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.

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

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;
