URL: https://github.com/apache/kylin/pull/1490#issuecomment-735626681
From my side, there is some difference from old implementation, OLD impl
will comare generated SQL with original one`Assert.assertEquals(expectedSQL,
optimizedSQL);`. Please consider implement it later.
```
protected void execAndCompPlan(String queryFolder, String[]
exclusiveQuerys, boolean needSort,
ICompareQueryTranslator translator) throws Exception {
logger.info("---------- test folder: " + new
File(queryFolder).getAbsolutePath());
Set<String> exclusiveSet = buildExclusiveSet(exclusiveQuerys);
List<File> sqlFiles = getFilesFromFolder(new File(queryFolder),
".sql");
for (File sqlFile : sqlFiles) {
String queryName = StringUtils.split(sqlFile.getName(), '.')[0];
if (exclusiveSet.contains(queryName)) {
continue;
}
String sql1 = getTextFromFile(sqlFile);
String sql2 = translator.transform(sqlFile);
// execute Kylin
logger.info("Query Result from Kylin - " + queryName + " (" +
queryFolder + ")");
IDatabaseConnection kylinConn = new
DatabaseConnection(cubeConnection);
ITable kylinTable = executeQuery(kylinConn, queryName, sql1,
needSort);
RelNode calcitePlan = (RelNode)
QueryContextFacade.current().getCalcitePlan();
if (calcitePlan == null)
throw new NullPointerException();
// execute H2
logger.info("Query Result from H2 - " + queryName);
long currentTime = System.currentTimeMillis();
ITable h2Table = executeQuery(newH2Connection(), queryName,
sql2, needSort);
logger.info("H2 spent " + (System.currentTimeMillis() -
currentTime) + " mili-seconds.");
try {
// compare the result
assertTableEquals(h2Table, kylinTable);
} catch (Throwable t) {
logger.info("execAndCompQuery failed on: " +
sqlFile.getAbsolutePath());
throw t;
}
RelToSqlConverter converter = new RelToSqlConverter(CALCITE);
SqlNode sqlNode = converter.visitChild(0,
calcitePlan.getInput(0)).asStatement();
String optimizedSQL = sqlNode.toSqlString(CALCITE).getSql();
String expectedSQL = Strings.join(Files.readLines(
new File(sqlFile.getParent(), sqlFile.getName() +
".expected"), Charset.forName("utf-8")), "\n");
Assert.assertEquals(expectedSQL, optimizedSQL);
compQueryCount++;
if (kylinTable.getRowCount() == 0) {
zeroResultQueries.add(sql1);
}
}
}
