由 不想你离开。 提交于 2019-12-05 05:11:20
I have created this activity that should allow me to open a new activity once a button has been pressed. However the OnClickListener does not seem to be working. Am I declaring the buttons wrong?

由 只愿长相守 提交于 2019-12-05 03:00:16
问题 I need to add a case statement in a where clause. I want it to run either statement below depending on the value of TermDate. Select * from myTable where id = 12345 AND TermDate CASE WHEN NULL THEN AND getdate() BETWEEN StartDate AND DATEADD(dd, 30, StartDate) ELSE AND GETDATE < TermDate END 回答1: Why not just use an OR condition? SELECT * FROM myTable WHEN id = 12345 AND ((TermDate IS NULL AND getdate() BETWEEN StartDate AND DATEADD(dd, 30, StartDate)) OR GETDATE() < TermDate) 回答2: Since we

Changing case (upper/lower) on adding data through Django admin site

由 Deadly 提交于 2019-12-05 01:11:56
问题 I'm configuring the admin site of my new project, and I have a little doubt on how should I do for, on hitting 'Save' when adding data through the admin site, everything is converted to upper case... Edit: Ok I know the .upper property, and I I did a view, I would know how to do it, but I'm wondering if there is any property available for the field configuration on the admin site :P 回答1: If your goal is to only have things converted to upper case when saving in the admin section, you'll want

Nested CASE statements in MySQL

由 放肆的年华 提交于 2019-12-04 22:47:40
My first time working with CASE Logic in SQL statements. Everything works if I remove the CASE statements, so the SQL is valid without it. I need to calculate the total item price based on a couple of things. If "Sales Price" is active AND "Option Upcharge" has a value, the total is: Qty * (Sales Price + Option Upcharge) If "Sales Price is inactive AND "Option Upcharge" has a value, the total is: Qty * (Price + Option Upcharge) If "Sales Price" is active AND "Option Upcharge" has NO value, the total is: Qty * Sales Price If "Sales Price is inactive AND "Option Upcharge" has NO value, the total

问题 I'm coding in SML for an assignment and I've done a few practice problems and I feel like I'm missing something- I feel like I'm using too many case statements. Here's what I'm doing and the problem statements for what I'm having trouble with.: Write a function all_except_option, which takes a string and a string list. Return NONE if the string is not in the list, else return SOME lst where lst is like the argument list except the string is not in it. fun all_except_option(str : string, lst :

Title Case in JavaScript for diacritics (non-ASCII)

由 前提是你 提交于 2019-12-04 19:19:02
Is it possible to create a JavaScript function that can convert a string to title case but one that works with non-ASCII (Unicode) characters? For example with characters like: Áá Àà Ăă Ắắ Ằằ Ẵẵ Ẳẳ Ââ Ấấ Ầầ Ẫẫ Ẩẩ Ǎǎ Åå Ǻǻ Ää Ǟǟ Ãã Éé Èè Ĕĕ Êê Ếế Ềề Ễễ Ểể Ěě Ëë Ẽẽ Ėė Ȩȩ Ḝḝ Ęę Ēē Ḗḗ Ḕḕ etc. For example if the string is "anders ångström", it should transform it into "Anders Ångström". The script that already exists it will transform into "Anders åNgström". Try this: var str = 'anders ångström'; str = str.replace(/[^\s]+/g, function(word) { return word.replace(/^./, function(first) { return first

Why “final static int” can be used as a switch's case constant but not “final static <your enum>”

由 China☆狼群 提交于 2019-12-04 15:54:21
问题 Why is this int switch valid: public class Foo { private final static int ONE = 1; private final static int TWO = 2; public static void main(String[] args) { int value = 1; switch (value) { case ONE: break; case TWO: break; } } } While this enum switch is not: import java.lang.annotation.RetentionPolicy; public class Foo { private final static RetentionPolicy RT = RetentionPolicy.RUNTIME; private final static RetentionPolicy SRC = RetentionPolicy.SOURCE; public static void main(String[] args)

SQL Conditional JOIN column [duplicate]

由 寵の児 提交于 2019-12-04 14:41:59
This question already has answers here : SQL Conditional AND (4 answers) Closed 5 years ago . I want to determine the JOIN column based on the value of the current row. So for example, my job table has 4 date columns: offer_date, accepted_date, start_date, reported_date. I want to check against an exchange rate based on the date. I know the reported_date is never null, but it's my last resort, so I have a priority order for which to join against the exchange_rate table. I'm not quite sure how to do this with a CASE statement, if that's even the right approach. INNER JOIN exchange_rate c1 ON c1
