Lookup alias

A lookup alias consists of a key and a lookup table.

Key

The key is used to find the appropriate alternative in the lookup table. You must use a variable ($variable) as key, for example $countryCode.

Lookup table

The lookup table is a resource that you add to the appropriate resource set. The lookup table contains two columns:

•	The first column contains the key value.

•	The second column contains the alternative associated with the key value.

A connector selection lookup table is shown below:

SWE    spoolSWE

FIN    spoolFIN

Setting a lookup alias

To set a lookup alias for a feature, you select the alias type Lookup and specify a key variable and lookup table. The figure below shows the Connector Selection Method dialog box where you use the key variable $countryCode and lookup table connectors.tbl to select the appropriate output connector.
