I need to do a select query against a mysql db in my java project

Hey guys!
I hope you can help me! I have a column "date" in my table of my MySQL DataBase. Well, when I prepare my statement in my java program, I can't compare a date to get all the rows where the date is the one that I'm trying to compare.
I'm trying to do something like this:
ResultSet rs = statement.executeQuery("select * from table where datecolumn=' "+ new java.sql.date(mydate.getTime()) + ' ");
But I have not been succesful yet. Can anyone, please, help me? How do I write the select if I have a variable of the kind java.util.Date and I want to compare it with the one in my DB?
Cheers!!!!

If there are too many fields to have pre-generated SQL for every possible subset, build the query at runtime. Here's some code. The array dates holds null for date fields that shouldn't be used to filter the data.
import java.sql.*;
public class Example {
    String[] dateColumns = {
        "date1",
        "date2",
        "date3",
    void f(Connection c, Date[] dates) throws SQLException {
        StringBuilder b = new StringBuilder("SELECT * FROM tableX WHERE 0=0 ");
        for(int i=0; i<dates.length; ++i) {
            if (dates[i] != null) {
                b.append("AND ").append(dateColumns).append(" = ? ");
String SQL = b.toString();
System.out.println("SQL = " + SQL);
PreparedStatement ps = c.prepareStatement(SQL);
for(int i=0, offset=1; i<dates.length; ++i) {
if (dates[i] != null) {
ps.setDate(offset, dates[i]);
offset++;
//use ps
}There's nothing tricky going on, the code just generates the obvious SQL.

I need help with a SELECT query - help!

Hello, I need help with a select statement.
I have a table with 2 fields as shown below
Name | Type
John | 1
John | 2
John | 3
Paul | 1
Paul | 2
Paul | 3
Mark | 1
Mark | 2
I need a query that returns everything where the name has type 1 or 2 but not type 3. So in the example above the qery should bring back all the "Mark" records.
Thanks,
Ian

Or, if the types are sequential from 1 upwards you could simply do:-
SQL> create table t as
2 select 'John' as name, 1 as type from dual union
3 select 'John',2 from dual union
4 select 'John',3 from dual union
5 select 'Paul',1 from dual union
6 select 'Paul',2 from dual union
7 select 'Paul',3 from dual union
8 select 'Paul',4 from dual union
9 select 'Mark',1 from dual union
10 select 'Mark',2 from dual;
Table created.
SQL> select name
2 from t
3 group by name
4 having count(*) <= 2;
NAME
Mark
SQL>Or another alternative if they aren't sequential:
SQL> ed
Wrote file afiedt.buf
1 select name from (
2    select name, max(type) t
3    from t
4    group by name
5    )
6* where t < 3
SQL> /
NAME
Mark

Please suggest me on using ':' bind character in DB adapter Select Query SOA11g.
Can someone help me on this please?
Thanks,
Hari

Hi,
Could you please make sure your binding style(Oracle Positional,Oracle named..etc) of the Seeded VO and Custom Vo are same.
This is the option you will get when you are extending your vo. So make sure that both are same.
You can refer the below link too
VO extension leads to "Invalid column index" exception

Need help for SQL SELECT query to fetch XML records from Oracle tables having CLOB field

Hello,
I have a scenario wherein i need to fetch records from several oracle tables having CLOB fields(which is holding XML) and then merge them logically to form a hierarchy XML. All these tables are related with PK-FK relationship. This XML hierarchy is having 'OP' as top-most root node and ‘DE’ as it’s bottom-most node with One-To-Many relationship. Hence, Each OP can have multiple GM, Each GM can have multiple DM and so on.
Table structures are mentioned below:
OP:
Name                             Null                    Type
OP_NBR                    NOT NULL      NUMBER(4)    (Primary Key)
OP_DESC                                        VARCHAR2(50)
OP_PAYLOD_XML                           CLOB
GM:

I am using above SQL select statement for fetching the XML records and this gives me all related xmls for each entity in a single record(OP, GM, DM. DE). Output of this SQL query is as below:
Current O/P:

          <OP_PAYLOD_XML1>

     <Record2>
          <OP_PAYLOD_XML2>
          <GM_PAYLOD_XML2>

          <DM_PAYLOD_XMLN>

          <DE_PAYLOD_XMLN'>
     </Record>
<resultSet>
Appreciate your help in this regard!

