A packaged set of Goland database operation methods

Using native Golang for database crud feels a lot of the same, so referencing the customary usage of database classes before,
encapsulates a set of database action methods:

Package Libimport ("Database/sql" _ "Github.com/go-sql-driver/mysql" "Strings" "FMT") type Dbrow map[string]in Terface{}type Dblib struct {db *sql. Db}func newdblib (Driver, DSN string) (*dblib, error) {db, err: = SQL. Open (Driver, DSN) if err! = Nil {return nil, err} err = db. Ping () if err! = Nil {return nil, err} p: = new (Dblib) p.db = db return P, Nil}func scanrow (rows * Sql. rows) (Dbrow, error) {columns, _: = Rows. Columns () Vals: = Make ([]interface{}, Len (Columns)) Valsptr: = Do ([]interface{}, Len (Columns)) for I: = Range V als {Valsptr[i] = &vals[i]} err: = rows.    Scan (Valsptr ...) If err! = Nil {return nil, err} r: = Make (Dbrow) for I, V: = Range Columns {if VA, ok: = Vals[i] . ([]byte); OK {R[v] = string (VA)} else {r[v] = vals[i]}} return R, nil}//gets a row of records func ( D *dblib) GetOne (SQL string, args ... interface{}) (Dbrow, errOR) {rows, err: = D.db.query (sql, args ...)

If err! = Nil {return nil, err} defer rows. Close () Result: = Make ([]dbrow, 0) for rows.
