try to create stored procedure,
1. first you need to search tables in the databases with matching name,for example

SQL

sp_MSforeachdb 'SELECT "?" AS DB, * FROM [?].sys.tables WHERE name like ''Students'''

find you the databases where Students contains. refer Find a Table on a SQL Server across all Databases[^]

2. Now you need to build union sql statement based on above database and table values in your stored procedure. for example if you have BR_1, BR_2, your sql string will be

SQL

SELECT * FROM BR_1.dbo.Students
union
SELECT * FROM BR_2.dbo.Students

3. finally execute the dynamically created sql statement and fetch the data
