Question

i’m not sure how to ask this question or what is the right “keyword” for it to search/google.
what i have here is

=========================
=   ID   =   Running#   =
=========================
=   A    =      3       =
=   A    =      4       =
=   A    =      5       =
=   E    =      6       =
=   E    =      3       =
=   G    =      4       =
=   G    =      7       =
=   T    =      3       =
=========================

What i wish to get the return like
A,E,T in one string, where they having running# of 3

You need to use GROUP_CONCAT for this,

SELECT GROUP_CONCAT(ID)
FROM tablename
Where Running = 3
