Friends! I need to create a trigger to perform the following action:

When you insert new data in the (Employee) table, the trigger must check if there is already a row in the table (Assistance) with "Date" and "Id_Employee" of equal value that entered into the (Employee) table THEN:

1 - If not exist, create a new row in the table (Assistance) with the values ??entered in the (Employee) table:
Assistance.Date = Employee.Date AND Assistance.Id_Employee = Employee.Id_Employee, then the values of
"IN" and "OUT" from table (Employee) if "Order" is 1 the values will in "IN_AM" and "OUT_AM"
in the Assitance table, if "Order" is 2 the values will in "IN_PM" and "OUT_PM".

2 - If exist, only need to update the values ??of the fields [IN_AM, OUT_AM] or [IN_PM, OUT_PM], depending on whether order is 1 or 2

Employee <------TABLE 1
---------------------------------------------
Id_Employee--Order--IN-----OUT----Date
21866........1......07:55..12:05..4/10/2013
21866........2......12:55..17:01..4/10/2013
05214........1......08:05..12:15..4/10/2013
05214........2......13:00..17:08..4/10/2013
=============================================

Assistance <------TABLE 2
-----------------------------------------------------------
Date------Id_Employee----IN_AM----OUT_AM----IN_PM----OUT_PM
4/10/2013..21866.........07:55....12:05.....12:55....17:01
4/10/2013..05214.........08:05....12:15.....13:00....17:08
===========================================================

After creating the trigger if I try to enter data in the Employees table:

INSERT INTO Employee(Id_Empleado, Date, Order, IN, OUT)
VALUES(21866,'14/10/2013 0:00:00',1,'14/10/2013 07:57:00','14/10/2013 12:10:00')

I get the following:
....in Trig_ModifyData. Line 6:
- Error converting character string to smalldatetime data type.

Column Employee Table:
---------------------------------------
- Id_Employee (vachar(7), NO NULL)
- Date (smalldatetime, NO NULL)
- IN (smalldatetime, NULL)
- OUT (smalldatetime, NULL)

Column Assitance Table:
---------------------------------------
- Id_Employee (vachar(7), NO NULL)
- Date (smalldatetime, NO NULL)
- IN_AM (smalldatetime, NULL)
- OUT_AM (smalldatetime, NULL)
- IN_PM (smalldatetime, NULL)
- OUT_PM (smalldatetime, NULL)

I try this in the trigger:
...
AND Date = CONVERT(smalldatetine, i.Date)
...

but not work.... :(

1 is enough

you just need a boolean result to see if record exists or not

why are you doing the conversion? Isnt field datetime? you should make it datetime as its delaing with date values

The conversion was a test, with it or without it I get the same error:
....in Trig_ModifyData. Line 6:
- Error converting character string to smalldatetime data type.

and truth, not understand why because the corresponding fields are smalldatatime data type.

If I remove the trigger, I can run the query to insert data seamlessly
INSERT INTO Employee(Id_Employee, Date, Order, IN, OUT)
VALUES(21866,'14/10/2013 0:00:00',1,'14/10/2013 07:57:00','14/10/2013 12:10:00')


The strange thing is that I can run this query directly in the table Assistance:

INSERT INTO Asistance(Id_Employee, Date, IN_AM, OUT_AM, IN_PM, OUT_PM)
VALUES(21866,'15/10/2013 0:00:00', '15/10/2013 07:57:00', '15/10/2013 12:05:00',
'15/10/2013 12:53:00', '14/10/2013 17:10:00')

Somehow the trigger is sending a string instead of smalldatatime

can you try using iso format for passing dates and see if it works?

ie like


INSERT INTO Employee(Id_Employee, Date, Order, IN, OUT)
VALUES(21866,'20131014 00:00',1,'20131014 07:57','20131014 12:10')

Neither works well, says the same error:
Mens 295, Level 16, Status 3, Prossesing Trig_ModifyData, Línea 6
Error converting character string to smalldatetime data type.

Anyway I need that data can be sent as follows: '14/10/2013 0:00:00'

You can perform a data conversion within the trigger to fix the problem?

I should not do the conversion on the trigger but as I said before, the trigger will send the value of a field (smalldatatime) of the Employee table to a field too (smalldatatime) in the table Assistance
I do not understand why it is giving error

I did the following test without the trigger to insert data from Employee table to Assistance table and run correctly:

INSERT INTO Assistance(Id_Employee, Date, IN_AM, OUT_AM)
SELECT Id_Employee, Date, IN, OUT
FROM Employee WHERE Date='16/10/2013 0:00:00' AND Order = '1'

Then why trigger not run? :(

Supposedly, what should I convert to smalldatetime data in the trigger to prevent the error?

