XMLSequence: inconsistent datatypes?

Hello,
I can't get data from XMLsequence into a CLOB using getClobVal().
With the code below I get this error:
The following error has occurred:
ORA-06550: line 7, column 17: [the getClobVal() statement]
PL/SQL: ORA-00932: inconsistent datatypes: expected NUMBER got CLOB
ORA-06550: line 7, column 1:
PL/SQL: SQL Statement ignored
xml_t is defined like this: create or replace type xml_t is VARRAY (2000) of CLOB
OMWB_cv1 is a weak ref cursor (created for my stored procedure by the Oracle Migration Workbench)
I want to use XMLSequence to extract the query as XML snippets, and then I'll aggregate them together in a single CLOB. Any ideas on how to accomplish this without the need to explicitly list out the individual columns would be appreciated, since I need to perform this same operation on 125 stored procedures and would rather write a wrapper than rewrite each one. Thanks.

I'm not sure that I undestand what you are trying to do.
XMLSequence generates a series of XMLType variables, each containing a well formed XML document from a XMLType that contains an XMLFragment. It is typically used in conjunction with the tabel() operator to create a set of rows from a collection.
eg
select count(*) from purchaseorder p,
table(xmlsequence(extract(value(p),'/PurchaseOrder/LineItem'))) t
Would count the number of LineItem elements in each row in the purchaseorder table.

PL/SQL: ORA-00932: inconsistent datatypes: expected UDT got NUMBER

Hi all,
Wondering if you could assist? I'm exploring User Types and having a small problem. I'm getting the above error for a user type I have created which I'm calling in a function. Here's what my code looks like which I'm running the 'scott' schema for testing purposes

Any clues to what I'm doing wrong? Cheers.

The deptno column is a number, you cannot directly select a number into your type, you need to use your type's constructor.
Something like:
CREATE OR REPLACE FUNCTION first_rec_only (NUM_ID IN NUMBER) RETURN NUMBER IS
   v_num NBR_COLL;
BEGIN
   SELECT nbr_coll(deptno) INTO v_num from dept;
   RETURN v_num(v_num.FIRST);
END first_rec_only;Note that although this will compile, it will throw ORA-01422: exact fetch returns more than requested number of rows when you run it. you need to either use the input parameter as a predicate on your query against dept, use rownum = 1 in the query or use bulk BULK COLLECT INTO, depending on what exactly you want to accomplish.

Gavin,
What is your VC2_40 and NAME_T type definition? Your insert used these as varchar2, which is a built-in type not a user-defined type. If you explicitly define these to be varchar2's, the insert statement works fine.
Regards,
Geoff

Function issue: inconsistent datatypes?

Hi all.
I'm having an issue with a function that converts coordinates to a spatial data type.
My database version is:
Oracle Database 11g Enterprise Edition Release 11.2.0.2.0 - Production
PL/SQL Release 11.2.0.2.0 - Production
CORE 11.2.0.2.0 Production
TNS for Linux: Version 11.2.0.2.0 - Production
NLSRTL Version 11.2.0.2.0 - Production
Here's my package that I'm using
create or replace package make_geometry
as
 function get_geometry_from_coords (p_coords in clob )
 return sdo_geometry;
end;
create or replace package body make_geometry
as
 function get_geometry_from_coords (p_coords in clob)
 return sdo_geometry
 is
 v_geometry sdo_geometry;
 begin
 --with t as (select p_coords coords from dual)
 select MDSYS.SDO_GEOMETRY(2003,8307,NULL,MDSYS.SDO_ELEM_INFO_ARRAY(1,1003,1)
 ,cast(multiset(
 select ordset
 from (
 select regexp_substr( regexp_replace(
 replace(p_coords,chr(10))
 ,' {1,}',',')
 ,'[^,]+',1,level) ordset
 ,rownum rn
 from dual
 connect by level <= length(regexp_replace(regexp_replace(
 replace(p_coords,chr(10))
 ,' {1,}',','),'[^,]+')) + 1
 where mod(rn,3) <> 0
 ) as sdo_ordinate_array))
 into v_geometry
 from dual;
 return v_geometry;
 end;
end;
/basically, it takes a list of coordinates, in the following format:
with t as (select '130.88214073599997,-12.377589935499998,0 130.88189276799997,-12.378437734999997,0 130.88164895999998,-12.379271400499997,0 ' coords from dual)replaces the spaces with commas and splits the resultant string by comma, then removes the third coordinate in each set (sets delimited by spaces in above example) and converts the result to sdo_geometry type.
This logic is not where my problem is occurring
If I run the query found in the package separately, it works fine:

any thoughts?

