package groovy.sql;
This class defines a wrapper for accessing a specific column in ResultSetMetaData. This allows iteration over columns using idiomatic Groovy, e.g.:
 meta.each {col ->
   println col.columnName
 }
 
All ResultSetMetaData column methods taking a column index are available on a column either as a no-arg getter or via a property.

This wrapper is created by an iterator invoked for ResultSetMetaData.
