[mapserver-users] MySQL connection: so near, yet so far...

[Chris Green]

I am trying to establish a MySQL connection to a Mapserver 6.0 layer using
OGR. After much trial and error (mostly error) I have got to the point where
I have an ovf file which I can test using ogrinfo, but which I cannot make
work in a layer.

My ovf file (OGR_test.ovf) is  

<OGRVRTDataSource>
    <OGRVRTLayer name="OGR_test">
	
<SrcDataSource>mysql:testDB,user=root,password=mysql,port=3306,tables=testTa
ble</SrcDataSource>
        <SrcSQL>SELECT City, Latitude, Longitude FROM testTable</SrcSQL>
        <GeometryType>wkbPoint</GeometryType>
        <GeometryField encoding="PointFromColumns" x="Longitude"
y="Latitude"/>
    </OGRVRTLayer>
</OGRVRTDataSource>

I can successfully test this and see the data in testTable via:

~# ogrinfo var/www/vhosts/mysite/httpdocs/data/OGR_test.ovf


However when I create a test layer I cannot establish the OGR connection. I
am trying with:

LAYER
  NAME "testLayer"
  STATUS DEFAULT
  TYPE POINT
  CONNECTIONTYPE OGR
  CONNECTION "OGR_test.ovf"
  DATA "OGR_test"
  CLASS
    NAME "MyClass"
    STYLE
      SYMBOL 'circle'
      SIZE 15
      COLOR 0 255 0
    END
  END
END

This produces an "internal server error".

I have also tried using an absolute path to OGR_test.ovf, still no success.
It seems that I have not got the CONNECTION and DATA parameters right but
after reading the MySQL and the OGR sections in the Mapserver documentation
many times I still can't figure out what I'm doing wrong.

Can someone help?


Regards,



Chris

It seems I celebrated too soon.....although this now succeeds:

~# ogrinfo mysql:testDB,user=root,password=mysql,port=3306 

...when I try to create an ovf file like so:

<OGRVRTDataSource>
    <OGRVRTLayer name="testLayer">
 
<SrcDataSource>mysql:testDB,user=root,password=mysql,port=3306,tables=testTa
ble</SrcDataSource>
        <SrcSQL>SELECT City, Latitude, Longitude FROM testTable</SrcSQL>
        <GeometryType>wkbPoint</GeometryType>
        <GeometryField encoding="PointFromColumns" x="Longitude"
y="Latitude"/>
    </OGRVRTLayer>
</OGRVRTDataSource>


I get the error "Unable to open datasource
'var/www/vhosts/mysite/httpdocs/OGR_test.ovf' with the following drivers."
This is followed by the list of drivers which includes MySQL.

Something wrong in my ovf file?

Hi,

Try first by removing the space characters after separating commas.

Aihe: [mapserver-users] Mapserver layer - MySQL connection

Hi all

I’m using Mapserver 6.0 and I have GDAL  1.8.0 installed, running under
Ubuntu 10.04.  I am trying to make a connection from a layer to MySQL,
following the guidance given in the MySQL section of Mapserver
documentation. My problem is that when I try to connect using ogrinfo like:

~# ogrinfo mysql:testDB, user=root, password=mysql, port=3306

I get a mySQL connect failure message “ERROR 1: MySQL connect failed for:
testDB, Access denied for user’root’@’localhost’ (using password: NO)”

It seems that MySQL is refusing this connection request because the password
that I entered in the ogrinfo command is not being passed to MySQL and I
can’t find a way to overcome this. The same user name and password work fine
if I access MySQL directly rather than via ogrinfo.

Does anyone have an idea what my problem is?



Chris