I see two issues off a quick eye-ball of the code 
#1) You insert an empty clob into your table, load a local variable with the XML from disk, and then query the table. You never insert the XML into the table so you are querying on an empty column in the table. 
#2) extractValue allows a third parm which is the namespace string. Since your XPath contains ns1: you'll need to use the third parm

[8i] Case statement generates ORA-00932: inconsistent datatypes

Note: I am working with an 8i database (yes, it is quite old), and in this situation, I have to deal with the datatypes (i.e. CHAR), I am given to work with.
I am attempting to calculate the amount of time product waits between manufacturing steps. As I've discovered though, sometimes I get a negative value when subtracting the date the previous step completes from the date the current step starts. As it is generally impossible to start a later step before an earlier step (imagine trying to screw a cap onto a bottle that doesn't have threads cut yet--it just can't happen), what I've found is that sometimes two steps are started on the same day and finished on the same day (though not necessarily the day they started). This situation CAN happen when one person did both steps and logged on to both steps at the same time, rather than logging on to one, then the other. So, what I need to do in these situations is replace the negative number with a zero (I'll treat the later step as having no wait time).
Here is some sample data:
(Note: the real data set is the result of a query, and has around 200K rows and more columns, but this should be representative enough to find a solution that works on my actual application.)
CREATE TABLE steps
( item_id CHAR(25)

SELECT item_id
, ord_nbr
, sub_nbr
, step_nbr
, start_date - last_step_finished
FROM (
 SELECT s.*
 , LAG (s.finish_date) OVER (
 PARTITION BY s.item_id
 , s.ord_nbr
 , s.sub_nbr
 ORDER BY s.step_nbr
 ) AS last_step_finished
 FROM steps s
Returns:
ITEM_ID ORD_NBR SUB STEP START_DATE-LAST_STEP_FINISHED
A 0000000001 001 0010
A 0000000001 001 0020 -1.000

A 0000000001 002 0030 2.000
B 0000000002 001 0005
B 0000000002 001 0025 -2.000These are the results I want to see:
ITEM_ID ORD_NBR SUB STEP START_DATE-LAST_STEP_FINISHED
A 0000000001 001 0010
A 0000000001 001 0020 0.000
A 0000000001 001 0030 3.000

B 0000000002 001 0005
B 0000000002 001 0025 0.000And this is what I tried to do to get those results (comment notes what line generated the error):
SELECT item_id
, ord_nbr
, sub_nbr
, step_nbr
, CASE
 WHEN start_dt - last_step_finished < 0
 THEN 0
 ELSE start_dt - last_step_finished -- THIS LINE GENERATES THE ORA-00932 ERROR
 END AS days_in_queue
FROM (
 SELECT s.*
 , LAG (s.finish_date) OVER ( PARTITION BY s.item_id
 , s.ord_nbr
 , s.sub_nbr
 ORDER BY s.step_nbr
 ) AS last_step_finished
 FROM steps s
 );I know I've had inconsistent datatype errors before with case statements in this particular 8i database, but I can't seem to figure out why I'm getting one this time. I think it has something to do with the NULL values that can occur for last_step_finished. Also, if I change the case statement to:
, CASE
 WHEN start_dt - last_step_finished < 0
 THEN NULL
 ELSE start_dt - last_step_finished -- THIS LINE GENERATES THE ORA-00932 ERROR
 END the query runs just fine. But, I don't want NULL, I want 0. In the next level of this query, I will be taking averages by item_id/step_nbr, and I want the 0's to be included in the average. (NULL values, as far as I can tell, would be excluded. AVG(NULL, 1, 2) =AVG (1,2) = 1.5 NOT AVG(0,1,2) = 1).
Thanks in advance!

