I have a select Oracle SQL that I am hitting using jdbcTemplate.query method. This returns a bean of the values from the table. I am passing a dynamic value to the query that will be used in the WHERE clause. However, the SQL values for few values that i am passing. But when I pass the value as NA it won't work. Any suggestions on this or help me with what am i missing?
private static final String regionSearchSql = "SELECT PRFLID, PRFLNM, RGN_CD FROM %PREFIX%MER_PRFL WHERE RGN_CD = ?";
public List<SearchProfileBean> regionSearchProfile(SearchProfileRequest searchProfileRequest) throws DatabaseQueryException {
try {
return jdbcTemplate.query((QueryUtility.getQueryWithPrefix(regionSearchSql,prefix)), new SearchProfileRowMapper(), searchProfileRequest.getRegionName());
} catch (Exception e) {
throw new DatabaseQueryException(QueryUtility.getQueryWithPrefix(regionSearchSql, prefix), e);
}
}
If i pass 'EMEA', 'LAC', 'JAPA' in searchProfileRequest.getRegionName() - the SQL returns perfect results. But if I pass 'NA' in searchProfileRequest.getRegionName(), it gives empty results. But there are rows in the table for NA.

I am setting a breakpoint in mybatis source BaseExecutor's queryFromDatabase function in Intellij Idea, this code block look like this:
private <E> List<E> queryFromDatabase(MappedStatement ms, Object parameter, RowBounds rowBounds, ResultHandler resultHandler, CacheKey key, BoundSql boundSql) throws SQLException {
List<E> list;
localCache.putObject(key, EXECUTION_PLACEHOLDER);
try {
list = doQuery(ms, parameter, rowBounds, resultHandler, boundSql);
} finally {
localCache.removeObject(key);
}
localCache.putObject(key, list);
if (ms.getStatementType() == StatementType.CALLABLE) {
localOutputParameterCache.putObject(key, parameter);
}
return list;
}
but the boundSql content shows sql like this:
select * from article where channel_id in (?)
is it possible to get the execute sql in the trace? because the channel_id has more than 100 and the sql also contains other filter condition.
Hello I am writing a query to insert values in DB SQLite.
Firstly, I read from my records and searched for two values, for example, then I created a new table and inserted new values in.
My code snippet follows:
try
{
Class.forName("org.sqlite.JDBC");
Connection con=DriverManager.getConnection("jdbc:sqlite:tests.db");
con.setAutoCommit(false);
Statement st=con.createStatement();
st.executeUpdate("delete msearch");
ResultSet res=st.executeQuery("select * from newmobile_details");
Boolean rec=res.next();
if(!rec)
{
JOptionPane.showMessageDialog(null,"لايوجد سجلات");
}
else
{
do
{
String mid=res.getString(1);
String model=res.getString(2);
String name=res.getString(3);
int price=res.getInt(4);
String pcolor=res.getString(5);
String imei=res.getString(6);
java.sql.Date date=res.getDate(7);
String access=res.getString(8);
if(mname.equalsIgnoreCase(name))
{
PreparedStatement prp=con.prepareStatement("insert into msearch values(?,?,?,?,?,?,?,?)");
prp.setString(1,mid);
prp.setString(2,model);
prp.setString(3,name);
prp.setInt(4,price);
prp.setString(5,pcolor);
prp.setString(6,imei);
prp.setDate(7,date);
prp.setString(8,access);
prp.executeUpdate();
System.out.println("iam inside2");
rows++;
b=1;
jTextField2.setText("");
}
}while(res.next());
if(b==0)
{
JOptionPane.showMessageDialog(null,"لم يتم العثور على الموبايل ");
jTextField2.setText("");
}
}
con.commit();
con.close();
}
catch(Exception e)
{
JOptionPane.showMessageDialog(null,"The error is1:" +e);
}
I get only exception as below:
The error is1 :sql error or missing database in msearch syntax error
Larry makes a good point and looking at your code more carefully I believe the problem is with the statement
st.executeUpdate("delete msearch");
It seems to be saying you should be qualifying msearch with a database name.
This is the syntax for an insert statement
INSERT INTO TABLE_NAME (c1, c2, c3,...cN)
VALUES (v1, v2, v3,...vN);
You give a list of column names and a list of values.
