|
|
Package `gocqlx` is a Scylla / Cassandra productivity toolkit for `gocql`, it's
|
|
similar to what `sqlx` is to `database/sql`.
|
|
|
|
It contains wrappers over `gocql` types that provide convenience methods which
|
|
are useful in the development of database driven applications. Under the
|
|
hood it uses `sqlx/reflectx` package so `sqlx` models will also work with `gocqlx`.
|
|
|
|
## Installation
|
|
|
|
go get github.com/scylladb/gocqlx
|
|
|
|
## Features
|
|
|
|
Fast, boilerplate free and flexible `SELECTS`, `INSERTS`, `UPDATES` and `DELETES`.
|
|
|
|
```go
|
|
type Person struct {
|
|
FirstName string // no need to add `db:"first_name"` etc.
|
|
LastName string
|
|
Email []string
|
|
}
|
|
|
|
p := &Person{
|
|
"Patricia",
|
|
"Citizen",
|
|
[]string{"patricia.citzen@gocqlx_test.com"},
|
|
}
|
|
|
|
// Insert
|
|
{
|
|
q := Query(qb.Insert("person").Columns("first_name", "last_name", "email").ToCql())
|
|
if err := q.BindStruct(p); err != nil {
|
|
t.Fatal("bind:", err)
|
|
}
|
|
mustExec(q.Query)
|
|
}
|
|
|
|
// Update
|
|
{
|
|
p.Email = append(p.Email, "patricia1.citzen@gocqlx_test.com")
|
|
|
|
q := Query(qb.Update("person").Set("email").Where(qb.Eq("first_name"), qb.Eq("last_name")).ToCql())
|
|
if err := q.BindStruct(p); err != nil {
|

t.Fatal("bind:", err)
|
|
}
|

// Select

|
|
m := map[string]interface{}{
|
|
"first_name": []string{"Patricia", "John"},
|
|
}
|
|
if err := q.BindMap(m); err != nil {
|
|
t.Fatal("bind:", err)

}
|

var people []Person
|
|
if err := gocqlx.Select(&people, q.Query); err != nil {
|
|
t.Fatal(err)
|
|
}
|
|
t.Log(people)
|
|
|
|
// [{Patricia Citizen [patricia.citzen@gocqlx_test.com patricia1.citzen@gocqlx_test.com]} {John Doe [johndoeDNE@gmail.net]}]
|

}
