I'm writing a script to insert a GUID into a SQL table. In order to stop duplicates, I have made the table GUID column unique.
So now I need to catch the violation and ignore if its a duplicate and continue the script. So write the new GUIDS but ignore the duplicates.
What would be the best way to catch and deal with the violation?
I've seen a few options on this site, but none work for me, most fail with The Catch block is missing its statement block. or other errors.
Example of the catch block I've been trying
catch(SqlException ex)
{
sqlException = ex.InnerException as System.Data.SqlClient.SqlException;
if (sqlException.Number == 2601 || sqlException.Number == 2627)
{
ErrorMessage = "Cannot insert duplicate values.";
}
else
{
ErrorMessage = "Error while saving data.";
}
}
and the errors:
At D:\Software Approval Requests\GetApprovalRequestsNew2.ps1:15 char:6
+ catch (UpdateException ex)
+ ~
The Catch block is missing its statement block.
At D:\Software Approval Requests\GetApprovalRequestsNew2.ps1:18 char:32

I am using CloseableHttpAsyncClient for downloading image with socketreadtimemout of 10 sec , connect timeout 5sec and doing a retry if it fails with sockettimeout and Timeout exception.
Now when the url is not accessible(404) then instead of resource not found exception it is failing with socket timeout and doing a retry again.So in my case for this invalid url also we are trying again and it adds up to the latency(~10+10=20 sec).
Below is the code snippet
Future<HttpResponse> httpResponseFuture = asyncCloseableHttpClient.execute(httpUriRequest, null);
try {
return httpResponseFuture.get(10000, TimeUnit.MILLISECONDS);
} catch (ExecutionException e) {
Throwable cause = e.getCause() != null ? e.getCause() : e;
if (cause instanceof ConnectException) {
throw new DownloadConnectionException("ConnectionException " + cause, DOWNLOAD_FAILED, cause);
}
if (cause instanceof SocketTimeoutException) {
throw new DownloadTimeoutException(DOWNLOAD_TIMEOUT_EXCEPTION);
}
if (cause instanceof ConnectionClosedException) {
throw new DownloadConnectionClosedException("ConnectionClosedException " + DOWNLOAD_FAILED, cause);
}
if(cause instanceof UnsupportedCharsetException) {
throw new BadRequestException("Image download failed with UnsupportedCharsetException " + cause,
INVALID_CONTENT_TYPE_EXCEPTION, cause);
}
} catch (TimeoutException e) {
throw new DownloadTimeoutException(DOWNLOAD_TIMEOUT_EXCEPTION);
}
This the config values for CloseableHttpAsyncClient
RequestConfig config = RequestConfig.custom()
.setSocketTimeout(10000)
.setConnectTimeout(5000)
.setRedirectsEnabled(true)
.setMaxRedirects(3)
.setStaleConnectionCheckEnabled(false) // never set this to true, 30 ms extra per request
.setProxyPreferredAuthSchemes(Arrays.asList(AuthSchemes.BASIC))
.build();
This is retry config
RetryConfig.custom().maxAttempts(downloadAttempts).retryOnException(e -> ( e instanceof DownloadTimeoutException) ) .waitDuration(Duration.ofMillis(30)).build();
To give more context why I am setting the socketreadtimemout of 10 sec because let's say for some bigger image download it may fail 1st time,so in that case retry is valid scenario but not in the resource not found case.
Can we do anything to make resource not found/invalid url fail fast so that it wont fail with sockettimeout exception.
I am using Typehandler to map a List<Dep> to oracle array of ... here is the setPArameter method in the handler :
public void setParameter(PreparedStatement ps, int i, List<Dep> parameter, JdbcType jdbcType)
throws SQLException {
Connection connection = ps.getConnection();
// StructDescriptor structDescriptor = StructDescriptor.createDescriptor("MEMS_ARR", connection);
Struct[] structs = null;
if(parameter != null && parameter.size() >0) {
structs = new Struct[parameter.size()];
for (int index = 0; index < parameter.size(); index++)
{
Dep dep = parameter.get(index);
Object[] params = new Object[7];
params[0] = dep.getOrder();
params[1] = dep.getIdTp;
params[2] = dep.getId();
params[3] = " ";
params[4] = " ";
params[5] = " ";
params[6] = " ";
// STRUCT struct = new STRUCT(structDescriptor, ps.getConnection(), params);
structs[index] = connection.createStruct("MEMS", params);
}
// ArrayDescriptor desc = ArrayDescriptor.createDescriptor("MEMS_ARR", ps.getConnection());
// ARRAY oracleArray = new ARRAY(desc, ps.getConnection(), structs);
}else {
parameter = new ArrayList<DependentDTO>();
structs= new Struct[0];
}
this.parameter = parameter;
Array oracleArray = ((OracleConnection) connection).createOracleArray("MEMS_ARR", structs);
ps.setArray(i, oracleArray);
}
and here is the MEMS type :
create or replace TYPE MEMS AS OBJECT
( MEM1 NUMBER(2,0),
MEM2 VARCHAR2(1),
MEM3 VARCHAR2(15),
MEM4 VARCHAR2(60),
MEM5 VARCHAR2(1),
MEM6 VARCHAR2(40),
MEM7 VARCHAR2(10)
);
and here is the portion of the xml mapping file that uses the Typehandler :
#{nat,javaType=String,jdbcType=VARCHAR,mode=IN}, --nat
**#{deps,javaType=List,jdbcType=ARRAY,mode=IN,jdbcTypeName=MEMS_ARR,typeHandler=com.my.package.MyHandler}, --mems**
#{res,javaType=String,jdbcType=VARCHAR,mode=OUT} --res
the error log is as follows :
Error querying database. Cause: java.sql.SQLException: ORA-06550: line 31, column 5: PLS-00103: Encountered the symbol "" when expecting one of the following: . ( ) , * # % & = - + < / > at in is mod remainder not rem => <an exponent (**)> <> or != or ~= >= <= <> and or like like2 like4 likec between || indicator multiset member submultiset The symbol "(" was substituted for "" to continue. ORA-06550: line 44, column 4: PLS-00103: Encountered the symbol ";" when expecting one of the following: .