Is Date smalldatetime in both the tables Employee and Assistance?

yes, yes!, Date, IN, OUT, IN_AM, OUT_PM, are smalldatetime


By the way, when I add the trigger, SQL Server automatically adds lines "**"
** set ANSI_NULLS ON
** set QUOTED_IDENTIFIER ON
** GO
** ALTER TRIGGER [dbo].[Trig_ModifyData]
** ON [dbo].[Employee]
FOR INSERT
AS
BEGIN
INSERT Assistance
SELECT Date, Id_Employee,
...

Based on your explanation you've no chance of getting this error. So its onvious that you're missing something or you may have some other code which you've not shown us so far

Ok,! look the real tables:

Table 1 As Employee table:

http://www.subirimagenes.net/i/131028034827199744.png

Table 1 The Columns! :
As "Id_Employee" = Id_Empleado
As "Date" = Fecha
AS "Order" = OrdenTurno
As "IN" = MarcaEntrada
As "OUT" = MarcaSalida



Table 2 As Assitance table:

http://www.subirimagenes.net/i/131028033956990112.png

Table 2 the Columns:
As "Id_Employee" = Id_Empleado
As "Date" = Fecha


As "IN_AM" = Entada_AM
As "OUT_AM" = Salida_AM

As "IN_PM" = Entada_PM
As "OUT_PM" = Salida_PM


THEN the trigger is:


set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[Trig_OrganizarFirmas]
ON [dbo].[CPT_TarjetaAsistencia]
FOR INSERT
AS
BEGIN 
INSERT CPT_AsistenciaEmpleados
SELECT Fecha, Id_Empleado,
MAX(CASE WHEN [OrdenTurno] = 1 THEN MarcaEntrada END) AS EntradaAM,
MAX(CASE WHEN [OrdenTurno] = 1 THEN MarcaSalida  END) AS SalidaAM,
MAX(CASE WHEN [OrdenTurno] = 2 THEN MarcaEntrada END) AS EntradaPM,
MAX(CASE WHEN [OrdenTurno] = 2 THEN MarcaSalida  END) AS SalidaPM
FROM INSERTED i
WHERE NOT EXISTS (SELECT 1 FROM CPT_AsistenciaEmpleados
WHERE Id_Empleado = i.Id_Empleado
AND Fecha = i.Fecha)
GROUP BY Id_Empleado,Fecha

UPDATE a
SET EntradaAM = i.EntradaAM,
SalidaAM = i.SalidaAM,
EntradaPM = i.EntradaPM,
SalidaPM = i.SalidaPM
FROM CPT_AsistenciaEmpleados a
INNER JOIN (
SELECT Fecha, Id_Empleado,
MAX(CASE WHEN [OrdenTurno] = 1 THEN MarcaEntrada END) AS EntradaAM,
MAX(CASE WHEN [OrdenTurno] = 1 THEN MarcaSalida END) AS SalidaAM,
MAX(CASE WHEN [OrdenTurno] = 2 THEN MarcaEntrada END) AS EntradaPM,
MAX(CASE WHEN [OrdenTurno] = 2 THEN MarcaSalida END) AS SalidaPM
FROM INSERTED i
GROUP BY Id_Empleado,Fecha
)i
ON i.Id_Empleado = a.Id_Empleado
AND i.[Fecha] = a.[Fecha]
END



See if you see because it gives me the error

i think i got the issue. Reason is your order in SELECT is different from column order in INSERT
Try this and see

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[Trig_OrganizarFirmas]
ON [dbo].[CPT_TarjetaAsistencia]
FOR INSERT
AS
BEGIN 
INSERT CPT_AsistenciaEmpleados
SELECT Id_Empleado,Fecha, 
MAX(CASE WHEN [OrdenTurno] = 1 THEN MarcaEntrada END) AS EntradaAM,
MAX(CASE WHEN [OrdenTurno] = 1 THEN MarcaSalida  END) AS SalidaAM,
MAX(CASE WHEN [OrdenTurno] = 2 THEN MarcaEntrada END) AS EntradaPM,
MAX(CASE WHEN [OrdenTurno] = 2 THEN MarcaSalida  END) AS SalidaPM
FROM INSERTED i
WHERE NOT EXISTS (SELECT 1 FROM CPT_AsistenciaEmpleados
WHERE Id_Empleado = i.Id_Empleado
AND Fecha = i.Fecha)
GROUP BY Id_Empleado,Fecha

UPDATE a
SET EntradaAM = i.EntradaAM,
SalidaAM = i.SalidaAM,
EntradaPM = i.EntradaPM,
SalidaPM = i.SalidaPM

Well, no longer fails when a row is inserted, the trigger sends the data to the other table :) .

But I see that does not work when you modify the row, ie when the row is updated, the trigger does nothing

I had changued this:

..
UPDATE a
....
..
SELECT Fecha, Id_Empleado,
...


for this


..
UPDATE a
....
..
SELECT Id_Empleado, Fecha,
...
