"Column 'PK1' not found" at iAnywhere.Data.SQLAnywhere.SACommand.ExecuteNonQuery()

Question

Presently, I am working with this trigger:

CREATE TRIGGER "TrigUploadEmailInspectionInsert" AFTER INSERT
ORDER 1 ON "EmailInspectionQuery"
REFERENCING OLD AS initial NEW AS updated 
FOR EACH ROW
BEGIN
    DECLARE count int;
    IF f_are_triggers_enabled() = 1 THEN
      SELECT Count(PK1) INTO count FROM TransactionUpload
      WHERE PK1 =  updated.ID AND TYPE = 'EMAIL_QUERY';
      CASE
        WHEN count = 0 THEN
         INSERT INTO TransactionUpload (PK1, PK2, TYPE, ACTION, ACTION_SEQ, UPD_TMSTP, UI_SAVE_STATUS) 
     VALUES ( PK1, 'N/A', 'EMAIL_QUERY', 'I', 0, CURRENT TIMESTAMP, NULL )
      END CASE;  
    END IF;
END

Here are the table details:

TransactionUpload
TYPE,12,nvarchar(12),N
PK1,255,nvarchar(255),N
PK2,12,nvarchar(12),N
ACTION_SEQ,4,integer,N
ACTION,1,nvarchar(1),N
MOBILE_STATUS,10,nvarchar(10),Y
MOBILE_STATUS_SET_INACT,1,nvarchar(1),Y
UPD_TMSTP,8,timestamp,Y
SYNC_SAVE_STATUS,1,char(1),Y
UI_SAVE_STATUS,1,char(1),Y
ASYNC_PROCESSING,1,char(1),Y
MYSAPSSO2,1024,char(1024),Y

EmailInspectionQuery
column_name,width,base_type_str,nulls
ID,12,nvarchar(12),N
CR_DATE,8,timestamp,Y
ERNAME,12,nvarchar(12),Y
AUFNR,12,nvarchar(12),Y
INSP_DUE,8,timestamp,Y
INSP_STATUS,20,nvarchar(20),Y
EQUNR,18,nvarchar(18),Y
HEQUIPMENT,128,nvarchar(128),Y
HOPEN_RECOMMENDATIONS,1,char(1),Y
HTERRITORY,30,nvarchar(30),Y

When I run the C#/.NET source code that involves inserting data into EmailInspectionQuery I get this error, but it doesn't make any sense to me because TransactionUpload clearly has a PK1 column. Here is the exception:

ex.InnerException.InnerException {"Column 'PK1' not found"}

    TargetSite: {Int32 ExecuteNonQuery()}

Does anyone have any suggestions? TIA.

Found the problem, needed to change this line:

INSERT INTO TransactionUpload (PK1, PK2, TYPE, ACTION, ACTION_SEQ, UPD_TMSTP, UI_SAVE_STATUS) 
     VALUES ( PK1, 'N/A', 'EMAIL_QUERY', 'I', 0, CURRENT TIMESTAMP, NULL )

To,

INSERT INTO TransactionUpload (ID, PK2, TYPE, ACTION, ACTION_SEQ, UPD_TMSTP, UI_SAVE_STATUS) 
     VALUES ( updated.ID, 'N/A', 'EMAIL_QUERY', 'I', 0, CURRENT TIMESTAMP, NULL )