Hi,
A few questions :
How's your first query supposed to give you an XML output like you show ?
Is there something you're not telling us?
What's the content of, for example, <OP_PAYLOD_XML1> ?
I don't think it's a good idea to embed the node level in the tag name, it would make much sense to expose that as an attribute.
What's the db version BTW?

Running a Select query against multiple sql servers using SSIS script task.

Hi Guys,
I need to fetch data from multiple sql servers using SSIS scirpt task inside a foreach container.
is there anyway i can build dynamic sql connections using ssis variables inside SSIS script task in each loop
Please guide me or refer any blogs so that i will try..
Thanks in advance.

Your only options is using .net code, then it will be no different than using a console app in a loop.
using (SqlConnection connection = new SqlConnection(connectionString))
connection.Open();
Console.WriteLine("ServerVersion: {0}", connection.ServerVersion);
Console.WriteLine("State: {0}", connection.State);
and so forth for each connection string
the connection string would come from the ForEach loop

What does it mean when the usecounts of Parse Tree for a view is incrementing when a select query is issued against the view?

I'm using SQL Server 2008 R2 (10.50.4033) and I'm troubleshooting an issue that a select query against a specific view is taking more than 30 seconds consistently.   The issue just starts happening this week and there is no mass changes in data.
The problem only occur if the query is issued from an IIS application but not from SSMS. One thing I noticed is that sys.dm_exec_cached_plans is returning 2 Parse Tree rows for the view - one created when the select query is issued
1st time from the IIS application and another one created when the same select query is issued 1st time from SSMS.   The usecounts of the Parse Tree row for the view (the IIS one) is increasing whenever the select query is issued.  The
usecounts of the Parse Tree row for the view (the SSMS one) does not increase when the select query is issued again.
There seems to be a correlation between the slowness of the query and the increasing of the usecounts of the Parse Tree row for the view.
I don't know why there is 2 Parse Tree rows for the view. There is also 2 Compiled Plan rows for the select query.
What does the Parse Tree row mean especially the usecounts column?

>> The issue just starts happening this week and there is no mass changes in data.
There might be a mass changes in the execution plan for several reason without mass changes in data
If you have the old version and a way to check the old execution plan, and compare to the new one, that this should be your starting point. In most cases you don't have this option and we need to monitor from scratch.
>> The problem only occur if the query is issued from an IIS application but not from SSMS.
This mean that we know exactly what is the different and you can compare both execution plan. once you do it, you will find that they are no the same. But this is very common issue and we can know that it is a result of different SETting while connecting
from different application. SSMS is an external app like any app that you develop in Visual studio but the SSMS dose not use the Dot.Net default options.
Please check this link, to find the full explanation and solutions:
http://www.sommarskog.se/query-plan-mysteries.html
Take a look at sys.dm_exec_sessions for your ASP.Net application and for your SSMS session.
If you need more specific help, then we need more information and less stories :-)
We need to see the DDL+DML+Query and both execution plans
>> What does the Parse Tree row mean
I am not sure what you mean but the parse tree represents the logical steps necessary to execute the query that has been requested. you can check this tutorial about the execution plan: https://www.simple-talk.com/sql/performance/execution-plan-basics/ or
this one: http://www.developer.com/db/understanding-a-sql-server-query-execution-plan.html

Need help in writing a select query to pull required data from 3 tables.

Hi,
I have three tables EmpIDs,EmpRoles and LatestRoles. I need to write a select Query to get roles of all employees present in EmpIDs table by referring EmpRoles and LatestRoles.
The condition is first look into table EmpRoles and if it has more than one entry for a particular Employee ID than only need to get the Role from LatestRoles other wise consider
the role from EmpRoles .
Sample Script:
Create Table #EmpIDs
(EmplID int )
Create Table #EmpRoles
(EMPID int,Designation varchar(50))
Create Table #LatestRoles
EmpID int,
Designation varchar(50)
Insert into #EmpIDs values (1),(2),(3)
Insert into #EmpRoles values (1,'Role1'),(2,'Role1'),(2,'Role2'),(3,'Role1')
Insert into #LatestRoles values (2,'Role2')
Employee ID 2 is having two roles defined in EmpRoles so for EmpID 2 need to fetch Role from LatestRoles table and for
remaining ID's need to fetch from EmpRoles .
My Final Output of select query should be like below.
EmpID Role
1 Role1
2 Role2
3 Role1
Please help.
Mohan

