This is an example code that demonstrates how to use prepared SQL queries that aids to speeding up your API responses. This code shows how to execute a simple SQL query to retrieve data from an in-memory SQLite database and return it as JSON.
This code uses the Gin-Gonic web framework to handle HTTP requests. When the server receives a GET request for the /name
endpoint, it reads the id
parameter from the query string, executes a SQL query to retrieve the corresponding data from the SQLite database, and returns the result as JSON.
The SQL query is prepared in advance using the db.Prepare
function, which compiles the query into a reusable statement that can be executed multiple times. The stmt.QueryRow
function is then used to execute the prepared statement with the given id
parameter, and the result is scanned into a variable using the Scan
function.
To run this code, you'll need to have Go installed on your machine. You can then download or clone the repository and run the following command:
go run main.go
This will start the server on port 8081. You can then send a GET request to http://localhost:8081/name?id=1
to retrieve the data for the id=1
record from the database.
