I want to join two columns, one with a Long and another with a Varchar2.
How to achieve that?
query to know number of columns in a table i.e.
if I want to know how many number of colums are present in a specific table then what would be the query.
I am using below query for collect
select account_id_N,collect(connection_id_v) from My_test_table group by account_id_n;
but its giving me error as below.
ORA-00932: inconsistent datatypes: expected NUMBER got -
00932. 00000 - "inconsistent datatypes: expected %s got %s"
*Cause:
*Action:
I want to pass Number of columns dynamically to a query. I got success in SQL.
SQL> select &column_list from emp;
Enter value for column_list: empno,ename,sal

14 rows selected.
But the same i need to achieve in pl/sql. I try with the Ref cursor, but not succeeded.
My table looks like this ->
Dp_value
124325
2434
3536
3536
Code is ->
(case when CL.DECIMALPLACES = 0 and CL.FIELDTYPE = 'D' and cl.DATATYPE = 'N'
then trim(dp."Value")*1000
else dp."Value" end) as dp_value,
What I am trying to do ->
From another table cl I want to say if decimal place is 0, fieldtype is decimal (D/C) and datatype is number (N/T)then multiply the number with 1000.
If not then leave it as it is.
When I run my code I get the error:
ORA-00932 : inconsistent datatypes: expected NUMBER got CHAR
for else dp."Value" end)
I need to write a dynamic SQL in PL SQL to query an unknown number of columns. Let me take a simple example query here:
SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS
If I have known the number of columns, e.g. querying two columns: "FIRST_NAME" and "LAST_NAME", I can write a DYNAMIC SQL based on the template in table 8-2 of URL....
DECLARE
stmt_str varchar2(200);
cur_hdl int;
rows_processed int;
FIRST_NAME varchar2(200);
LAST_NAME varchar2(200);
BEGIN
cur_hdl := dbms_sql.open_cursor; -- open cursor
stmt_str := 'SELECT FIRST_NAME, LAST_NAME FROM VENDOR_CONTACTS';
[code]....
However, if I wish to write a dynamical sql to query these two columns for a more general purpose (which should meet the requirement to query different number of columns, e.g. three columns, FIRST_NAME, LAST_NAME, BIRTHDAY instead of two columns FIRST_NAME and LAST_NAME). To do this I first try to query the same two columns but using a different method, following URL.....My code for the same query has error, and I cannot solve it.
DECLARE
stmt_str varchar2(200);
cur_hdl int;
rows_processed int;
l_columns dbms_sql.desc_tab;
l_dummy NUMBER;
l_value NUMBER;
[code]....
I see you can build an address object consisting of street name and number, city and so on, and use this in CREATE TABLE, so all tables use the same fields for addresses. And moreover you can add check functions to prevent street numbers to be negative for instance in the constructor. You can even use inheritance. I like that.
However, all teaching on this subject I found on the Internet starts with structs (points consisting of x and y, persons consisting of name and address, etc.). Then they go to inheritance and show how to build an employee who is just a person plus an employee number. They never start with simple types.
What I would like to do would be rather to start with basic types such as number or varchar2 and inherit from them. An EAN is a VARCHAR2 holding only digits where the last digit is a check sum that must be matched. An item number may be a VARCHAR2 matching 'NNN-AAAA'. A simple string may be a VARCHAR2 where no functional characters such as carriage return, etc. occur.
I would then write my create table statement thus:
CREATE TABLE item (itemno T_ITEMNO, ean T_EAN, itemname T_SIMPLESTRING); and inserts like INSERT INTO item values('123--BCD', '1234567890abc', 'toy') would fail with exceptions like 'item numbers must be formatted NNN-AAAA' or '1234567890abc is not a valid EAN'.
However this seems not possible:
create or replace type T_EAN under varchar2
(
constructor function T_EAN(p_string in varchar2) return self as result
);
fails with "PLS-00580: supertype must be an object type".
Rather than creating completely new types, I would start with extending existing types, but this seems not possible. Is that really impossible or am I using the wrong approach?
Today we faced one strange issue Varchar doesnot print the zero front of number
eg
SQL> select agent_code from table_name where AGENT_CODE = 0061;
AGENT_CODE
----------
61
61
where in my database agent_code columns as value 0061 and 061 for both it shows same value.
I have procedure that is used by trigger but I define it as Varchar2 it's result show number.
change my PLSQL to use as varchar,
If trigger fired, the procedure make this query
select CB_SMS_FLAG, CB_SMS_DT from TM_SFS_CUST_04 where CUST_NUM = 01071234151;
but I want this query
select CB_SMS_FLAG, CB_SMS_DT from TM_SFS_CUST_04 where CUST_NUM ='01071234151';
because CUST_NUM is VARCHAR2(12)
so it can use index appropriately.
how can I change my PLSQL this sentence,
v_sel_sql1 := 'select CB_SMS_FLAG, CB_SMS_DT from ' || pTBL_NM ||' where CUST_NUM = ' || pCUST_NUM;
Here my code
CREATE OR REPLACE PROCEDURE ORAASFS.P_TM_SFS_CB_SMS_CNT_upd_104(
gKIND VARCHAR2,
pCUST_NUM VARCHAR2,
pSMS_CNT NUMBER,
pSMS_CLC VARCHAR2,
pRD_FLAG VARCHAR2,

