SQLGetData Variable-Length in parts no change?

[lpillar]

Based on the documentation here https://docs.microsoft.com/en-us/sql/odbc/reference/syntax/sqlgetdata-function#retrieving-variable-length-data-in-parts, it looks like SQLGetData already supports multiple calls to return variable-length data in parts, but the 4.0 spec appears to propose a new way to fetch variable-length data. Is the 4.0 spec proposing a modification to this behavior, or am I missing something?

If you're talking about section 3.8 (Variable Length Columns), then that's an extension for how to use the existing mechanism to fetch truncated data in parts. Previously there was no way to fetch the data which was truncated while filling a binding.

Ah, that makes sense - thanks!
