创建一个表，并拥有用于在CSV文件中创建表所需的列。

打开postgres，右键单击要加载的目标表。在文件选项部分中选择导入和更新以下步骤 现在浏览文件查找文件名 选择CSV格式 编码为ISO_8859_5

现在去Misc。选项。检查标题并单击导入。

这是我个人使用PostgreSQL的经验，我还在等待更快的方法。

Create a table skeleton first if the file is stored locally: drop table if exists ur_table; CREATE TABLE ur_table ( id serial NOT NULL, log_id numeric, proc_code numeric, date timestamp, qty int, name varchar, price money ); COPY ur_table(id, log_id, proc_code, date, qty, name, price) FROM '\path\xxx.csv' DELIMITER ',' CSV HEADER; When the \path\xxx.csv file is on the server, PostgreSQL doesn't have the permission to access the server. You will have to import the .csv file through the pgAdmin built in functionality. Right click the table name and choose import.

如果您仍然有问题，请参考本教程:导入CSV文件到PostgreSQL表

使用下面的SQL代码:

copy table_name(atribute1,attribute2,attribute3...)
from 'E:\test.csv' delimiter ',' csv header

header关键字让DBMS知道CSV文件有一个带有属性的头。

如何将CSV文件数据导入PostgreSQL表

步骤:

Need to connect a PostgreSQL database in the terminal psql -U postgres -h localhost Need to create a database create database mydb; Need to create a user create user siva with password 'mypass'; Connect with the database \c mydb; Need to create a schema create schema trip; Need to create a table create table trip.test(VendorID int,passenger_count int,trip_distance decimal,RatecodeID int,store_and_fwd_flag varchar,PULocationID int,DOLocationID int,payment_type decimal,fare_amount decimal,extra decimal,mta_tax decimal,tip_amount decimal,tolls_amount int,improvement_surcharge decimal,total_amount ); Import csv file data to postgresql COPY trip.test(VendorID int,passenger_count int,trip_distance decimal,RatecodeID int,store_and_fwd_flag varchar,PULocationID int,DOLocationID int,payment_type decimal,fare_amount decimal,extra decimal,mta_tax decimal,tip_amount decimal,tolls_amount int,improvement_surcharge decimal,total_amount) FROM '/home/Documents/trip.csv' DELIMITER ',' CSV HEADER; Find the given table data select * from trip.test;

这里的大多数其他解决方案都要求您提前/手动创建表。这在某些情况下可能不实用(例如，如果目标表中有很多列)。因此，下面的方法可能会派上用场。

提供你的CSV文件的路径和列数，你可以使用下面的函数来加载你的表到一个临时表，它将被命名为target_table:

假设第一行具有列名。

create or replace function data.load_csv_file
(
    target_table text,
    csv_path text,
    col_count integer
)

returns void as $$

declare

iter integer; -- dummy integer to iterate columns with
col text; -- variable to keep the column name at each iteration
col_first text; -- first column name, e.g., top left corner on a csv file or spreadsheet

begin
    create table temp_table ();

    -- add just enough number of columns
    for iter in 1..col_count
    loop
        execute format('alter table temp_table add column col_%s text;', iter);
    end loop;

    -- copy the data from csv file
    execute format('copy temp_table from %L with delimiter '','' quote ''"'' csv ', csv_path);

    iter := 1;
    col_first := (select col_1 from temp_table limit 1);

    -- update the column names based on the first row which has the column names
    for col in execute format('select unnest(string_to_array(trim(temp_table::text, ''()''), '','')) from temp_table where col_1 = %L', col_first)
    loop
        execute format('alter table temp_table rename column col_%s to %s', iter, col);
        iter := iter + 1;
    end loop;

    -- delete the columns row
    execute format('delete from temp_table where %s = %L', col_first, col_first);

    -- change the temp table name to the name given as parameter, if not blank
    if length(target_table) > 0 then
        execute format('alter table temp_table rename to %I', target_table);
    end if;

end;

$$ language plpgsql;
