You can merge them into one


UPDATE Table
SET col1 = val1,
  col2=  val2,
  col3 = vale,
...
..coln= valn

unless you have different WHERE clauses for each of these UPDATEs.

thanks for answer
but this is not what i want. i have a table formTahavol(v1,v2,v3,....,v77)
now i want to add three columns after v42. so i must add v78,v79,v80 at the end of table, then i have to move data from v43-v77 to v46-v80
