Question

I have such postresql table:

id  user    year        id_card_no

1   john    1995        AZE546546       
2   ali     2002        464645AZE               
3   hayat   2007        4454AZE45455            
4   jack    2008        455454554

I want to get all values which have AZE word inside column (id_card_no) field. I used this query:

SELECT * FROM table_name WHERE  id_card_no LIKE '%AZE%' 

But I got first field which id is equal to 1. How can I get all columns which have AZE word inside id_card_no?

Answer 1

For doing a case insensitive LIKE you have two options:

SELECT * 
FROM table_name 
WHERE  id_card_no ILIKE '%AZE%' 

or

SELECT * 
FROM table_name 
WHERE lower(id_card_no) LIKE lower('%AZE%')
