之前在用MyBatis的时候没用过表名作为参数,最近使用到了. 基于注释使用MyBatis的Dao层代码如下: @Repository public interface Base1102Dao { @Select(value = "Select * from ${table_name} order by id") @ResultType(HashMap.class) List<HashMap> getAll(@Param("table_name") St
表名作为参数的动态游标 DECLARE v_table_name VARCHAR2(30) := 'CUX_MES_WIP_BARCODE_MAP'; --l_rec SYS_REFCURSOR; TYPE t_data IS TABLE OF VARCHAR2(30) INDEX BY BINARY_INTEGER; TYPE t_cur IS REF CURSOR; l_data t_data; l_rec t_cur; l_cur VARCHAR2(4000); v_fm_barcode
有以下存储过程: CREATE DEFINER=`root`@`localhost` PROCEDURE `P_HoverTreePages`( ), ) , ), ), ), IN `SortType` INT, IN `RecorderCount` INT, IN `PageSize` INT, IN `PageIndex` INT, OUT `TotalCount` INT, OUT `TotalPageCount` INT ) LANGUAGE SQL NOT DETERMINISTIC
参数获取 之前我们都是采用#{}的方式进行参数传递,其实MyBatis还有另外的参数传递方式${} 使用方法相同,但是还是有很大区别的 这里做一个测试: <select id="getEmpByMap" resultType="com.figsprite.bean.Employee"> select id,last_name lastName,gender,email from tb_employee where id = ${id} and
1. 用数组元素作函数实参 #include <iostream> using namespace std; int max_value(int x, int max) { return max > x ? max : x; } int main() { , y = ; ,,,},{,,,},{,,,}}; ][], i, j, ix, iy; ; i < x; i ++) { ; j < y; j++) { max = max_value(a[i][j],max); if(
mybatis 查询 xml list参数: <select id="getByIds" resultType="string" parameterType="java.util.List"> SELECT a.FENLEINAME from Tab a where a.id in (select b.pid from TB b where b.id in <foreach collection="list"
表名作为參数的动态游标 DECLARE v_table_name VARCHAR2(30) := 'CUX_MES_WIP_BARCODE_MAP'; --l_rec SYS_REFCURSOR; TYPE t_data IS TABLE OF VARCHAR2(30) INDEX BY BINARY_INTEGER; TYPE t_cur IS REF CURSOR; l_data t_data; l_rec t_cur; l_cur VARCHAR2(4000); v_fm_barcode
Mybatis找不到参数错误:There is no getter for property named 'categoryId' in 'class java.lang.Integer'. 错误List<Post> listPage(Integer categoryId);在测试时报错:There is no getter for property named 'categoryId' in 'class java.lang.Integer' 问题分析:Mybatis默认采用ONGL解析参数
