Update Character Sets and Collations

The character set or collation for the Spider Table can be updated or modified using the ALTER TABLE statement.

On the Spider Node, alter the Spider Table's character set and collation:

ALTER TABLE spider_hq_sales.invoices
   DEFAULT CHARACTER SET 'utf8mb4'
   DEFAULT COLLATE 'utf8mb4_general_ci';

If the new character set and collation are not compatible with the character set and collation used by the Data Table, you must also alter the character set and collation for the Data Table on the Data Node.

Update Connection Options

On the Spider Node, alter the table's connection details:
