我有2个 FTS 表:搜索和 search_eng 。我想从 search_eng 获取匹配字词的 entry_id 。然后我根据 entry_id 从搜索中获取值。但是,当我尝试使用下面显示的方式时,它给出了错误: SQL逻辑错误。 这是因为 MATCH 超过2个值?如果不是我做错了什么?
//takes entry_id, g_value where matches word
query = "SELECT * FROM search_eng WHERE g_value MATCH '"
+ lookingFor + "' LIMIT 10";
cursor = db.rawQuery(query, null);
if (cursor.moveToFirst()) {
//if cursor is not empty
int num = 0;//counter for loop
query = querySelectFromTableWhere;//"SELECT entry_id AS _id, re_value, ke_value, g_value, pos FROM search WHERE "
do {
if (num == 0) {
//for the first time
//query for getting all data of words which matches with entry_id which was got from search_eng
query = query
+ " entry_id MATCH '"
+ cursor.getString(cursor
.getColumnIndex("entry_id"))+"'";
} else {
//next tries: 2nd time, 3rd time...
//query for getting all data of words which matches with entry_id which was got from search_eng
query = query
+ " OR entry_id MATCH '"
+ cursor.getString(cursor
.getColumnIndex("entry_id"))+"'";
}
num++;//plus counter
} while (cursor.moveToNext());
query=query+" LIMIT 10";
}

请参阅sqlite
文档here。
要匹配多个字词,您必须在字词之间添加OR
,而不是MATCH
es。类似的东西:
SELECT entry_id AS _id, re_value, ke_value, g_value, pos
FROM search
WHERE entry_id MATCH 'firstWord OR secondWord`
是的,或者在''
内。
