Question

我有一个包含2个Form hi = new Form("Hi World", BoxLayout.y()); // Warning: you need to set the theme property "ComponentGroupBool" to true Button button1 = new Button("Button 1", "ButtonMenuCategories"); CheckBox button11 = CheckBox.createToggle("Button 1.1"); CheckBox button12 = CheckBox.createToggle("Button 1.2"); Button button13 = new Button("Button 1.3", "ButtonMenuCategories"); CheckBox button131 = CheckBox.createToggle("Button 1.3.1"); CheckBox button132 = CheckBox.createToggle("Button 1.3.2"); CheckBox button133 = CheckBox.createToggle("Button 1.3.3"); CheckBox button14 = CheckBox.createToggle("Button 1.4"); Button button2 = new Button("Button 2", "ButtonMenuCategories"); Button button3 = new Button("Button 3", "ButtonMenuCategories"); Button button4 = new Button("Button 4", "ButtonMenuCategories"); Button button5 = new Button("Button 5", "ButtonMenuCategories"); Accordion accordion13 = new Accordion(); accordion13.addContent(button13, FlowLayout.encloseCenter(ComponentGroup.enclose(button131, button132, button133))); Accordion accordion1 = new Accordion(); accordion1.addContent(button1, FlowLayout.encloseCenter(ComponentGroup.enclose(button11, button12, accordion13, button14))); Accordion accordion2 = new Accordion(); accordion2.addContent(button2, new Label("Hello")); Accordion accordion3 = new Accordion(); accordion3.addContent(button3, new Label("Hello")); Accordion accordion4 = new Accordion(); accordion4.addContent(button4, new Label("Hello")); Accordion accordion5 = new Accordion(); accordion5.addContent(button5, new Label("Hello")); Container menu = FlowLayout.encloseCenter(ComponentGroup.enclose(accordion1, accordion2, accordion3, accordion4, accordion5)); hi.add(menu); hi.show();字段的现有报告。 1持有日期，2持有时间。我需要创建一个连接两者的公式，然后使用该公式对报表进行排序。示例：

varchar

我想将两个字段一起添加然后排序。在SQL中，我可以执行以下操作，但在水晶报表中，它无法正确转换并引发错误。

SCHEDULED_DATE             SCHEDULED_TIME
2018-04-26 00:00:00.000    1:00 PM
2018-04-26 00:00:00.000    NULL

以下是我对Crystal Report公式的尝试：

ORDER BY Convert(Datetime, SCHEDULED_DATE + Convert(time,ISNULL(SCHEDULED_TIME, '00:00:00.000')))

非常感谢任何帮助。感谢

首先，日期和时间值不应存储为文本。
更好地使用DBMS的相应数据类型。

然后在公式中看到多个问题：

@echo off for /f "usebackq tokens=*" %%a in (`powershell -command " ' one two ' "`) do echo Result is "%%a"和Result is "one two "不支持毫秒
CDate和CDateTime值无法与Date
Time - 列已包含时间部分，您（尝试）再添加一个
连接日期和时间部分时，请用空格分隔

因此，您必须删除时间部分并连接列，而不将其转换为+或SCHEDULED_DATE：

Date

注意：我完全删除了＆＃34; True＆＃34; -part中的时间Time，因为无论如何都不需要全部为零。

创建一个公式，将1个varchar字段w / date和1个varchar w / time转换为1个datetime字段
