SqlServer中是这样：

if NOT exists(SELECT * FROM Setting WHERE ID=0)INSERT INTO Setting(ID,Title,SearchKeys, ServiceIntervalSecond,SleepMillisecondPerSearch) VALUES(0,@title,@searchKeys,@serviceIntervalSecond,@sleepMillisecondPerSearch) ELSE UPDATE Setting SET Title=@title,SearchKeys=@searchKeys,ServiceIntervalSecond=@serviceIntervalSecond, SleepMillisecondPerSearch=@sleepMillisecondPerSearch

 

MySqL中是这样：

INSERT INTO `his_examine_result` (Mid,His_Examine_Mid, His_File_Mid, ResultType, His_Employee_Mid,                                  His_Employee_Name, ExamineResult, ExamineItemName, ExamineStandardName,                                   ExamineItemUnit, ExamineHighValue, ExamineLowValue, ExamineDiscription, Discription)    VALUES ($mid,$examineMid,$fileMid,1,null,null,'',$itemName,$standName,$itemUnit,$highValue,$lowValue,'','') ON DUPLICATE KEY UPDATE ExamineResult=$result,ExamineDiscription=$dis
