who

List variables that are in connected data source

Since R2024a

Syntax

list = who(connectionObj)

Description

list = who(connectionObj) returns a list of the variables that are in the connected data source.

If the data connection can see multiple definitions of the same variable (for example, in a data dictionary and in a referenced dictionary), the function lists each instance of the variable.
