### **MyBatis** 通过包含的jdbcType**类型** ###

BIT         FLOAT      CHAR           TIMESTAMP       OTHER       UNDEFINED  
  
TINYINT     REAL       VARCHAR        BINARY          BLOB        NVARCHAR  
  
SMALLINT    DOUBLE     LONGVARCHAR    VARBINARY       CLOB        NCHAR  
  
INTEGER     NUMERIC    DATE           LONGVARBINARY   BOOLEAN     NCLOB  
  
BIGINT      DECIMAL    TIME           NULL            CURSOR

### **Mybatis**中**javaType**和**jdbcType**对应和CRUD例子 ###

     2   <result property="FLD_NUMBER" column="FLD_NUMBER"  javaType="double" jdbcType="NUMERIC"/>
     3   <result property="FLD_VARCHAR" column="FLD_VARCHAR" javaType="string" jdbcType="VARCHAR"/>
     4   <result property="FLD_DATE" column="FLD_DATE" javaType="java.sql.Date" jdbcType="DATE"/>
     5   <result property="FLD_INTEGER" column="FLD_INTEGER"  javaType="int" jdbcType="INTEGER"/>
