acceptField

protected boolean acceptField(java.lang.reflect.Field curr)

in ClassSchemaInfo Create a diff between current schema and in db schema.

requires:

• create schema objects from class
• load schema objects from db
• compare schema objects
• generate diff sql

private void applySQL(ClassSchemaInfo info, String sql) throws IOException { File outFile = File.createTempFile(getForClass().getSimpleName() + "." + info.version + ".to." + version, ".sql"); Util.copy(new StringReader(sql), new FileWriter(outFile)); System.out.println("Generated sql for: " + forClass.getName() + " in " + outFile.getAbsolutePath()); try { File databaseFile = JDBCRepository.getDatabaseFile(); log.info("Applying sql to database: " + databaseFile.getAbsolutePath()); // NOTE could do remote databases // NOTE should be delegate. should handle mysql, etc ISQL isql = new ISQL(databaseFile.getAbsolutePath(), "localhost", "" + JDBCRepository.CFG_USER.getValue(), "" + JDBCRepository.CFG_PASSWORD.getValue()); isql.exec(outFile); log.info("Integrated schema into database for: " + getForClass().getName() + " from:" + outFile.getAbsolutePath()); outFile.delete(); return; } catch (ObjectRepositoryException e1) { log.warn("Database must be local"); } catch (InterruptedException e1) { log.warn("Error running isql", e1); } catch (IOException e1) { log.warn("Error running isql", e1); } log.info("Failed sql is in: " + outFile.getAbsolutePath()); }
