oracle庫更新數據和類型轉換

更新oracle

sql6 = "UPDATE 表名 set (value)=(:value) where coeffs_id=(:coeffs_id)"
cur_36.prepare(sql6)
cur_36.execute(None, {'value': value, 'coeffs_id': coeffs_id})
 conn_36.commit()`

sql語句中常見類型轉換

    sql2 = "select  cast(community_id as varchar) community_id,sale_count,ppe from 表名 where is_defalt=true "
   

整數轉換成字符串 ：cast(community_id as varchar) 別名
字符串轉換成整數 ：cast(community_id as int) 別名

TO_TIMESTAMP_TZ(‘2018-11-11 10:47:16’,‘YYYY-MM-DD HH24:MI:SS’)
to_char(屬性名，格式) 常用於時間轉字符串
to_date(屬性名，格式) 常用於字符串轉日期
