估计就是类型的问题。。。楼主你在写语句的时候转换下试试

SQL codecreatetable #t(Macvarchar(50),CompanyIdvarchar(50),CompanyNamevarchar(50),FtpParametervarchar(50))IFNOTEXISTS(SELECT*FROM #tWHERE MAC='aa:22:cc:22:ee:ff')INSERTINTO #t(Mac,CompanyId,CompanyNam¡­

换成下面这个也是不行，
SQL codeIFNOTEXISTS(SELECT*FROM CompanyWHERE MAC='aa')INSERTINTO Company
(Mac,CompanyId,CompanyName,FtpParameter)Values('aa','aabbcc','abc')

是不是我这个SQLite Developer出问题了，但是简单的select语句却可以执行啊？