Thanks, TO_NUMBER did the trick. Since you didn't state in your post where to use TO_NUMBER, here is my final solution, in case anyone in the future looks through this thread to find an answer to their question:
SELECT item_id
, ord_nbr
, sub_nbr
, step_nbr
, CASE
 WHEN start_dt - last_step_finished < 0
 THEN 0
 ELSE TO_NUMBER(start_dt - last_step_finished)
 END AS days_in_queue
FROM (
 SELECT s.*
 , LAG (s.finish_date) OVER ( PARTITION BY s.item_id
 , s.ord_nbr
 , s.sub_nbr
 ORDER BY s.step_nbr
 ) AS last_step_finished
 FROM steps s
 );Edited by: user11033437 on Jun 27, 2011 11:17 AM
I see you edited your post to add TO_NUMBER to it.

[Oracle 8i] ORA-00932 Inconsistent Datatypes

Hopefully this is a quick question to answer. In running a query I get the 'inconsistent datatypes' error, and I've narrowed the error down to one part of my query:
SELECT CASE
 WHEN sopn.plan_start_dt < SYSDATE THEN SYSDATE
 ELSE sopn.plan_start_dt
 END
FROM SOPN sopn(replacing SYSDATE with an actual hard-coded date doesn't work either)
The field sopn.plan_start_dt is definitely a date datatype. If I do a simple query for just that field with a date parameter in my where statement, it works just fine, for example:
SELECT sopn.plan_start_dt
FROM SOPN sopn
WHERE sopn.plan_start_dt<SYSDATEdoes not give me any errors.
I'm guessing there's something wrong with my case statement, or maybe case statements with date parameters are something Oracle 8i doesn't get along with...
If anyone can tell me why my case statement is causing an 'inconsistent datatype' error, I'd appreciate it. Thanks!

Well, this tells me column sopn.plan_start_dt datatype is not DATE. CASE requires all branches to return same type expressions. Most likely sopn.plan_start_dt is VARCHAR2 and it is very bad coding to rely on implicit comversions. Use TO_DATE with proper format. For example:
SELECT CASE
 WHEN TO_DATE(sopn.plan_start_dt,'DD-MON-YY') < SYSDATE THEN SYSDATE
 ELSE TO_DATE(sopn.plan_start_dt,'DD-MON-YY')
 END
FROM SOPN sopnSY.

A problem with inconsistent datatypes

Whenever I try inserting a new record of type t_cliente_societa in my Cliente table, I get ORA-00932 inconsistent datatypes error and I'm not able to find the reason.
Could anyone help me? Thanks in advance.
I'll post my SQL code here. please ignore member functions for I havent' included the code necessary to create the needed tables.
I defined some types useful for storing informations about the entities I have to deal with.
The main type is t_cliente and its subtypes are t_cliente_pers and t_cliente_soc.
I use polymorphism to insert records based on subtypes instancies into a table based on supertype.
When I would add a new t_cliente_pers record, first I add it into Persona table and then into Cliente table.
The latter contains a REF to Persona for I have several "persons" who aren't "clients" and I use a single table to store them all.

ORA-00932: inconsistent datatypes: expected - got - In 11g, WORKS in 9i!

Hello,
Involved in migration of a 9i database to 11g, R2. One of our procedures works in 9i but in 11g gives us "ORA-00932: inconsistent datatypes: expected - got - "
We tracked down the error in a statement where oracle does a fetch into a sys_refcursor. The fetch happens on a dynamically constructed select statement ( built by varchar concatenation).
The select statement selects 3 fields, but the fetch into passes 2 variables to the fetch statement. This causes ORA-00932 in 11g R2, but works in 9i.
Below is a modified procedure we built to demonstrate the problem. if you compile and test, you will see that the procedure runs in 9i but not 11g.
create or replace procedure testORA00932 is
v_now date;
v_fsqltext varchar2(2000);
v_curs sys_refcursor;
begin
v_fsqltext := 'select sysdate, sysdate+1 from dual'; -- select 2 fields
open v_curs for v_fsqltext;
loop
fetch v_curs into v_now; -- fetch 1 field, this statement fails in 11g (ORA-00932), works in 9i
dbms_output.put_line(v_now);
exit when v_curs%notfound;
end loop;
close v_curs;
end;
Is there a compatibility flag we can turn on to resove this problem?

