Possible to execute custom SQL query?

Is it possible to execute a custom SQL query and get back a collection of
objects with Kodo JDO? Query expression languages like JDOQL are all very
well (I actually think JDOQL is pretty messy), but sometimes when you've
got a complex query (and you know you're using a RDBMS) it is best
accomplished in a SQL statement. I see Kodo has extended JDOQL, which is
good, but developing custom extensions seems to be limited to implementing
kodo.jdbc.query.JDBCFilterListener where you can customise the where
clause. What I want to be able to do is to specify the entire SQL string.
I am looking into using Kodo JDO for my organisation, and being able to
use custom SQL is something i would expect (and something we can do with
our current O/R mapping product (TopLink)).

Alex

We absolutely agree. Take a look at the samples/customSQL example in the
Kodo distribution.

SolarMetric Inc.Hi Patrick,
I have downloaded kodo-jdo-3.0.0RC1 for windows for evaluation, but there
is no samples/customSQL directory.

Execute custom SQL query in OIM11g

Hi,
Can you please provide me some java code snippet to execute a custom sql query and also to get db connection to execute this query in OIM 11g. I am going to run this query in an adapter.
Thanks a lot for ur help.
Mike

Hey Mike,
Use the below sample code to get db connection and then to execute a query in OIM11g.
String query = "SELECT UD_ADUSER_EMAIL FROM UD_ADUSER WHERE upper(UD_ADUSER_UID) like '%TESTU%'";
Connection con = Platform.getOperationalDS().getConnection();
PreparedStatement preparedStatement = con.prepareStatement(query);
ResultSet resultSet = preparedStatement.executeQuery();
while(resultSet.next())
System.out.println("Output:"+resultSet.getString(1));
}

It is possible to execute a SQL query from OMBPlus?

We have some simple SQL scripts we'd like to be able to incorporate into our existing TCL scripts, instead of having to run them outside of OMBPlus in sqlplus. Is is possible to run a SQL SELECT query from OMBPlus and/or TCL? And get a result set back to iterate through?
Thanks,
Jim C.

You can execute SQLPlus from OMB or just get down and use JDBC to execute the SQL, see others posts on forum such as below;

How to operate multiple querys using DB Adapter and 'Execute Custom SQL'

I have a requirment that I need to create database adapter in your BPEL process with 'Execute Custom SQL' to operate multiple query in DB in one atomic
here are the details:
inbound request:
<ns1:Query_bpelProcessRequest>
<ns1:input>
<ns1:ItemDetail>
<ns1:ItemID>1123DDDS</ns1:ItemID>
</ns1:ItemDetail>
<ns1:ItemDetail>
<ns1:ItemID>1126EWWA</ns1:ItemID>
</ns1:ItemDetail>
<ns1:ItemDetail>
<ns1:ItemID>11208FSAA</ns1:ItemID>
</ns1:ItemDetail>
</ns1:input>
</ns1:Query_bpelProcessRequest>
I use for-each fuction in XSLT to mapping the all ItemID value:
<xsl:template match="/">
<xsl:for-each select="/tns:Query_bpelProcessRequest/tns:input/tns:ItemDetail">
<ns1:QueryFromDB_Input>
<ns1:ItemID>
<xsl:value-of select="tns:ItemID"/>
</ns1:ItemID>
</ns1:QueryFromDB_Input>
</xsl:for-each>
</xsl:template>
and in DB Adapter I use the 'Execute Custom SQL' to query the CONTENT value according the ItemID value:
select distinct CONTENT from agile.item where ITEM_NUMBER=’<ItemID>’
However, in the result, It only query the first item value for <ns1:ItemID>1123DDDS</ns1:ItemID>
<<QueryFromDB_InputVariable><part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="QueryFromDB_Input_msg">
<QueryFromDB_Input xmlns:ns1="http://xmlns.oracle.com/pcbpel/adapter/db/QueryFromDB" xmlns="http://xmlns.oracle.com/pcbpel/adapter/db/QueryFromDB">

</QueryFromDB_Input>
</part></QueryFromDB_InputVariable>

<ITEM_NUMBER>1123DDDS</ITEM_NUMBER>
<CONTENT >SJIFESSFFJ</CONTENT >
</QueryFromDB_Output>
</QueryFromDB_OutputCollection>
</part></QueryFromDB_OutputVariable>
the other two querys are not operated.
what can I do to operate multiple querys??
Thanks

Hi Rod,
I are using while loop and assign array inputvalue to the inputvarable of DBadapter now, but actually it doesn't work.

