import ( "github.com/go-xorm/xorm" _ "github.com/lib/pq" ) func main() { engine, err := xorm.NewEngine("postgres", "myconnectionstring") if err != nil { // handle error } engine.SetId("mydbengine") // ... }
session := engine.NewSession("mydbengine") // ...
queryBuilder := engine.Table("mytable").Where("id = ?", 123).And("name = ?", "foo").Engine("mydbengine") // ...In this example, we use the engine's ID "mydbengine" when accessing the query builder. We create a new query that operates on the "mytable" table and adds two criteria to the WHERE clause (id = 123 and name = "foo"). The resulting query can be executed using the query builder's `Query` or `Find` methods. Overall, the `github.com.go-xorm.xorm` package library provides a robust set of tools for working with relational databases in Go, and its Engine ID mechanism allows users to manage and interact with multiple databases using a unified API.