After researching this a little more, this is a know bug to oracle: Bug 4381035
According to Oracle, the only available workaround is to provide the same number of define variables as columns in the SELECT statement.

Help with error select case statement (ORA-00932: inconsistent datatypes)

Hi,
I'm struggling to get my sql query work on Oracle..
I have a table MyTable with 5 columns ( Column1, Column2, Column3, Column4, Column5 ) all are of type NVARCHAR2.
I need to check whether Column 3, Column 4 are empty or not in that order..and if they values then I wanna append it to Column2.
For example
If a row contains the following values,
Column 2 = a.b
Column 3 = 123
Column 4 = xyz
then column CA = a.b/123/xyz where column CA = temp column
If either Column 3 or Column 4 is empty/null, then I don't need to append value for that column..
For example
Column 2 = a.b
Column 3 = either NULL or ''
Column 4 = xyz
then CA = a.b/xyz where column CA = temp column
similarly..
Column 2 = a.b
Column 3 = 123
Column 4 = either NULL or ''
then CA = a.b/123 where column CA = temp column
Here is my query..
select MyTable.Column1 as CA0,
MyTable.Column2 as CA1,
MyTable.Column3 as CA2,
MyTable.Column4 as CA3,
MyTable.Column5 as CA4,
MyTable.Column2 + CASE WHEN MyTable.Column3 > '' THEN '/' + MyTable.Column3 ELSE '' END + CASE WHEN MyTable.Column4 > '' THEN '/' + MyTable.Column4 ELSE '' END CA
from MyTable;
This query works just fine against SQL Server db, but gainst Oracle I'm getting
ORA-00932: inconsistent datatypes: expected NUMBER got CHAR
00932. 00000 - "inconsistent datatypes: expected %s got %s"
Could you please let me know what I'm doing wrong. I need to get this query working on both SQL Server and Oracle..
Please let me know your suggestions and thoughts..
Cheers,

I need to check whether Column 3, Column 4 are empty or not in that order..and if they values then I wanna append it to Column2. In Oracle, you can do it this way - no need to do all kinds of difficult things:
select col2||col3||col4
from tbl

ORA00932 inconsistent datatypes For member methods in SQLJ Object called from SQLPlus

