Dynamics SL 2011 - reading from syscolumns table

Newbie here,

I am trying to find out why we sometimes have a bunch of reads from the syscolumns table

It looks like this:

Select CONVERT(CHAR(30),sc.name), sc.type, sc.usertype, sc.length, sc.status from syscolumns sc where sc.id = object_id( 'inventory_ext' )

There can be from a few to as many as 20 such statements in a bunch, all using a different table name (with object_id)

Does anyone know if that really is useful ?    Any way to turn that off ?

Thanks
