There are many types of LOCK in database, I will write article on different types of lock very soon, right now my intention is to show which table is being locked at the moment.

But when a later ALTER TABLE command resulted in page splits and row movement, SQL Server adjusted the rows that were moving to new pages, making space for the previously added column. The ALTER TABLE command updates metadata only when SQL Server makes the following changes to a table: dropping a column or constraint, disabling a constraint, or disabling or enabling a trigger
However, today when I tried to increase a varchar column from 100 to 255 I got a nasty error: As ever, when presented with an error like this the male part of my brain that ignores the details when receiving driving directions from a stranger kicks in.

Resize or Modify a MS SQL Server Table Column with Default Constraint using T-SQL Commands
If you execute the below sample t-sql statements command by command, you can see how a column which has a default constraint can be resized or modified using t-sql. As an IT professional working on database programming I had to alter table columns to keep generally more data, so resize and modify their size length without changing the table column data type

If you have to make changes to the parameters within the definitions (like I need to) you can simply script that part into where the definitions are created again. Have you indexed the columns? Used it in a view with schemabinding? Persisted it? Foreign key relationship to it? What if the ALTER changes the datatype, NULLability or determinism?
