I want to update a parent table and simultaneously save data in child table in a single custom query in hibernate.
This is my serviceimplementation.
public int updateTimeTable(Map<String, Object> timeTable) {
int rows = timeTableDao.updateTimeTable(timeTable);
if(rows>2) {
rows = temptimeTableDao.updateTempTimeTable(timeTable);
}
return rows;
}
This are the query files(save customQuery):
public int updateTempTimeTable(Map<String, Object> map) {
Query query = customQuery("Insert into temp_time_table(employee_id,duration_till,duration_from,timetable_id)"
+ " values(:employeeId, :durationStart,:durationEnd,:timetableId)");
query.setLong("employeeId", Long.parseLong(map.get("employeeId").toString()));
query.setString("durationStart", map.get("durationStart").toString());
query.setString("durationEnd", map.get("durationEnd").toString());
query.setLong("timetableId", Long.parseLong(map.get("timetableId").toString()));
return query.executeUpdate();
}
updateTimeTable query:
public int updateTimeTable(Map<String, Object> map) {
if (map.isEmpty() && !map.containsKey("id"))
return 0;
String hql = "update TimeTable set ";
int count = 0;
String status = null;
if (map.containsKey("status") && map.get("status") != null) {
hql += "status = :status";
status = map.get("status").toString();
count++;
}
if (count == 0) {
return 0;
}
hql += " where id = " + map.get("id");
Query query = update(hql);
if (status != null) {
query.setString("status", status);
}
return query.executeUpdate();
}

I have some Java code that runs an SQL query like this:
SELECT DISTINCT ven.enterprise_network_id, st.*
FROM studies st
inner join v_enterprise_network_members ven on st.ib_id = my_ib_id
WHERE ven.ib_id=:IB_ID
AND (st.myvrn_expiration_date IS NULL OR st.myvrn_expiration_Date >= sysdate)
ORDER BY st.study_date DESC
I understand everything except I don't understand what st.ib_id=my_ib_id. What does it mean? This is the whole method just in case if it helps:
public List<Study> searchRepository(StudySearchCriteria criteria, boolean isEnterpriseNetwork,
boolean isExactNameMatch) {
String selectForNone = null;
String studyStatus = null;
studyStatus = verifyStudyStatus(criteria, studyStatus, isEnterpriseNetwork);
if (criteria.contains(SearchField.STUDY_STATUS) && StringUtils.isBlank(studyStatus)) {
return new ArrayList<>();
}
if (StringUtils.isNotBlank(studyStatus) && studyStatus.contains(StudyPacsState.State.NONE.toString())) {
selectForNone = "DISTINCT {st.*}, st.study_date as stdate FROM studies st";
}
StringBuffer select = new StringBuffer(512);
StringBuffer where = new StringBuffer(512);
StringBuffer orderBy = new StringBuffer(selectForNone != null ? "" : " ORDER BY st.study_date DESC ");
select.append("SELECT ");

select.append(queryHint);
}
if (!isEnterpriseNetwork) {

/////////////////////////////////////
where.append(" WHERE ven.ib_id=:IB_ID AND ").append(myVrnSql);
}
StringBuilder queryForNone = selectForNone != null ? new StringBuilder(" UNION ") : new StringBuilder(" ");
createStudyStatusQuery(criteria, isExactNameMatch, studyStatus, where, queryForNone, false);
buildStudyQuery(criteria, select, where, orderBy, isEnterpriseNetwork, isExactNameMatch, true, false);

for (Object n : returned) {

result.add(st);
}
}
}
else {

}
}
else {

if (returned != null) {
result = new ArrayList<Study>();
for (Object n : returned) {

}
}
}
logger.debug(" returned " + (result == null ? 0 : result.size()));

st.ib_id=my_ib_id is the join condition - it defines the relationship between the two tables you are joining in the query. Presumably, my_ib_id is a column in one of those tables.
In the below code I am fetching the objects from the hive and passing the tbl_guid to fetch the matches in Mysql and Map will be returned as contains Map<tbl_guid ,uniqueseq>, then the on the based of tbl_guid as key already present the map dRListMap value List<DeletedRecord> DeletedRecord object property tbl_guid will be updated with fetched the uniqueseq fetched from the mysql.
Why am I replacing the tbl_guid with uniqueSeq fetching from the mysql because the on the based with small no corresponding to every tbl_guid which will stored in the HBase later of this, that part of code is not required herein discussion so I haven't posted? I would like to know where is enhancement is required current code.

