Convert NVARCHAR2 to VARCHAR2 in select statement

I need to convert NVARCHAR2 values to VARCHAR2 in a select statement. Is this possible? The COUNTY_PARCEL_DATA colums are the NVARCHAR2 columns that need converting. I've tried TRANSLATE(COUNTY_PARCEL_DATA.SITUS_STREET_NUMBER USING CHAR_CS), CAST(COUNTY_PARCEL_DATA.SITUS_STREET_NUMBER AS VARCHAR2(100)), CONVERTCS(COUNTY_PARCEL_DATA.SITUS_STREET_NUMBER, 'CHAR_CS') and others directly in the statement for each column. Anything I'm missing? Thanks.

COUNTY_PARCEL_DATA.SITUS_STREET_NUMBER

|| COUNTY_PARCEL_DATA.SITUS_STREET_DIRECTION

|| COUNTY_PARCEL_DATA.SITUS_STREET_NAME

Are you doing the NVARCHAR2 to VARCHAR2 conversions everywhere, see comments below
SELECT BENEFICIARY.NAME_FIRST || ' ' || BENEFICIARY.NAME_LAST AS NAME,
COUNTY_PARCEL_DATA.SITUS_STREET_NUMBER                        <==== Here, obviously

FROM TABLE(SPLIT_STRING (
R_VARS_MAILING_NOTICES.NEIGHBORHOODS
OR R_VARS_MAILING_NOTICES.NEIGHBORHOODS IS NULL)
AND BENEFICIARY.BENEFICIARY_TYPE = 'Tenant';This is assuming that all fields in COUNTY_PARCEL_DATA are NVARCHAR2.

Convert CLOB to XMLType in SELECT statement ?

Hi XML Xperts,
In my Oracle 9.2.0.3 I have 1 table (tab1) with 2 cols (col1 as XMLType and col2 as CLOB). I Inserted in both fields the following same XML data :
<?xml version="1.0"?>
<TABLE_NAME>MY_TABLE</TABLE_NAME>
With the following statement, I can get the data from col1 which is a XMLType column :
SELECT a.col1.extract('//TABLE_NAME/text()').getStringVal() AS "Table Name"
FROM tab1 a
WHERE a.col1.existsNode('/TABLE_NAME') = 1;
How to get the same data FROM col2 whcih is a CLOB column ? Is it possible to transform the CLOB to XMLType in the SELECT statement ?
Note : I cannot change the type of the colulmn col2 to XMLType
Thanks in advance.
Phil

I tested it in 10g and it seems to be OK.
create table clobtoxml(xmldata clob);
insert into clobtoxml
values('<RootE><FirstNode>This is CLOB data to XML</FirstNode></RootE>');
commit;
select sys.xmltype(xmldata).extract('/RootE/FirstNode/text()').getStringVal() from clobtoxml;
This is CLOB data to XML
select sys.xmltype(xmldata).extract('/*') from clobtoxml;

Seems like you want to convert a SQL statement from the ??? dialect to the Oracle dialect. *(It would be useful to indicate the non-ANSI standard SQL you are starting with.)
Part of the problem is that you use several date related functions. Some are unnecessary in Oracle and some need to translated into Oracle functions as found in the Functions section (chapter 5) of the SQL Reference manual at http://www.oracle.com/pls/db102/homepage
Note that columns and expressions of type 'date' in ORacle always contain all of "yyyy mm dd hh mi ss" and you need to format and trauncate as necessary.
Also note that '09-JAN-31' is NOT an Oracle date, but rather a character representation of a date which must be converted to/from a date expression. You will often need to use the to_date() and to_char() functions with a format mask as the second parameter. This is also descreibed in the first 2 chapters of the SQL Reference manual.

Convert long to varchar2

Hi there,
I am looking for a convertion, long to varchar2, in a sql statement.
If I run the following query :
select data_default from user_tab_columns
It works fine in sql developper but when I execute it in my PHP code it returns:
Notice: Undefined index: DATA_DEFAULT in /opt/lampp/htdocs/datamodel/index.php on line 64
This issue is due in the case where the columns has null.
So I try with the NVL function:
select nvl(data_default, 'null') from user_tab_columns
ORA-00932: inconsistent datatypes: expected LONG got CHAR
I found on internet some people are using the substr function but it did not working for me.
select substr(data_default, 1, 2000) from user_tab_columns
ORA-00932: inconsistent datatypes: expected NUMBER got LONG
Any one has an idea ?
Regards !

See this thread as well you can get an exaple user function
ORA-00932: inconsistent datatypes

Convert CLOB to VARCHAR2 in Oracle 8i

Hello all,
I would like to convert a CLOB column from a table to a VARCHAR2.
How can I do this?
I would like that this works in Oracle 8i, 9i and 10g.
Thank you very much.

