Quite often it’s the case where certain database tables contain data that rarely, if ever changes. A customer type table would be a good example. This type of data is a candidate for creating a static version.
SQL+ offers two different approaches to building static data. You can generate lists of data, or enumerations.
Static Lists
The table column structure of the query will be represented as properties in a class definition. Each row in the query creates an item in a list of static data, based on the same class definition.
Given the following data in the CustomerType table:
And the following query in the SQL+ Code Generation Utility:
The result would be the following. Comments have been removed for the purpose of this example.

- Name: Alias the column that represents the string constant value as [Name].
- Value: Alias the column that represents the numeric constant value as [Value].
- Comment: Alias the column that represents a comment as [Comment] (optional).
Again with the following data in the CustomerType table:
And the following query in the SQL+ Code Generation Utility:
The result would be the following:
