Method Detail

insert

public String insert(org.apache.ibatis.mapping.MappedStatement ms)

插入全部,这段代码比较复杂,这里举个例子 CountryU生成的insert方法结构如下：

 <bind name="countryname_bind" value='@java.util.UUID@randomUUID().toString().replace("-", "")'/>
 INSERT INTO country_u(id,countryname,countrycode) VALUES
 <trim prefix="(" suffix=")" suffixOverrides=",">
 <if test="id != null">#{id,javaType=java.lang.Integer},</if>
 <if test="id == null">#{id,javaType=java.lang.Integer},</if>
 <if test="countryname != null">#{countryname,javaType=java.lang.String},</if>
 <if test="countryname == null">#{countryname_bind,javaType=java.lang.String},</if>
 <if test="countrycode != null">#{countrycode,javaType=java.lang.String},</if>
 <if test="countrycode == null">#{countrycode,javaType=java.lang.String},</if>
 </trim>
 

Parameters:

ms - MappedStatement

Returns:

the string

insertSelective

public String insertSelective(org.apache.ibatis.mapping.MappedStatement ms)

插入不为null的字段,这段代码比较复杂,这里举个例子 CountryU生成的insertSelective方法结构如下：

 <bind name="countryname_bind" value='@java.util.UUID@randomUUID().toString().replace("-", "")'/>
 INSERT INTO country_u
 <trim prefix="(" suffix=")" suffixOverrides=",">
 <if test="id != null">id,</if>
 countryname,
 <if test="countrycode != null">countrycode,</if>
 </trim>
 VALUES
 <trim prefix="(" suffix=")" suffixOverrides=",">
 <if test="id != null">#{id,javaType=java.lang.Integer},</if>
 <if test="countryname != null">#{countryname,javaType=java.lang.String},</if>
 <if test="countryname == null">#{countryname_bind,javaType=java.lang.String},</if>
 <if test="countrycode != null">#{countrycode,javaType=java.lang.String},</if>
 </trim>
 

这段代码可以注意对countryname的处理

Parameters:

ms - MappedStatement

Returns:

the string
