[HELP] Count all data in a table in SQLITE3

[kadel]

Using MySQL would be

MySQLCursor, err = MySQLConnection:execute("SELECT COUNT(*) FROM Students WHERE YearID='"..sYearID.."' ");
if not err then
Count = MySQLCursor:fetch({},"n");
Dialog.Message("Notice", Count[1], MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
else Dialog.Message("Error", err); return "Error"; end

Hey telco ,
Would help if you posted example of your apz or at least example db
off top of my head maybe try something like this

testCount = 0
-- loop until we get all the information from database
local q = "SELECT * FROM FROM Students WHERE YearID = '"..sYearID.."' "
for row in db:nrows(q) do
--Get the data by fields from the database
 nCount = row.YearID
    if nCount == 3 then
    testCount = testCount + 1
end

Dialog.Message("Notice", tostring(testCount), MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);

[telco]

testCount = db:exec("SELECT COUNT(*) FROM Students WHERE YearID = '"..sYearID.."' ) ")

result = Dialog.Message("Notice", tostring(testCount), MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);


i have more than 20 students save in specific year level but in the dialog message it only returns 1 item.

can anyone help me get the correct syntax to count all students in specific year?




Thank you so much