As you can see in the logs, the mems is replaced by empty string or is merged with the next arg res ... the comma is not there
Also kindly note that I already debugged inside the mybatis code and realized that the mapping setParameter method is called and the input List is mapped correctly to the oracle array ... the issue happens at the time of real calling
The issue actually was that I simply missed one comma between two previous parameters ... but the error pointed to the wrong parameter to look at
I'm new to coffeescript and I'm not sure what is wrong with my syntax. I want to add an error message if either the date or time field is empty upon clicking the update button. Here is my code.
$.add_error = (field, message) ->
unless field.hasClass('input-error')
field.after('<span class="input-error-message">' + message + '</span>')
field.addClass('input-error')
$.remove_error = (field) ->
field.removeClass('input-error')
field.parent().find('.input-error-message').remove()
$('.btn.update_schedule').click ->
date = $('#date')
time = $('#time')
if (date.val() && !time.val()) || (!date.val() && time.val())
if !time.val()
$.add_error(repeat_count, 'Please select both a date and time')
false
else !date.val()
$.add_error(repeat_date, 'Please select both a date and time')
false
else
$.remove_error(time) || $.remove_error(date)
I'm unable to compile this code because it says there's an unexpected indentation but I don't see it. Any advice would be greatly appreciated.
In the last block $('.btn.update_schedule').click ->, there is an
if ... else ... else ...
that is basically non-sense.
It seems that should be instead an
if ... else if ... else ...
This seems the correct version:
$('.btn.update_schedule').click ->
date = $('#date')
time = $('#time')
if (date.val() && !time.val()) || (!date.val() && time.val())
if !time.val()
$.add_error(repeat_count, 'Please select both a date and time')
false
else if !date.val()
$.add_error(repeat_date, 'Please select both a date and time')
false
else
$.remove_error(time) || $.remove_error(date)

Do you have any proposition of workaround ? or another way to set URI attribute ?
Thank you for helping !
I found it.
I added InclusiveNamespaces so that the sign method can figure out that ID is on a specific namespace defined attribute.
have spent lot of hours trying to figure this out with Paypal Simulator, Sandbox but the result is same. My handler function(handleIpn) gets called and processed, with "Verified" "Complete" status but the IPN history as well as the simulator ends up in the HTTP 404 error.

thanks.
Finally, got it working! Didn't realize that my issue of redirection in Spring MVC could have impact on Paypal - IPN status. May be my lack of good understanding of HTTP redirections! In above method instead of void return am now returning a jsp page, so "void" is changed to "String" with returning value the jsp file name.
Hope it does help someone!
