rofl what.

Let's say you have 20 properties.
You first execute 1 query to get all properties. Then loop through them and keeping a counter to get the amount of properties.
Then you have the number, 20. Then you're going to make another loop that's going to make 20 queries to get the Pos etc. from each property.

This could be done with just 1 query. Which you already made.

function LoadProps()
{ 
    local q = QuerySQL( db, "SELECT * FROM Props" ), a = 0;
    while ( GetSQLColumnData( q, 0 ) )
    {
        local Pos = GetSQLColumnData( q, 1 ).tostring();
        CreatePickup( GetSQLColumnData( q, 0 ).tointeger(), Vector( GetTok( Pos, " ", 1 ).tofloat(), GetTok( Pos, " ", 2 ).tofloat(), GetTok( Pos, " ", 3 ).tofloat() ) );
        GetSQLNextRow( q );
        a++;
    }
    FreeSQLQuery( q );

    print( "Loaded: " + a + " props." );
}

The error you got probably means your "db" variable isn't defined globally.

Thanks, fixed.
