+## Minimized query
+
+```sql
+BEGIN DEFERRED;
+PRAGMA journal_mode;
+PRAGMA cell_size_check = TRUE;
+PRAGMA cache_spill = OFF;
+.dbconfig fk on
+CREATE TABLE T1 (
+  a INTEGER,
+  b TEXT
+);
+CREATE TABLE T2 (
+  a INTEGER,
+  b TEXT
+);
+INSERT INTO T1 VALUES (1,'a'),(2,'b');
+INSERT INTO T2 VALUES (1,'c'),(1,'d');
+SELECT T1.b,
+(
+  SELECT GROUP_CONCAT(b,',')
+  FROM T2
+  WHERE T2.a=T1.a
+) AS c
+FROM T1;
+WITH n AS NOT MATERIALIZED (SELECT b FROM T1) SELECT * FROM n;
