Get primary keys of an Access database
« on: February 13, 2024, 12:25:20 pm »
Hello,

I am connecting to an Access database (.accdb file) using ODBC.
I want to know what the primary key of a table is, but I can't find how to do it.
It seems that SQLPrimaryKeys is not supported by MS-Access ODBC drivers and then UpdateIndexDefs is not working.
Does anyone know how to get the primary key?

Thank you

Have you analyzed the FieldDefs?

That said:
AFAIK, Not possible with MS Access, since MS Access stores a Table's metadata in a binary blob inside a sys-table called "MSysObjects"
