Read and change database records from workflow commands.
Recorded with an earlier Twidget interface. Names, control locations and available options may differ; use the linked documentation for current guidance.
Watch tutorial (4:56)Twidget offers many commands to manage data in your database. Below is a list of the available commands and their functionalities:
Retrieve an entry from a table.
Retrieve multiple entries from a table.
Save an object to a database table.
Save multiple objects to a database table.
Update an entry in a table.
Update multiple entries in a table.
Delete an entry from a table.
Delete multiple entries from a table.
Count records matching your filters without returning the records themselves. Choose a table, add any filters and set a Return as name such as open_orders. The result is a number, including 0 when nothing matches.
In this example, the test uses a sample table containing four matching orders and returns 4.
Check whether at least one record matches. For example, look for a registration with the same event and email before deciding what to do next. The result is true or false.
This test found a matching sample order, so its result is true.
This is useful for decisions, but does not prevent two simultaneous requests creating duplicates. Use a unique index when duplicates must be prevented.
Find a matching record and update it, or add a new record if none exists. Choose a table, define filters that identify the record, and supply the values to save.
For example, match a product by its unique product code and save its latest description and price. Use a unique index on the matching field when it identifies a single record.
This sample matches an order by reference. Supply the values to save below the query.
The test returns the saved order, including its reference and amount.
Change a number field by an amount. An amount of 1 increases it by one; -1 decreases it by one. Choose the matching record, the number field and the amount.
This command is useful for counters and stock changes because it applies the change directly, rather than separately reading a number and saving a replacement. Decide how your workflow should handle missing records and values below zero.
Here, the command finds ORDER-1001, increases its amount by 2, and returns the record After change. Use a negative Change by value to decrease the amount.
Summarise matching records with a count, total, average, lowest or highest value. Optionally choose Group by to produce a summary for each category, customer or other field. See Summarise records.
Use Database Transaction to group supported database commands so their changes succeed together. If the block fails, its changes are rolled back. See Save changes together for limitations and examples.
Read records from a saved external database connection. Select the connection, provide a query, and bind changing values through Parameters. See External database connections.
Use Settings → Database Triggers to run a published event after a live workflow command creates, updates or deletes a record. See Database change triggers for setup, input values and limits.
For examples and setup details, see Summarise Records, Save Changes Together, and External Database Connections.

Send External HTTP Request
Using Twidget, you can send external HTTP requests effortlessly. This functionality allows you to communicate with external servers or APIs. Below, you will find the necessary parameters and structure to set up an HTTP request. Parameters. - URL: The endpoint to which the request will be sent. - Met...
Cache
Cache values let an endpoint, server function or event reuse temporary data. For example, save a product summary for five minutes instead of requesting it from another service every time. A cache is temporary. Keep permanent records in your database and make sure the workflow can obtain the original...
