[QGIS-Developer] MSSQL driver not found & Can't open lib 'SQL Server' - QGIS 2.18 LTR on Debian

[kimaidou]

Hi Nyall,

Thanks for your answer. I had already checked that the layers had integer
primary keys. I have discovered that the "wrong" layers had "nvarchar"
fields, instead of "varchar". We changed the types of the view fields from
nvarchar to varchar, and it solved the issue.

Cheers,
Michaël
