我将一些代码从 sql 重写为 sql_oracle，但我找不到 <>'' 的解决方案。
!= '' 将不起作用。
如果我可以翻译 <>'' 它应该可以工作。我已经用谷歌搜索了很多，但找不到任何 awnsers .. 我在编码方面没有那么丰富的经验，所以也许这里有人可以帮助我。
这是sql代码
SQL_genericp2.Insert(
"from tsdsmd trip "
" left outer join "
" ( "
" select tsroma.* from tsroma "
" where tsroma.tstohn <> '' "
" ) leg "
" on trip.dosvlg = leg.tsrido "
" left outer join dosier shipment "
" on leg.dosvlg = shipment.dosvlg "
" left outer join "
" ( "
" select * from tsdsco "
" where laloin = 1 and volgnr = 1 "
" ) tsdsco1 "
" on leg.dosvlg = tsdsco1.dosvlg "
" left outer join "
" ( "
" select * from tsdsco "
" where laloin = 2 and volgnr = 1 "
" ) tsdsco2 "
" on leg.dosvlg = tsdsco2.dosvlg "
,1);

这是 sql_orcale 代码：
