Flash Vayne ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) *updated* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiZDdhNjdlZjJj... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16436?atlOrigin=eyJpIjoiZDdhNj... ) HHH-16436 ( https://hibernate.atlassian.net/browse/HHH-16436?atlOrigin=eyJpIjoiZDdhNj... ) Hibernate 6 - Numeric Overflow Exception when retrieving the Meta-data for sequences from Oracle Database ( https://hibernate.atlassian.net/browse/HHH-16436?atlOrigin=eyJpIjoiZDdhNj... ) Change By: Flash Vayne ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=712020%... ) When I upgrade Hibernate from 5 to 6, Numeric Overflow Exception occurs. *Database Column:* NUMBER(10,0) *Column data:* '3876543210' * SQL: * !p1.png|width=449,height=68! * Exception: * !p2.png|width=1367,height=145! I found that the org.hibernate.OracleDialect always was set to default Dialect select Integer as JdbcType when precision = 10. If I change org.hibernate.OracleDialect to org.hibernate.MariaDBDialect, it works. I think there is a bug in org.hibernate.OracleDialect, but I can’t change it to older OracleDialect like Oracle10gDialect due to the reason in below alert ! p3 image-20230406-040731.png|width= 790 832 ,height= 50 437 ! Also I try all the hibernate 6.x version Actually '3876543210' is not a Integer data but can be saved in column NUMER(10 , neither works 0). So I think it’s bug, can you please help check it?
