SQL Trigger to send an email - sql-server

Question

I need to créate a trigger in a SQL table to send an email if the inserted record meets certain conditions.
That is, I create the trigger in Table1 to send an email to X if in the inserted record the field IdCircuito= 53, IdTipoDoc = 45 and Gestor = 'Gest1'. Also, in the body of email message I want the value of a certain field of that inserted record to appear. I have done something like this but trigger always executes regardless of the inserted record:
CREATE TRIGGER dbo.SendEmail
ON dbo.TitulosDoc
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
IF EXISTS (SELECT 1 FROM TitulosDoc WHERE IdCircuito = 53 AND IdTipoDoc = 45 AND Gestor = 'Gest1')
BEGIN
EXEC msdb.dbo.sp_send_dbmail
#recipients = 'rsg#gmail.com',
#subject = 'New requeriment',
#body = 'It's a new requeriment: ';
END
END
GO
In body is where I want show a literal text with the value of the field of inserted record:
#body = 'It's a new requeriment: ' + TitulosDoc.NombreDocumento;
Can somebody help me? Thank you

To access the inserted row you need to select from INSERTED.
Try this:
CREATE TRIGGER dbo.SendEmail
ON dbo.TitulosDoc
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
DECLARE #NombreDocumento VARCHAR(MAX) = (SELECT INSERTED.NombreDocumento
FROM INSERTED
WHERE INSERTED.IdCircuito = 53
AND INSERTED.IdTipoDoc = 45
AND INSERTED.Gestor = 'Gest1')
IF #NombreDocumento IS NOT NULL
BEGIN
EXEC msdb.dbo.sp_send_dbmail
#recipients = 'rsg#gmail.com',
#subject = 'New requeriment',
#body = 'It''s a new requeriment: ' + #NombreDocumento;
END
END
GO

I would do what Sean Lange said... create a physical table called TempTitulosDoc, then insert your records to it that need to be sent through email. Do this in your trigger.
CREATE TRIGGER dbo.SendEmail
ON dbo.TitulosDoc
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
BEGIN
INSERT INTO TempTiulosDoc(field1, field2, EmailStatus)
SELECT field1, field2, 0 AS EmailStatus --Email NOT sent
FROM TitulosDoc
WHERE IdCircuito = 53 AND IdTipoDoc = 45 AND Gestor = 'Gest1'
END
END
GO
Create a stored procedure like this that loops through those records and sends an email. When done, update the TempTitlosDoc with a status of 1 signifying a sent email.
DECLARE #loopCount INT
DECLARE #field1 VARCHAR(10)
DECLARE #field2 VARCHAR(10)
DECLARE #EmailStatus int
--Create Temp Table
CREATE TABLE #Temp
(
id int not null identity,
field1 VARCHAR(10),
field2 VARCHAR(10),
EmailStatus int
)
--Insert Tasks to temp table
INSERT INTO #Temp (field1, field2, EmailStatus)
SELECT field1, field2, EmailStatus
FROM dbo.TempTiulosDoc
WHERE Status = 0
--Set a loopCount for while loop
SET #loopCount = 1
--Use the while loop to check if we have any Tasks left to send
while ( exists(SELECT id FROM #Temp WHERE id = #loopCount) )
BEGIN
--Get current record in temp table
SELECT #field1 = field1,
#field2 = field2,
#EmailStatus = EmailStatus
FROM #Temp
WHERE id = #loopCount
EXEC msdb.dbo.sp_send_dbmail
#recipients = 'rsg#gmail.com',
#subject = 'New requeriment',
#body = 'It''s a new requeriment: ' + #NombreDocumento;
--Update your work table with the status of 1 so it's not picked up again
UPDATE teq
SET teq.#EmailStatus = 1
FROM dbo.TempTiulosDoc teq
WHERE teq.id = #field1
SET #loopCount = #loopCount + 1
END
