如何从表中选择，其中文本框=带聚合的公式（Xojo+SQLite）

我有一个列表

全名， 集团号， Tdate， 日程 克拉蒙特， 德拉蒙特， 我数。 我想选择textbox111.text大于公式SUMCramount*26/SUMDramount+Iamount的列

下面的SQL给我语法错误，请有人帮我数据库是SQLITE和XOJO编程

 sql= "SELECT Fullname, GroupNo, Tdate, Schedule,( SUM(Cramount)*26)/SUM(Dramount+Iamount) AS ok FROM Trans WHERE Branchcode = '1210 - Loans'GROUP BY LoanID  HAVING SUM(Cramount)*26/(SUM(Dramount+Iamount)) < '"TextBox111.text'""

您的SQL字符串有两个错误，TextBox111.text后面的单引号和双引号的方式错误，您需要将该控制值与+连接起来，因为Xojo不进行字符串插值

尝试以下方法：

sql= "SELECT Fullname, GroupNo, Tdate, Schedule, (SUM(Cramount)*26)/SUM(Dramount+Iamount) AS ok FROM Trans WHERE Branchcode = '1210 - Loans' GROUP BY LoanID HAVING SUM(Cramount)*26/(SUM(Dramount+Iamount)) < '" + TextBox111.text + "'"

我很确定SQLite支持在having子句中使用agregate字段的别名

sql= "SELECT Fullname, GroupNo, Tdate, Schedule, (SUM(Cramount)*26)/SUM(Dramount+Iamount) AS ok FROM Trans WHERE Branchcode = '1210 - Loans' GROUP BY LoanID HAVING ok < '" + TextBox111.text + "'"

SQL还引用了表中未提及的两个字段Branchcode和LoanID，希望您只是忘记了提及它们。
