Implement the Go ADBC Interface and build script #865
Conversation
* **ADBC Interface** - Implement the Go ADBC Interface in `adbc_driver.go` - Adhere to the ADBC specifications * **Build Script** - Add `build.sh` to compile the Go ADBC Interface as a C shared object - Use the existing SDK for compilation

this file seems wrong? there's nothing here and it's using the wrong library version
| #include <adbc.h> | ||
| #include <adbc_driver_manager.h> |

include paths should be <arrow-adbc/adbc.h> and <arrow-adbc/adbc_driver_manager.h>

Where is this function defined? There is no AdbcDriverManagerInitialize() in adbc_driver_manager.h`
| // Initialize the ADBC driver manager | ||
| AdbcStatusCode status = AdbcDriverManagerInitialize(); | ||
| if (status != ADBC_STATUS_OK) { | ||
| std::cerr << "Failed to initialize ADBC driver manager: " << AdbcStatusCodeToString(status) << std::endl; |

AdbcStatusCodeMessage not AdbcStatusCodeToString

| // Register the Arrow Flight SQL driver | ||

this function doesn't exist either, did you mean AdbcLoadDriver?
Also, if you are only using the flightsql driver, why use the driver manager? Why not just link against libadbc_driver_flightsql.so directly?

AdbcConnectionNew and AdbcConnectionInit?

You should return an std::shared_ptr<arrow::RecordBatchReader> to stream the results instead
| AdbcResult result; | ||
| status = AdbcStatementExecuteQuery(&statement, &result); | ||
| if (status != ADBC_STATUS_OK) { | ||

| arrow::Status arrow_status = arrow::flight::sql::ResultToTable(result, &table); | ||

execute query uses an ArrowArrayStream there is no AdbcResult