I have the following Union All query. It throws the following error in SQL plus
ERROR at line 27: ORA-01789: query block has incorrect number of result columns
After doing some google for the above error it suggests there are incorrect number of columns in the Union All query.I could not figure out the exact location well SQl Plus says error is on line 27 at the first opening bracket like
(Select distinct c.contact_code
Following is the SQL query
Select
tbl_contact.contact_code,
contact_title
||'.'||contact_name contact_name,
contact_address,

I would like to know if using varchar parameter in sql queries with number column can result in performance degrade.
Ex: Procedure testa ( myparam varchar) is
begin
select col1 into var1 from table where colno = myparam;
end;
Here col no is a number column and myparam is varchar. I feel its better to change the parameter to number.
I have a two question.
Question 1:How to select all columns from table except those columns which i type in query
Question 2:How to select all columns from table where all columns are not null without type each column name which is in empty data
I have the following select query that works perfectly fine. Returns 25 rows based on the descending order of the price.But, I want add one more expression to this list of columns in this query (apart from customer_id).
the expression should look like Cust-01 for the first customer from the below query all the way to Cust-25 for the last customer.But how can I can generate 01 to 25 in oracle?
select customer_id from
(select customer_id from capitalPLAN
where member_status = 'MEMBER' AND customer_id NOT in ('156','201','1385','2125','3906','165')
order by price desc
)
where rownum <= 25
in retrieve column data in the cursor.My requirement is I created a table dynamically as I don't know how many fields will be there.And the table structure would be like this
Filed1 varchar2(10)
Filed2 varchar2(10)
-----------
-----------
Filedn-1 varchar2(10)
Filedn varchar2(10)

As in the cur.filed value.
I've created a stored procedure which creates itself a view (a MV to be honest); the instructions to create this m.view are dinamically built insinde my procedure, so each time i run it, based on the different input parameters, i've got a different result (my output m.view can have three colums the first time, or ten the next time) how can I read my output view to put the data into file? I've tried with "select * bulk collect into my_array from my_ output_ view"...after declaring "my_array" as a varying array with the max number of colums I could ever have...but nothing: if the array dimension doesn't match the number of columns that i've on my view, i.e. i receive "ora-00947 not enough values" error.
Is there a method to dimension dinamucally the array to store my data? Or should I change the code to fetch some other way the data i need to put to a file?
My goal is this:I have a table which is being updated/changed by lay people with certain types of values. Constraints are given to them, but they need not conform to them as they update the table in excel.Now, I want to validate this table every-time before I use it. i.e. implement a script which can be run to verify is all the values are in the right format for further usage.
I have a variable number of columns (i.e. users can add further columns as their requirements change).From columns 3 to 'n' (depending on table given) the values should be 'Yes' or 'No'. How do I check this for a variable number of columns in PL/SQL?
in my oci applications,if i get a column of number that is in the scope of int,i can use value = *(int *)field.data; get the value,but if the column size is larger than 10,the code can't be available,how can i get the value.

