I need a simple bit of AMPscript to serve up one type of email salutation where the First Name exists in the database and one where I don't.
So, IF Firstname is null: "Hello," - IF Firstname is not null: "Dear #Firstname"
Embarrassingly, everything I've tried hasn't worked. I'm aware that this is a painfully simple bit of AMPscript
Here's how I'd do it:
%%[
var #firstName
set #firstName = AttributeValue("firstName")
]%%
<!-- some other HTML -->
%%=iif(empty(#firstName),"Hello", concat("Dear ", propercase(#firstName)))=%%,
Reference:
attributevalue
iif
empty
concat
propercase

I've been playing around with Substring, left, right, charindex and can't quite get this to work
If this is the value in column name 'Data' (this is all one line)
{"email":{"RecipientId":"usertest","RecipientEmail":"test#test.com","Subject":"This is a test subject heading","RecipientSubject":"A recipient subject"}}
How do I do a SELECT statement to find the 'Subject' heading and then get the data 'This is a test subject'? The Subject value is different for every record so I just can't look for 'This is a test subject'.
So the end result should be This is a test subject for that SELECT result
The following query should do what you want:
declare #string varchar(max);
set #string = '{"email":{"RecipientId":"usertest","RecipientEmail":"test#test.com","Subject":"This is a test subject heading","RecipientSubject":"A recipient subject"}}';
select substring(#string,charindex('"Subject":',#string)+11,charindex('"RecipientSubject"',#string)-charindex('"Subject"',#string)-13);
The plain and easy-cheesy approach is this:
SELECT SUBSTRING(
t.YourString
,A.StartPosition
,CHARINDEX('"'
,t.YourString
,A.StartPosition+1) - A.StartPosition
)
FROM #dummyTable t
CROSS APPLY(SELECT CHARINDEX('"Subject":"',t.YourString)+11) A(StartPosition)
I use APPLY to calculate a value and use it like you'd use a variable. The idea is: Find the starting point and look for the closing quote from there. But this will break, whenever the content includes an (escaped) quote like in
"Subject":"This is \"quoted\" internally"
A more generic approach
Starting with v2016 JSON-support was introduced. With this (or a higher) version this is really simple:
Use this mockup-table for testing
DECLARE #dummyTable TABLE (YourString VARCHAR(1000));
INSERT INTO #dummyTable VALUES('{"email":{"RecipientId":"usertest","RecipientEmail":"test#test.com","Subject":"This is a test subject heading","RecipientSubject":"A recipient subject"}}');
--The OPENJSON-method will read this for you:
SELECT JsonContent.*
FROM #dummyTable t
CROSS APPLY OPENJSON(t.YourString,'$.email')
WITH(RecipientId VARCHAR(100)
,RecipientEmail VARCHAR(100)
,[Subject] VARCHAR(100)
,RecipientSubject VARCHAR(100)) JsonContent;
But with a lower version you will need to trick this out. It is the easiest, to tranform JSON to attribute centered XML like here:
<email RecipientId="usertest" RecipientEmail="test#test.com" Subject="This is a test subject heading" RecipientSubject="A recipient subject" />
We can achieve this by some string methods and I must warn you, that there are several pit-falls with forbidden characters and other stuff... Just try it out:
SELECT Casted.ToXml.value('(/email/#RecipientId)[1]','varchar(1000)') AS RecipientId
,Casted.ToXml.value('(/email/#RecipientEmail)[1]','varchar(1000)') AS RecipientEmail
,Casted.ToXml.value('(/email/#Subject)[1]','varchar(1000)') AS [Subject]
,Casted.ToXml.value('(/email/#RecipientSubject)[1]','varchar(1000)') AS RecipientSubject
,Casted.ToXml.query('.') LookHowThisWasTransformed
FROM #dummyTable t
CROSS APPLY
(
SELECT CAST(CONCAT('<email '
,REPLACE(REPLACE(REPLACE(REPLACE(t.YourString,'{"email":{"',''),'}}',''),'","','" '),'":"',' ="')
,' />') AS XML)
) Casted(ToXml);
Hi i am getting the string literal error when i am trying to add an attribute to the child node. How can i modify my code in order to add an attribute successfully.
