very carefully.
I can't get you. Can you please elaborate?

I believe that's Daniel's way of giving as much information as he felt that you gave in your question :-)
Could you please provide a bit more information? What's the particular statement that causes this error, for example?
Thanks,
Adam
I am trying to export few tables from cluster A to cluster B. I can't go for backup & restoration as database name is different. But the Vertica version is same on both the cluster.
Few of the tables get exported successfully but some of them was not exported throwing the below error:
ERROR 3349: Expression for column ALERT_CLDR_DT cannot be coerced.
The same error is for those which are not exported with their respective column name.
So, I want to know what does it mean and how to resolve it?
Thanks in advance !!!!

Abhishek
I already checked the data types. They are same for both.

Target db name is vrt_dev.
Below is the command:
CONNECT TO VERTICA vrt_dev USER ebi_etlusr PASSWORD 'vertica123' ON '16.216.4.20',5433;
EXPORT TO VERTICA vrt_dev.RPT.WF_INCID_R As select * from RPT.WF_INCID_R ;
DISCONNECT vrt_dev;
ERROR 3349: Expression for column ALERT_CLDR_DT cannot be coerced.
The above command exported data successfully for almost all tables except few with the said error.
The ALERT_CLDR_DT column datatype and size is same on both source and target.

Abhishek

Version are same for source and target i.e 6.1.2Also you said if fails for some tables ?
Yes, I executed the same command to export other tables under same schema . For few tables it exported successfully but for few it fails with the same ERROR 3349.
Regards,
Abhishek
I also got the same error. Datatype is same in both source and destination tables. Only difference I see is in ordinal position of the column which is giving error. How to resolve this issue?
Regards,
Shridhar
Ordinal position mismatch can be solve by using COPY on top of view . Your data source will be a view on top of the original table , the view will have full match Ordinal position as the target table .
Thanks .
Ordinal position of the columns in source and target table might be different.can check the ordinal position number in tables(system table).
specifying the column names along with the copy command would solve the issue.
