Data

The Data tool lets you store data directly in MESA. You can trigger workflows when the data is updated and view the data from the Settings page. Additionally, you can seamlessly integrate with business intelligence services for enhanced connectivity.

Configuration

Add a Data Create Record step to your workflow to create a new table. Specify a table name and begin adding columns to your table. Give each column a name and type by choosing one of our supported column types, and select the data to store in that column by selecting variables or adding static text to the column's value field. It is recommended that you label your columns with no spaces included.

Once you save your workflow, to avoid affecting workflows that may use the same table, you can no longer delete the column or adjust your column's Name or Type from the user interface. You can run one of the queries in the Altering Tables section below if you need to adjust your columns.

Browse the Data

Go to the My Account under your account name.

Then, click on the Data tab.

Select View Data to browse the data in the table or Database Options to Query or Alter table:

Example Queries

Only show records that contain a string

SELECT * FROM "customers" WHERE "email" ILIKE '[e-mail]%';

Only show records created after a certain UTC date and time, sorted newest first:

SELECT * FROM "customers" WHERE "mesa_created_at" > '2022-01-04T17:51:00.000Z' 
  ORDER BY "mesa_created_at" DESC;

Join two tables together:

SELECT * FROM "orders" 
  LEFT JOIN "customers" ON "orders"."customer_id" = "customers"."id";

More examples and information about SELECT queries.

Alter Tables

You can remove columns or change their type by running an ALTER query. Go to the Settings Page and click the ⚙ cog icon next to the table. The query box will be pre-populated with some commented-out SQL queries to help you get started.

Remove a column

To remove a column, uncomment the first line and the DROP COLUMN line, replace {{column_name}} to your column and click Run Query. For example:

ALTER TABLE "line_items"
  DROP COLUMN "{{column_name}}"

Change a column type

To change the column type, uncomment the first line and the ALTER COLUMN line corresponding to the column you would like to change by removing the -- at the beginning of each line. Then change the column type to one of the options in the Column types list below:

ALTER TABLE "line_items"
  ALTER COLUMN "order_id" TYPE decimal

Note that in some cases (especially if you have existing data), changing the column may not be as easy as running the query above. In these cases, removing the column and re-adding it from the workflow builder with the new desired column type may be easier.

More examples and information about ALTER queries.

Delete a table

To delete a table, use the following query:

DROP TABLE "Add table name here"

You will need to change the Add table name here text to the name of your table and keep the double quotations.

Column types

Data supports the following column types:

• Text varchar(255): Ideal for most text strings (keys, titles, names, etc). Maximum length: 255 characters.

• Long Text text: For free-form text and JSON blobs.

• Integer int8: For integers and numeric IDs. Supports numbers between -9223372036854775808 and 9223372036854775807.

• Number numeric: For numbers with decimal-point precision.

• Date date: For dates.

• Date and time timestamptz: For date and times. Includes timezone information.

Connect to your data
