SQlite listview 的查询结果
[英]SQlite listview results from query case when
问题描述
尝试在具有双 sqlite 条件的 Android 列表视图中显示 sqlite 信息。查询在 DB 浏览器中进行了测试，它给出了期望的结果，但我无法在 Android 中带来相同的结果。
真实的表是这样的：
查询
SELECT
number as no,
outletname as name,
(CASE WHEN week = "WEEK1" THEN sunday ELSE 0 END) AS WK1S,
(CASE WHEN week = "WEEK1" THEN monday ELSE 0 END) AS WK1M,
(CASE WHEN week = "WEEK1" THEN tuesday ELSE 0 END) AS WK1T,
(CASE WHEN week = "WEEK1" THEN wednesday ELSE 0 END) AS WK1W,
(CASE WHEN week = "WEEK1" THEN thursday ELSE 0 END) AS WK1T,
(CASE WHEN week = "WEEK1" THEN saturday ELSE 0 END) AS WK1SA,
(CASE WHEN week = "WEEK2" THEN sunday ELSE 0 END) AS WK2S,
(CASE WHEN week = "WEEK2" THEN monday ELSE 0 END) AS WK21M,
(CASE WHEN week = "WEEK3" THEN sunday ELSE 0 END) AS WK3S,
(CASE WHEN week = "WEEK3" THEN monday ELSE 0 END) AS WK3M,
(CASE WHEN week = "WEEK3" THEN tuesday ELSE 0 END) AS WK3T,
(CASE WHEN week = "WEEK3" THEN wednesday ELSE 0 END) AS WK3W,
(CASE WHEN week = "WEEK3" THEN thursday ELSE 0 END) AS WK3T,
(CASE WHEN week = "WEEK3" THEN saturday ELSE 0 END) AS WK3SA
FROM labels5
UNION all
SELECT "GRAND TOTAL",
NULL ,
COUNT(CASE WHEN week = "WEEK1" AND sunday LIKE "%sunday%" THEN 1 END) AS WK1S,
COUNT(CASE WHEN week = "WEEK1" AND monday LIKE "%monday%" THEN 1 END) AS WK1M,
COUNT(CASE WHEN week = "WEEK1" AND tuesday LIKE "%tuesday%" THEN 1 END) AS WK1T,
COUNT(CASE WHEN week = "WEEK1" AND wednesday LIKE "%wednesday%" THEN 1 END) AS WK1W,
COUNT(CASE WHEN week = "WEEK1" AND thursday LIKE "%thursday%" THEN 1 END) AS WK1T,
COUNT(CASE WHEN week = "WEEK1" AND saturday LIKE "%saturday%" THEN 1 END) AS WK1SA,
COUNT(CASE WHEN week = "WEEK2" AND sunday LIKE "%sunday%" THEN 1 END) AS WK2S,
COUNT(CASE WHEN week = "WEEK2" AND monday LIKE "%monday%" THEN 1 END) AS WK2M,
COUNT(CASE WHEN week = "WEEK1" AND sunday LIKE "%sunday%" THEN 1 END) AS WK3S,
COUNT(CASE WHEN week = "WEEK3" AND monday LIKE "%monday%" THEN 1 END) AS WK3M,
COUNT(CASE WHEN week = "WEEK3" AND tuesday LIKE "%tuesday%" THEN 1 END) AS WK3T,

COUNT(CASE WHEN week = "WEEK3" AND thursday LIKE "%thursday%" THEN 1 END) AS WK3T,
COUNT(CASE WHEN week = "WEEK3" AND saturday LIKE "%saturday%" THEN 1 END) AS WK3SA

由以下原因引起：android.database.sqlite.SQLiteException：没有这样的功能： GRANDTOTALNULLCOUNT （代码 1 SQLITE_ERROR 2 ）：编译时：SELECT number，outletname（CASE WHEN week = WEEK1 THEN sunday ELSE 0 END）AS WK1S，（CASE WHEN week = WEEK1 THEN monday ELSE 0 END) AS WK1M,(CASE WHEN week = WEEK1 THEN thursday ELSE 0 END) AS WK1TH,(CASE WHEN week = WEEK1 THEN tuesday ELSE 0 END) AS WK1T,(CASE WHEN week = WEEK1 THEN wednesday ELSE 0 END) AS WK1W, FROMlabels5 UNION all SELECT GRANDTOTALNULLCOUNT (CASE WHEN week = WEEK1 AND sunday LIKE sunday THEN 1 END) AS WK1S,COUNT(CASE WHEN week = WEEK1 AND monday LIKE monday THEN 1 END) AS WK1M,COUNT(CASE WHEN周 = WEEK1 和星期二像星期二然后 1 结束）作为 WK1MT，计数（当周 = WEEK1 和星期四像星期四然后 1 结束时的情况）作为 WK1TH，计数（当周 = WEEK1 和星期三像星期三然后 1 结束时的情况）作为 WK1W， FROMlabels5在 android.database.sqlite.SQLiteConnection.nativePrepareStatement（本机方法）
非常不确定 rawquery 是否支持这种情况。 如果有人可以通过建议的游标查询发现亮点或任何人将不胜感激

连接 sql 代码片段时，请确保在这些片段之间包含空格或逗号，如果像"GRAND TOTAL"这样的列包含非法字符（空格），请将其括在方括号中，或者如果它是字符串文字，请将其括起来在单引号中：
String sql1 = "SELECT " +
"number as no, " +
"outletname as name, " +
"(CASE WHEN week = 'WEEK1' THEN sunday ELSE 0 END) AS WK1S, " +
"(CASE WHEN week = 'WEEK1' THEN monday ELSE 0 END) AS WK1M, " +
"(CASE WHEN week = 'WEEK1' THEN tuesday ELSE 0 END) AS WK1T, " +
"(CASE WHEN week = 'WEEK1' THEN wednesday ELSE 0 END) AS WK1W, " +
"(CASE WHEN week = 'WEEK1' THEN thursday ELSE 0 END) AS WK1T, " +
"(CASE WHEN week = 'WEEK1' THEN saturday ELSE 0 END) AS WK1SA, " +
"(CASE WHEN week = 'WEEK2' THEN sunday ELSE 0 END) AS WK2S, " +
"(CASE WHEN week = 'WEEK2' THEN monday ELSE 0 END) AS WK21M, " +

您可能错过了这些列之间的空格："labels5 UNION all SELECT GRANDTOTAL" +"NULL" + "COUNT... 尝试将其更改为："labels5 UNION all SELECT GRANDTOTAL" +"NULL" + " COUNT...
