java - Verifying success for spring JDBC batch update -


i using spring jdbctemplate batchupdate insert data in batch. want verify if data inserted. jdbctemplate batchupdate returns int[][], right way verify data inserted?

this link says "all batch update methods return int array containing number of affected rows each batch entry. count reported jdbc driver , it's not available in case jdbc driver returns -2 value". unable understand significance of returning -2 value here. means insert unsuccessful?

-2 not mean error, might mentioned, case of count of affected rows not available.

edit

-2 value of statement.success_no_info (while execute_failed -3). unless driver not comply jdbc specification, -2 unequivocally means success

end of edit

the errors reported via batchupdateexception

normally, if run n queries in batch script count of updates per query in result:

int result[] = jdbctemplate.batchupdate(sql);

so:

result[0]

will hold update count first query,

result[1]

will hold update count second query etc.
