I am trying to connect to our Databricks SQL endpoint using PHP in a Docker container.
I setup my Docker container to download and configure the ODBC driver as specified here: https://docs.databricks.com/integrations/bi/jdbc-odbc-bi.html#install-and-configure-the-odbc-driver-for-linux
My Docker setup is at https://github.com/rlorenzo/databricks_php
However, when it try to connect using ODBC from my PHP test script I get the error:
Warning: odbc_connect(): SQL error: [unixODBC][FreeTDS][SQL Server]Unable to connect to data source, SQL state S1000 in SQLConnect in /test_connection.php on line 14
ODBC connect failed: S1000
When I try to connect using the PDO library I get a different error message:
SQLSTATE[08S01] SQLConnect: 20009 [unixODBC][FreeTDS][SQL Server]Unable to connect: Adaptive Server is unavailable or does not exist
The connection details are correct because I was able to connect to the Databricks SQL endpoint using Datagrip. I can also verify that the ODBC library is properly installed because I can query a Microsoft SQL Server.
I must have the Databricks ODBC Connector misconfigured somehow, but I am clueless. From my view everything matches the documentation.
I have tried contacting Databricks support, but they have been unhelpful so far.
The problem was that the Databricks SQL driver does not yet support ARM, which my laptop and Docker container was building for. See ('01000', "[01000] [unixODBC][Driver Manager]Can't open lib '/opt/simba/spark/lib/64/libsparkodbc_sb64.so' : file not found (0) (SQLDriverConnect)")
I updated my repo at https://github.com/rlorenzo/databricks_php with a working example and forced the container to build an x86 version.
Will update my repo if Databricks ever supports ARM.
Hope this helps someone in the future.
