Hi All
You will have to excuse my relatively simple question but i am new to playing
with Sqlite and databases in general.
I have a little app that is using PHP and Sqlite. I have had no troubles
getting all the basics working but have hit a wall with the BLOB datatype.
What i am trying to acheive is to store a sequence of bytes in my table.
I am a little unsure about how to exactly store and retrieve that data. My
confusion is coming from the fact that i have inherited this project from a
previous employee who only just started the project and i cannot understand why
he has done what he has done.
My example is as:
$sql= "CREATE TABLE users (
key INTEGER PRIMARY KEY,
username BLOB,
password BLOB,
level BLOB);";
$result = $dbh->query($sql);
for ($count=0;$count<$users_num;$count++)
{
$sql= "INSERT INTO users (key, username, password, level)
VALUES ('".$count."', 'TEXT(21)||||||||', 'TEXT(21)||||||||',
'INTEGER|0|0|0|0|0|0|0');";
$result = $dbh->query($sql);
}
I don't understand why he used the format he did to insert default values into
the table. I have searched the net high and low and for the life of me i cannot
find one example where someone did something like 'INTEGER|0|0|0|0|0|0|0'.
If someone could help explain to me how i can access the "level" bytes and or
update them that would be great. I simply dont know why he put the INTEGER into
values.
Thanks Steve.
