Why should I capitalize my SQL keywords?

hi,

I’m pretty new to SQL, but i’ve noticed that writing

SELECT * FROM column_name

is almost always used when

select * from column_name

yields exactly the same result. I can’t find anything online about this. Is this just a convention? Or will not using uppercase break the script on older systems/systems that i’m not aware of?

thanks

SQL was developed in the 1970s when the popular programming languages (like COBOL) used ALL CAPS, and the convention must have stuck.
