【推荐】2019 Java 开发者跳槽指南.pdf(吐血整理) >>> 如何编写一个存储过程，该存储过程从CSV文件导入数据并填充表？ #1楼 您也可以使用pgAdmin，它提供了一个GUI来进行导入。 这在此 SO线程中显示 。 使用pgAdmin的优点是它也适用于远程数据库。 但是，与之前的解决方案非常相似，您将需要在数据库中拥有表。 每个人都有自己的解决方案，但我通常要做的是在Excel中打开CSV，复制标题，将带有换位符的特殊内容粘贴在不同的工作表上，将相应的数据类型放在下一列中，然后将其复制并粘贴到文本编辑器中加上适当的SQL表创建查询，如下所示： CREATE TABLE my_table ( /*paste data from Excel here for example ... */ col_1 bigint, col_2 bigint, /* ... */ col_n bigint ) #2楼 一种快速的方法是使用Python pandas库（版本0.15或更高版本效果最好）。 这将为您创建列-尽管显然对数据类型所做的选择可能不是您想要的。 如果不能完全满足您的要求，则可以始终使用作为模板生成的“创建表”代码。 这是一个简单的例子： import pandas as pd df = pd.read_csv('mypath.csv') df.columns = [c

I understand that TX and XID mean transaction and transaction ID respectively, however I don't understand what the fraction notation means. 回答1: Virtual transaction IDs have the "n/nnnn" format. Real XIDs are just integers. The first part of the virtual xid is a backend identifier that's unique to each connection; the second part is a temporary transaction id assigned by that

由 强颜欢笑 提交于 2020-01-01 08:04:04
