Thanks Alex Comment from : Ezeh Confidence Adaeze

Alex often uses the expression to hit sth off of sth What does it mean? To copy? To extract? I tried to google this expression, but couldn't find anything that would apply to this context Can anyone help? Comment from : Viatic Space

Can anyone explain what the number is we put inside parenthese in fron of VARCHAR? Comment from : Maryamnaz

I don't think # is a pound sign I call it a hash sign :) Comment from : mcfunthomas

Hi Alex, kindly explain the difference between 'text' and 'varchar' and why you have to use a parenthesis right after the varchar? Comment from : Christine Onunze

What do you mean by hit off? Comment from : David Chung

Thanks for this Alex! Comment from : Anthony D

For anyone following along in postgreSQL, use TEMP or TEMPORARY to create your temporary tables Unfortunately, postgreSQL doesn't recognize the # sign in creating temp tables brEX:brbrCREATE TEMP TABLE temp_employee(bremployeeid INT,brjobtitle VARCHAR(100),brsalary INTbr); Comment from : Brandon Smith

These tutorials are amazing! Thanks so much, Alex Question: Why would a person use a temp table if it is just session-specific Why wouldn't one just create a new table using a past query so that it is stored permanently, for use later? Comment from : Carrie Goff

Liking the video even before start watching itbrThat's the faith I have on Alex Comment from : Sanil Kumar Barik

can you explain the meaning of varchar? i get the int as integer type of data, but what is varchar? why not put string? Comment from : Secret Nobody
