Android 无法在请求的上下文中使用函数匹配

在方法getContactMatches（）中，sql语句出错 字符串选择=列名称+“匹配？”；我不太熟悉sql，所以我不知道该怎么办

数据库类和getContactMatches（）方法：

12-27 22:00:25.622:E/SQLiteLog（642）：（1）语句在7处中止：[从contactsTable中选择*WHERE（名称匹配？）]无法在请求的上下文中使用函数匹配12-27 22:00:25.622:E/SQLiteQuery（642）：异常：无法在请求的上下文中使用函数匹配（代码1）；查询：从contactsTable中选择*（姓名匹配？）哦，我的错。我想我的身份证号码每次问问题都会重置。我会确保下次添加。这种类型的查询过去是有效的，但看起来如果匹配发生在一个连接中，那么它只能发生在一个连接中
