How to find apostrophes in a VARCHAR2 column

I have a value "GOT UP LATE - DIDN'T HAVE TIME"
stored in varchar2 field of my table through Oracle forms. I want to check whether the values stored in this column have apostrophes or not (e.g. as in DIDN'T). Could any body please let me know how to do this.

You can use the INSTR function
INSTR(string, set[,start[,occurence]])
INSTR('abcdecg', 'c') would return 3 since the 1st occurence of 'c' is at position 3 in the string.
INSTR('abcdecg', 'c', 1, 2) would return 6 since the 2nd occurence of 'c' is at position 6 in the string.
INSTR('abcdecg', 'c', 4) would return 6 since the 1st occurence of 'c', starting at position 4, is at position 6 in the string.
Good luck.

How to find the sum of a column

I need to find the sum of a column and use it in a different column. The following is the example.
Column names: Feedback(Good, Avg, Poor), Count(no of good, no of avg, no of poor) and %age(Feedback/sum(feedback))
I want to find the sum in Java class and also calculate the last column in java class.
Please tell me some way to do it.

oh.. ok ..thanks for letting me know.. i will formulate the question in a proper way:
This is what my UI should look like:
Rating Count Percent
Excellent 2 20
Good 6 60
Poor 1 10
Bad 1 10
Now i have the following columns in the data base:
Meaning and feedback_rating.
So the following SQL Query:
SELECT hrl.meaning rating,
sum(decode(bcpi.feedback_rating, null, 0, 1)) counted
from cmp_cwb_person_info bcpi ,
hr_lookups hrl
group by hrl.meaning
will give me the result as
rating counted
Excellent 2
Good 6
Poor 1
Bad 1
Now I want a third column as percentage : Earlier we were doing this calculation in the sql query itself, so the query was like
SELECT hrl.meaning rating,
sum(decode(bcpi.feedback_rating, null, 0, 1)) counted,
sum(decode(bcpi.feedback_rating, null, 0, 1))/(max (select count (*) from cmp_cwb_person_info bcpi ,
hr_lookups hrl )) percent
from cmp_cwb_person_info bcpi ,
hr_lookups hrl
group by hrl.meaning
Hence the third column (percent) was calculated in the sql query itself.
But now i feel that the performance of the query could be improved if we get the first two columns from the database and the calculate the third column programatically in the java code.
So this is what I want to know. How can i do that?

How to find the new tables and columns in a schema

hi..good morning to all...
I have a schema ABC which owns some objects.
Now some days before I have made another schema XYZ which was a replica of ABC schema.

Acutally i have found , column's max width, its nullability, precision, scale, type, but NOT default value.
I will have to use the default value and nullability while validating user's input.
ResultSetMetaData doesnot contain any method any such method...
Pls help,
how can i do so.
Any idea will be highly appreciated.
Thanks in adv.
Alok

Hi,
After you get the resultset from DatabaseMetaData.getColumns() as shown by sudha_mp you can use the following columns names to retrieve metadata information:
Each column description has the following columns:
TABLE_CAT String => table catalog (may be null)
TABLE_SCHEM String => table schema (may be null)
TABLE_NAME String => table name
COLUMN_NAME String => column name
DATA_TYPE int => SQL type from java.sql.Types
TYPE_NAME String => Data source dependent type name, for a UDT the type name is fully qualified
COLUMN_SIZE int => column size. For char or date types this is the maximum number of characters, for numeric or decimal types this is precision.
BUFFER_LENGTH is not used.
DECIMAL_DIGITS int => the number of fractional digits
NUM_PREC_RADIX int => Radix (typically either 10 or 2)
NULLABLE int => is NULL allowed.
columnNoNulls - might not allow NULL values
columnNullable - definitely allows NULL values
columnNullableUnknown - nullability unknown
REMARKS String => comment describing column (may be null)
COLUMN_DEF String => default value (may be null)
SQL_DATA_TYPE int => unused
SQL_DATETIME_SUB int => unused
CHAR_OCTET_LENGTH int => for char types the maximum number of bytes in the column
ORDINAL_POSITION int => index of column in table (starting at 1)
IS_NULLABLE String => "NO" means column definitely does not allow NULL values; "YES" means the column might allow NULL values. An empty string means nobody knows.
SCOPE_CATLOG String => catalog of table that is the scope of a reference attribute (null if DATA_TYPE isn't REF)
SCOPE_SCHEMA String => schema of table that is the scope of a reference attribute (null if the DATA_TYPE isn't REF)
SCOPE_TABLE String => table name that this the scope of a reference attribure (null if the DATA_TYPE isn't REF)
SOURCE_DATA_TYPE short => source type of a distinct type or user-generated Ref type, SQL type from java.sql.Types (null if DATA_TYPE isn't DISTINCT or user-generated REF)

How to find the difference of two columns in deski

Hi Everyone,
I have a deski report which is build from a single query. The report contains two tables.
Table-1:MTK Loc
           MTKnet
Table-2:WTK Loc
            WTKnet
Now i need to find the difference of the columns WTKnet and MTKnet.
These two are report level variables.Their definitins are as below:
MTKnet:=Sum((<Fees Collected by Per Collected>) In Body) ForEach <vMTKLocation>
WTKnet:=Sum((<Fees Collected by Per Collected>) In Body) ForEach <vWTKLocation>
Where <Fees Collected by Per Collected> is universe variable.
Please help...
Thanks in Advance......

