把excel数据导入pgAdmin3

Posted 2020-08-22 下一个秋天

1.安装perl软件，安装完配置环境变量：在系统变量的path路径后加入perl/bin的文件路径，用；号分隔、结尾

2.把data(不带字段的数据）跟perl的语句放在E盘；以下perl语句创建表

#!/usr/bin/perl -w
use strict;

my $host = ‘localhost‘;
my $port = ‘5432‘;
my $db = ‘test1‘;//在数据库中新建test数据库
my $user = ‘postgres‘;

my $connect_string = "psql -a -h $host -d $db -U $user";

my $cre_string=‘acct_no varchar(50),

open(PSQL,"|$connect_string");
print PSQL<<ENDPSQL;
set client_encoding =GBK;
--drop schema src cascade;
--drop schema temp cascade;

CREATE TABLE stage.acct_6_30($cre_string);//新建stage模式
copy acct.acct1 from ‘E:/data/acct1.csv‘
with delimiter ‘,‘ null ‘‘;

ENDPSQL
close(PSQL);

　　再用  cmd控制台执行以下代码

1.C/D/E/F://找到perl语句脚本的根目录
2.cd perl1//找到perl文件夹
1.perl//执行1.perl的pl文件

最后在数据库中刷新，看看是否新建表