declare #count int=(select mxGraphXML.value('count(/mxGraphModel/root/Cell/#Value )','nvarchar') from TABLE_LIST
where Table_ListID=1234 )
declare #index int=1;
while #index<=#count
begin
declare #Value varchar(100)= #graphxml.value('(/mxGraphModel/root/Cell/#Value )[1]','nvarchar');
SET #graphxml.modify('insert attribute copyValueID {sql:variable("#Value ")}
as first into (/mxGraphModel/root/Cell)['+convert(varchar,#index)+']');
end
set #index=#index+1;
end
You're using the addition operator where you should be using the CONCAT function. So
'insert attribute copyValueID {sql:variable("#Value ")}
as first into (/mxGraphModel/root/Cell)['+convert(varchar,#index)+']'
is being coerced into a number. Try:
CONCAT('insert attribute copyValueID {sql:variable("#Value ")}
as first into (/mxGraphModel/root/Cell)[',convert(varchar,#index),']')
instead.
Adam, you can do it in Microsoft T-SQL like this:
declare #sql nvarchar(max)
set #sql = 'set #myxml.modify(''
insert (
attribute scalableFieldId {sql:variable("#sf_id")},
attribute myTypeId {sql:variable("#my_type_id")}
) into (/VB/Condition/Field[#fieldId=sql:variable("#field_id")
and #fieldCode=sql:variable("#field_code")])['+
cast(#instance as varchar(3))+']'')'
exec sp_executesql
#sql
,N'#myxml xml output, #field_code varchar(20),
#field_id varchar(20), #sf_id int, #my_type_id tinyint'
,#myxml = #myxml output
,#field_code = #field_code
,#field_id = #field_id
,#sf_id = #sf_id
,#my_type_id = #my_type_id
See what I've done here? It's just a clever usage of Dynamic SQL to overcome Microsoft's moronic limitation of "string literal error".
IMPORTANT NOTE: yes, you can MOSTLY do this by using sql:variable() in SOME places BUT good luck trying to use it in the node number qualifier inside the square brackets! You can't do this without Dynamic SQL by design!
The trick is not mine actually, I got the idea from https://www.opinionatedgeek.com/Snaplets/Blog/Form/Item/000299/Read after banging my head against the wall for a while.
Feel free to ask questions if my sample does not work or something is not clear.
How to verify the email is valid or not?
For example:
test#test.com - valid
test##.com - invalid
test#.com - invalid
Here is an example of creating a table with specific rules for mail with address (regexp). Then an example with sql query pattern (Regexp). With this you should be able to do what you want
Create table with regexp
create table Contacts (
FirstName nvarchar(30),
LastName nvarchar(30),
EmailAddress nvarchar(30) CHECK (dbo.RegExMatch('[a-zA-Z0-9_\-]+#([a-zA-Z0-9_\-]+\.)+(com|org|edu|nz)', EmailAddress)=1),
USPhoneNo nvarchar(30) CHECK (dbo.RegExMatch('\([1-9][0-9][0-9]\) [0-9][0-9][0-9]\-[0-9][0-9][0-9][0-9]', UsPhoneNo)=1))
INSERT INTO [talend].[dbo].[Contacts]
([FirstName]
,[LastName]
,[EmailAddress]
,[USPhoneNo])
VALUES
('Hallam'
,'Amine'
,'mhallam#talend.com’
,'0129-2090-1092')
,( 'encoremoi'
,'nimportequoi'
,'amine#zichji.org'
,'(122) 190-9090')
GO
Execute request sql with regexp
SELECT [FirstName]
,[LastName]
,[EmailAddress]
,[USPhoneNo]
FROM [talend].[dbo].[Contacts]
where [talend].[dbo].RegExMatch([EmailAddress],'[a-zA-Z0-9_\-]+#([a-zA-Z0-9_\-]+\.)+(com|org|edu|nz|au)') = 1
Function Code
using System;
using Microsoft.SqlServer.Server;
using System.Text.RegularExpressions;
public partial class RegExBase
{
[SqlFunction(IsDeterministic = true, IsPrecise = true)]
public static int RegExMatch( string matchString , string pattern)
{
Regex r1 = new Regex(pattern.TrimEnd(null));
if (r1.Match(matchString.TrimEnd(null)).Success == true)
{
return 1 ;
}
else
{
return 0 ;
}
}
};

I hope this help you
There is one newer efficient way to do that is to extend .Net functionality for SQL.
