时，查询用例生成SQlite列表视图。
提问于 2019-11-29 18:24:10
尝试在Android中显示sqlite信息，在DB浏览器中进行了测试，测试结果显示出了预期的结果，但我无法在安卓系统中实现。
实表如下所示：
Sqlite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 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,

错误：
由：GRANDTOTALNULLCOUNT (代码1 SQLITE_ERROR2)：，编译时:选择number，outletname (当while = WEEK1，然后再使用周日SQLITE_ERROR 0 END)为WK1S，(当WHEN = WEEK1，再周一SQLITE_ERROR 0结束时)为WK1M，(当week = WEEK1，然后再到周四SQLITE_ERROR 0结束时)为WK1TH，(当week = WEEK1，然后星期二number 0结束时)为WK1T，(当while= WEEK1，然后周三number 0结束时)为WK1W，在android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native方法中，FROMlabels5 UNION都选择GRANDTOTALNULLCOUNT(当星期= WEEK1，周日像周日，然后1结束)为WK1S，计数(当星期= WEEK1，星期一像星期一，然后1结束)为WK1M，计数(当星期= WEEK1，星期二像星期二，然后是1结束)为WK1MT，计数(当星期= WEEK1，星期四像星期四，第1结束)为WK1TH，计数(当星期= WEEK1，星期三像星期三，然后结束)为WK1W，FROMlabels5在WK1MT。
对于rawquery是否支持这个场景非常不确定。如果有人能用建议光标查询来识别光线，或任何其他人都会非常感激。

当您连接一些sql代码时，请确保在这些代码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)，将其括在方括号中，或者如果它是字符串，则用单引号将其括起来：
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, " +
"(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, " +

"FROM labels5";Stack Overflow用户

您可能遗漏了这些列之间的空格："labels5 UNION all选择GRANDTOTAL“+"NULL”+ COUNT .尝试将其更改为："labels5 UNION all选择GRANDTOTAL“+"NULL”+ "COUNT .
