Can anyone show how to concatenate two fields into one in this line of the TRIGGER T-SQL?:
INSERTED.(HeatTicketNumber,PO_Number)
>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>.
GO
SET QUOTED_IDENTIFIER ON
GO
ALTER TRIGGER [dbo].[trPopulateJournalEntries]
ON [dbo].[tblTransactions]
AFTER INSERT
AS
BEGIN
IF (SELECT Transaction_Type FROM INSERTED) = 'From Bulk Assignment'
INSERT INTO tblSWJournal
(tblSWJournal.Ledger,
tblBulkPurchases.Amt)
SELECT
INSERTED.(HeatTicketNumber,PO_Number)
INSERTED.Unit_Price
FROM INSERTED
END
GO

it would be simple concatenation;

if the types happen to be integers, you might need to convert them to varchars:

INSERT INTO tblSWJournal

(tblSWJournal.Ledger,

tblBulkPurchases.Amt)

SELECT

CONVERT(varchar(30),INSERTED.HeatTicketNumber)

+ ':'

+ CONVERT(VARCHAR(30),INSERTED.PO_Number),

INSERTED.Unit_Price

FROM INSERTED

In general it seems to not like something else that keeps popping up:

Msg 102, Level 15, State 1, Procedure trPopulateJournalEntries, Line 11

Incorrect syntax near '('.

looked a little deeper, this is a syntactically correct version that only inserts the rows that have INSERTED.Transaction_Type = 'From Bulk Assignment'

GO

SET QUOTED_IDENTIFIER ON

GO

ALTER TRIGGER [dbo].[trPopulateJournalEntries]

ON [dbo].[tblTransactions]

AFTER INSERT

AS

BEGIN

INSERT INTO tblSWJournal

(tblSWJournal.Ledger,tblBulkPurchases.Amt)

SELECT

CONVERT(VARCHAR(30), INSERTED.HeatTicketNumber) + ':' + CONVERT(VARCHAR(30), INSERTED.PO_Number),

INSERTED.Unit_Price

FROM INSERTED

WHERE INSERTED.Transaction_Type = 'From Bulk Assignment'

END

GO

Both the PO_Number and HeatTicketNumber are already Varchar as the table datatype... so (?) no need for conversion (?)...

I ran the code above and now have a SQL error popping up from my ASp.net app:

String or binary data would be truncated.

The statement has been terminated.

Check the datatype size of the VARCHAR columns compared to the PO_Number & HeatTicketNumber? Chances are one of those 2 columns is greater in length then what you have specified. That's what the error you got normally means?

Thought i would help you as I don't know you're exact skill level. Do a Length check on your data.

SELECT

LEN(ColumnName) AS StringLength

FROM

TableName

ORDER BY

StringLength DESC

What ever the biggest size it is needs to be less than the specified size on the VARCHAR(X)

I agree; the size of the field tblSWJournal.Ledger has to be at least as large as the maximum size of PO_Number & HeatTicketNumber & the separator ':'

in my example, that would be 61 characters (two varchar(30)'s plus the semicolon); you know what your real field sizes are; you'll need to change the tblSWJournal.Ledger size most likely.

review your data sized and fix whatever is invalid.
