Here is your Query

SQL

SELECT COUNT(T1.Column1) FROM @Table1 T1 INNER JOIN @Table2 T2 ON ( (T1.column1=T2.Column1) AND T1.column2=1)

I have tested this with below sample data

SQL

DECLARE @Table1 AS Table(Column1 INT,Column2 INT)
DECLARE @Table2 AS Table(Column1 INT)

INSERT INTO @Table1 
SELECT 1,1
UNION
SELECT 3,1
UNION
SELECT 2,2

INSERT INTO @Table2 
SELECT 1
UNION
SELECT 2

SELECT COUNT(T1.Column1) FROM @Table1 T1 INNER JOIN @Table2 T2 ON ( (T1.column1=T2.Column1) AND T1.column2=1)

Result of this query according to sample data considered in this example
Count = 1
