Insert (result output)
This operation outputs the operation results from insertion to a database.
The result of what is written to the database is output to "metadata\succeeded" of the output schema.
When the input data is successfully written to the database, "true" is output.
When the input data is not successfully written to the database, "false" is output.
The "true" or "false" value that is output to "metadata\succeeded" of the output schema is a character string.
If you want to handle the output value as a boolean value, use the following logic to compare values, and then use the value of the comparison results:
-
Condition > Boolean > Boolean Constant
-
Condition > String > Equal
You can display the insert (result output) operation screen by displaying the script canvas on the Designer screen, clicking the following items in the following order, and then dragging and dropping the component icon onto the script canvas:
-
Tool palette > Database > SQL Server > Insert(result output)