Hi, I would very much appreciate advice on the following problem, its a tricky one, here are the full details....
A) EXECUTIVE SUMMARY....
I have created an oracle object type by wrapping a SQLData java object with the Oracle Create type statement. I am using Oracle 9i on NT4. However despite following the very few Oracle examples I could find, I get the following error....
select value(aaa).testint() from dealsobjtab aaa
ORA-00932: inconsistent datatypes
select value(aaa).testme() from dealsobjtab aaa
ORA-00932: inconsistent datatypesHere is what I've done...
1) Create Java object using SQLData interface (see listing below)
2) Load the Java source to Oracle 9i
3) Run the Oracle Create Type statement to wrap the java class
4) Use the objects in a table and successfully insert rows and query attributes using SQLPlus
5) Find I can't pull back data from any instance methods without getting an "inconsistant datatypes" error for both string and int datatypes. (see below for queries and output from SQLPlus)
B) STEP BY STEP DETAILS FOLLOW......
1) Java Source (in file \dealcalcs\Dealtest.java)
package dealcalcs;
import java.sql.SQLException;
import oracle.jdbc.OracleConnection;
import oracle.jdbc.OracleTypes;
import java.sql.*;
public class Dealtest implements SQLData
public static final String SQLNAME = "SWITCHBLADE_DATA.DEALTEST";
public static final int SQLTYPECODE = OracleTypes.STRUCT;
protected java.math.BigDecimal m_dealid;
protected java.sql.Timestamp m_startdate;
protected String m_dealtype;
protected Double m_facevalue;
/* constructor */
public Dealtest() { }
public void readSQL(SQLInput stream, String type)
throws SQLException
setDealid(stream.readBigDecimal());
setStartdate(stream.readTimestamp());
setDealtype(stream.readString());
setFacevalue(new Double(stream.readDouble()));
if (stream.wasNull()) setFacevalue(null);
public void writeSQL(SQLOutput stream)
throws SQLException
stream.writeBigDecimal(getDealid());
stream.writeTimestamp(getStartdate());
stream.writeString(getDealtype());
if (getFacevalue() == null)
stream.writeBigDecimal(null);
else
stream.writeDouble(getFacevalue().doubleValue());
public String getSQLTypeName() throws SQLException
return SQLNAME;
/* accessor methods */
public java.math.BigDecimal getDealid() { return m_dealid; }
public void setDealid(java.math.BigDecimal dealid) { m_dealid = dealid; }
public java.sql.Timestamp getStartdate() { return m_startdate; }
public void setStartdate(java.sql.Timestamp startdate) { m_startdate = startdate; }
public String getDealtype() { return m_dealtype; }
public void setDealtype(String dealtype) { m_dealtype = dealtype; }
public Double getFacevalue() { return m_facevalue; }
public void setFacevalue(Double facevalue) { m_facevalue = facevalue; }
//These last two are the member methods I call
public String testme(){
String tmp = new String("testme worked");
return tmp;
public int testint(){
int tmp = 0;
tmp = 88;
return tmp;
2, 3, 4) Here is how I wrap the uploaded SQLJ object, create a table using it, and put a row in it....
create or replace type deal_t as object
     external name 'dealcalcs.Dealtest'
LANGUAGE JAVA USING SQLData (
DEALID NUMBER (11) external name 'dealid',
STARTDATE DATE external name 'startdate',
DEALTYPE VARCHAR2 (50) external name 'dealtype',
FACEVALUE FLOAT (49) external name 'facevalue',
MEMBER FUNCTION testme RETURN VARCHAR2
     EXTERNAL NAME 'testme() return java.lang.String',
MEMBER FUNCTION testint RETURN NUMBER
     EXTERNAL NAME 'testint() return int'
) not final
create table dealsobjtab of deal_t;
insert into dealsobjtab values ( deal_t(1, to_date('1/jan/1968'), 'NZD/NZD', 500))
COMMIT
5) Here I select attributes from the object table, and select using the two member methods, note that my member methods fail miserably, and advice on fixing this would be much appreciated....
select * from dealsobjtab aaa
DEALID STARTDATE DEALTYPE FACEVALUE
1 01/01/1968 NZD/NZD 500
1 row selected
select value(aaa).dealid from dealsobjtab aaa
VALUE(AAA).DEALID
1
1 row selected
select value(aaa).testint() from dealsobjtab aaa
ORA-00932: inconsistent datatypes
select value(aaa).testme() from dealsobjtab aaa
ORA-00932: inconsistent datatypes
Phew, that was a long email, I hope you are still awake after all that. I have no idea how to solve this, and would really appreciate some advice to get me going.
Yours Sincerely,
Michael Cato

But, i am receiving the error i have mentioned. is it depends on the java version also?
Please suggest..

Error 'Inconsistent datatypes' with Java classes

Hi,
I have some Java classes loaded in Oracle 8.1.6, mapped as Object Types, so when I create one object from PL/SQL, JVM ought to create the matching Java object, communicating via the SQLData interface.
Unfortunately, after the code:
pippo:=OraMailer('mail.server.com','mymail');
that creates the PL/SQL object, any code that use member procedures or function wrapping instance methods of the Java class fails with the error 932: Inconsistent datatypes.
I looked for a mistake in my PL/SQL and Java code, but no error was found.
It is very important: help me!!!
Thx

So here is what you are doing:
ArrayList results = //get employees from database
ListIterator langIt = results.listIterator();
while (langIt.hasNext()) {
Employee emp = langIt.next();
String name2 = emp.getName();
String SSNo = emp.getSSNum();
results.add(name2);
results.add(SSNo);
}So you get a list or Employee objects, then you get an iterator over the list. For each Employee in the list you add the name and SSNo as Strings back to the same list. From the API for ConcurrentModificationException the exception can be thrown when you modify a collection while iterating over the collection - which is precisely what you are doing.
The ListIterator interface allows you to modify the list through its own methods. Try using:
langIt.add(name2);
langIt.add(SSNo);instead.
Why are you taking the name and SSNo out of the Employee object and placing them back in the same List anyway? That makes no sense to me.