Hello APC,
I found the problem.
I have Oracle Reports 6i + patch 17.
The problem was that I couldn't select a CLOB column and store his value in a CLOB variable.
I needed to do the conversion DBMS_LOB.SUBSTR in the select statement and store his value in a VARCHAR2 variable.
Thank you

Re-use SELECT statement in several procedures (other than copy-and-paste)

Our site uses a procedure of the following procedure construct to generate Excel spreadsheets:
TYPE retCur is REF CURSOR;
PROCEDURE get_data_for_excel (
p_filter1 VARCHAR2
,p_filter2 VARCHAR2
,c_OutCursor out retCur
IS
retCursor retcur
BEGIN
BEGIN
OPEN c_OutCursor FOR
    SELECT XMLELEMENT("TR", XMLFOREST(
       "col1" AS "TD"
       ,"col2" AS "TD"
       ,"col3" AS "TD"
      )).getstringval()DATA FROM (SELECT * FROM
   SELECT col1, col2, col3
   FROM sometable
   WHERE somecolumn = p_filter1
    AND someothercolumn = p_filter2
   ) x);
END;
END get_data_for_excel
My question is, the subselect:
SELECT col1, col2, col3
FROM sometable
is used in another procedure. Is there a way to reuse the select from the other procedure into this procedure so we don't copy-and-paste each time the other procedure is changed?
Thanks a lot.

This is a design decision you need to make BEFORE it goes into production.
Right now you have
procedure get_data_for_excel (
   p_filter1 VARCHAR2
,p_filter2 VARCHAR2
,c_OutCursor out retCur );
What, I think jihuyao is trying to say is: convert it to a pipelined function.
I agree with jihuyao as I have ran into to this problem before.
create type d4e_t as object ( DATA xmltype);
create type d4e_table is table of d4e_t;
create or replace function get_data_for_excel (
   p_filter1 VARCHAR2
,p_filter2 VARCHAR2 )
return d4e_table pipelined;
as
begin
for curr in ( --start of SELECT statement
SELECT XMLELEMENT("TR", XMLFOREST(
       "col1" AS "TD"
       ,"col2" AS "TD"
       ,"col3" AS "TD"
      )).getstringval()DATA FROM (SELECT * FROM
   SELECT col1, col2, col3
   FROM sometable
   WHERE somecolumn = p_filter1
    AND someothercolumn = p_filter2
   ) x) )
LOOP
pipe row( d4e_t( curr.data ) );
end loop;
return;
end;
From there, you use it elsewhere as if it were a table.
insert into t
select X.data from table( get_data_for_excel( l_var1, l_var2 ) ) X;

How to create a cursor on a union select statement?

Hi,
Using Oracle 10g RAC +ASM ( RELEASE 1002000300)
What are is the proper way to create a cursor on a union select statement?
Is it possible?
code lines, Results in PLS-00201 error: sT := crsR.STATUS; sS := crsR.TIME;
Procedure listed below:
CREATE OR REPLACE PROCEDURE BUILD_SUMMARY IS
CURSOR csrO IS
SELECT
STATUS,
TIME
FROM (
SELECT
SUBSTR(DESCRIPTION,1,50) STATUS,
TO_CHAR(TIMESTAMP,'MM/DD/YY hh12:mi:ss') TIME
FROM GLOBALSALES.CUBE_STATUS
UNION ALL
SELECT
' TOTAL BUILD TIME',
TO_CHAR(TO_DATE('00:00:00','HH24:MI:SS') +(MAX(TIMESTAMP) - MIN(TIMESTAMP)), 'HH24:MI:SS')
FROM GLOBALSALES.CUBE_STATUS);
csrR csrO%ROWTYPE;
sT LONG :='';
sS LONG :='';
BEGIN
FOR csrR IN csrO
LOOP
sT := crsR.STATUS;
sS := crsR.TIME;
DBMS_OUTPUT.PUT_LINE(sT || ' ' || sS);
END LOOP;
END;
/

csrR csrO%ROWTYPE;
Declares the csrR correct? Cursor Record of Cursor Object Type?That line declares one variable CSRR with your column structure described by the cursor (CSRO) type you declared above it. It means the CSRR variable has the columns you had in the SELECT statement in that cursor.
When you run a cursor as you did you don't need to declare the record variable. Try this:
CREATE OR REPLACE PROCEDURE build_summary IS
CURSOR csro IS
    SELECT status, TIME
      FROM (SELECT substr(description, 1, 50) status, to_char(TIMESTAMP, 'MM/DD/YY hh12:mi:ss') TIME
              FROM globalsales.cube_status
            UNION ALL
            SELECT ' TOTAL BUILD TIME',
                   to_char(to_date('00:00:00', 'HH24:MI:SS') + (MAX(TIMESTAMP) - MIN(TIMESTAMP)),
                           'HH24:MI:SS')
              FROM globalsales.cube_status);
--csrr csro%ROWTYPE;
st   LONG := '';
ss   LONG := '';
BEGIN
FOR csrr IN csro
LOOP
    st := csrr.status;
    ss := csrr.time;
    dbms_output.put_line(st || ' ' || ss);
END LOOP;
END;Also why are you using LONG? It's a deprecated data type and Oracle recommends against using it. Either pick varchar2(4000) or CLOB.
DBMS_OUTPUT.PUT_LINE will implicitly convert that LONG data type anyway.

