creating tables in php leads to errors in phpmyadmin....

[Maze]

hello Jaques1

 

 - just again farom this lovley internet-cafe in southern-spain .,...

 

 

thanks for clearing up.

 

you set my thouthgs straingth - i want to gather data from openstreetmap..

 

Again many many thanks for this great asset of db-knowledge. <

 

 

i think that i can go with the fixed solution - and this will fit all the needs.

 

if there is no result - i.e. no value for a specific tag then there is null in DB..

 

that is no problem for me - so it goes well if i go with the data...

 

 

many greetings

 

guess that the main questions of this thread are answerd

many many tahnks for all the help...!!

some addtional notes:

 

some examples.: btw: the key question is, how can we write the request: that takes up the adress-tags correctly: http://wiki.openstreetmap.org/wiki/Key:addr  while trying to gather information about european schools - note i try it with different approaches with the target-goal to gather

name
adress
long
lat
and town, street, housenumber information
and then - if possible website -adress
 and if there are some more tags available then these too.

so - as you Jaques1 mentioned - i go with the fixed db sheme and will catch as much as i can.

in oother words - i will create a table with maxiumum of the tag/value combinations - in order to catch all ....

Barand is already gave you a solution here. Gizmola is wrong b/s your structure is the same as Jacques1 stated above.

hello jazzmann hello jaques1 hello all

 

 

many thanks @ jazzmann for the hint - yes youre right - this hint was given by barand

 

he said: Instead of hard-coding the required column names as in

$fields = array('id','lat','lon','name','amenity','operator','vending');

and continued ..... you could use this to pick up any additional columns added to your pois  table

$sql = "SHOW COLUMNS FROM pois";
$fields = array();
$res = $db->query($sql);
while ($row = $res->fetch_row()) {
$fields[] = $row[0];
}

i think that this does the trick..

 

gizmola - gae osome hints and ideas regarding mongodb:

well i do not know mongodb but i guess that barands hints were solving the issues.

 

many many thanks for all your contineued help and your supportive way of inspiring me.

 

this forum is great - and you helped me quite alot!!!

 

greetings