Please check details at http://msdn.microsoft.com/en-us/magazine/cc163473.aspx
One ready source code for regex match is at http://www.codeproject.com/Articles/42764/Regular-Expressions-in-MS-SQL-Server-2005-2008.
Now a simple regex for Email should do the magic for you
Hope that helps
Some years back I wrote a program about Pattern Matching – Email Validation. Hope that may help you.
I have written a function which takes the Name as input and returns Suffix.
I want to return the position of suffix in a name with a function.
How can i do that.
Could any one please help me doing it.
there is no need to create special function fot this. it already exists in t-sql.
its name is PATINDEX
Example:
declare #pat varchar(128)
set #pat = '_suf'
select login, Patindex('%'+#pat, login) as suffix_index from clients
I have an optional field in a database that I'm pulling out using a DAO Record Set. I need to check whether or not the field is set before I concatenate it with other fields. So far I have the following code snippet which I've tried with both Is and = (that's the obviously wrong syntax [[Is | =]]) to no avail. It appears that if I use = it will not correctly compare with Null and if I use Is then it complains that it's not comparing with an Object.
While Not rs.EOF
If rs.Fields("MiddleInitial") [[Is | =]] Null Then thisMiddleInitial = "" Else thisMiddleInitial = rs.Fields("MiddleInitial")
If prettyName(myLastName, myFirstName, myMiddleInitial) = prettyName(rs.Fields("LastName"), rs.Fields("FirstName"), thisMiddleInitial) Then
MsgBox "Yay!"
End If
rs.MoveNext
Wend
If there's a simpler way to do this I'm totally open to it. prettyName takes 3 Strings as parameters and initially I was just trying to pass rs.Fields("MiddleName") directly but it threw up at a Null value. I'd prefer to do something more direct like that but this is the best I could come up with.
How about:
IsNull(rs.Fields("MiddleInitial").Value)
You could also have a look at this article which has some explanation about Null values in Access VBA apps and how to handle them.
For the example you show, Nz would work:
thisMiddleInitial = Nz(rs!MiddleInitial,"")
Or simply concatenating the string with an empty string:
thisMiddleInitial = rs!MiddleInitial & ""
Your question has been answered by Remou, seems to me, but it occurs to me that you may just be trying to get proper concatenation of the name fields. In that case, you could use Mid() and Null propagation in VBA to get the result.
I don't use separate middle initial fields, so my usual name concatenation formula is:
Mid(("12" + LastName) & (", " + FirstName), 3)
The "12" string at the beginning is going to be tossed away if LastName is Not Null and ignored if it is null, because the + concatenation operator propagates Nulls.
To extend this to include middle intials would look like this:
Mid(("12" + LastName) & (", " + FirstName) & (" " + MiddleInitial), 3)
Assuming your UDF is not doing some kind of complicated cleanup of nicknames/abbreviations/etc., this could replace it entirely, seems to me.
If rst.Fields("MiddleInitial").Value = "Null" Then
This works for me. I use MS SQL Database.
I think the NoMatch option might work in this situation:
If rs.NoMatch = True Then
I prefer using the below to account for both Null and Empty string values. It's a good check to use you have forms collecting values from users.
If Trim(rs.Fields("MiddleInitial") & "") = "" then
