OracleRDBMSMetadataBuilder support for keyColumn path field - to support Mongo collection creation #16
Comments
Additionally , keyColumnAssignmentMethod("EMBEDDED_OID") needs support added. final OracleDocument metadata = cl.createMetadataBuilder().contentColumnName("DATA").keyColumnName("ID").keyColumnType("VARCHAR2").keyColumnMaxLength(255).keyColumnAssignmentMethod("EMBEDDED_OID").versionColumnName("VERSION").versionColumnMethod("UUID").lastModifiedColumnName("LAST_MODIFIED").creationTimeColumnName("CREATED_ON").schemaName(targetUser).tableName("COMPANY").build(); Currently the following exception is seen ... OracleException occurred : Invalid argument value "EMBEDDED_OID". |
createCollection() - OracleException occurred : Invalid argument value "EMBEDDED_OID". |
Looks like even PL/SQL doesn't work .. and the only hope is just using ORDS http request directly ... createCollection() - SQLException occurred : ORA-40842: unsupported value EMBEDDED_OID in the metadata for the field assignmentMethod java.sql.SQLException: ORA-40842: unsupported value EMBEDDED_OID in the metadata for the field assignmentMethod
Caused by: Error : 40842, Position : 0, Sql = DECLARE

Right, currently we only support EMBEDDED_OID thru Mongo API (as documented here). But we're working on adding it in the SODA drivers. For SODA Java, it's currently planned for the next release. May I ask if there's some urgency on this for you, so that we prioritize accordingly? Please feel free to email us directly with details if that's easier. My email is: maxim dot orgiyan at oracle dot com (remove the spaces, change "at" to "@", and change "dot" to "."). Thank you! |
Using a SODA REST client, I can create the mongo compatible collection. That collection though cannot be read using
It will give the error ... oracle.soda.OracleException: Invalid argument value "EMBEDDED_OID". |
Mongo compatible collection creation on 19c using ords PUT against /ords/admin/soda/latest/< collectionname > may look similar to ...
{"contentColumn":{"name":"DATA"},"keyColumn":{"name":"ID","sqlType":"VARCHAR2","maxLength":255,"assignmentMethod":"EMBEDDED_OID","path":"_id"},"versionColumn":{"name":"VERSION","method":"UUID"},"lastModifiedColumn":{"name":"LAST_MODIFIED"},"creationTimeColumn":{"name":"CREATED_ON"}}
OracleRDBMSMetadataBuilder doesn't appear to support that path parameter override.
