUENCE saas.ArtifactTypes_id_seq
  START WITH 72;

另外，从序列中选择NEXTVAL会自动增加1。
因此我发现了问题。下面应该是PL/SQL-

SET SERVEROUTPUT ON SIZE 1000000
DECLARE
    sequence_id NUMBER;
    temp_seq NUMBER;
BEGIN
    SELECT NVL(MAX(idArtifactType), 0) + 1 INTO sequence_id FROM ArtifactTypes;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE saas.ArtifactTypes_id_seq INCREMENT BY ' || sequence_id;
    SELECT ArtifactTypes_id_seq.nextval into temp_seq FROM dual;
    EXECUTE IMMEDIATE 'ALTER SEQUENCE saas.ArtifactTypes_id_seq INCREMENT BY 1';
    DBMS_OUTPUT.put_line('Executed "ALTER SEQUENCE saas.ArtifactTypes_id_seq INCREMENT BY ' || sequence_id || '"');
END;
/

以下语句-

立即执行'SELECT ArtifactTypes_id_seq.nextval FROM dual'

已更改为

选择ArtifactTypes_id_seq.nextval从dual进入temp_seq

成功了
