import ( "github.com.youtube.vitess/go/sqltypes" ) func getData() ([]sqltypes.Value, error) { // database query code here rows, err := db.Query("SELECT column1, column2 FROM table") if err != nil { return nil, err } defer rows.Close() // Iterate over rows and get values var data []sqltypes.Value for rows.Next() { var val1, val2 string err := rows.Scan(&val1, &val2) if err != nil { return nil, err } data = append(data, sqltypes.MakeString(val1), sqltypes.MakeString(val2)) } return data, nil }The example above shows a function that queries a database and returns an array of Value types. The `MakeString` function of the sqltypes package is used to create a Value type with a string value. In summary, the `github.com.youtube.vitess.go.sqltypes` package provides a way to represent values returned from a database query. This package is often used together with a database driver to query a database and process the results.
