Row

A struct to represent a single row of a result set.

The row struct is used for both 'traditional' and 'prepared' result sets. It consists of parallel arrays of Variant and bool, with the bool array indicating which of the result set columns are NULL.

I have been agitating for some kind of null indicator that can be set for a Variant without destroying its inherent type information. If this were the case, then the bool array could disappear.

struct Row {

import mysql.connection;;

package

Variant[] _values;

this(Connection con, ubyte[] packet, ResultSetHeaders rh, bool binary);

inout(Variant) opIndex(size_t i);

bool isNull(size_t i);

size_t length [@property getter];

alias opDollar = length;

void toStruct(S s);

void show();

}

Constructors

this this(Connection con, ubyte[] packet, ResultSetHeaders rh, bool binary): A constructor to extract the column data from a row data packet.

Members

Aliases

opDollar alias opDollar = length: Get the number of elements (columns) in this row.

Functions

isNull bool isNull(size_t i): Check if a column in the result row was NULL
opIndex inout(Variant) opIndex(size_t i): Simplify retrieval of a column value by index.
show void show(): Undocumented in source. Be warned that the author may not have intended to support it.
toStruct void toStruct(S s): Move the content of the row into a compatible struct

Properties

length size_t length [@property getter]: Get the number of elements (columns) in this row.
