Oracle - Select actions

Select rows

This action lets you select rows based on certain criteria defined by a WHERE condition. Rows from the selected table that match the WHERE condition are returned as the output of this action.

Select rows action

Table/Views

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

WHERE condition

Provide a WHERE condition to filter rows. This condition can be as simple as filtering a single record by its ID.

CUSTOMER_ID = 123

Alternatively, it can be used to select multiple rows based on values in one or more columns.

CUSTOMER_EMAIL = '[email protected]' AND PRIORITY = 1

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

Parameters

Used in conjunction with your WHERE condition to prevent SQL injection. After declaring named bind variables in your WHERE input, assign values to these variables using this input field. Learn more

Order by

Rows returned from this action can be ordered based on the Order by input field. This field is used to change the default ordering of rows from your Oracle database.

You can also define the direction of order for each column you wish to order by. The following order by statement orders rows by priority in ascending order followed by created_date in descending order (latest first).

CUSTOMER_ID DESC

Limit

This input field determines the maximum number of rows to return. The default limit is 100 and capped at a maximum of 1000 rows for a single Select rows action.

Offset

This input field gives you the option to fetch only a page of results from the entire results set. For example, to skip the first 100 rows of the selected results set, input 100 to this field. The default is 0.

Select rows using custom SQL

This action lets you select rows based on a custom SQL query. Rows that are returned from the query are returned as the output of this action.

SQL

Provide the SQL query to be executed to select rows. This query is used to generate the output datatree. To do this, the SQL executes once when you provide it. You can map datapills here to execute dynamically changing SQL statements. Remember to wrap datapills in quotes (''). Do not add a ; at the end of your SQL query as this causes the action to fail.

Avoid using limit clauses like ROWNUM in your SQL. This is because the limit to the number of rows returned in the query is based on the value defined in the Limit input field. Adding your own limit clause causes the action to fail.

Limit

This input field determines the maximum number of rows to return. The default limit is 100 and capped at a maximum of 1000 rows for a single Select rows using custom SQL action.

If this field is left blank, ROWNUM <= 100 is used.
