whenever I am trying to create a new table on PgAdmin 4 tool for postgresql I am getting an error
Query: CREATE TABLE geeks_table
ERROR: syntax error at end of input LINE 1: CREATE TABLE geeks_table ^ SQL state: 42601 Character: 25
As per the comments, you need to add the data definition language (DDL) to the create statement.
The database needs to know what columns and data types are required, for example, the following DDL will create a 2 column table:
CREATE TABLE geeks_table (
code INTEGER PRIMARY KEY,
title varchar(40) NOT NULL
);
If you're aiming for a table without columns, this is the syntax
CREATE TABLE geeks_table ();
