### Install pyodbc using pip

Source: https://github.com/mkleehammer/pyodbc/blob/master/README.md

The recommended method for installing pyodbc is using pip. Ensure you have Python and pip installed.

```bash
python -m pip install pyodbc
```

--------------------------------

### Install unixODBC on macOS

Source: https://github.com/mkleehammer/pyodbc/blob/master/README.md

On macOS, install unixODBC using Homebrew before installing pyodbc if you don't have an ODBC driver manager.

```bash
brew install unixodbc
python -m pip install pyodbc
```

--------------------------------

### Build pyodbc Extension In-Place

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Builds the C++ extension for pyodbc in the current directory. This is useful for a fast development loop before installing.

```sh
python setup.py build_ext --inplace
```

--------------------------------

### Run Full pyodbc Test Matrix with Tox

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Executes the complete pyodbc test suite across multiple Python interpreters using tox. Ensure tox is installed via pipx.

```sh
tox
```

--------------------------------

### Build and Test pyodbc In-Place

Source: https://github.com/mkleehammer/pyodbc/blob/master/HACKING.md

Build the library in-place for rapid development testing. Run pytest from the root directory to use the newly built library.

```bash
python setup.py build_ext --inplace
pytest test/test_postgresql.py -vxk test_text
```

--------------------------------

### Build and Test pyodbc with Trace Output

Source: https://github.com/mkleehammer/pyodbc/blob/master/HACKING.md

Build the library with PYODBC_TRACE enabled and run tests with the -s flag to capture output when segmentation faults occur.

```bash
python setup.py build_ext --inplace -D PYODBC_TRACE
pytest test/test_postgresql.py -vxk test_text -vs
```

--------------------------------

### Build pyodbc with Tracing Enabled

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Builds the pyodbc C++ extension with tracing enabled using the PYODBC_TRACE flag. This is helpful for debugging crashes.

```sh
python setup.py build_ext --inplace -D PYODBC_TRACE
```

--------------------------------

### Run pyodbc Tests for a Specific Interpreter with Tox

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Runs the pyodbc test suite for a single specified Python interpreter (e.g., py312) using tox.

```sh
tox -e py312
```

--------------------------------

### Run Specific pyodbc Tests

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Executes a specific test case for pyodbc using pytest. The `-vxk` flags enable verbose output, show captured stdout, and filter tests by name substring.

```sh
pytest tests/sqlite_test.py -vxk test_text
```

--------------------------------

### Debug pyodbc Crashes with Tracing

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Runs pyodbc tests with tracing enabled and pytest's `-s` flag to capture output during segfaults. This aids in debugging crashes.

```sh
pytest tests/sqlite_test.py -vxs -k test_text
```

--------------------------------

### Pass Pytest Arguments via Tox

Source: https://github.com/mkleehammer/pyodbc/blob/master/CLAUDE.md

Executes pyodbc tests using tox for a specific interpreter while passing additional arguments to pytest. The `--` separates tox arguments from pytest arguments.

```sh
tox -e py312 -- -rA
```
