Answer 1

If your table has 23 columns and you dont want to insert into all 23 columns then mention the required column list in Insert. No need to add commas

Insert into tbl_tarifmoshtari 
(p1,p2,p3,p4,p5,p6,p7,p8,p9,p10,p11,p12,p13,p14,p15,p16)
values
(@p1,@p2,@p3,@p4,@p5,@p6,@p7,@p8,@p9,@p10,@p11,@p12,@p13,@p14,@p15,@p16)
