 - If you have foreign key relationships between tables, ensure you are importing the tables in the right order. You cannot refer to a table that does not yet exist.
 - If you receive a `"cannot start a transaction within a transaction"` error, make sure you have removed `BEGIN TRANSACTION` and `COMMIT` from your dumped SQL statements.
 
+### Resolve `Statement too long` error
+
+If you encounter a `Statement too long` error when trying to import a large SQL file into D1, it means that one of the SQL statements in your file exceeds the maximum allowed length. To resolve this issue, try one of the following approaches:
+
+- Convert a single large `INSERT` statement into multiple smaller `INSERT` statements. For example:
+
+```sql
+INSERT INTO users (id, full_name, created_on)
+VALUES
+  ('01GREFXCN9519NRVXWTPG0V0BF', 'Catlaina Harbar', '2022-08-20 05:39:52'),
+  ('01GREFXCNBYBGX2GC6ZGY9FMP4', 'Hube Bilverstone', '2022-12-15 21:56:13'),
+  ...
+  ('01GREFXCNF67KV7FPPSEJVJMEW', 'Riane Zamora', '2022-12-24 06:49:04');
+```
+
+- Break it into multiple `INSERT` statements:
+
+```sql
+INSERT INTO users (id, full_name, created_on)
+VALUES
+('01GREFXCN9519NRVXWTPG0V0BF', 'Catlaina Harbar', '2022-08-20 05:39:52');
+INSERT INTO users (id, full_name, created_on)
+VALUES
+('01GREFXCNBYBGX2GC6ZGY9FMP4', 'Hube Bilverstone', '2022-12-15 21:56:13');
+```
+
+- If you have a single large `INSERT` statement with many rows, break it into smaller chunks. For example, instead of inserting 1,000 rows in one statement, try splitting that into 250 rows.