Can we implement the custom sql query in CR for joining the two tables

Hi All,
Is there anyway to implement the custom sql query in CR for joining the two tables?
My requirement here is I need to write sql logics for joining the two tables...
Thanks,
Gana

In the Database Expert, expand the Create New Connection folder and browse the subfolders to locate your data source.
Log on to your data source if necessary.
Under your data source, double-click the Add Command node.
In the Add Command to Report dialog box, enter an appropriate query/command for the data source you have opened.
For example:
SELECT
    Customer.`Customer ID`,
    Customer.`Customer Name`,
    Customer.`Last Year's Sales`,
    Customer.`Region`,
    Customer.`Country`,
    Orders.`Order Amount`,
    Orders.`Customer ID`,
    Orders.`Order Date`
FROM
    Customer Customer INNER JOIN Orders Orders ON
        Customer.`Customer ID` = Orders.`Customer ID`
WHERE
    (Customer.`Country` = 'USA' OR
    Customer.`Country` = 'Canada') AND
    Customer.`Last Year's Sales` < 10000.
ORDER BY
    Customer.`Country` ASC,
    Customer.`Region` ASC
Note: The use of double or single quotes (and other SQL syntax) is determined by the database driver used by your report. You must, however, manually add the quotes and other elements of the syntax as you create the command.
Optionally, you can create a parameter for your command by clicking Create and entering information in the Command Parameter dialog box.
For more information about creating parameters, see To create a parameter for a command object.
Click OK.
You are returned to the Report Designer. In the Field Explorer, under Database Fields, a Command table appears listing the database fields you specified.
Note:
To construct the virtual table from your Command, the command must be executed once. If the command has parameters, you will be prompted to enter values for each one.
By default, your command is called Command. You can change its alias by selecting it and pressing F2.

Looks like in production you have much more data than you do in your test environments.

What happens when you run this command inside SQLPlus?

How to execute a sql query in VO????

Hi every body.
Can you show me the way to execute a sql query in VO.
For example: I have a viewobject1, and I add a new method void execSQL() before the last '}' of the java file of viewobject1 like this:
public void execSQL() {
String strSql = "Select sysdate from dual";
I want to execute strSql query and return a Resultset, how can I perform ???
Thanks a lot.

The executeQuery method in ViewObjectImpl does not return a ResultSet.
ViewObjectImpl voImpl;
voImpl.setQuery(strSql);
voImpl.executeQuery();

Hi Niels,
As I'm sure you know, the conundrum is that Reports doesn't know how many total pages there will be in the report until it is all done formatting, which is too late for your needs. So, one classical solution to this problem is to run the report twice, storing the total number of pages in the database using a format trigger, and throwing away the output from the first run when you don't know the total number of pages.
Alternatively, you could define a report layout so that the number of pages in the output is completely predictable based upon, say, the number of rows in the main query. E.g., set a limit of one, two, ... rows per page, and then you'll know how many pages there will be simply because you can count the rows in a separate query.
Hope this helps...
regards,
Stewart

How to execute an SQL query present in a string inside an ABAP program?

hello,
How to execute an SQL query present in a string inside an ABAP program

Raut,
You can execute Native SQl statements.
Ex: To use a Native SQL statement, you must precede it with the EXEC SQL statement, and follow it with the ENDEXEC statement as follows:
EXEC SQL [PERFORMING <form>].
<Native SQL statement>
ENDEXEC.
There is no period after Native SQL statements. Furthermore, using inverted commas (") or an asterisk (*) at the beginning of a line in a native SQL statement does not introduce a comment as it would in normal ABAP syntax. You need to know whether table and field names are case-sensitive in your chosen database.
In Native SQL statements, the data is transported between the database table and the ABAP program using host variables. These are declared in the ABAP program, and preceded in the Native SQL statement by a colon (:). You can use elementary structures as host variables. Exceptionally, structures in an INTO clause are treated as though all of their fields were listed individually.
If the selection in a Native SQL SELECT statement is a table, you can pass it to ABAP line by line using the PERFORMING addition. The program calls a subroutine <form> for each line read. You can process the data further within the subroutine.
As in Open SQL, after the ENDEXEC statement, SY-DBCNT contains the number of lines processed. In nearly all cases, SY-SUBRC contains the value 0 after the ENDEXEC statement. Cursor operations form an exception: After FETCH, SY-SUBRC is 4 if no more records could be read. This also applies when you read a result set using EXEC SQL PERFORMING.
EXEC SQL PERFORMING loop_output.
SELECT connid, cityfrom, cityto
INTO :wa
FROM spfli
WHERE carrid = :c1
ENDEXEC.

