SQL & PL/SQL :: Using VArray For Known Column Names?
May 2, 2013
I am trying to build an array that contains known column names, 63 columns in all.The idea is to search backwards from 63 down to say 10 to find the first non-blank column.
Then using a loop with the known number of lines print from 1 to last non-blank column.The problem is that it only shows the column names and not the values of the columns.So I am getting 63 lines every time, instead of 20, 30, 40 or however how many fields actually have something.
Here is my
declare
to_num number;
field_name varchar2(15);
[code]....

I have 20 tables. In all 20 tables, some of column names are same and some are different. I need to find all column names in all 20 tables that have same names.
create table t1 (
col1 varchar2(10),
col2 varchar2(10));
create table t2 (
col1 varchar2(10),
col3 varchar2(10));
create table t3 (
col1 varchar2(10));

I have to move the data from a Varray column to a table.
Lets say I have created a Varray as described below,
create or replace TYPE "BT_TYPE" AS OBJECT (
R_ID NUMBER,
P_EVENT VARCHAR2(100))
/
create or replace TYPE "BT_VR" AS varray(20) of BT_TYPE
/
And I have a used this Varray as the column datatype in table
Create table BT_MASTER(
BT_ID_SEQNUMBER(5),
BT_DETAILBT_VR);
And this table contains data.
I want to move the data in the VARRAY column BT_DETAIL to another table. I have create a staging table BT_STG which contains a surrogate key column and the columns from the VARRAY. I am creating this staging table at run time.
Create Table BT_STG(
BT_STG_ID NUMBER(5),
R_ID NUMBER(5),
P_EVENT VARCHAR2(100)
);
One way to create this staging table is to query the data dictionary views to get the VARRAY object's columns, datatyeps and create it.
Is there any other simpler way by which I could create a table similar to a VARRAY/Object?
Something similar to,
create table test as select * from BT_VR

I wonder if there is any way to return the columns of an select with its letters lowercase?
I have a piece of code that creates an script wich returns an SQL result to be confronted with some templates. My template have the column names in lowercase and because It is case sensitive the Uppercase returned by Oracle,

I'm writing a procedure that takes a table name as a parameter and I would like to print out the column name with the supporting row entry for each row. I know the logic I'd like to use, but how do you query the metadata to return the column names and store them.

I have limited permissions and am unable to create temp tables.So I would like to use a cursor to "create" a table of sorts then access/query it. But this "table"/cursor would have no column names so how do I refer to the columns? Is there a way to refer to a column by column number rather than column name in a query:
select column1 from tablename where column2 = 'abc'?
Is there a way in a query/update/insert to refer to a column by column number rather than column name?
declare
cursor c1 is
select 'abc', '8-Apr-2013', pk_id from EMPLOYEE where pk_id = '153'
UNION
select '1xyz', '4-10-2013', pk_id from EMPLOYEE where pk_id = '154'
c1_val number;
[code]....

I have a problem with Dynamic SQL.
I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
For that i have used a ref cursor to open and insert the table.
In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
find below the sample code:
TYPE ref_csr IS REF CURSOR;
insert_csr ref_csr;
v_select VARCHAR2 (4000) := NULL;
v_table VARCHAR2 (4000) := NULL;
v_where VARCHAR2 (4000) := NULL;
v_ins_tab VARCHAR2 (4000) := NULL;
v_insert VARCHAR2 (4000) := NULL;
v_ins_query VARCHAR2 (4000) := NULL;
[Code]...
How to fetch the column names here
|| ');';
EXECUTE IMMEDIATE v_ins_query;
END LOOP;

I need to rename only two names in column report_headings1. But in order for me to see all other names I need to use all of them in decode function. Is there an easier way to write this Select Statement.
select days_start, days_to,
decode(report_heading1,'31 Or More days', 'Future', '00 Dispute/Pend', 'Dispute or Pend', '1 to 30 Days', '1 to 30 Days',
'31 to 60 Days', '31 to 60 Days','61 to 90 Days', '61 to 90 Days', '91 Or More Days', '91 Or More Days' ) report_heading1, report_heading2, type
from ar_aging_bucket_lines lines, ar_aging_buckets buckets
where lines.aging_bucket_id = buckets.aging_bucket_id;

