I have a column SIX_NO with numbers and null values in it and I would want to display the column with the highest number first and others, in a descending order. I have used the below code
select * from (select six_no from table_name order by six_no desc ) where rownum <=5;
It displays the results as NULL.
I have a table with around 80 columns. All i need is to select first 40 columns.
Is there any way to select first 40 columns without giving all the 40 Column Names in select clause.
i want to select dynamic column names in my select statement in my function.

this is the table i have in which repeated itemids for different dates,for example itemid 205 and 203 comes 2 times because that item was consumed again and again in a different date. like this the table data has more than a 20 thousand records;
In which i need to select the last updated dates itemid from this table, because same item id could be consumed 'n' number of times so i need to select it as per the last date or latest dates itemid from this table for each and every item, so how can i select it?
If there are 100 colums or above in a table and we dont want select a single(any one) column from those 100 columns. is there any command or function to do this in oracle.
I can do it by writting names of all 99 columns but as this method is lenghty, so need some efficient way to do this.
like in SQL server we have a "except" keyword through which we can rule out the columns .
ex: select * except (column_name1,column_name_2)
from Table_name.
By select I got records (see table below) and I need to make select where result will be just one row with all values by payer_flag=Y.
There is a table:

And result should look like:

ck_customer_code | invoice_media | personal_no | cnt_active | cnt_deactive | payer_flag

View 6 Replies View RelatedIs there any way in PL/SQL to select the values from all columns of a table record into an array?
For example:
C1|C2|C3
0 |1 |2
v_array(0) value is 0
v_array(1) values is 1
v_array(2) values is 2
or
v_array(C1) value is 0

explain slow performance of multicolumn indexes on oracle 11g R2 observed in the following scenario? A multi-column index (b-tree index) not partitioned, not unique, not reversed with 3 columns.
A series of queries are run using all 3 columns. The performance hit comes when the first order column values changes. So, maybe after 10 select queries the value changes. The 2nd and 3rd order columns are changing throughout the series of select calls, but no performance bottleneck it hit then.
I am trying to come up with a sql select statement that provides all rows for employees with 2 or more cities.
with sample_table as (
select 'John' name,'city' ValueType,'Toronto' Value from dual union all
select 'John' name,'city' ValueType,'Vancouver' Value from dual union all
select 'Susan' name,'city' ValueType,'Toronto' Value from dual union all
select 'Susan' name,'city' ValueType,'Seattle' Value from dual union all
select 'Susan' name,'age' ValueType,30 Value from dual union all
select 'Susan' name,'city' ValueType,'Atlanta' Value from dual union all
[Code]...
NAME VALUETYPE VALUE
----------- ------------- ------------
John City Toronto
John City Vancouver
Susan City Toronto
Susan City Seattle
Susan Age 30
Susan City Atlanta
David City Chicago
David age 35
David Status married
David City Dallas
The above code is just to describe the sample table and the desired result set. Please note that Mary is not on the result set since she has no city assigned to her. Also Julia is not on the result set since she only has one city assigned to her. The others are there because they had at least 2 cities assigned to them.
I need the sql syntax that would return this result set.
I'm trying to select id's in a table that have 2 certain values for another column. Example below explains:
idCoupon Type
123Amount
123Percent
456Amount
789Percent
I would like to write a sql statement that would select all rows where id=123, because id 123 has both coupon types "Amount" and "Percent". So the result set of the sql statement would look like:
idCoupon Type
123Amount
123Percent
I'm writing a VPD function to be used for column masking. The predicate (WHERE-clause) it generates may take many different forms. In particular, it may contain inner-selects; for example,
"exists(select '*' from B where B.VAL = '123' and A.KEY = B.KEY)"
where A is the table that is associated to the VPD function, and B is some other table.
if this is OK for column masking? If not, my VPD function may sometimes work and sometimes fail, in unexpected ways.
The Oracle Database Security Guide (11g Release 1) says
Column-masking conditions generated by the policy function must be simple Boolean expressions, unlike regular Oracle Virtual Private Database predicates".
This seems to indicate that there are cases where a VPD function works for row-level security, but not for column masking.
an example of a 'regular Oracle VPD predicate' that doesn't work for column-masking?

My objective is to get the name 'Thomas' in the variable - MValue1. I don't want to use the statement MValue1:=MTest1.Name because, moving forward, I want to have the column name to be dynamic, taken from an array of column names.
I need to achieve it by giving only one select query to get entire record and fetch the column values one by one, by substituting the column name from an array of column names, instead of writing that many lines of code / querying that may times to the database.
I have a problem executing a function.
There are two tables,
1. Table with column names of a second table mapped to certain variables.
ex: Table1
col1, var1
col2, var2
col3, var3
--------
--------
2. Table with the values for columns as given in table 1 ex:
col1, col2, col3, col4, col5,
a , aa , 1 , x1 , p
b , ab , 2 , x2 , q
c , ac , 3 , x3 , r
I have to select values from table2.col1 do some processing and calculate values and store it in a table then do the same thing with col2 and so. This needs to be done for all the columns that appear in table1.For example in table 1 i have only three columns mentioned thus i have to process col1, col2 and col3 from table2. col4 and col5 will not be processed since they do not appear in the first table.
The problem is i have hundred columns in table 2 and the user can add up to hundred columns in table 1 as and when it is required.
I have created a cursor to first select column name from table 1 where variable is not null.For each value in cursor i put it in a local variable.
Second step is to select values from table2 where instead of column name i am using the local variable.But the problem is instead of choosing values from col1 the query returns the value as col1 (the value of local variable)
I have following tables with data as under:
table1: table2:
column1 (char) column1 (char) column2 (num)
A A 10
B A 20
C B 15
D C 12
E D 25
D 9
I need to generate output as :
column1 column2
A A10, A20
B B15
C C12
D D25,D9
E null
Is there anyway to achieve this thru simple SELECT ...and if not, then thru any PL/SQL construct..?
I have table desc xx_testName

(4.) i.e. We need to use SQL statements and
(a.) Get all contents of the PDF/MS WORD doc.
(b.) Search for specific strings inside these docs in the BLOB columns.

I need to write a query in plsql to select records for first 3 distinct values of a single column (below example, ID )and all the rows for next 3 distinct values of the column and so on till the end of count of distinct values of a column.

1 abc 10
1 def 20
2 ghi 10
2 jkl 20
2 mno 60
3 pqr 10
4 rst 10
4 tuv 10
5 vwx 10
6 xyz 10
6 hij 10
7 lmn 10

Query 1 should result --->
ID name age
1 abc 10
1 def 20
2 ghi 10
2 jkl 20
2 mno 60
3 pqr 10
query 2 should result -->
