I'm trying to lookup a value (c) from a table (Table2) and link it to a value (a) that I have in Table1. When I run the following lines I get an error "Unsupported subquery type cannot be evaluated". I don't know how to resolve it.
SELECT
a,
b,
(SELECT c FROM Table2 AS T2 WHERE T1.a = T2.a) AS c,
FROM Table1 AS T1;
I tried different subquery types but couldn't find the solution.
SELECT T1.a, T1.b, T2.c
FROM Table1 as T1
JOIN Table2 AS T2
ON T1.a = T2.a;
