 By default `timeTravelQuery()` uses `follower_read_timestamp()` function if no arguments passed.
 For another supported timestamp arguments and additional information please refer to

+You can get the generated SQL from the query builder by calling `getQuery()` or `getQueryAndParameters()`.
+
+If you just want the query you can use `getQuery()`
+
+```typescript
+const sql = await dataSource
+    .getRepository(User)
+    .createQueryBuilder("user")
+    .where("user.id = :id", { id: 1 })
+    .getQuery()
+```
+
+Which results in:
+
+```sql
+SELECT `user`.`id` as `userId`, `user`.`firstName` as `userFirstName`, `user`.`lastName` as `userLastName` FROM `users` `user` WHERE `user`.`id` = ?
+```
+
+Or if you want the query and the parameters you can get an array back using `getQueryAndParameters()`
+
+```typescript
+const queryAndParams = await dataSource
+    .getRepository(User)
+    .createQueryBuilder("user")
+    .where("user.id = :id", { id: 1 })
+    .getQueryAndParameters()
+```
+
+Which results in:
+
+```typescript
+[
+ "SELECT `user`.`id` as `userId`, `user`.`firstName` as `userFirstName`, `user`.`lastName` as `userLastName` FROM `users` `user` WHERE `user`.`id` = ?",
+ [ 1 ]
+]
+```
