<br><tt><font size=2>Hi,<br>
<br>
We have to draw and query a map which is based on an arcsde database.<br>
<br>
Case 1:<br>
I want to query an object, which is of type point. The objects are in an<br>
<br>
arcsde geodata-server, which I connect with the following statement:<br>
<br>
CONNECTION "xxx.dcnv.xxx.de,port:5151,sde,xxx,xxx"<br>
CONNECTIONTYPE SDE<br>
DATA "xxx.xTS,SHAPE,SDE.DEFAULT"<br>
<br>
As a result I get the following error: <br>
<br>
Content-type: text/html msSDELayerGetShape(): SDE error. <br>
SE_stream_fetch_row(): Invalid parameter value passed to function. (-66)<br>
<br>
There is a great number of points which I do have to query, and there<br>
are also <br>
cases (points) , which might have a NULL-field within the list of<br>
attributs <br>
for a specific point. <br>
<br>
If I query objects which are polygon type everything is fine, i.e. I<br>
don't get <br>
any errors.<br>
<br>
Case 2:<br>
I want to draw another layer based on the same connection statement,<br>
i.e. also <br>
point object in an arcsde database. The attribut are of type <br>
SE_INT32. When I issue an EXPRESSION statement , i.e. <br>
EXPRESSION ([WINKEL] > 0 ),<br>
mapserver complains this with the error message<br>
<br>
msyyparse(): Expression parser error. syntax error<br>
msEvalExpression: Expression parser error. Failed to parse expression:<br>
<null> <br>
> 0<br>
<br>
What do I do wrong? <br>
Or, is there an error in the sde database?<br>
Mapserver was build including arcsde library sdeexe92 and use the<br>
configure <br>
statement " --with-sde-version=92"<br>
<br>
I really would appreciate any ideas in solving these errors.<br>
<br>
Ludger<br>
