# pgconn
|
|
|
|
Package pgconn is a low-level PostgreSQL database driver. It operates at nearly the same level as the C library libpq.
|
|
It is primarily intended to serve as the foundation for higher level libraries such as https://github.com/jackc/pgx.
|
|
Applications should handle normal queries with a higher level library and only use pgconn directly when required for
|
|
low-level access to PostgreSQL functionality.
|
|
|
|
## Example Usage
|
|
|
|
```go
|
|
pgConn, err := pgconn.Connect(context.Background(), os.Getenv("DATABASE_URL"))
|
|
if err != nil {
|
|
log.Fatalln("pgconn failed to connect:", err)
|
|
}
|
|
defer pgConn.Close(context.Background())
|
|
|
|
result := pgConn.ExecParams(context.Background(), "SELECT email FROM users WHERE id=$1", [][]byte{[]byte("123")}, nil, nil, nil)
|
|
for result.NextRow() {
|
|
fmt.Println("User 123 has email:", string(result.Values()[0]))
|
|
}
|
|
_, err = result.Close()
|
|
if err != nil {
|
|
log.Fatalln("failed reading result:", err)
|
|
}
|
|
```
|
|
|
|
## Testing
|
|
|
|
The pgconn tests require a PostgreSQL database. It will connect to the database specified in the `PGX_TEST_CONN_STRING`
|
|
environment variable. The `PGX_TEST_CONN_STRING` environment variable can be a URL or DSN. In addition, the standard `PG*`
|
|
environment variables will be respected. Consider using [direnv](https://github.com/direnv/direnv) to simplify
|
|
environment variable handling.
|
|
|
|
### Example Test Environment
|
|
|
|
Connect to your PostgreSQL server and run:
|
|
|
|
```
|
|
create database pgx_test;
|
|
```
|
|
|
|
Now you can run the tests:
|
|
|
|
```bash
|
|
PGX_TEST_CONN_STRING="host=/var/run/postgresql dbname=pgx_test" go test ./...
|
|
```
|
|
|
|
### Connection and Authentication Tests
|
|
|
|
Pgconn supports multiple connection types and means of authentication. These tests are optional. They
|
|
will only run if the appropriate environment variable is set. Run `go test -v | grep SKIP` to see if any tests are being
|
|
skipped. Most developers will not need to enable these tests. See `ci/setup_test.bash` for an example set up if you need change
|
|
authentication code.
