Question

我正在尝试更新Sqlite（android）中的列，但日志显示以下错误。有人可以帮我解决一下吗？

06-11 12:52:21.373: I/Database(355): sqlite returned: error code = 1, msg = near "@gmail": syntax error
06-11 12:52:21.373: E/Database(355): Error updating password=12345 using UPDATE user SET password=? WHERE COL_USERID = something@gmail.com

这是我的代码：

public long updateUserPassword(String userid, String password) {
    ContentValues initialValues = 
            createUserPasswordContentValues(password);

    return database.update(LOGIN_TABLE, initialValues, "COL_USERID = "+userid, null);
}

private ContentValues createUserPasswordContentValues(String password) {
    ContentValues values = new ContentValues();
    values.put(COL_PASSWORD, password);
    return values;
}

Answer 1

缺少单引号。使用以下代码

return database.update(LOGIN_TABLE, initialValues, "COL_USERID = '"+userid+ "'", null);

Answer 2

替换以下行：

return database.update(LOGIN_TABLE, initialValues, "COL_USERID = '"+userid+"'", null);

而不是：

return database.update(LOGIN_TABLE, initialValues, "COL_USERID = "+userid, null);

Answer 3

"COL_USERID = "+userid中缺少单引号，请使用此"COL_USERID = '" + userid + "'" 即简单地说，改变这个

   return database.update(LOGIN_TABLE, initialValues, "COL_USERID = "+userid, null);

到

return database.update(LOGIN_TABLE, initialValues, "COL_USERID = '" + userid + "'", null);

sqlite返回：错误代码= 1，msg =接近“.....”：语法错误
