This guide demonstrates how to use the Xray library to inspect a MySQL database in a Go application.
Xray is a library that provides tools for inspecting and analyzing various types of databases. In this example, we'll use Xray to connect to a MySQL database, retrieve the schema for each table, and generate SQL queries.
-
Define Database Configuration
Add your MySQL Database configuration to your Go application:
Note : Set env variable DB_Password for adding password and pass your password as :
export DB_PASSWORD=your_password
import ( "github.com/thesaas-company/xray/config" "github.com/thesaas-company/xray/types" "github.com/thesaas-company/xray" ) // Define your database configuration here dbConfig := &config.Config{ Host: "127.0.0.1", Database: "employees", Username: "root", Port: "3306", SSL: "false", }
Note : Ensure to replace the placeholders with your actual database configuration.
-
Connect to MySQL Database
client, err := xray.NewClientWithConfig(dbConfig, types.MySQL) if err != nil { panic(err) }
-
Retrieve Table Schema
data, err := client.Tables(dbConfig.Database) if err != nil { panic(err) }
-
Print Table Schema
for _, tableName := range data { table, err := client.Schema(tableName) if err != nil { panic(err) } fmt.Println(table) }
-
Generate Create Table Query
generate and print SQL CREATE TABLE queries for each table in the response slice.
// Iterate over each table in the response slice. for _, v := range response { // Generate a CREATE TABLE query for the current table. query := client.GenerateCreateTableQuery(v) // Print the generated query. fmt.Println(query) }
-
Execute Queries
Execute queries against your database:
query := "SELECT * FROM my_table" // Specify your SQL query result, err := client.Execute(query) if err != nil { fmt.Printf("Error executing query: %v\n", err) return } fmt.Printf("Query result: %s\n", string(result))
