Hello! Today we are here for a very simple question. How to view a table in PostgreSQL? I saw this question searched on Google around 50 times each month, and want to explain answer of the question.

Well, question itself was not really clear, but i believe there can be two different options are available:

• Viewing data in a table
• Viewing a table’s structure

Since that is beginner question let’s start with a baby step.

What is a Table in PostgreSQL?

In PostgreSQL, a table acts like a digital spreadsheet, storing organized data across rows and columns. Think of it as a filing cabinet with labeled drawers (columns) holding folders (rows), each containing documents (data entries). Here’s the gist:

1. Structure: Each column defines a category of information (e.g., name, age) with a specific data type (e.g., text, number). Rows, like individual folders, hold entries for each category, making up a unique record.
2. Relationships: Tables can connect (relate) to each other, sharing data efficiently. Imagine linking folders across cabinets for broader information.
3. Queries: You can retrieve and manipulate data using commands called queries. Think of it as searching and organizing your filing cabinet based on specific criteria.
4. Benefits: Tables keep data organized, easily searchable, and manageable, making them essential building blocks for any PostgreSQL database.

In just 100 words, that’s the essence of tables in PostgreSQL! Remember, there’s much more to explore, but this should give you a solid starting point.

Data: How to View a Table in PostgreSQL?

Most of the relational database engines such as PostgreSQL has an interactive method to communicate. We call structured sentences we use to communicate with PostgreSQL as a statement. We call viewing a data as querying a table.

To view data in a table in PostgreSQL we need to write a select statement.

SELECT * FROM jtest;

SELECT and FROM are the keywords we use, * is used as a wildcard to select all columns and jtest is the name of the table.

Table Structure: How to View a Table in PostgreSQL?

Each table should have a structure. Most relational database engines need structured tables. Table structures can be changed using statements.

PostgreSQL’s interactive command line psql can be used to display structure of a table:
