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
代码如下：

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
代码如下：

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;
