Std.Db.Row

15 public declarations

• at&Std.Db.Driver.Rows -> Int -> Int -> Result[Std.Db.Driver.Value, Std.Db.Row.RowError]

  The value at a row and column, both counted from zero.

  fn
• bytes&Std.Db.Driver.Rows -> Int -> Str -> Result[Bytes, Std.Db.Row.RowError]

  A named column read as raw bytes.

  fn
• decimal&Std.Db.Driver.Rows -> Int -> Str -> Result[Decimal, Std.Db.Row.RowError]

  A named column read as an exact decimal.

  fn
• indexOf&Std.Db.Driver.Rows -> Str -> Result[Int, Std.Db.Row.RowError]

  Named access refuses duplicate labels, which require aliases or indexed access.

  fn
• integer&Std.Db.Driver.Rows -> Int -> Str -> Result[Int64, Std.Db.Row.RowError]

  A named column read as a whole number.

  fn
• map&Std.Db.Driver.Rows -> fn(Std.Db.Driver.Rows, Int) -> Result[T, Std.Db.Row.RowError] -> Result[Array[T], Std.Db.Row.RowError]

  Mapping order follows the result; the first mapper failure stops consumption.

  fn
• Mapper

  Turns one row into a value, or says why it could not.

  type
• nullable&Std.Db.Driver.Rows -> Int -> Str -> Result[Option[Std.Db.Driver.Value], Std.Db.Row.RowError]

  None means a present SQL NULL, never a missing column or malformed row.

  fn
• one&Std.Db.Driver.Rows -> fn(Std.Db.Driver.Rows, Int) -> Result[T, Std.Db.Row.RowError] -> Result[T, Std.Db.Row.RowError]

  The single row a query answered, or an error when it answered none or several.

  fn
• optional&Std.Db.Driver.Rows -> fn(Std.Db.Driver.Rows, Int) -> Result[T, Std.Db.Row.RowError] -> Result[Option[T], Std.Db.Row.RowError]

  The one row a query answered, or nothing. Several rows is an error.

  fn
• real&Std.Db.Driver.Rows -> Int -> Str -> Result[Float64, Std.Db.Row.RowError]

  A named column read as a binary floating number.

  fn
• RowError

  Why a value could not be read out of a result set.

  type
• text&Std.Db.Driver.Rows -> Int -> Str -> Result[Str, Std.Db.Row.RowError]

  A named column read as text. A null is an error, not an empty string.

  fn
• truth&Std.Db.Driver.Rows -> Int -> Str -> Result[Bool, Std.Db.Row.RowError]

  A named column read as a truth value.

  fn
• value&Std.Db.Driver.Rows -> Int -> Str -> Result[Std.Db.Driver.Value, Std.Db.Row.RowError]

  The value in a named column of a row, whatever its kind.
