IBATIS 2.0動態設置表名

Question

我想在Ibatis select標籤中動態設置表名。

<select id="queryGetTopSongCount" parameterClass="java.lang.String" resultClass="java.lang.Integer"> 
    SELECT 
    count(0) 
    FROM 
    #toptable# 
</select> 

查詢GetTopSongCount被稱爲下面

Map<String, Object> parameterMap = new HashMap<String, Object>(); 
parameterMap.put("toptable", "top_of_week_tab_6_2014"); 

int totalPagination=(Integer)getMainSqlMapClient().queryForObject(queryGetTopSongCount, toptable); 

我收到以下錯誤

com.ibatis.common.jdbc.exception.NestedSQLException: 
--- The error occurred in resources/ibatis/song-sqlMap.xml. 
--- The error occurred while applying a parameter map. 
--- Check the song.queryGetTopSongCount-InlineParameterMap. 
--- Check the statement (query failed). 
--- Cause: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ''top_of_week_tab_6_2014'' at line 1 

這個問題似乎是與雙引號。如何設置不帶雙引號的字符串參數？

Answer 1

而是用哈希＃toptable＃封閉參數，我們需要用美元符號$ toptable圍住它$

<select id="queryGetTopSongCount" parameterClass="java.lang.String" resultClass="java.lang.Integer"> 
    SELECT 
    count(0) 
    FROM 
    $toptable$ 
</select>
