SQLite中的撇号选择查询

Question

我有SQLite的问题和一些定制的SQL:

public Cursor getExistingSpeciesDetails(String sub_id, String english_name) {
    Cursor c = mDb.rawQuery(
            "SELECT mobileobs.how_many, mobileobs.comment, mobileobs.sensitive, "
                    + "mobileobs.breeding_evidence from mobileobs "
                    + "WHERE mobileobs.sub_id = '" + sub_id
                    + "' and mobileobs.english_name = '" + english_name
                    + "'", null);
    return c;
}

我的问题是英文名称中的撇号(Cetti's Warbler)导致SQL中的错误(强制关闭我的Android应用程序).在这种类型的条款中有没有办法逃避撇号？

提前致谢

Answer 1

为此,您需要使用SQLIte的参数注入.例如:

Cursor c = mDb.rawQuery(
            "SELECT mobileobs.how_many, mobileobs.comment, mobileobs.sensitive, "
             + "mobileobs.breeding_evidence from mobileobs "
             + "WHERE mobileobs.sub_id = ? AND mobileobs.english_name = ?"
             , new String[]{sub_id, english_name});

或者更改输入参数如下:

Cetti''s Warbler
