Great post, I’m trying to comprehend the TABLESAMPLE section. Do you have a lot more belief about this? How come, I’m asking is the fact We pointed out that the Hallengren script, is determined to perform because the “upgrade statistics TableName indexName… and I’m contrasting it using my own script… In my own script with regards to the quantity of rows the fresh new dining table has, We ple, If i had a desk one 120M rows, I would ple 3M rows. My personal way takes more time than just letting SQL opt for the sampling since the Hallengren really does. I attempted to perform this new inquire that you have in the TABLESAMPLE section but didn’t obtain it to operate… Any tip?
