I am not sure why the nightly build fails, but not the other. Adding NetworkOptions.jl didnt help.. below is the extracted part form the Oracle toml. I dont see network options there so I am not sure how to make it pass the nightly build before merging.

[deps]
Dates = "ade2ca70-3891-5945-98fb-dc099432e06a"
Libdl = "8f399da3-3557-5675-b5ff-fb832c97cbdb"
Tables = "bd369af6-aec1-5ad0-b16a-f7cc5008161c"

[compat]
Tables = "1"
julia = "1.6"

[extras]
DataFrames = "a93c6f00-e57d-5684-b7b6-d8193f3e46c0"
Test = "8dfed614-e22c-5e08-85e1-65c5234f0b40"

[targets]
test = ["Test", "DataFrames"]

and downloads does have NetworkOptions in its dependencies.

the new error is as follows. I have no idea why, so I think oracle support will have to live here in this branch

ERROR: LoadError: ArgumentError: Package LibGit2 does not have LibGit2_jll in its dependencies:
- Note that the following manifests in the load path were resolved with a different
  julia version, which may be the cause of the error:
    /home/runner/work/TidierDB.jl/TidierDB.jl/Manifest.toml (v1.9.1)```

I am going to close this and use ODBC.jl. I think I will leave the branch available for the time being to any user would prefer to connect with Oracle.jl.
