我想要從唯一1表中以unique1表中存在的相同順序插入數據到唯一2表中。 insert /*+ append */ into unique2
select * from unique1 A where not exists (select 1 from match1 B where A. promolog_key = B. promolog_key) order by rowid a
先生，我怎樣才能返回我的數據庫的rowid取決於輸入名稱，數字？此代碼每次只返回值0。我的主鍵是KEY_ROWID。感謝您的幫助提前 //get rowid
public long getRowId(String name, String number)
{
// TODO Auto-generated method stub
String[] columns = new
create or replace
PROCEDURE PROMOLOG1 AS
CURSOR rule IS SELECT * FROM business_rules; --this table had where conditions to use
TYPE r_cursor IS REF CURSOR;
ruleMatch r_cursor;
row_id VARCHAR2(20)
刪除重複行後的邏輯是什麼？ 我知道這是用於刪除重複行的查詢。 delete from tvsemp e where rowid>(select min(rowid) from tvsemp m where e.ename=m.ename);
這裏的時候，我分子查詢即第一select min(m.rowid) from tvsemp e, tvsemp m where e.ename=m.ena
