Обсуждение: How would I store little key-Nr to text lists?
Hi how would I store little key-Nr to text lists? Like e.g. colors 1 red 2 green 3 blue Maybe I later also need to add 4 yellow? Obviously the numbers are used for foreign keys in data tables and the texts appear in selects. On the other hand users should chose from listboxes in an application so I need to be able to read the (key, ext) tupels. For now I use 2 column tables that in selects get joined to a data table. Is there a more clever way ?
