Insert value to auto increment colomn

[ghjk]

I'm a new to postgres. i have a table which is having a colomn with auto increment value. When I insert value to that table, it gives an error.

$pgsql = "INSERT INTO xxx VALUES (null,'$FullName', '$DoB', '$Address','$PhnNo' )";

Error in SQL query: ERROR: null value in column "No" violates not-null constraint

First column is the auto increment one.
Could some one help me?

If it is autoincrement column, why do yo want to put a value here. Let postgres put this value, unless you have a good reason to put value by yourself.

To let postgres to put a value write

$pgsql = "INSERT INTO xxx(HERE WRITE COMMA-SEPARATED COLUMNS WICH YOU FILL WITH VALUES) VALUES ('$FullName', '$DoB', '$Address','$PhnNo' )"; 
 

for example

$pgsql = "INSERT INTO xxx(full_name,some_column,address,phone) VALUES ('$FullName', '$DoB', '$Address','$PhnNo' )";
