Is it possible to not specify the data type in a sqlite table cell?

Question

SQLite

it seems like the typing is dynamic

$sql = "CREATE TABLE t1(
      	c1 TEXT,
      	c2 TEXT
      );";

can it be shortened to:

$sql = "CREATE TABLE t1(
      	c1,
      	c2
      );";

or put TEXT and then, for example, assign numbers

Answer 1

No. Each table column must have a specific type.

Answer 2

yes, by assigning the text type to the field, you can write numbers into it
when you try to write text into the numeric field - this will also work
