Create random string using the function NEWID, this will give us a random 36 characters string. Clean the dash character, this will give us a random 32 characters string. Create a random number using the function NEWID, as the string length. Cut the string using the function LEFT...
A constant integer expression used by SQL Server to generate a random number. repeat_seed is bigint. If repeat_seed isn't specified, SQL Server assigns a value at random. For a specific repeat_seed value, the sampling result is always the same if no changes have been applied to the tabl...