I need to fetch data from multiple tables and export into excel sheet for each table. I don't want to use the getXXX() method as there are large number of columns and I don’t know the data type of each column. I need to fetch an entire row and store in the result in List.
I fetched each column using getObject() and also the class type using MetaData.getColumnClassName().
For example
Object val = resultSet.getObject(i);
I try to cast this val to its actual type using getColumnClassName() but it gives me an error while casting.
Can anyone please help me.
public class Row {
public Map<Object, Class> row;
public static Map<String, Class> TYPE;
static {
TYPE = new HashMap<String, Class>();
TYPE.put("INTEGER", Integer.class);
TYPE.put("NUMERIC", BigDecimal.class);
TYPE.put("DOUBLE", Double.class);
TYPE.put("VARCHAR2", String.class);
}
public Row() {
row = new HashMap<Object, Class>();
}
public <t> void add(t data) {
row.put(data, data.getClass());
}
public void add(Object data, String sqlType) {
add((Row.TYPE.get(sqlType)) data);
}
public static void formTable(ResultSet rs, List<Row> table) throws SQLException {
if(rs == null)
return;
ResultSetMetaData rsmd = rs.getMetaData();
int colCt = rsmd.getColumnCount();
while(rs.next()) {
Row row = new Row();
for(int i = 0; i < colCt; i++) {
row.add(rs.getObject(i), rsmd.getColumnTypeName(i));
}
table.add(row);
}
}
public static void main(String[] args) {
}
}
Try this code:
Connection connection = DriverManager.getConnection("URL", "USERNAME", "PASSWORD");
PreparedStatement statement = connection.prepareStatement("select * from table");
ResultSet resultSet = statement.executeQuery();
if (resultSet != null) {
while (resultSet.next()) {
ResultSetMetaData resultSetMetaData = resultSet.getMetaData();
for (int i = 1; i <= resultSetMetaData.getColumnCount(); i++) {
int type = resultSetMetaData.getColumnType(i);
if (type == Types.VARCHAR || type == Types.CHAR) {
System.out.println(resultSet.getString(i));
} else {
System.out.println(resultSet.getLong(i));
}
}
System.out.println("-----------");
}
}
You should extend it with other datatypes.
Step 1: get the metadata
ResultSetMetaData rsmd;
rsmd = rs.getMetaData();
int numColumns = rsmd.getColumnCount();
int[] columnsType = new int[numColumns + 1];
columnsType[0] = 0;
for (int i = 1; i <= numColumns; i++)
columnsType[i] = rsmd.getColumnType(i);
Step 2: fetch a row at a time from the result set and check the data type
String s;
Object o;
while (rs.next()) {
for (int i = 1; i <= numColumns; i++) {
if (columnsType[i] == java.sql.Types.NUMERIC || columnsType[i] == java.sql.Types.CHAR || columnsType[i] == java.sql.Types.VARCHAR) {
s = rs.getString(i);
} else if (columnsType[i] == java.sql.Types.NVARCHAR) {
s = rs.getNString(i);
} else if (columnsType[i] == java.sql.Types.BOOLEAN) {
// TODO
} else if (columnsType[i] == java.sql.Types.FLOAT || columnsType[i] == java.sql.Types.DOUBLE) {
// TODO
} else if (columnsType[i] == java.sql.Types.TINYINT || columnsType[i] == java.sql.Types.SMALLINT || columnsType[i] == java.sql.Types.INTEGER || columnsType[i] == java.sql.Types.BIGINT) {
// TODO
} else if (columnsType[i] == java.sql.Types.DATE || columnsType[i] == java.sql.Types.TIMESTAMP) {
// TODO
} else {
o = rs.getObject(i);
}
}
}
Step 3: fill the blanks and add the exception handling
Step 4: write to Excel (inside the loop)
