This post show how work creating and inserting, selecting data from tables with the same name of table but with diffrent size of letters in this name.
Begin with set collation to your database.
ALTER DATABASE mydb COLLATE Polish_CI_AI;
This database is insensitive, so two diffrent size of letter will be as the same(example a=A).
Now create table of t name.
create table t (id int);
create table T (id int);
insert into T values(3);
select id from t;
select id from T;
