插入類目記錄,並返回category_id,其中category_id是根據自定義規則生成的
<insert id="insertSelective2" parameterType="com.imooc.model.ProductCategory"> insert into product_category(<include refid="Base_Save_List"/>) values (#{productCategory.categoryName,jdbcType=VARCHAR},#{productCategory.categoryType,jdbcType=INTEGER}) <selectKey keyProperty='productCategory.categoryId' resultType='int' order='AFTER' > select MAX(category_id) from product_category </selectKey> </insert>
使用方法
public Integer save(ProductCategory productCategory) {
System.out.println(categoryMapper.insertSelective2(productCategory));
int categoryId = productCategory.getCategoryId;
return categoryId;
}
上述程式碼實現了將MAX(category_id)存入'productCategory.categoryId,供大家參考
