I can't believe I am struggling with this as I have other implementations doing this exact same thing but for some reason my join is not working correctly or as expected.The process peforms a join between a FeatureClass in a FGDB and an "in_memory" table. The table(s) is created with ExtractValuesToTable_ga, so I have a "SrcID_Feat" field that matches up to the FeatureClass' "OBJECTID_1" field. If I output the table(s) to disk and perform the exact same join it works just fine. However, with the same exact parameters defined using arcpy.AddJoin_management the join fails.Well, it joins just fine but the joined fields are empty and no errors.I am wondering if there is some difference in field names? If I print out the field names during runtime, they all look good (exactly as they are if they are coming from the tables on disk).Stuck.
gridLyrName = "gridFC"
if arcpy.Exists( r"C:\Extract.gdb\Transects_Selector"):
glyr = r"C:\Extract.gdb\Transects_Selector"
arcpy.MakeFeatureLayer_management(glyr, gridLyrName)
arcpy.env.workspace = "in_memory"
arcpy.env.overwriteOutput = True
tabs = arcpy.ListTables()
for t in tabs:
if "tab" in t:
memtab = "trans_" + t
arcpy.MakeTableView_management(t, memtab)
arcpy.AddJoin_management(gridLyrName, "OBJECTID_1", memtab, "SrcID_Feat", "KEEP_ALL")
arcpy.CopyFeatures_management(gridLyrName, r"C:\Extract.gdb\\" + memtab)
arcpy.RemoveJoin_management(gridLyrName)