Like such
create table testTable (column1 number(15), column2 number(15));
insert into testTable values (1,5);I need to find the numbers between column 1 and column 2 including the column 1's number and column's 2 number.
so my answer set should be

how to update the middle of plenty rows in the middle of the columns
sample_data
id name state REGION LOC
1 v A.p 1 1
2 a
3 g K.A 0 3
4 y
5 i T.N 1 0
6 l M.P 0 1
7 c U.P
This is sample data,and i have this kind of large data and i need to fill the rows which are empty. In three columns state,region,loc with data like 0,web_intimation,1,
I want to add a variable number of new columns to an existing table temp (with column provided).
Example:
NewColumnNo = 4
-> the columns shall be named rate_1, rate_2, rate_3 and rate_4
-> the values shall be = Column / NewColumnNo
The result shall be like this:
create table temp_res (prodid integer, rate_1 number, rate_2 number, rate_3 number, rate_4 number);
insert into temp_res values(1, 0.25, 0.5, 0.75, 1);
insert into temp_res values(2, 0.25, 0.5, 0.75, 1);
insert into temp_res values(3, 0.25, 0.5, 0.75, 1);
insert into temp_res values(4, 0.25, 0.5, 0.75, 1);
insert into temp_res values(5, 0.25, 0.5, 0.75, 1);
insert into temp_res values(6, 0.25, 0.5, 0.75, 1);
insert into temp_res values(7, 0.25, 0.5, 0.75, 1);
insert into temp_res values(8, 0.25, 0.5, 0.75, 1);
insert into temp_res values(9, 0.25, 0.5, 0.75, 1);
if there is any inbuilt function or way to find a row in the table that is having value for maximum number of columns.
For example, the table A has 5 columns
(c1,c2,c3,c4,c5) and it has 3 records(r1,r2,r3)
and
r1 has values only for c1,c2
r2 has values only for c1,c2,c3,c4
r3 has values only for c1
so I should get the result as "r3 has values for 4 columns & it is not having value for column c5".
The below sql is giving different number of result sets while adding further columns in select clause.i.e After adding the columns 4,5,6 in the below query its giving different number of result set.In this case the result set count would be 5.
Before adding the columns 4,5,6,the result set count was 11.
SELECT PAYMENT_METHOD_MAP.NETTINGGROUP_ID,
PAYMENT_METHOD_MAP.CREDITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.DEBITPAYMENTMETHOD_CD,
PAYMENT_METHOD_MAP.AGENT_ID,

My requirement is to concatenate two column values and place them in a new column.I have done it using self join but it limits the purpose,meaning when I have more than 2 values for grouped columns then it won't work.How to make this dynamic,so that for any number of columns grouped,I can concatenate.
SELECT a.co_nm, a.mnfst_nr, a.mnfst_qty,
a.mnfst_nr || ':' || a.mnfst_qty || ';' || b.mnfst_nr || ':'
|| b.mnfst_qty
FROM vw_acao_critical a JOIN vw_acao_critical b
ON a.co_nm = b.co_nm AND a.mnfst_nr = b.mnfst_nr
[code]......
What will be the case when I need to concatenate for more number of values.
like when co_nm has three bahs and manfst_nr and manfst_qty has 3 values for each for bah.and if three are having same_mnfst nr then I should use something dynamic.how to achieve this.
I have a report with single row having large number of columns . I have to use a scroll bar to see all the columns. Is it possible to design report in below format(half columns on one side of page, half on other side ofpage :
Column1DataColumn11DataColumn2DataColumn12DataColumn3DataColumn13DataColumn4DataColumn14DataColumn5DataColumn15DataColumn6DataColumn16DataColumn7DataColumn17DataColumn8DataColumn18DataColumn9DataColumn19DataColumn10DataColumn20Data I am using Apex 4.2.3 version on oracle 11g xe.
I have a column in a database that contains both numerical and char data. I would like to be able to do two different things (two different queries)
1. divide the numerical data in the column by 10 and leave the char data alone (just return it)
2. detect the numerical data in the column and treat is as a different value so I can run averages & counts on it while disregarding the char data
I'm not at all sure how to do number 2. I thought a CASE statement would work for number 1, but then I realized CASE doesn't like different datatypes:
select
case when '1234' = 'checked' then 'checked'
when '1234' = 'gen.nograde' then 'gen.nograde'
when '1234' = null then null
else '1234'/10 end as "GRADE"

On DB 11.2. I am dynamically building a DB after update trigger that compares old/new column values. I wanted to include a nvl statement in my if conditions as some field values may be blank.
Since I have many different datatypes (varchar,date,number,blob,clob), is there a single nvl comparison I can use that will work against all of these? I was hoping not to have to check the datatype and change my nvl comparison depending on what type it is. i.e.
nvl(x,'1') or nvl(mydate,sysdate)
I'm a beginner in PL/SQL ! --> " get_sql_metadata(p_query IN Varchar2) RETURN VARCHAR2;" I have to display the names and columns of the query by using the package dbms_sql and how can I know how many columns will have my query.
