oracle sequence语句重置方介绍

前端技术 2023/09/04 Oracle
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;
