This dataset focuses the SQL corpus of the [Stack v2 dedup](https://huggingface.co/datasets/bigcode/the-stack-v2-dedup) dataset and provides annotations to each SQL file therein.
[sqlparse](https://github.com/andialbrecht/sqlparse) is used to parse the SQL code, then count keywords and symbols.

Below are the annotation columns.
| **Column Name**                | **Column Description**                               |

| **Keyword.DML**                | Data Manipulation Language commands for modifying database records, e.g. `SELECT`, `INSERT`, `UPDATE`, `DELETE`, `COMMIT`, `MERGE`, `ROLLBACK`. |
| **Keyword.DDL**                | Data Definition Language commands for defining or altering database structure, e.g. `ALTER`, `CREATE`, `DROP`. |
| **Keyword.DCL**                | Data Control Language commands for managing access and permissions, e.g. `GRANT`, `REVOKE`. |
| **Keyword**                    | Reserved words in SQL that represent operations or command, e.g. `FROM`, `WHERE`, `JOIN`, `GROUP`, `ORDER`, `IF`, `WHILE`, `MIN`, `MAX`, `AND`, `OR`, `ON`. |
