That node is over 7 years old, uses old libraries (with CVE issues) and has a number of known bugs and last, but not least, does not have the additional features that make mssql-plus the best SQL node in the catalog.
I suggest you remove that and add the newer/better one and use parameters.
You have 2 choices to acheive that ^
- remove all traces of mssql from your flows
- remove node-red-contrib-mssql via palette manager
- install node-red-contrib-mssql-plus via palette manager
- restart node-red
- add the SQL nodes back into your flows
OR
- stop node-red
- run
npm remove node-red-contrib-mssql
(in a terminal, in ~/.node-red) - run
npm install node-red-contrib-mssql-plus
(in a terminal, in ~/.node-red) - start node-red
The 2nd version is my recommendation but not everyone is comfortable with command line.
