I have an assignment which requires me to join attributes in a geodatabase with a csv table just like what is mentioned in this About joining and relating tables—Help | ArcGIS for Desktop . I have a matching key called CDE_BLK but I can't seem to find the matching key when I tried to join the gdb and csv table.
I suspect it might be due to the differences in data type of the matching key in both the gdb and csv table, where the matching key in the gdb is a Text and the one in the csv table is a Long.
I tried to change the CDE_BLK field to Text format in the csv file but whenever I add it into ArcMap, it will return to Long. Does anyone have any idea on how to make this work? Thanks a lot for your help!
