Add option to prevent Dynamic Input tool from attempting to connect before macro is run

[cam_w]

I'm adding a 'Dynamic Input' tool to a macro that will dynmaically build the connection string based on User inputs. We intend to distribute this macro as a 'Connector' to our main database system.

However, this tool attempts to connect to the database after 'fake' credentials are supplied in the tool, returning error messages that can't be turned off.

In situations like this, I think you'd want the tool to refrain from attempting connections. Can we add a option to turn off the checking of credentials? I assume that others who are building the connection strings at runtime would also appreciate this as well.

As a corollary, for runtime connection strings, having to define a 'fake' connection in the Dynamic Input tool seems redundant, given we have already set the 'Change Entire File Path' option. There are some settings in the data connection window that are nice to be able to set at design time (e.g. caching, uncommitted read, etc.), but the main point of that window to provide the connection string is redundant given that we intend to replace it with the correct string at runtime. Could we make the data connection string optional?

To combine the above points, perhaps if the connection string is left blank, the tool does not attempt to connect to the connection string at runtime.
