[hibernate-issues] [Hibernate-JIRA] Reopened: (HBX-700) Custom type mapping is not possible when reverse-engineering Oracle TIMESTAMP(3) types

Custom type mapping is not possible when reverse-engineering Oracle TIMESTAMP(3) types -------------------------------------------------------------------------------------- Key: HBX-700 URL: http://opensource.atlassian.com/projects/hibernate/browse/HBX-700 Project: Hibernate Tools Issue Type: Bug Components: reverse-engineer Environment: 3.2 svn, Oracle 10g, Oracle JDBC Driver version - "10.2.0.1.0" Reporter: Genandiy Donchyts Attachments: hbm2java.cfg.xml, schema.sql, Test.hbm.xml Original Estimate: 1 hour Remaining Estimate: 1 hour When reverse-engineering Oracle database containint column with TIMESTAMP(3) type it is not recognized as a TIMESTAMP and "serializable" type is used instead of timestamp. This happens because of the bug in Oracle JDBC driver since it returns OTHER (1111) instead of TIMESTAMP(93). When type-mapping is provided in the form: <type-mapping> <sql-type jdbc-type="TIMESTAMP(3)" hibernate-type="timestamp" /> </type-mapping> ... it is not used because hibernate can't find TIMESTAMP(3) JDBC data type. JDBCReader.java, processBasicColumns(Table table, ProgressListener progress): ... //TODO: column.setSqlType(sqlTypeName); //this does not work 'cos the precision/scale/length are not retured in TYPE_NAME //column.setSqlType(sqlTypeName); ... it would be nice to have this sqlTypeName set to Column and used during comparison with <type-mapping>, then mapping from "TIMESTAMP(3)" to "timestamp" would work. Currently only 1111 ("OTHER") is passed to Column and as result column does not know anything about "TIMESTAMP(3)" ----- To reproduce an issue try to create simple Oracle database with one table: create table test(id TIMESTAMP(3)); and run reverse-engineering task over it. ------ HACK: custom handling of TIMESTAMP(*) types: Modify JDBCReader.java: private void processBasicColumns(Table table, ProgressListener progress) { // get the columns ... String sqlTypeName = (String) columnRs.get("TYPE_NAME"); String columnName = (String) columnRs.get("COLUMN_NAME"); // HACK: custom handling of TIMESTAMP(*) if(sqlTypeName.startsWith("TIMESTAMP")) { sqlType = java.sql.Types.TIMESTAMP; } ...