Mohan,
Can you check if this answers your requirement:
Create Table #EmpIDs
(EmplID int )
Create Table #EmpRoles
(EMPID int,Designation varchar(50))
Create Table #LatestRoles
EmpID int,
Designation varchar(50)
Insert into #EmpIDs values (1)
Insert into #EmpIDs values (2)
Insert into #EmpIDs values (3)
Insert into #EmpRoles values (1,'Role1')
Insert into #EmpRoles values (2,'Role2')
Insert into #EmpRoles values (2,'Role1')
Insert into #EmpRoles values (3,'Role1')
Insert into #LatestRoles values (2,'Role2')
--Method 1
select e.EmplID,MIN(ISNULL(l.Designation,r.Designation)) as Designation
from #empids e
left join #emproles r on e.emplID=r.EmpID
left join #latestRoles l on e.emplID=l.EmpID
group by e.EmplID
--Method 2
;with cte
as
select distinct e.EmplID,r.Designation,count(*) over(partition by e.emplID) cnt
from #empids e
left join #emproles r on e.emplID=r.EmpID
select emplID,Designation
from cte
where cnt=1
UNION ALL
select a.EmplID,l.Designation
from
(select distinct EmplID from cte where cnt>1) a
join #Latestroles l on a.EmplID=l.EmpID
order by emplID
Thanks,
Jay

you have a choice between logging into each user & running the SQL or you can log into each user & run the SQL.

How to select Subpartition name in a Select query?

Hi,
I have a table that is partitioned on date range and subpartitioned based on and ID list. Lets assume the table name is something like: MY_TABLE
The partition name would look like: P_20110126160527
The subpartition list is as follows: GB, IN, AU, US etc. The sub partition name for GB would look like
P_20110126160527_GB
I need to run a select query to fetch data from MY_TABLE along with Sub partition name. The result set needs to look like:
Name|Location|SubPartition
Sam|UK|P_20110126160527_GB
Tom|UK|P_20110126160527_GB
Dave|AU|P_20110126160527_AU
The data available in ALL_TAB_SUBPARTITIONS and USER_TAB_SUBPARTITIONS can't be used just because the only join condition available is the TABLE Name but we would also have to join on SUBPARTITION KEY. I am not sure how to achieve this.
Does anyone here have a clue?

In a pinch, you could do something like this.
select col1, col2, col3, 'PARTITION_1' from your_table where key_col in <values for partition_1>
union all
select col1, col2, col3, 'PARTITION_2' from your_table where key_col in <values for partition_2>
union all
select col1, col2, col3, 'PARTITION_3' from your_table where key_col in <values for partition_3>
union all
...Or better yet:
select col1, col2, col3, case when key_col = 'x' then 'PARTITION_1'
                              when key_col = 'y' then 'PARTITION_2'
                              when key_col = 'z' then 'PARTITION_3'
                         end
from ...Of course, none of these would be "dynamic".

Dynamic Select Query including Dynamic Tables with For all Entries

Hello everyone,
I need to create a select query which involves using of Dynamic Tables.
Suppose I have a dynamic table <d1> which consist of let say 10 records.
Now i need to make a select query putting data into another dynamic table <d2>
CONCATENATE keyfield '=' '<d1>' INTO g_condition SEPARATED BY space.
CONCATENATE g_condition '-' keyfield INTO g_condition.
SELECT * FROM (wa_all_tables-name) INTO CORRESPONDING FIELDS OF TABLE <d1>
        FOR ALL ENTRIES IN <d1>
WHERE (g_condition).
But it is giving dump.
Please help me on this....

    A condition specified at runtime has an unexpected format.
What happened?
    Error in the ABAP Application Program
    The current ABAP program "ZNG_CUSTOMWRITE" had to be terminated because it has
    come across a statement that unfortunately cannot be executed.
Error analysis
    An exception occurred that is explained in detail below.
    The exception, which is assigned to class 'CX_SY_DYNAMIC_OSQL_SEMANTICS', was

    Since the caller of the procedure could not have anticipated that the

Select query as input in PARAMETERS.

