How to view the create table statement in PostgreSQL?
In PostgreSQL, you can use the \d+ command to view the create table statement of a specified table.
The specific steps are as follows:
- Open the command line interface of PostgreSQL or use graphical interface tools like pgAdmin to connect to the database.
- Enter the following command in the command line interface to view the creation statement of the table:
- Table name consisting of one or more digits.
- The table name is the name of the table for which the create table statement is being viewed.
- After executing the command, the table’s create table statement will be displayed, including information such as the table’s name, column definitions, and constraints.
- The example output is as follows:
- Table “public.table_name”
Column | Type | Collation | Nullable | Default | Storage | Stats target | Description
————+———+———–+———-+———+———-+————–+————-
id | integer | | not null | | plain | |
name | text | | | | extended | |
created_at | date | | | | plain | |
updated_at | date | | | | plain | |
Indexes:
“table_name_pkey” PRIMARY KEY, btree (id) - The above example output contains information such as the table name, column definitions, and indexes.
Important notes:
- To use the \d+ command, you need to have read access to the table being queried.
- If the command \d+ does not work in the command line interface, you can try using the \d table_name command to view the structure of the table.
