A Node-RED node to execute queries, stored procedures and bulk inserts in Microsoft SQL Server and Azure Databases SQL2000 ~ SQL2022.
Importantly, this package comes with pre-built linux drivers for communicating with the Azure & MS SQL services (using TDS protocol), removing the need to set-up environment level MSSQL (or similar) drivers.
