Exception when querying data with INTERVAL TO SECOND column type

Exception when querying data with INTERVAL TO SECOND column type

Postby Namit » Tue 01 Oct 2013 19:59

I am getting Arithmetic Overflow exception when querying data from a table with one of the column as INTERVAL TO SECOND datatype. Though there were no issues in inserting same dataset. Also one thing I have noticed is the data values are sometime 0 for this column but it is a normal behavior. In entity model this column is mapped to "Time" and in c# it is mapped to "TimeSpan". The version of Devart.data.Oracle is 7.2.114.0

datatype for this column in oracle = INTERVAL DAY(9) TO SECOND(7) and is Nullable

A Sample data would like this:

ID KPI_DEFINITION_ID TIMESTAMP FLOAT_VALUE UNIT_ID IDENTIFIER_1 IDENTIFIER_2 IDENTIFIER_3 DATE_TIME_VALUE INTERVAL_VALUE INTEGER_VALUE STRING_VALUE IS_STRING_NULL BOOL_VALUE
D0C0DB2B3C0DB243B59DC605A75824C9 833C3FE482A3DC4BA8C423273DAD1472 10/1/2013 4:00:00 PM (null) 5 Robot ULR1 Automatic (null) +000000000 00:42:15.0000000 (null) (null) (null) (null)


Thanks in advance

We cannot reproduce the problem with the latest (7.9.333) build of dotConnect for Oracle. Please upgrade to 7.9.333. If this doesn't help, send us a small test project.

If you do not have access to the licensed 7.9.333, you can check the functionality with the trial version.
