How to validate an Email in Sql
hello :),
i want to validate emails in my database .. it means that if a user enters a non valid email format ( not like : [email protected] ) an error has to be executed ( like in a trigger )
actually i am working on a jdbc project .. and i did an insert statement, there i have to check if the email format is right before inserting ..

How to Validate Multiple email address in spry?
How to validate multiple email address in spry framework?
Spry validate text field can validate one email address only,
if I the text field is for multiple emails, how can I validate
it?Hello Jackson,
The Spry Textfield was designed to work with the normal work
flows that people currently use in most of the forms on the web. We
tried to prevent any email injection method in the forms therefore
the validation was designed to stop any multiple email insertion.
In case you want to insert multiple emails you'll have to
disable the default email validation and create your own validation
function, more flexible. You can see a
sample
we did for the custom validation trying to validate a password
strength and confirm the password.

Hi
In SQL under Management\Database Mail
You can configure account you use to send mails from SQL
Then you can prepare procedure that will send mail
for example
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'Hurtpol',
@recipients = '[email protected]',
@query = 'select isnull(syncherror,'''') collate polish_ci_as
from np.dbo.OITM
where U_SynchStatus=''Failed''',
--@body = @tresc,
@subject = 'synch error'

How to validate an email address against free domain users
Hi all,
I want to validate an email address so that only users of non free domains (let's say other than yahoo, hotmail, gmail, etc) can create an account in my apex application.
I want to place a validation on the "Registration Page" but I am not sure how to proceed from then on :(
Does anybody know how I can do this ?
Kind Regards,
Ana-MariaHi Ana-Maria,
You can do this on two places. You can do it on the client (using javascript) or you can do this on the database (using a trigger or a check constraint). The best way is to do both.
Use something like this for the javascript bit:
<script type="text/javascript">
function checkemail(){
var email = $v('P4_EMAIL');
//get index of @
var x = email.indexOf('@');
//get the string behind @
var behind_amp = email.substring(x+1, email.length);
//get the index of the .
var y = behind_amp.indexOf('.');
//filter out the provider
var provider = behind_amp.substring(0, y);
var result;
// set all wrong providers in this case
switch(provider){
case 'hotmail': result=false;break;
case 'yahoo': result=false;break;
case 'gmail': result=false;break;
// Check the result
if (!result){
//The provider is bad
alert(provider + ' is not allowed!');
//Keep the focus on the email field
setTimeout(function(){$x('P4_EMAIL').focus();}, 5);
</script>Set the event to the onchange of the email field (in HTML Form Element Attributes):
onchange="checkemail();"Hope this helps,

How to validate the Email string
Hi all,
How do you validate for a valid email string under regular expressions?
Regards
DavidHi,
Create an validation on EMAIL item and select Regular Expression as a validation method.
Write the below coding in the regular expression validation method.
^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*\.(\w{2}|(com|co.in|in|net|org|edu|int|mil|gov|arpa|biz|aero|name|coop|info|pro|museum))$

How to validate an email in jsp
Hi everyone, I am developing an web application in which i had to validate a user entered email address. Actually i developed some part of the code in jsp but its not so perfect because when a user enters more than one @ symbol,i am not able to detect it. Also there are some more bugs in it. So can anyone give me a sample code for this validation of an email-id. Also i heard that we have to use some regular expressions for this.Is it true? if so how? i need an idea.
Create an InternetAddress using the email string:
import javax.mail.InternetAddress;
InternetAddress email = new InternetAddress(emailString);or
InternetAddress email = new InternetAddress(emailString, true);If the address is not RFC822 valid, you should get an AddressException. If you set the address using the InternetAddress.setAddress(String s) method, then call validate(), which wil throw an AddressException on an invalid address. -
How to validate a email address using Validation Pattern?
Hi,
is there any document for Validation Pattern? i m looking for a way to validate email addresses in my form.
it's going to be something like * @ .
i have no idea of how to do this, or maybe validation pattern is no good? use java script instead?
any advice is appreciated!
thanks.Hi erv2,
You just need to place this script in the "exit" event of the field that u r using for email address.
var r = new RegExp(); // Create a new Regular Expression Object.
r.compile("^[a-z0-9_\\-\\.]+\\@[a-z0-9_\\-\\.]+\\.[a-z]{2,3}$","i");
if( this.rawValue == null || this.rawValue == "")
else
var result = r.test(this.rawValue);
if (result == true) // If it fits the general form,
true;
else
xfa.host.messageBox("Please enter a valid email address ");
this.rawValue = "";
false; // fail the validation.
Thanks

