Overview ¶
Package dw is a wrapper layer.
This package gives you wrappers of sql.DB, sql.Tx and ef package functions.
Most functions/methos are helpers to ef package functions. This package gives you fewer arguments and transparency to sql.DB methods. e.g.
before: db, _ := sql.Open(...) stmt := cue.Select(...) query, args := stmt.BuildSQL() ef.FetchOne(db, &destStruct, query, args...) after: db, _ := dw.Open(...) // same arguments stmt := cue.Select(...) // same db.FetchOne(&destStruct, stmt) // fewer lines, fewer arguments
