After Connecting, you can execute a SQL statement and retrieve the results.

SELECT Procedure

You can execute queries using odbc_exec. This will return a resource that you can use to read results.

$stmt = odbc_exec($cnx, "SELECT actor.attributes.email, repository.name FROM [publicdata].[samples].github_nested WHERE repository.name = 'EntityFramework'");

Iterating over the Results

You can use odbc_fetch_array to fetch the next row as an array.

while ($row = odbc_fetch_array($stmt)) {
    echo "actor.attributes.email = ", $row["actor.attributes.email"], "\n";
    echo "repository.name = ", $row["repository.name"], "\n";
}
