# so the scenario is we have table called employees
# in employees table there is column called department 
# there are different departments are included in table
# now we want some department which we dont know how its spelled there so we are just
# trying to fetch the data in column which matched or containes 
# ex: word 'Clothing' is in stored in table but we dont know exactly how data spelled there
# so we try to match something like '% clo %'
# or 'C% thing %'

SELECT * FROM emploees  WHERE department like '% thing %';
# or 
SELECT * FROM employees WHERE department like 'C% thing %';

# here we use WHERE column_name but we don't know what is the data 
# To fetch result of given string to match in column_data we use LIKE
#syntax SELECT * FROM <table-name> WHERE <column_name> LIKE '%<data-to-fetch>%' with out
#space both sides

SELECT * FROM employees WHERE department LIKE '%Clo%';
# NOTE : %Clo% is departement feches related data which start with that string

#ref below
course_data=# SELECT * FROM employees WHERE department LIKE '%Clo%' LIMIT 10;
