前端之家收集整理的这篇文章主要介绍了oracle sequence语句重置方介绍，前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。

在开发过程中，可能会用到oracle sequence语句,本文以oracle sequence语句如何重置进行介绍，需要的朋友可以参考下
Oracle重置sequence语句1
sql 代码
<div class="codetitle"><a style="CURSOR: pointer" data="93665" class="copybut" id="copybut93665" onclick="doCopy('code93665')"> 代码如下:

<div class="codebody" id="code93665">
DECLARE
n NUMBER(10 );
tsql VARCHAR2(100 );
p_seqName varchar2(20 );
BEGIN
p_seqName := 'SEQ_RUN_ID';
EXECUTE IMMEDIATE 'SELECT ' || p_seqName || '.NEXTVAL FROM dual ' INTO n;
n := - (n - 1);
tsql := 'alter sequence '|| p_seqName ||' increment by ' || n;
EXECUTE IMMEDIATE tsql;
EXECUTE IMMEDIATE 'SELECT ' || p_seqName || '.NEXTVAL FROM dual ' INTO n;
tsql := 'alter sequence '|| p_seqName ||' increment by 1' ;
EXECUTE IMMEDIATE tsql;
EXCEPTION
WHEN OTHERS THEN
dbms_output.put_line( sqlERRM);
END;

Oracle重置sequence语句2
sql 代码
<div class="codetitle"><a style="CURSOR: pointer" data="85379" class="copybut" id="copybut85379" onclick="doCopy('code85379')"> 代码如下:

<div class="codebody" id="code85379">
CREATE OR REPLACE PROCEDURE RESET_SEQUENCE(p_sSeqName IN VARCHAR2)
IS
n NUMBER(10 );
tsql VARCHAR2(100 );
BEGIN
EXECUTE IMMEDIATE 'SELECT ' || p_sSeqName || '.NEXTVAL FROM dual '
INTO n;
n := - (n - 1);
tsql := 'alter sequence ' || p_sSeqName || ' increment by ' || n;
EXECUTE IMMEDIATE tsql;
EXECUTE IMMEDIATE 'SELECT ' || p_sSeqName || '.NEXTVAL FROM dual '
INTO n;
tsql := 'alter sequence ' || p_sSeqName || ' increment by 1' ;
EXECUTE IMMEDIATE tsql;
EXCEPTION WHEN OTHERS THEN
NULL;
END RESET_SEQUENCE;
