我正在使用以下命令更新数据库中的表：

public long UpdateIncomeDB(String item,String price,String update) throws SQLException
{
    ContentValues initialValues = new ContentValues();
    initialValues.put(KEY_DESC, item);
    initialValues.put(KEY_INCOME, price);
    initialValues.put(KEY_TOTAL, price);
    db.update(DATABASE_TABLE, initialValues, "description" + "=" +update, null);
    return 0;
}

但是显示特定列不存在的错误..但是我检查了具有该列条目的数据库..请帮助我..

我的日志是：

使用这个 where 子句："description='" +update + "'"

SQL 查询中的所有 String 值都应该用 ' 四舍五入

将更新值放在引号内

"description" + "=" +update

放引号

"description" + "=" +"'"+update+"'"
