Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMzJlYzM0NTQ3... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-15463?atlOrigin=eyJpIjoiMzJlYz... ) HHH-15463 ( https://hibernate.atlassian.net/browse/HHH-15463?atlOrigin=eyJpIjoiMzJlYz... ) Adjust varchar/varbinary JdbcType based on size and also when explicitly specified ( https://hibernate.atlassian.net/browse/HHH-15463?atlOrigin=eyJpIjoiMzJlYz... ) Issue Type: Bug Assignee: Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) Components: hibernate-core Created: 25/Aug/2022 00:29 AM Fix Versions: 6.1.3 Priority: Major Reporter: Christian Beikov ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=557058%... ) We currently emit DDL types e.g. clob / blob}}when the size/length exceeds a certain value, but the {{JdbcType still is varchar / varbinary , which causes issues on certain databases where the JDBC driver does not support setString / setBytes for clob / blob , so we should adjust the types based on size also. After doing so, we could actually stop using clob / blob}}as biggest types for {{varchar / varbinary. It might be interesting to add new SqlTypes codes e.g. MATERIALIZED_CLOB and MATERIALIZED_BLOB for which we register JdbcType}}that bind through {{setString / setBytes. We would control this based on knowledge about whether the driver supports this through e.g. Dialect#supportsMaterializedLobAccess ( https://hibernate.atlassian.net/browse/HHH-15463#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-15463#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
