# Go wrapper for [DuckDB CLI](https://duckdb.org/docs/api/cli/overview)

* Doesn't require CGO.

* Requires duckdb cli to be in the path.

## In Memory Database

```

	db := NewInMemoryDB()

	commands := []string{

		"CREATE TABLE t1 (i INTEGER, j INTEGER);",

		"INSERT INTO t1 VALUES (1, 5);",

		"SELECT * from t1;",

	}

	res, err := db.RunCommands(commands)

```

## File based Database

```

	db := NewDuckDB("foo")

	commands := []string{

		"CREATE TABLE t1 (i INTEGER, j INTEGER);",

		"INSERT INTO t1 VALUES (1, 5);",

	}

	_, err := db.RunCommands(commands)

	res, err := db.Query("SELECT * from t1;")

```

## Dataframes

* Allows querying dataframes using SQL, with all the aggregate/window/analytics functions from DuckDB.

## Query Dataframes

```

	db := NewInMemoryDB()

	var values = []string{"test"}

	frame := data.NewFrame("foo", data.NewField("value", nil, values))

	frame.RefID = "foo"

	frames := []*data.Frame{frame}

	res, err := db.QueryFrames("foo", "select * from foo", frames)

```
