Column

Column is a structure used to create table's columns.

prototype
struct Column {    char name[3];    char* type;  };

  1. name: the column name - no more than 2 char. And we count also null terminated sequence \0 as a character.

  2. type: the column type. Read more about TinyDatabase types

example
Column ag = {"ag", "INT"};Column rt = {"rt", "FLOAT"};Column tm = {"tm", "ULONG"};
Column allCols[] = {ag, rt, tm};
// or directly Column myCols[] = {                    {"ag", "INT"},                    {"rt", "FLOAT"},                    {"tm", "ULONG"}                };

Here we create 03 columns named ag, rt and tm of types INT, FLOAT and ULONG.

String#

We don't support arduino String data type. But a good support for array char is provided. So you can convert a String to an array of char and use TinyDatabase. Read more about TinyDatabase types to know more about char[].
