的Android SQlite的遊標查詢錯誤

Question

String Where = "SELECT FROM peopleTable WHERE _id BETWEEN " + i1+ " AND " + i2; 

哪裏錯了嗎？ logcat的：

12-18 16:47:54.497: E/SQLiteLog(2447): (1) near "SELECT": syntax error 
12-18 16:47:54.757: E/AndroidRuntime(2447): FATAL EXCEPTION: main 
12-18 16:47:54.757: E/AndroidRuntime(2447): android.database.sqlite.SQLiteException: near "SELECT": syntax error (code 1): , while compiling: SELECT _id, persons_name, persons_hotness FROM peopleTable WHERE SELECT FROM peopleTable WHERE _id BETWEEN 2 AND 4 

Answer 1

您正在使用內另一個SELECT這就是爲什麼它給一個語法錯誤，不是因爲BETWEEN子句SELECT代替

SELECT _id, 
persons_name, 
persons_hotness FROM 
peopleTable WHERE SELECT 
FROM peopleTable WHERE 
_id BETWEEN 2 AND 4 

使用此查詢

SELECT _id, 
persons_name, 
persons_hotness FROM 
peopleTable WHERE 
_id BETWEEN 2 AND 4 



db.query("peopleTable", 
new String[] {_id, person_name,    person_hotness}, 
"WHERE _id BETWEEN 2 AND 4",  null, null, null, null);
