上面的语句在oracle中能正常执行，如何将它改成DB2能支持的语句
------解决方案--------------------------------------------------------
update xprice_fpfeedparam a
set bidformula = '0-|1_' || (select engname from param_ccypair where a.ratecode = CCYPAIRID and a.termid = 1 and engname like '%USD%') || '_O/N' || '_ASK|-|1_' || select engname from param_ccypair where a.ratecode = CCYPAIRID and a.termid = 1 and engname like '%USD%') || '_T/_ASK|' ,
askformula = '0-|1_' || select engname from param_ccypair where a.ratecode = CCYPAIRID and a.termid = 1 and engname like '%USD%') || '_O/N' || '_BID|-|1_' || select engname from param_ccypair where a.ratecode = CCYPAIRID and a.termid = 1 and engname like '%USD%') || '_T/N_BID|';
