Android sql 查询中的异常在 DB Browser 中运行正常

Question

当运行下面的查询在Android

select * 
from EICRChecklistItems 
where (Sect, S_Sect, SS_Sect) in (
  select Sect, S_Sect, SS_Sect 
  from EICRCheckList 
  where Version=2018 
  order by id
) 
order by id

我得到异常：

android.database.sqlite.SQLiteException: near ",": syntax error (code 1)

列 Sect、S_Sect 和 SS_Sect 都定义为 integer。

但是当运行在 DB Browser 上针对同一数据库的副本时它会正确执行

任何关于可能导致此问题的指示都将不胜感激。

private var EICR_CHECK_ITEMS_TABLE = "EICRChecklistItems"
private var EICR_CHECKLIST_TABLE = "EICRCheckList"
val cursor1: Cursor = writableDatabase.rawQuery(
            "select * from $EICR_CHECK_ITEMS_TABLE where (Sect, S_Sect, SS_Sect) in (select Sect, S_Sect, SS_Sect from $EICR_CHECKLIST_TABLE where Version='2018' order by id) order by id",  null)

Answer 1

由于您的 SQLite 版本早于 3.15.0，您不能使用 ROW VALUES，您可以使用 EXISTS 代替运算符 IN:

SELECT ei.* 
FROM EICRChecklistItems ei 
WHERE EXISTS (
  SELECT 1 FROM EICRCheckList el
  WHERE el.Version = 2018
  AND el.Sect = ei.Sect AND el.S_Sect = ei.S_Sect AND el.SS_Sect = ei.SS_Sect
)
ORDER BY ei.id

请注意，代码中子查询中的 ORDER BY 子句实际上没有用。