See attachment for table creation and table data.
The table tbl_completed has two columns, id and completed. I have created a query that does provide me with the result set that I need, but I need to pivot the rows into columns. So instead of a result set to look like this:
select completed, count(completed) as theCount from tbl_completed group by completed;
COMPLETED THECOUNT
Y 772
N 720
I need a result set to look like this:
COMPLETED,Y,N
THECOUNT,772,720
The best solution that I have discovered is this, but I figuring their might be a better way.
select
(select 'THECOUNT' from dual) as COMPLETED,
(select count(completed) from tbl_completed where completed = 'Y') as Y,
(select count(completed) from tbl_completed where completed = 'N') as N
from dual;
COMPLETED,Y,N
THECOUNT,772,720

I am working on convertion of triggers from SQL SERVER to Oracle. I got them converted using a tool. But not sure how to correct the below trigger which uses '*' in sql server.
Code in SQL SERVER :-
CREATE TRIGGER INSERT_AUDIT ON T_AUDIT
FOR INSERT AS
INSERT INTO T_AUDIT_LOG
SELECT 'INSERT','AFTER', CURRENT_TIMESTAMP, NULL,*
FROM INSERTED
Converted into Oracle:-
CREATE OR REPLACE TRIGGER INSERT_AUDIT
BEFORE INSERT
ON T_AUDIT
FOR EACH ROW
INSERT INTO T_AUDIT_LOG
VALUES ( 'INSERT', 'AFTER', SYSTIMESTAMP, NULL, * );
END;
how can I remove the *. I tried replacing the * with the rest column names prefixing with :NEW.
the last 3 columns when are c_data1,c_data2,c_data3 as :-
INSERT INTO T_AUDIT_LOG
VALUES ( 'INSERT', 'AFTER',SYSTIMESTAMP NULL, :NEW.c_data1,:NEW.c_data2,:NEW.c_data3);
But this gives error:-
PLS-00049: bad bind variable 'NEW.C_DATA1'
PLS-00049: bad bind variable 'NEW.C_DATA2'
PLS-00049: bad bind variable 'NEW.C_DATA3'
how can I convert this code.

What I am trying to do is print out page that displays all of the column titles and the data under them for a query given by the user. It is then going to be put into an excel spreadsheet.
I've done this before with Java, simply by using the getMetaData function, but I can't seem to find an alternative for PL/SQL. It seems at the very least I need to know the number of columns in a query, but that would defeat the purpose of this.
Is what I am trying to do even possible or is knowing the column names an absolute necessity when printing table data?

I want the output from two tables with rows to columns and generate dynamic basing on the columns.
For example: Table A (a1) , Table B(a1,b1)
Data: A B
------ ----
a1 a1 b1
--- ---- ----
1 1 x
2 1 y
3 2 a
2 b
2 c
o/p: Columnname col_1 col_2 col_3
-----------------------------------------------
a1 b1_1 b1_2 b1_3
----- ---------------------
1 x y
2 a b c
Columns should be generated based on the second table second column.

it seems that oracle data reader on some client machine is case sensitive. We are using oracle 10g. 2 client machines connect to the same DB and run the same code - one works and another doesn't. they are both using odac 2.111.7.20.
this is my .NET code (which works fine on every environment it was installed in the last 2 years):
using (OracleConnection sqlConn = new OracleConnection())
{
sqlConn.ConnectionString = connectionString;
using (OracleCommand sqlCmd = new OracleCommand())
{
sqlCmd.CommandType = CommandType.StoredProcedure;
sqlCmd.CommandText = "getValues";
[code].......
this is the oracle procedure:
PROCEDURE getValues(
rc IN OUT sys_refcursor
)
IS
BEGIN
OPEN rc FOR
SELECT Name, Value FROM MySchema.MyTable;
END;
The problem that we saw was that on one of the client machines dr["Name"] threw exception :
Error Source: Oracle.DataAccess.Client.OracleDataReader.GetOrdinal
Error Message: System.IndexOutOfRangeException: Unable to find specified column in result set
at Oracle.DataAccess.Client.OracleDataReader.GetOrdinal(String name)
at Oracle.DataAccess.Client.OracleDataReader.get_Item(String columnName)
We modified the code and used NAME instead of Name and it worked!! (dr["NAME"] instead of dr["Name"])
How can it be? from oracle documentation:
A case-sensitive search is made to locate the specified column by its name. If this fails, then a case-insensitive search is made.
My question is what can cause such a behavior? Some ODAC/ODP definitions, .NET configuration?
