Sqlite dbPoll

[Hero192]

Can anyone explain why we should use this type? and why we should do return

function checking(ACC) 
    local query = dbQuery(connection, "SELECT * FROM data WHERE name = '" ..tostring(ACC) .. "'") 
    local result = dbPoll(query,-1) 
    if ( type( result ) == "table" and #result > 0 ) or not result then 
        return true --Why this?  
    else 
        return false -- WHy this? to return what 
    end 
end

You don't need to return anything, dbPoll is used to get the result of a dbQuery.

[...] Use the returned query handle with dbPoll to get the result, or dbFree if you don't want the result

obs: if you're calling checking() in another function then the return is necessary

This is a simple MySQL query that checks if something is in the table. If it found what you were looking for it is going to return true ( so you can execute your code ) but if it didn't find anything it will return false ( your code is not going to execute ).