Incorrectly read attributes with custom SQL query

Hi folks,
I'm trying to read in a random sampling of records from a table, so I tried:
ReadAllQuery q = new ReadAllQuery();
q.setReferenceClass(Foo.class);
q.addPartialAttribute("bar");
q.setSQLString("select * from Foo sample(10)");
q.useCursoredStream(100,100, new ValueReadQuery("select count(*) from Foo sample(10)"));
This all worked fine, the Foos were retrieved, but after the first dozen or so, all the "bar" attributes were null, which they should not be. This only occurs when using a custom SQL string. I tried bringing back all the objects (i.e., without using setSQLString) and examining them and all the "bar"s were present. But when I use setSQLString the attributes don't get read correctly.
Can anyone tell me what I'm doing wrong? Is there a better way to do it?
Thanks,

Okay, here's the actual code:
ReadAllQuery q = new ReadAllQuery();
q.setReferenceClass(ActivityCenter.class);
boolean useCustom = true;
if (useCustom) {
q.setSQLString("SELECT SetupDt, TerminationDt, ReinstateDt, IID, upDt, ID, " +
"Stat, SubType, Acct FROM ACtr");
q.useCursoredStream(100,100, new ValueReadQuery("select count(IID) from actr"));
} else {
q.useCursoredStream(100,100);
session.logMessages();
activityCenters = (CursoredStream) session.executeQuery(q);
ActivityCenter ac = (ActivityCenter) activityCenters.read();
if (ac.getAccount() == null) {
System.err.println(ac.getID() + ": Oops!");
} else {
System.err.println(ac.getID() + ": Has account!");
System.exit(0);
So, everything about this program is the same - how the mapping is done, how things get initialized, everything. The only difference is whether I use a custom SQL query or not. Here's what it looks like when I run it both ways:
First, custom:
DatabaseSession(2433702)--Connection(393272)--SELECT SetupDt, TerminationDt, ReinstateDt, IID, upDt, ID, Stat, SubType, Acct FROM ACtr
1.1: Oops!
Now, without the custom SQL:
DatabaseSession(393272)--Connection(7896086)--SELECT SetupDt, TerminationDt, ReinstateDt, IID, upDt, ID, Stat, SubType, Acct FROM ACtr
DatabaseSession(393272)--Connection(7896086)--SELECT
//bunch of fields from the Acct attribute...
FROM Acct WHERE (IID= 'ffbe5c47f3ea762cfd50fbe9e6d6de6')
1.1: Has account!
Notice that the first query on Actr is identical in both cases. Also note there are no null Actr.acct fields in the database:
SQL> select * from actr where actr.acct is null;
no rows selected
SQL>
This is on Oracle 9i, with the thin jdbc driver.
Also, I was curious that you asked if I was using partial attributes - when I try to add a partial attribute when using the custom SQL string, I get exceptions like this one:
java.lang.ClassCastException: oracle.toplink.internal.queryframework.CallQueryMechanism
at oracle.toplink.queryframework.ObjectLevelReadQuery.initializeDefaultBuilder(Unknown Source)

Submit button executes a sql query

In my servlet I'd like to create a submit button, and when it is clicked I want to execute an sql query.
For example;
If I write a name; I want to add that name to my table in my database.
Could you give an example please?
Thank you

PreparedStatement ps = con.prepareStatement("insert into foo (name, birthdate) values (?, ?)"); // double check my sql insert syntax. I'm not sure if it's right.
String theName = ...; // get name from what user enters
Date theBirthDate =...; // likewise birthdate
ps.setString(1, theName);
ps.setDate(2, theBirthDate);
ps.executeUpdate(); Look at the APIs or google for java preparedstatement tutorial or something for more info.

Obtaining "rows selected" value after custom sql query in Database adaptor

We are executing a custom query in a database adaptor. With other technologies (JDBC, etc.) the result of a query will not only produce a result set but a count of the number of rows selected. E.G. the script output of Oracle SQL Developer will print out something like:
9999 rows selected
at the end of the script output.
I would like to obtain this value for a BPEL process. Of course, I could execute a 2nd query whose where clause is identical to the first, but selects count(*) instead. However, this is not only inefficient but (in rare circumstances in an active database) could be wrong.
It is not obvious to this BPEL novice how to obtain the row selected value as well as the result set in one Invoke. Is this possible?

This may not be the only solution - but it is how I have done it in the past.
Following the invoke step of the adapter, use an assign/copy step to populate an integer BPEL variable using the count xpath function...
<assign name="Initialize">
<copy>
<from expression="count(bpws:getVariableData('Invoke_Query_OutputVariable','MyTableQueryCollection','/ns3:MyTableQueryCollection/ns3:MyTableQuery'))"/>
<to variable="NumberOfRecordsReturned"/>
</copy>
</assign>
That should assign the number of records returned by the query.
I hope that helps.
Rod.
