Solving a Collation Problem between Two Tables

this will help I have the following SQL script, trying to perform a union on two tables located on the same database. One table appears to have a different collation type , You have to change the collation of each column individually e.g.
select OtherCols, Col1, Col6, Col7
from ns.TurnsCOS 
union all 
select OtherCols, Col1 collate SQL_Latin1_General_CP1_CI_AS, Col6 collate SQL_Latin1_General_CP1_CI_AS, Col7 collate SQL_Latin1_General_CP1_CI_AS
from ns.TurnsValue 
ALTER TABLE [TableName] ALTER COLUMN [Col_Name] 
            [Existing Data-Type] COLLATE [New_Collation] [NULL | NOT NULL];  
GO

around this issue Database collation is just the default setting for new columns.
To change the collation of an existing column, you'd have to alter table. For example:
alter table YourTable alter column col1 varchar(10) collate Arabic_CI_AI

I wish did fix the issue. You will have to specify according to which collation you wish to do the join (or where clause)
See the example below on how to code this.
create table x( id int, name varchar(256) collate SQL_SwedishStd_Pref_CP1_CI_AS)
create table y( id int, name varchar(256) collate SQL_Latin1_General_CP1_CI_AS)

insert into x values (1, 'Filip')
insert into y values (1, 'Filip')
select * 
  from x
  join y 
    on x.name collate SQL_Latin1_General_CP1_CI_AS = y.name 
select * 
  from x
  join y 
    on x.name = y.name collate SQL_SwedishStd_Pref_CP1_CI_AS 
alter table x alter column name varchar(256) collate SQL_Latin1_General_CP1_CI_AS
select * 
  from x
  join y 
    on x.name = y.name

like below fixes the issue There is a linear time algorithm for this. This algorithm is well explained by orezvani in this post on Computer Science section of stackexchange. I translated the orezvani pseudo code in R:
max_subset<-function(S,K){
  R <- S %% K
  Res <- c()
  for(k in 1:(ceiling(K/2)-1)){
    index_k = which(R==k)
    index_K_k = which(R==(K-k))
    if(length(index_k) >= length(index_K_k)){
      Res <- c(Res, S[index_k])
    }else{
      Res <- c(Res, S[index_K_k])
    }
  }
  print(R)
  Res <- c(Res, S[which(R==0)][1])
  if(K %% 2 == 0){
    Res <- c(Res, S[which(R==(K/2))][1])
  }
  return(Res)
}
