As was mentioned in a comment, Erland Sommarskog wrote a series of articles on this topic (linked-to below). The articles are very thorough and can serve as reference material. While they are specific to SQL Server (T-SQL), some of the techniques mentioned might also work for other RDBMS (such as using an XML data type):

• Arrays and Lists in SQL Server 2008 Using Table-Valued Parameters:

  • Table-Valued Parameters (TVPs)

• Arrays and Lists in SQL Server 2005 and Beyond When TVPs Do Not Cut it:

  • string serialization and de-serialization of scalar values
  • SQLCLR
  • passing structured list data via the XML data type
  • Dynamic SQL

• Arrays and Lists in SQL Server 2000 and Earlier
