oracle sequence语句重置方介绍

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
复制代码 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
复制代码 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;
