This might help you I need to pass the database name via a parameter in a hashmap. , You need to use ${} instead of #{} for direct String substitution.
code :
<select id="getById" parameterType="hashmap" resultMap="result">

I hope this helps you . You have to use a TypeHandler. That's how MyBatis sets Java types set into Prepared and Callable Statements.
If you register the TypeHandler with your MyBatis configuration, then MyBatis will choose the correct type handler automatically, avoiding typing "typeHandler=..." in the sql map. That's how you can get it to use javaType variable to find your type handler.
code :
configuration.getTypeHandlerRegistry().register(HashMap.class, new MyPLSQLTypeHandler());

To fix the issue you can do I'm new to to MyBatis. I'm using mybatis 3.1.1 version as DAO implementation. , I found my mistake.
I included sql statement into CDATA
code :
 <select id="getLastMassPaymentRecords" resultType="MassPaymentFile" parameterType="map" >
        FROM mass_payment_protocol
       WHERE user_id=#{user_id} AND rownum<=#{count}
       ORDER BY created desc

Hope this helps ${} doesn't support the parameter index according to my test. You can use Param annotation to specify the parameter name in your mapper API declaration.
code :
public MatchResult get(long id, @Param("tablename") String tablename);
<select id="get" resultType="myresult">
    select * from ${tabelname} where id=#{0}
public MatchResult get(Map<String, Object> params);
<select id="get" parameterType="map" resultType="myresult">
    select * from ${tablename} where id=#{id}
Cannot get the result by passing the parameter to MyBatis

To fix this issue When you pass a single parameter object, properties are accessed directly through getter or key set for a map. When you want to pass multiple parameters in the method, you have to name the parameters with annotation:
code :
Configuration findByKeyAndUserId(@Param("key") String key, @Param("userId") Long userId);