Select statement operators in ecc 6.

Hi Experts,
I have a small doubt about the '>=' ( greater than or equal to ) operator usage in select statement. Is this operator by any chance perform not as desired in ECC 6.0. Is it a good option to use 'GE' instead of '>='. ?
It may sound a bit awkward, but still I would like to know. I am facing a situation, which could be related to this. An early response would be highly appreciated.
I would request,you NOT TO REPLY with links/explanations which says how to use select statement. Only answer if you have the answers related to this query.

????? Every Open SQL statements is translated to the SQL slang the underlying database is talking regardless if you type GE or >=
If the result differs using >= or GE i would open a call at SAP instead of asking in SDN.

If I want to order by dateAdded to I have to include it in the select statement like

If I do this:
<cfquery name="chart" datasource="#datasource#">
select behaviourID,score, dateAdded2 = convert(varchar,
dateAdded , 101)
from staff_charts_data
where userID =
<cfqueryparam value="#arguments.userID#"
cfsqltype="cf_sql_integer"> AND
NOT score = 5
</cfquery>
If I want to order by dateAdded to I have to include it in
the select statement like so:
<cfquery name="chart" datasource="#datasource#">
select behaviourID,score, dateAdded2 = convert(varchar,
dateAdded , 101),dateAdded
from staff_charts_data
where userID =
<cfqueryparam value="#arguments.userID#"
cfsqltype="cf_sql_integer"> AND
NOT score = 5
</cfquery>

you should be able to order by dateAdded without it being in
the select clause. The only time the order by field has to be in
the select clause is when your query has an aggregate and group by
clause, like this:
select field1, field2, max(field3) as youralias
from sometables
where whatever
group by field1, field2
order by ???
You can only order field1, field2, max(field3) or youralias.
You can't order by field4.

Select statement in a function does Full Table Scan

All,
I have been coding a stored procedure that writes 38K rows in less than a minute. If I add another column which requires call to a package and 4 functions within that package, it runs for about 4 hours. I have confirmed that due to problems in one of the functions, the code does full table scans. The package and all of its functions were written by other contractors who have been long gone.
Please note that case_number_in (VARCHAR2) and effective_date_in (DATE) are parameters sent to the problem function and I have verified through TOAD’s debugger that their values are correct.
Table named ps2_benefit_register has over 40 million rows but case_number is an index for that table.
Table named ps1_case_fs has more than 20 million rows but also uses case_number as an index.
Select #1 – causes full table scan runs and writes 38K rows in a couple of hours.
{case}
SELECT max(a2.application_date)
INTO l_app_date
FROM dwfssd.ps2_benefit_register a1, dwfssd.ps2_case_fs a2
WHERE a2.case_number = case_number_in and
a1.case_number = a2.case_number and
a2.application_date <= effective_date_in and
a1.DOCUMENT_TYPE = 'F';
{case}
Select #2 – runs – hard coding values makes the code to write the same 38K rows in a few minutes.
{case}
SELECT max(a2.application_date)
INTO l_app_date
FROM dwfssd.ps2_benefit_register a1, dwfssd.ps2_case_fs a2
WHERE a2.case_number = 'A006438' and
a1.case_number = a2.case_number and
a2.application_date <= '01-Apr-2009' and
a1.DOCUMENT_TYPE = 'F';
{case}
Why using the values in the passed parameter in the first select statement causes full table scan?
Thank you for your help,
Seyed

IF-ELSE issue in Select Statement

Hello,
I have following query in SQL Server which I am trying to convert to Oracle 11g.
IF '[Param.1]' = 'S' OR '[Param.1]' = 'T' THEN
select * from ULQUEUE
END IF
But when I write the same query in Oracle, it gives error stating Invalid SQL Statement. So how do I incorporate IF-ELSE in Select Statement in Oracle?

Hi,
First of all, remove asterisk sign from the end of line
select * from ULQUEUE;* Second: where you try to put this code? This is not SQL, but PL\SQL so you have to have some variable where you want to put query result like this:
declare
x ULQUEUE%Rowtype;
begin
select *
into x
from ULQUEUE
end; This of course works when your query returns only one row. Otherwise process data in the loop or put result into array.
