Implementation Reference
- src/tools/table-tools.js:15-48 (handler)The main handler function for the 'hana_list_tables' tool. It handles optional schema_name (defaults from config), validates it, queries tables using QueryExecutor.getTables, formats the result, and returns a formatted response or error.
static async listTables(args) { logger.tool('hana_list_tables', args); let { schema_name } = args || {}; // Use default schema if not provided if (!schema_name) { if (config.hasDefaultSchema()) { schema_name = config.getDefaultSchema(); logger.info(`Using default schema: ${schema_name}`); } else { return Formatters.createErrorResponse( 'Schema name is required', 'Please provide schema_name parameter or set HANA_SCHEMA environment variable' ); } } // Validate schema name const schemaValidation = Validators.validateSchemaName(schema_name); if (!schemaValidation.valid) { return Formatters.createErrorResponse('Invalid schema name', schemaValidation.error); } try { const tables = await QueryExecutor.getTables(schema_name); const formattedTables = Formatters.formatTableList(tables, schema_name); return Formatters.createResponse(formattedTables); } catch (error) { logger.error('Error listing tables:', error.message); return Formatters.createErrorResponse('Error listing tables', error.message); } } - The input schema definition for the 'hana_list_tables' tool, defining schema_name as an optional string parameter.
