A Node-RED node to execute queries and stored procedures in Microsoft SQL Server and Azure Databases SQL2000 ~ SQL2019.

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.

Screen shot


Features include...

  • Connect to multiple SQL Servers and Azure databases from SQL2000 ~ 2019
  • Perform multiple queries in one go & get back multiple recordsets (depends on the queries sent)
  • Supports stored procedure execute
  • Use env vars in the config node for all fields (including credentials). e.g...
    • Server {{{SQL_IP}}}
    • Password {{{SQL_PW}}}
  • Use mustache in your SQL queries including msg, flow and global context. e.g...
    • SELECT TOP {{{payload.maxRows}}} * FROM [MyTable] WHERE Name = '{{{flow.name}}}' AND quantity <= {{{global.maxQty}}}
    • View the final query (mustache rendered into values) in msg.query to understanding what happened to your {{{mustache}}} parameters
  • Enter parameters in the UI or send parameters in via msg, flow or global variables for use in your SQL queries e.g...
    • SELECT * FROM [MyTable] WHERE Name = @name AND quantity <= @maxQty
    • View the final parameters (rendered with final values) in msg.queryParams that were used in the query to aid debugging
    • View output parameters values in msg.queryParams after the query has executed
  • Choose between throwing an error to the catch node or outputting an error property in msg.error
  • Additional properties are in the msg object (use a debug node with "complete msg object" set to see whats available)



Use the Manage Palette > Install option from the menu inside node-red


Alternatively in your Node-RED user directory, typically ~/.node-red, run

npm install node-red-contrib-mssql-plus


Please refer to the built in help in the info panel in node red.

Sample flow

Demonstrating mustache rendering, input parameters, mutliple queries, print info...

  • Payload: {"count": 5, "age": 35}
  • Parameters
    • name, varchar(20), stephen
    • age, int, msg.payload.age
  • Query:
      PRINT @name
      SELECT TOP {{{payload.count}}} * 
      FROM testdb.dbo.[MyTable] WHERE Name = @name
      SELECT TOP {{{payload.count}}} * 
      FROM testdb.dbo.[MyTable] WHERE Age = @age
      PRINT 'complete'
  • After Rendering Mustache:
      PRINT @name
      SELECT TOP 5 * 
      FROM testdb.dbo.[MyTable] WHERE Name = @name
      SELECT TOP 5 * 
      FROM testdb.dbo.[MyTable] WHERE Age = @age
      PRINT 'complete'
