Switch / Case

Description

The Switch Case transform implements the Switch/Case statement found in popular programming languages like Java.

In our case we route rows of data to one or more target transforms based on the value encountered in a certain field.

Options

Option	Description
Transform name	The name that uniquely identifies the transform.
Field name to switch	The field name that contains the value to use as a bases for the row routing.
Use string contains comparison	If checked, the comparison will be true if the value is found anywhere in the field being tested. Unchecked and the value has to exactly match the field.
Case value data type	The data type of the values specified in this dialog
Case value conversion mask	The conversion mask of the values specified in this dialog (numeric / date values)
Case value decimal symbol	The decimal symbol of the values specified in this dialog (numeric values)
Case value grouping symbol	The grouping symbol of the values specified in this dialog (numeric values)
Case values	Here you can specify a value-target transform pair, one per row. To specify a null value, simply leave the value column blank while entering a target transform. Please note that it is possible to specify the same target transform more than once.
Default target transform	All the rows that don’t match any of the case values above are sent to this target transform.

Description

Transform name

The name that uniquely identifies the transform.

Field name to switch

The field name that contains the value to use as a bases for the row routing.

Use string contains comparison

If checked, the comparison will be true if the value is found anywhere in the field being tested. Unchecked and the value has to exactly match the field.

Case value data type

The data type of the values specified in this dialog

Case value conversion mask

The conversion mask of the values specified in this dialog (numeric / date values)

Case value decimal symbol

The decimal symbol of the values specified in this dialog (numeric values)

Case value grouping symbol

The grouping symbol of the values specified in this dialog (numeric values)

Case values

Here you can specify a value-target transform pair, one per row. To specify a null value, simply leave the value column blank while entering a target transform. Please note that it is possible to specify the same target transform more than once.

Default target transform

All the rows that don’t match any of the case values above are sent to this target transform.

Metadata Injection Support

All fields of this transform support metadata injection. You can use this transform with Metadata Injection to pass metadata to your pipeline at runtime.
