[unixODBC][Driver Manager]Can't open lib 'SQL Server' : file not found

[unixODBC][Driver Manager]Connnection does not exist ODBC Error in SQLDisconnect Could not open data source.Error in doTryCatch(return(expr), name, parentenv, handler) : Could not open data source.

I have installed MSSQL and unixODBC driver on my linux machine and it is getting refelected in /etc/odbc.ini file too

Can someone please help me in this?

Answer 1

I got the same error when i put below code for connection to MSSQLSERVER

library(RODBC)
dbconnection <- odbcDriverConnect("Driver=SQL Server;Server=192.168.76.60; Database=kaggle;Uid=sa; Pwd=1234")

It throws to me

[unixODBC][Driver Manager]Can't open lib 'SQL Server' : file not found

why this Error thrown? Answer: when we fail to put proper ODBC version name on Driver value.

From where we can get Driver ODBC version name

inside "/etc" folder you will find "odbcinst.ini" file open it and check the version name

[ODBC Driver 17 for SQL Server]
Description=Microsoft ODBC Driver 17 for SQL Server
Driver=/opt/microsoft/msodbcsql17/lib64/libmsodbcsql-17.1.so.0.1
UsageCount=1

so i got ODBC Driver name from here , it will be "ODBC Driver 17 for SQL Server" Then i modify my connection string

library(RODBC)
dbconnection <- odbcDriverConnect("Driver=ODBC Driver 17 for SQL Server;Server=192.168.76.60; Database=kaggle;Uid=sa; Pwd=1234")

And it works fine
