MySQL - New/updated row triggers

New/updated row

This trigger picks up rows that are inserted/updated in the selected table or view. Each row is processed as a separate job. It checks for new/updated rows once every poll interval. The poll interval can be 10 mins or 5 mins, depending on your plan. Check the Pricing and Plans page to find out more.

New/updated row trigger New/updated row trigger

Input field Description
Table First, select a table/view to process rows from.
Unique key Next, select a unique key column to uniquely identify rows. This list of columns are generated from the selected table/view.
Sort column Now, select a column to identify updated rows.
WHERE condition Finally, provide an optional WHERE condition to filter rows.

New/updated batch of rows

This trigger picks up rows that are inserted/updated in the selected table or view. These rows are processed as a batch of rows for each job. This batch size can be configured in the trigger input. It checks for new/updated rows once every poll interval. The poll interval can be 10 mins or 5 mins, depending on your plan. Check the Pricing and Plans page to find out more.

Input fields

Table

Select the table/view to process rows from. This can be done either by selecting a table from the pick list, or toggling the input field to text mode and typing the full table name.

Unique key

Values from this selected column is used to deduplicate rows in the selected table.

As such, the values in the selected column should not be repeated in your table. Typically, this column is the primary key of the table (e.g. ID). It should be incremental and sortable. This column can also be indexed for better performance.

Only columns that have PRIMARY KEY or UNIQUE constraints can be used. Run this SQL query to find out which columns fulfill this requirement.

SELECT kcu.column_name
FROM information_schema.key_column_usage kcu, information_schema.table_constraints tc
WHERE
  kcu.constraint_name = tc.constraint_name and
  kcu.table_name = tc.table_name and
  kcu.table_schema = tc.table_schema and
  tc.table_name = "table_name" and
  tc.constraint_type in ("PRIMARY KEY", "UNIQUE")
ORDER BY kcu.column_name

Sort column

Sort column is a column that is updated whenever a row in the table is updated. Typically, this is a timestamp column.

When a row is updated, the Unique key value remains the same. However, it should have it's timestamp updated to reflect the last updated time. Following this logic, Workato keeps track of values in this column together with values in the selected Unique key column. When a change in the Sort column value is observed, an updated row event will be recorded and processed by the trigger.

Only datetime and timestamp column types can be used. Run this SQL query to find out which columns fulfill this requirement.

SHOW COLUMNS FROM invoices WHERE Type in ('datetime','timestamp')

Batch size

Batch size of rows to return in each job. This can be any number between 1 and the maximum batch size. Maximum batch size is 100 and default is 100.

In any given poll, if there are less rows than the configured batch size, this trigger will deliver all rows as a smaller batch.

WHERE condition

This condition is used to filter rows based on one or more column values.

status = 'closed' and priority > 3

Leave blank to process all rows from the selected table.

Complex WHERE conditions with subqueries can also be used. Refer to the WHERE condition guide for more information.
