csv文件批量导入数据到sqlite. 代码: f = web.input(bs_switch = {}) # bs_switch 为from表单file字段的namedata =[i.split(",") for i in f["bs_switch"].file.read().split()[1:]] #这里的步骤: #1.读取导入的内容:f["bs_switch"].file.read() #2.因为导入的内容为str,转化为列表.用spl
一.将ACCESS表导出为CSV文件:Select * INTO [TEXT;FMT=CSV;DELIMITED;HDR=YES;DATABASE=E:\temp\].test.csv FROM Sheet2; 二.导入CSV文件并生成新的ACCESS表:Select * INTO test FROM [TEXT;FMT=CSV;DELIMITED;HDR=YES;DATABASE=e:\Temp\].[test.csv]; 三.将CSV文件追加到现有的ACCESS表中:Insert INTO
导出例子: select *from testinto outfile 'D:test.csv'fields terminated by ',' optionally enclosed by '"' escaped by '"'lines terminated by '\r\n';导入例子:load data infile 'D:test.csv' into table `test` fields terminated by ',' optionally enclosed by '&q
封装处理下,以后项目用到可以直接使用,比较简单. 1.首先看封装好的类 using System; using System.Data; using System.IO; using System.Text; using CSharpUtilHelpV2; using StringUtilHelp; namespace DBUtilHelpV2Plus { public static class DBToolV2Plus { /// <summary> /// 将DataTable导出到CSV
在工作中需要把csv文件数据导入数据库或者把数据库数据导出为csv文件.以下是我的简单的实现. <?php class csv { public $db_connection; public $table_name; public $file_path; public function __construct($db_connection,$table_name,$file_path) { $this->db_connection=$db_connection; $this->table
项目中用到含有中文字段的数据CSV文件,导入Mysql数据中发现中文内容乱码. 分析原因:因为数据库字符编码问题引起. [1]创建utf-8字符集数据库 CREATE DATABASE db_name DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; [2]更改数据库的字符编码 ALTER DATABASE db_name DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci; 如上,更改了数据
一.导出到csv(本地导出) 通过mysql客户端shell连接到服务器,选择使用的数据库,输入sql代码: select * from test_info into outfile '/tmp/test.csv' fields terminated by ',' ------字段间以,号分隔 optionally enclosed by '"' ------字段用"号括起 escaped by '"' ------字段中使用的转义符为" lines term
