I came across this SQL String Function few days ago while searching for Database Replication. This is T-SQL Function and it repeats the string/character expression N number of times specified in the function.
SELECT REPLICATE( ' https://blog.sqlauthority.com/ ' , 9 )
This repeats the string https://blog.sqlauthority.com/ to 9 times in result window. I think it is fun utility to generate repeated text if ever required.
Result Set:
https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/ https://blog.sqlauthority.com/
