db2

I have a table in db2 which has the following fields

int xyz;
string myId;
string myName;

Example dataset

xyz  |  myid         | myname
--------------------------------
1    |  ABC.123.456  | ABC
2    |  PRQS.12.34   | PQRS
3    |  ZZZ.3.2.2    | blah

I want to extract the rows where myName matches the character upto "." in the myId field. So from the above 3 rows, I want the firs 2 rows since myName is present in myId before "."

How can I do this in the query, can I do some kind of pattern matching inside the query?
