+## Summary
+<!--Explain briefly what goes wrong and explain why you believe this is a bug and not the intended behavior of SQLite (if it is not a crash).-->
+We reran the query multiple time, but the output does not change. It is a logic bug because the output is different
+
+## Minimized query
+
+```sql
+CREATE TABLE T (
+  a INTEGER,
+  b TEXT,
+  c REAL
+);
+INSERT INTO T VALUES (substring(-pi(), random() % if(1, NULL, 100)),'' || ('a'),1.25), (2,'b',-3.5), (3,'c',0.0);
+SELECT * FROM T WHERE NOT c < 2.0 ORDER BY c;
+ALTER TABLE T RENAME COLUMN c TO c_r522;
+INSERT INTO T SELECT * FROM T;
+
+SELECT COUNT(*) FROM T;
+```
+
+## Actual output
+
+```sql
+0
+```
+
+## Expectation
+
+```sql
+6
+```
+
+## Flag
+
+```
+
+```
