Problems using the where clause with searchcursor method

Hello all,

I am using ArcGIS Desktop 10.0 and I am  trying to write a script in python.

I am having problems with the where clause in the searchcursor method.

Basically I have a CAD file and would like to identify from the CAD file all of the Annotations that have been flagged with a  ??????? question mark.

So if I have the following list of Annotations in the Text filed of the Annotation CAD feature class, I would like to pull out the 3rd 5th and 6th rows using search cursor:


I have managed to get the where clause in the search cursor to identify individual records but it keeps failing.  I have attached an example of the CAD file and also the script.

I believe that the problem may be that the ???question mark??? is confusing the where clause.  I have tried to escape the non standard characters and also writing the where clause as a variable but do not seem to be getting anywhere.

If anyone could help it would be really appreciated, I copy my script below......



import arcpy
from arcpy import env
env.workspace = r"C:\CADfile.dwg"

#This does not work: cur = arcpy.SearchCursor("Annotation",'LEFT("Text",1)='[\\?]'',"","","")
#This works: cur = arcpy.SearchCursor("Annotation","\"Text\" = \'69570020\'")
#This works: cur = arcpy.SearchCursor("Annotation",'"Text" < \'1\'')

cur = arcpy.SearchCursor("Annotation",'\"Text\" LIKE \'\?\%\'\')

# Iterate through the rows in the cursor
for row in cur:
    print "Layer: %s,  Parcel: %s" % \
            (row.Layer, row.Text)

del cur, row
