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.

Note

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 > PostgreSQL > Insert(result output)

Stream setting

Relation-to-Stream Operator

Method for stream operation

The stream operation converts the results data of relational operations into stream data.

Data such as all data (RSTREAM) or added data (ISTREAM) is output as stream data according to changes in the output relation (*1).

Select from the following methods for stream operation:

  • RSTREAM

    All data is processed.

  • ISTREAM

    Only data that differs from the directly preceding data is processed.

If you omit this setting, "RSTREAM" is used to perform the operation for the relation.

Window type

Processing unit for stream operation

Select from the following units for processing with the stream operation:

  • TUPLES

    Use tuples (*2) for processing.

  • SECONDS

    Use seconds for processing.

  • MILLISECONDS

    Use milliseconds for processing.

If you omit this setting, "TUPLES" is selected.

Window

Execution count for stream operation

Specify a number from "1" through "2147483646" for the execution count for the stream operation.

If you omit this setting, "1" is selected.

*1

:

The operation is executed during conversion processing, and the data that will become the result is extracted as a relation.

This relation is called output relation.

*2

:

A tuple represents a stream component. A tuple is used as the unit for data that moves the stream.
