pawn Код:

format(string, sizeof(string), "UPDATE `Groups` SET `Name`='%s' WHERE `GroupID`='%i'", strval(inputtext), value);

`Name`='%s' is a string and you use strval.

The right query:

pawn Код:

format(string, sizeof(string), "UPDATE `Groups` SET `Name`='%s' WHERE `GroupID`='%i'", inputtext, value);

And here, value is integer, not a string.

pawn Код:

printf("Faction name: %s:", value);
