Firstly, importing Table to Geodatabase wasn't possible from the catalogue though I have successfully used it in the past. I get an error (Failed to connect to database. An underlying database error occurred. Class not registered) when I try to browse for the file. I resorted to Excel to Table and that has been successful. Then, currently, I am not able to create feature class from XY table. Nothing shows up in the drop down under the X,Y and Z fields. Any solution to these?
