## Minimized query
|
|
|
|
```sql
|
|
SAVEPOINT sp8595;
|
|
SAVEPOINT sp6434;
|
|
CREATE TABLE T (
|
|
a TEXT,
|
|
b TEXT
|
|
);
|
|
INSERT INTO T VALUES ('a','b'), ('c','d');
|
|
SELECT * FROM T WHERE a <= REPLACE('a;',';','') AND b = 'b';
|
|
SELECT GROUP_CONCAT(b, '|') FROM T;
|
|
ROLLBACK TRANSACTION TO SAVEPOINT sp6434;
|
|
RELEASE SAVEPOINT sp6434;
|
|
ROLLBACK TRANSACTION TO SAVEPOINT sp8595;
|
