• Password: The password of TiDB Cloud cluster.
• User: The username of your TiDB Cloud cluster.
• Database: The database name.
• Table: The table name. You can use From list mode to choose one or Name mode to type table manually.
• Update Key: The name of the item's property which decides which rows in the database should be updated. Item is the data sent from one node to another. A node performs its action on each item of incoming data. For more information about item in n8n, see n8n documentation.

Limitations

1. Normally only one SQL statement is allowed in the Execute SQL operation. If you want to execute more than one statement in a single operation, you need to manually enable tidb_multi_statement_mode.
2. The Delete and Update operation need to specify one field as a key. For example, the Delete Key is set to id, which is equivalent to executing delete from table where id = ${item.id}. Currently, it only supports specifying one key.
3. The Insert and Update operation need to specify the comma-separated list in the Columns field, and the field name must be the same as the input item's property.
