# 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)
|
||
|
}
|
||
|
```
|
