Hello, When I run this T-SQL script that begins a dynamic way to create table partitions, I’m fine until the last step of resetting the Counter back to 0 and get that error. It seems syntactically fine and makes
sense and is needed before it goes to the next block of codes, which all also have this same counter reset to 0. I’ve tried redeclaring, omitting it, mod the syntax, but nothing I do works and I always error. What can I try or rewrite with this design? Thanks
