这篇“前端传参数进行Mybatis调用mysql存储过程执行返回值实例分析”文章的知识点大部分人都不太理解，所以小编给大家总结了以下内容，内容详细，步骤清晰，具有一定的借鉴价值，希望大家阅读完这篇文章能有所收获，下面我们一起来看看这篇“前端传参数进行Mybatis调用mysql存储过程执行返回值实例分析”文章吧。
查询数据库中的存储过程：
方法一：
select `name` from mysql.proc where db = 'your_db_name' and `type`; = 'PROCEDURE'
方法二：
show procedure status;
你要先在数据库中建一个表，然后创建存储过程
我建的表a_tmp,存储过程名称bill_a_forbusiness
执行语句： CALL bill_a_forbusiness(44,44,52,47,44,46,52,52,349171)
存储过程调用方式：
CALL Pro_Get_CO2('2018','','','');
CALL Pro_Get_EnergyData('2017');
CALL Pro_Get_Carbon_OrgType('2014');
CALL 存储过程名(参数);查看存储过程或函数的创建代码：
show create procedure proc_name; show create function func_name;
因为这个没有返回值所以需要先传参调用执行，再查询
前端代码：
<template> <div class="app-container"> <el-form :model="queryParams" ref="queryForm" :inline="true" v-show="showSearch" label-width="68px" > <el-form-item label="参数输入" prop="a"> <el-input v-model="queryParams.a" placeholder="请输入第一参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="b"> <el-input v-model="queryParams.b" placeholder="请输入第二参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="c"> <el-input v-model="queryParams.c" placeholder="请输入第三参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="d"> <el-input v-model="queryParams.d" placeholder="请输入第四参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="e"> <el-input v-model="queryParams.e" placeholder="请输入第五参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="f"> <el-input v-model="queryParams.f" placeholder="请输入第六参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="g"> <el-input v-model="queryParams.g" placeholder="请输入第七参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="h"> <el-input v-model="queryParams.h" placeholder="请输入第八参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="参数输入" prop="abc"> <el-input v-model="queryParams.abc" placeholder="请输入第九参数" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <!-- <el-form-item label="录入人" prop="userName"> <el-input v-model="queryParams.userName" placeholder="请输入办理人名字" clearable size="small" @keyup.enter.native="handleQuery" /> </el-form-item> <el-form-item label="操作日期" prop="recordDate"> <el-date-picker clearable size="small" v-model="queryParams.recordDate" type="date" value-format="yyyy-MM-dd" placeholder="选择操作日期"> </el-date-picker> </el-form-item> --> <el-form-item> <el-button type="primary" icon="el-icon-top-right" size="mini" @click="handleQuery" >传值/执行</el-button > <el-button icon="el-icon-refresh" size="mini" @click="resetQuery" >重置</el-button > <el-button type="primary" icon="el-icon-search" size="mini" @click="returnQuery" >返回/查询</el-button > </el-form-item> </el-form> <el-row :gutter="10" class="mb8"> <right-toolbar :showSearch.sync="showSearch" @queryTable="getProcList" ></right-toolbar> </el-row> <el-table v-loading="loading" :data="returnprocList" @selection-change="handleSelectionChange" > <!-- <el-table-column type="selection" width="55" align="center" /> --> <el-table-column label="序号" align="center" prop="" type="index" width="60" /> <el-table-column label="记录id" align="center" prop="Id" /> <el-table-column label="第一参数趟次" align="center" prop="a" width="200" /> <el-table-column label="第二参数趟次" align="center" prop="b" /> <el-table-column label="第三参数趟次" align="center" prop="c" /> <el-table-column label="第四参数趟次" align="center" prop="d" /> <el-table-column label="第五参数趟次" align="center" prop="e" /> <el-table-column label="第六参数趟次" align="center" prop="f" /> <el-table-column label="第七参数趟次" align="center" prop="g" /> <el-table-column label="第八参数趟次" align="center" prop="h" /> <el-table-column label="趟次总金额" align="center" prop="abc" /> <!-- 刷新查询 --> <pagination v-show="total > 0" :total="total" :page.sync="queryparameters.pageNum" :limit.sync="queryparameters.pageSize" @pagination="getProcList" /> </template>