Hi all
i have a text input contains email
while save the record i need to check the filed that is valid email or not
at least one @ and .(dot) symbol should check
how its posible
Regards
SreeHi,
There are lot of regular expressions available on net. You can choose as per your requirement.
Following is an example which checks most of the email types.
public boolean validateEmail(String email) {
String regEx = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?";
//Set the email pattern string
Pattern p = Pattern.compile(regEx);
//Match the given string with the pttern
Matcher m = p.matcher(email);
//check whether match is found
boolean matchFound = m.matches();
return matchFound;

dbname.sqlSo i need to validate each and every .sql whether it succeed or not. if there is failure then needs to notify the user. Use the SQL*Plus macro/command, WHENEVER SQLERROR EXIT <n>, to terminate a sql script when it hits an error - and have it return a specific exit code to the caller (o/s command line in this case). Note that exit codes are typically defined as a single byte in shells - which means it can only returns 0 to 255.
In the command line shell, check the exit code of the previous command - which would be command than ran sqlplus and the sql script. If the exit code is for example 255, then you know the WHENEVER SQLERROR command was executed. And then you cease processing sql scripts.
Simplistically (I do not do Windows), it will look as follows:
--// sql script
whenever sqlerror exit 255
... rest of the script
@echo off
rem command shell script
prompt executing script 1
sqlplus -s /nolog @sqlscript1.sql
if ERRORLEVEL 255 goto :ScriptFailed
prompt executing script 2
sqlplus -s /nolog @sqlscript2.sql
if ERRORLEVEL 255 goto :ScriptFailed
goto :Success

echo ...
goto :End

How validate HTML using PL/SQL
Hi,
I try validate HTML using PL/SQL that user inputs.
I did create below function for that purpose
CREATE OR REPLACE
FUNCTION validate_html(
p_html IN VARCHAR2
) RETURN BOOLEAN
AS
l_comment XMLTYPE;
xml_parse_err EXCEPTION;
PRAGMA EXCEPTION_INIT (xml_parse_err , -31011);
BEGIN
l_comment := xmlType.createXML('<root><row>' || p_html || '</row></root>');
RETURN TRUE;
EXCEPTION WHEN xml_parse_err THEN
RETURN FALSE;
END;
Function works ok and return true if I run e.g.
BEGIN
IF validate_html('<p>Hello</p>') THEN
dbms_output.put_line('OK');
ELSE
dbms_output.put_line('Not valid HTML');
END IF;
END;
And return false if I enter not valid HTML like
BEGIN
IF validate_html('<p>Hello') THEN
dbms_output.put_line('OK');
ELSE
dbms_output.put_line('Not valid HTML');
END IF;
END;
But it return false also if I run below
BEGIN
IF validate_html('<p>Hello  </p>') THEN
dbms_output.put_line('OK');
ELSE
dbms_output.put_line('Not valid HTML');
END IF;
END;
Problem seems to be that   (there is ; in end but do not know how post it without forum convert that to space) witch is valid HTML for me.
I know that HTML is not XML, but can I use Oracle database XML functions for validating HTML?
How I should validate user inputted HTML?
I'm currently developing this using Oracle XE 11G database.
Regards,
JariNot an elegant way:
But try this.........
CREATE OR REPLACE FUNCTION validate_html (p_html IN VARCHAR2)
RETURN BOOLEAN AS
l_comment XMLTYPE;
xml_parse_err EXCEPTION;
PRAGMA EXCEPTION_INIT (xml_parse_err, -31011);
BEGIN
l_comment :=
xmlType.createXML (
'<root><row>'
|| CASE
WHEN INSTR (p_html, '&') > 0 THEN
UTL_I18N.escape_reference (p_html)
ELSE
p_html
END
|| '</row></root>');
RETURN TRUE;
EXCEPTION
WHEN xml_parse_err THEN
RETURN FALSE;
END;
SET DEFINE OFF
SET SERVEROUTPUT ON
BEGIN
IF validate_html ('<p>Hello') THEN
DBMS_OUTPUT.put_line ('OK');
ELSE
DBMS_OUTPUT.put_line ('Not valid HTML');
END IF;
END;
SET DEFINE OFF
SET SERVEROUTPUT ON
BEGIN
IF validate_html ('<p>Hello  </p>') THEN
DBMS_OUTPUT.put_line ('OK');
ELSE
DBMS_OUTPUT.put_line ('Not valid HTML');
END IF;
END;

How to validate Email Address in HTML DB Application
Hi,
I have delevoped one Employee Login Details form in HTML DB. But i am unable to validate that email address as i find html db is not supporting String functions like indexOf(char c), substring(int) ect. So please can anybody help me to know how to validate email address that it has @ and . symbol or not.
Thanks in advance.user529382,
You may be able to use Regular Expressions instead, if you do a search in this forum for 'regex' you should find a few hits.
While I agree that using a regular expression is a great way to verify that the user has entered an email address that conforms to the regular expression rules, it is still nothing more than that....conforming to the regular express rules.
The only way to 100% confirm that an email address is 'valid', is to actually send an email to it, so what I tend to do is to get the user to enter their email twice (in a user registration screen for example), that way you can minimize the chance of 'typos', then send out a 'verification email' that the user has to click a link on to verify they have received it (I'm sure you've seen this type of system before), only when the confirmation is received would I then make the account 'active'.
Hope this helps. -

It'll be complicated in pure SQL, as you'll have to parse out day, month and year and then validate the day against the month and year bearing in mind the rules for leap years.
