Why am I getting this error. Can someone help me. Thank you

Best answer by Ethem Q

@DougN Nouria I understand your reasoning however what we wanted to clarify here is the end goal in order to suggest any viable solutions that might help @loisine.ann.mendoza for what they are looking to accomplish. 

As a matter of fact, the team in care of Sync advises against using NOLOCK hints because utilizing the `WITH (NOLOCK)` hint is equivalent to setting the transaction isolation level to `READ UNCOMMITTED`. This approach risks reading uncommitted data, which may later be rolled back, resulting in the replication of data that does not persist in the source database. While this method can prevent read operations from being blocked by other transactions, it introduces the risk of retrieving data that is not finalized, and this is one of the reasons why we do not employ this function.

In any case, there have been now a few requests about this functionality and a ticket has been already submitted for looking into adding this feature. This request will first be evaluated by the product team and it might take some time before they come to a decision if they want to pursue this. We will be sure to notify you once there is an update.

    What is the source (database, file, etc.) connection?  Any questions like this will be highly dependent on what you are doing.

     

    Have you tried executing a similar query in whatever querying tools are available to you, and do you get the same error?

    SELECT TOP 100000 * FROM [dbo].[App_History] AS [WITH] WHERE [ID] > [whatever] ORDER BY [ID] ASC

      The source is cdata sql and the destination is bigquery.
      This is replicate query script= REPLICATE [history] SELECT * FROM [dbo].[App_History] AS  WITH(NOLOCK);

          Hi @loisine.ann.mendoza 

          Based on the information you have provided, the main cause of the issue you are encountering is the custom REPLICATE query that you are running:

          REPLICATE [history] SELECT * FROM [dbo].[App_History] AS WITH(NOLOCK);

          First of all the above query is not quite correct. The correct query should be: REPLICATE [history] SELECT * FROM [dbo].[App_History] WITH(NOLOCK)

          In any case, it appears that passthrough queries similar to these are not currently supported in Sync, so we are unfortunately unable to formally use the queries with NOLOCK present. Since this query is not supported by Sync, it is being transformed to a different query for some reason which I can notice from the logs you have included:

          REPLICATE [history_test] WITH _id = 'JckazNKQyY8YpKv9Y5RdeA==' SELECT * FROM [dbo].[App_History] AS [WITH]]

          It looks like an ALIAS is added incorrectly at the end of the custom REPLICATE query and this is causing the "The SQL Error Number is 102, State is 1, Severity is 15, Error is 'Incorrect syntax near 'ca1'.', Server name is AWDAPPINDB3, Line number is 1.The Token Type is 170" error message. I can reproduce the same error on my end when running a similar query which would indicate that the  AS [WITH] being appended at the end of the custom query is causing this.

          With that being said, are you able to replicate the table correctly when omitting the WITH(NOLOCK) from your custom query?

          Also, is there any particular reason why you are using WITH(NOLOCK) hints here? Would you be able to provide more context on that? We would be interested to hear more what is your end goal?

          On a side note, I wanted to point out that NOLOCK hints shouldn't be required generally because Sync isn't going to put a lock on your entire database during the replication process. We essentially are submitting an elegant SELECT query against your source SQL database. Select queries should generally only place a shared lock on each row as the database processes those records for the corresponding query at most. Sync shouldn't be enforcing any kind of lock on your database anyway. That shouldn't be a concern with Sync.

          In case you have any other questions or are unclear about something feel free to reach out to our support team at [email protected] and one of our support members will further assist you.

            @Ethem Q    Assuming the OP is using SQL Server, since we’re talking (NOLOCK) hints.

            With SQL Server, if you’re retrieving many thousands of rows even on a SELECT statement, it will place a read table lock on the entire table.  Lock escalation.  And that read lock will prevent writes.  It won’t block other readers, but it does block updates.  It’s just not as sophisticated as Oracle in that regard, in my experience.

            It will do this even if the user login for the CData connection doesn’t have write privileges to the database.

              Hi @Ethem Q i tried REPLICATE [history] SELECT * FROM [dbo].[App_History] WITH(NOLOCK) and without no lock but still got the error but data still ingested. The settings is Drop table is enabled, history is enabled and not enable still same error.  I attached the log files for you reference.

                You probably shouldn’t include log files here, as they could contain sensitive information.

                Your likely best bet, at this point, is to enter a formal support request through the web site, versus using the community support forum.

                  @DougN Nouria I understand your reasoning however what we wanted to clarify here is the end goal in order to suggest any viable solutions that might help @loisine.ann.mendoza for what they are looking to accomplish. 

                  As a matter of fact, the team in care of Sync advises against using NOLOCK hints because utilizing the `WITH (NOLOCK)` hint is equivalent to setting the transaction isolation level to `READ UNCOMMITTED`. This approach risks reading uncommitted data, which may later be rolled back, resulting in the replication of data that does not persist in the source database. While this method can prevent read operations from being blocked by other transactions, it introduces the risk of retrieving data that is not finalized, and this is one of the reasons why we do not employ this function.

                  In any case, there have been now a few requests about this functionality and a ticket has been already submitted for looking into adding this feature. This request will first be evaluated by the product team and it might take some time before they come to a decision if they want to pursue this. We will be sure to notify you once there is an update.
