Using varchar record in SELECT query

Question

Hi, from a VARCHAR field I get the string ",1,2,3,4,5,6,".
I wish to use it in a SELECT query like:
SELECT * FROM TABLE WHERE ID IN (1,2,3,4,5,6)
Is there a way to obtain this in a tsql query ?
Thank you
Stefano

CREATE TABLE t1
 col1 INT NOT NULL PRIMARY KEY,
 col2 VARCHAR(50) NOT NULL
INSERT INTO t1 VALUES (1,'10,11,12')
INSERT INTO t1 VALUES (2,'13')
INSERT INTO t1 VALUES (3,'14,15')
CREATE TABLE t2
 col1 INT NOT NULL PRIMARY KEY,
 col2 VARCHAR(50) NOT NULL
INSERT INTO t2 VALUES (10,'A')
INSERT INTO t2 VALUES (11,'B')
INSERT INTO t2 VALUES (12,'C')
INSERT INTO t2 VALUES (13,'D')
INSERT INTO t2 VALUES (14,'E')
INSERT INTO t2 VALUES (15,'F')
SELECT DISTINCT O.col1, O.col2
FROM t1 T
   INNER JOIN t2 O
      ON (PATINDEX('%,' + CAST(O.col1 AS varchar(10)) + ',%',