You don't have the list of column names.
This can't work.
I run an insert statement using Apache DBUtils. However, I am not sure why I have to include ResultSetHandler for this case:
String theQuery = QueryGenerator.insertintoStats();
ResultSetHandler<Object> dummyHandler = new ResultSetHandler<Object>() {
#Override
public Object handle(ResultSet rs) throws SQLException
{
return null;
}
};
try
{
queryRunner.insert(connection, theQuery, dummyHandler, Constants.UUIDSTR.toString(), name, prevbackupTime,
curbackupTime, updStartTime, delStartTime, bkupType.toString(), rowCount);
}
catch (SQLException e)
{
LOGGER.info(theQuery.toString());
LOGGER.error("Caught exception!", e);
}
Similar's the case for insertbatch which does use ResultSetHandler. I have resorted to use batch call for batch queries. Can anyone explain why we would be needing resultset handler for insert?
From documentation https://commons.apache.org/proper/commons-dbutils/apidocs/:
public <T> T insert(String sql,
ResultSetHandler<T> rsh,
Object... params)
throws SQLException
rsh - The handler used to create the result object from the ResultSet
of auto-generated keys.
If you insert values in a table which generate id upon insertion, you can retrieve it back, for example see this answer how to do this manually : https://stackoverflow.com/a/1915197/947111
You need ResultSetHandler<T> rsh to iterate over ResultSet which returned with id's which has been created.
i use struts2 and hibernate jpa for my app and i have an error when traying using update query with hibernate
here is my code :
in my class dao
#Override
public void UpdateNoteEvaluation() {
try {
String hql="update Evaluation e " +
"SET e.Eval_NoteGlobal =: ( SELECT SUM( sv.SousEval_Note ) AS sum FROM sousevaluation sv )" +
"ORDER BY EVAL_ID DESC LIMIT 1 ";
Query q= session.createQuery(hql);
q.executeUpdate();
} catch (Exception e) {
transaction.rollback();
e.printStackTrace();
}
}
in my class Action :
public String saveOrUpdate(){
sousevaldao.UpdateNoteEvaluation();
System.out.println("update note ok ok");
return SUCCESS;
}
so here i can't make the update i get this error :
java.lang.IllegalArgumentException: node to traverse cannot be null!
at org.hibernate.hql.ast.util.NodeTraverser.traverseDepthFirst(NodeTraverser.java:55)
at org.hibernate.hql.ast.QueryTranslatorImpl.parse(QueryTranslatorImpl.java:277)
knowing i have test the update query im phpmyadmin it's work fine
If query has been tested to be working one via phpMyAdmin, it is quite clear that query is SQL query - not a HQL query. Also syntax of query seems to contain MySQL SQL dialect specific LIMIT clause.
Query for native SQL queries can be created via Session.createSQLQuery(String queryString) method:
String sql = ...
Query q = session.createSQLQuery(sql);
I was performing JDBC select query in my web service to return some values from my database. Part of this table is attached to this question. After performing following query:
SELECT * FROM uses WHERE uses_user_fk='22';
I receive only one row, but in database are two values that meet the query conditions, as you can see in attached picture. Can anyone tell me where I made a mistake. I’m using following JDBC instruction to execute the query
ResultSet tempResultSet = statement.executeQuery(query);
Bellow image of database table uses:
Below the compete method that query the database, argument query is the same as listed earlier “SELECT * FROM uses…”. I should add that the answer for that query is 4, I also try this query without using quotes (uses_user_fk=22) but the result was the same:
protected ArrayList<Integer> queryForIds(String query, String column) throws Exception {
ArrayList<Integer> ids = new ArrayList<>();
try {
Class.forName("com.mysql.jdbc.Driver");
connect = DriverManager
.getConnection(GeneralDatabaseConstants.DATABASE_CONNECTION_URL);
statement = connect.createStatement();
ResultSet tempResultSet = statement.executeQuery(query);
if (tempResultSet.next())
ids.add(new Integer(tempResultSet.getInt(column)));
} catch (Exception e) {
throw e;
} finally {
close();
}
return ids;
}
replace
if (tempResultSet.next())
with
while (tempResultSet.next())
