None of the table name falls under more than one schema

In my database there are more than 10 schemas. How to ensure that none of the table  is not fall under more than one schema.

I mean that if a table name say for example tEmployee if falling under the schema [dbo] and [MyDB.Employee] means that should be shown in result.

How to write TSQL to achieve that? Please do assist.

I think this one may boil down to personal preference, but here's a different method with joins/grouping:

select
	T1.name as tableName,
	schema_name( T1.schema_id ) as schemaName
from
	sys.tables as T1
		inner join sys.tables as T2 on T1.name = T2.name and T1.schema_id <> T2.schema_id
group by
	T1.name,
	T1.schema_id
order by
	tableName,
	schemaName;

Give this a whirl....

SELECT
TABLE_SCHEMA,
TABLE_NAME,
row_number() over (partition by TABLE_NAME order by Table_Name)
FROM INFORMATION_SCHEMA.TABLES
Order by Table_Name


;With CTE As (
SELECT top 100
TABLE_SCHEMA,
TABLE_NAME,
row_number() over (partition by TABLE_NAME order by Table_Name) As NUMBER
FROM INFORMATION_SCHEMA.TABLES
Order by Table_Name
)
Select * from CTE
where NUMBER > 1

This might work better

;With CTE As (
SELECT top 100
TABLE_SCHEMA,
TABLE_NAME,
row_number() over (partition by TABLE_NAME order by Table_Name) As NUMBER
FROM INFORMATION_SCHEMA.TABLES
Order by Table_Name
)
Select distinct
IST.* 
from CTE C
Inner Join  INFORMATION_SCHEMA.TABLES IST on C.TABLE_NAME = IST.TABLE_NAME
where NUMBER > 1
