Interact with your tables and data inside CARTO, as if you were running SQL statements.

This component is still under support but it will not be further developed. We don’t recommend starting new projects with it as it will eventually become deprecated. Instead, learn more about our new APIs here

Creating Tables with the SQL API

Writing data to your CARTO account enables you to manage data through SQL queries, it does not automatically connect tables as datasets to Your datasets dashboard in CARTO.

You must apply the CDB_CartodbfyTablefunction to a target table in order to create and display connected datasets in your account. This additional step of “CARTOfying” data is the process of converting an arbitrary PostgreSQL table into a valid CARTO table, and registering it into the system so that it can be used in the graphical user interface, and the CARTO Engine, to generate maps and analysis.

Create Tables

To create a visible table in CARTO, run the following SQL query with the SQL API:

1
2
3
4
5
6
7
CREATE TABLE {table_name}
 (
 {column1} {data type},
 {column2} {data type},
 {column3} {data type},
 ...
 );

While this begins the process of creating the structure for the table, it is still not visible in your dashboard. Run the following request to make the table visible.

1
SELECT cdb_cartodbfytable({table_name});

Tip: If you belong to an organization, you must also include the username as part of the request.

1
SELECT cdb_cartodbfytable({username}, {table_name});

You will get an Please set user quota before cartodbfying tables error if you don’t include the username as part of the request.

The table is created and added as a connected dataset in Your datasets dashboard. Refresh your browser to ensure that you can visualize it in your account. Once a table is connected to Your datasets dashboard in CARTO, any modifications that you apply to your data through the SQL API are automatically updated.

Rename Tables

To rename a connected dataset in Your datasets dashboard, run the following SQL query with the SQL API:

1
ALTER TABLE {table_name} RENAME to {renamed table_name};

It may take a few seconds for the connected table to appear renamed. Refresh your browser to ensure that you can visualize the changes in Your datasets dashboard.

Remove a Table

If you remove a table, any maps using the connected dataset will be affected. The deleted dataset cannot be recovered. Even if you create a new table with the same name as a removed table, CARTO still internalizes it as a different table.

Some users and third-party libraries update the data from a map dataset making a DROP TABLE + CREATE TABLE + INSERT in the table. Doing that, your map will be affected unless you make the DROP TABLE + CREATE TABLE inside a transaction. But our recommendation is to use TRUNCATE TABLE + INSERT.

To remove a connected dataset from Your datasets dashboard, run the following SQL query with the SQL API:

1
DROP TABLE {table_name};

This removes the connected table from Your datasets dashboard. Refresh your browser to ensure that the connected dataset was removed.
