Hello,

I am facing problem with the following piece of code that everytime it inserts in db (#ofRecords * 3)



I printed on tomcat console and output is:
JobId=>34
cvId=>8062
status=>1

JobId=>34
cvId=>8075
status=>1

I mean it showing correct results as I inserted two records whilst in database I see 6 records after this code. This code always insert (number of records * 3). Why?

Here how I calling this method


Here what am seeing through SQL:




The problem fixed as there was nothing wrong with the code but in database 3 records for each CVs were exists that was inserted with wrong code.

Sorry for inconvenience

Best regards

I'd suggest to add a primary key or unique constraints to prevent creating duplicates in the first place. This should expose the culprit (the code that tries to create the duplicates).
 
It is sorta covered in the JavaRanch Style Guide.