Hi Expert,
We need to give input as Select query. Like below are examples.
1) Select * from ekko into table it_data where bukrs = 3000. or
2) select fld1 fld2 fld3 from tablename into it_data up to 10 rows where fld4 = XXXXX.
We want to pass only such query as input and want result according to them. User can put any table name, can chose any table fields, also he can use inner join group by statements also.
Remember we want to pass only select query by user in PARAMETERS as below.
parameters: option type string.
In Option we need to wright that select query.
Please provide some coding samples.
Thanks And Regards
Ranjeet Singh

I think you should stay in strong oposition to customer requirement like that. This is like dynamic SQL, which if not authenticated properly would give a user to insight very sensitive data (like salaries, payments etc). Actually in SAP there is some sophisticated tool like that, called SAP Query. The user who have proper authorization can create any query he likes with no ABAP knowledge at all. I would really stick to what SAP provides by standard.
If your custmer, is however persistent in his decision (he pays, he decides), you should developed such tool with dynamic program generation, which as mentioned above can be achieved with [GENERATE SUBROUTINE POOL|http://help.sap.com/abapdocu_70/en/ABAPGENERATE_SHORTREF.htm]. RTTS will not help here as they can be used only for dynamic structure/tables generation, not queries themselves.

from one set of ident one record should come in this way so many set of idents will be there.
My question is how to form the select query

Hello Chandra,
Your solution lies in the concept of Control-Break Statements.
AT NEW..
AT END OF
AT LAST, etc.
DATA:
BEGIN OF fs_table,
    zident TYPE char20,
    date   TYPE sy-datum,
    time TYPE sy-uzeit,
    status TYPE C,
END OF fs_table.
DATA:
        t_table LIKE
STANDARD TABLE
              of   fs_table.
" Populate the data in Internal Table.
" While displaying data.
LOOP AT t_table INTO fs_table.
AT NEW status.
     WRITE:/ fs_table-status.
ENDAT.
     WRITE:/ fs_table-zident,
                  fs_table-date,
                  fs_table-time.
ENDLOOP.
You can also use ON CHANGE OF fs_table-status, instead of AT NEW, if you get ***//* for date and time.
With this, status will be displayed once and remaining will following under it.
If you want everything to be displayed on change of each new field, apply that to every field,
eg:
AT NEW zident.
   WRITE:/ fs_table-zident.
ENDAT.
AT NEW date.
   WRITE: fs_table-date.
ENDAT.
.. so on and so forth.
This is just a test-case, try using the control break statements.
Hope it helps you.

Wildcard in select query

Hi,
I am having one requirement,
In my report i need to give cost centre in
selection screen(select-options).
Based on that i need to fetch WOGBTR from COEP table.
eg : cost center i need to give like this
imagine
select-options : s_kostl for csks-kostl.
now in s_kostl-low if i give value klnnn12345* and
in s_kostl-high if i give value klnnn12350*
now based on these input i need to write a select query in
the program to fetch the records from COEP table.
can any body please let me know how to code where condition
in the select query in this case...
Thanks and regards,
vasu

Hi Vasu,
you will reach information of the field WOGBTR in the table COEP over the criteria costcenter (KOSTL).
The costcenter isn't an attribute of table COEP, but of table CSKS.
The link between CSKS and COEP is the attribute KOKRS.
So you have to do the following steps:
1. Get the values of KOKRS from table CSKS over your select-options s_kostl (... where kostl in s_kostl)
select * into table <itab_csks> from csks
where kostl in s_skostl.
2. Build a new rangetable for KOKRS
loop at <itab_csks> into ls_csks.
lr_kokrs-sign = 'I'.
lr_kokrs-option = 'EQ'.
lr_kokrs-low = ls_csks-kokrs.
collect lr_kokrs into lrt_kokrs.
endloop.
3. Start a new query for the table COEP with your new tangetable for KOKRS
Select * into table <itab_coep> from coep
where kokrs into lrt_kokrs.
now you have the information you needed.
