Oracle判斷值為非數字,Oracle判斷值數字

select * from product_info t where t.contract_detailid is not nulland length(translate(t.contract_detailid,'-.0123456789'||t.contract_detailid,'-.0123456789'))<>length(t.contract_detailid) for update


oracle資料庫中判斷非數字並刪除

建立測試表
create table test(col varchar2(100)); insert into test values ('123-1324');insert into test values ('34141回');insert into test values ('821648462()');
運行語句
select translate(col, '0' || translate(col, '#0123456789', '#'), '0') from test
結果
