Most of the content is all the way to next

Installation path settings

Additional function software settings

Installation path settings

Set password

Port number

Language

Then click all the way to complete the installation

To operate with cmd, initialize the database and start the server

cd to the corresponding directory

Using commands

initdb.exe -D D:\postgresql 14\data -E UTF-8 --locale=chs -U postgres -W3

If the directory contains spaces, it may prompt an error

This time use the following

initdb.exe -D "D:\postgresql 14\data" -E UTF-8 --locale=chs -U postgres -W3

In the middle, the password of the super user will be entered, and you can enter it by yourself

There is a command to start the database in the prompt:

pg_ctl -D "D:\postgresql 14\data" -l logfile start

It should be able to go down normally, but I reported an error here, indicating that access is denied

In this case, enter the command

pg_ctl.exe start -D ..\data

Generally speaking, it is ok. If it still doesn't work, it may be the permission problem of the data folder. You need to see if the permission is missing.

Open the installed pgadmin, the path is not difficult to find

After opening the application, you can set the Chinese language first

Then you can create a new server

The local word is 127.0.0.1, and the rest should be understandable in Chinese. You can enter the address and password without changing the account number.

You can use Navicat to connect after creation

Navicat's connection will not take screenshots, everyone who has used it knows where it comes from

Try if it works for yourself

CREATE table test_1(test VARCHAR(50),test1 VARCHAR(50));INSERT INTO test_1(test,test1)VALUES('qqq','www');select * fromtest_1

If it can be found out, it should be no problem, but basically there should be no problem at this stage

It is estimated that the syntax is a bit different from oracle, and you can take a closer look when you have time

You can also query through pgadmin
