Good afternoon, my company has an interest in buying InDesign, however before we do so I need to make sure that I can link a SQL Database to InDesign. As well as know if there are any limitations to linking an SQL Database to InDesign. Any help would be greatly appreciated.
You'd need to give us a lot more information before we could actually make suggestions. This is not a feature that's really built into InDesign; most of the database-driven publishing workflows I've touched would run SQL -> XML -> ID or SQL -> CSV -> ID. A third way would be SQL -> InCatalog or InData -> ID. Those last two are third-party special-use plugins. There are quite a few such plugins.
So: your question is kind of vague and surface-level, and so I'd offer the clear, surface-level answer of "no." But it's Deeper Than It Looks.