Hi Bol,
As I understand you are taking MTK_Loc and WTK_Loc together in the report which have common values under Fees Collected by Per Collected column.
Please follow the steps mentioned below:
1. Calculate the Variables MTK_Net as
       =Sum(<Fees>) IN <MTK_Loc>
2. Calculate the Variables WTK_Net as
       =Sum(<Fees>) IN <WTK_Loc>
3. You will get the values based on the Locations MTK_Loc and WTK_Loc .
You are using combination of values for MTK_Loc and WTK_Loc hence you will get the variable values in combination.
Insert new column right to the WTK_Net and write the formula name it Variance.
=<MTK_Net>- <WTK_Net>
The values look like :
MTK_Loc      WTK_Loc             MTK_Net                 WTK_Net             Variance
Chicago           Chicago                16,696,274.43      157,168.26            16,539,106.17
Chicago           Madison               16,696,274.43       274,396.12            16,421,878.31
Chicago           Milvaki                 16,696,274.43       16,622,870.97       73,403.46
Chicago           Pennsylvania        16,696,274.43        4,299.35               16,691,975.08
Chicago           Waukesha             16,696,274.43        22,067.08             16,674,207.35
Here you will see values for MTK_Net are repeated because these are based on the MTK_Loc which is same for all rows i.e. Chicago , same is the case with remaining values of MTK_Loc.
We can not calculate variabnce based on the values like Canada,Pennsylvania for all values as these values come in combination of each other and as these are all connected columns WEBI groups Measure data based on the Dimension and variable columns associated with it.
MTK_Loc   WTK_Loc          MTK_Net         WTK_Net          Variance.
Chicago        Chicago           16696274.43        157168.26           16539106.17
However you can compare the values based on the values as :
1. Drag and Drop MTK_Loc and MTK_Loc separately on the report.
2. Drag and Drop WTK_Loc and WTK_Loc separately and put it on the report, Connect it to the columns MTK_Loc and MTK_Loc columns already dragged. Then you can compare the values
MTK_Loc                MTK_Net                         WTK_LOC                    WTK_Net
Chicago                    16,696,274.43                 Chicago                       157,168.26
Madison                   315,705.91                       Madison                      274,396.12
Manitowoc              362,632.50                        Manitowoc                  359,978.50
Milvaki                    54,172.84                          Milvaki                       16,622,870.97
Pennsylvania             2,966.56                           Pennsylvania               4,299.35
Waukesha                 9,028.03                          Waukesha                      22,067.08
Here I unchecked the option avoid duplicate row aggregation (select table-> format table) thatu2019s why it is showing all values as a sum of all MTK_Net and WTK_Net values corresponding to Location values..
Here we are using MTK_Loc and WTK_Loc separately and not connected because though values seems same but they are used in combination ( Chicago, Pennsylvania) in 2 separate tables in DB hence we canu2019t synchronize them by liking these 2 location columns using 2 data providers.
I Hope this is what you want....
Thanks....

You can try one of the following...
sql> select * from temp;
         A          B
    101010     202020
    101011     202021

    101010     202022
    101012     202020
1 select a,b from (
2     select a,
3            b,
4            rank () over (order by a desc, b desc) rnk
5       from temp
6* ) where rnk = 1
sql> /
         A          B
    101012     202021
1 select a,b from (
2    select a,b from temp
3       order by a desc, b desc
4* ) where rownum = 1
sql> /
         A          B
    101012     202021Please try to provide create table statements and insert data scripts instead of "select * from table".
It helps creating your case easier.

How to find the duplicate entries in column

clolum name descripitoin ex:
CLIENT_NAME | Last Name | First Name | Middle Name |suffix | Tendulkar Sachin Ramesh Jr.Sachin

PANno | no | AUBIU1966E
Address | Address of clint | Any address
Insert multiple records as per the e.g. shown in table. Write a oracle procedure in database schema to input the string and identify the possible duplicates from above table.

in this senario clint name column show diffrent names
your query is not working
above three entries are same we need to find aboue three entries are duplicate1. Have one other column called Name2 in the table
2. scan the table and run the "combined" (means you combined every row from below separated by a space) the below output into name2 column
with t as (
     select 'Sachin Tendulkar Ramesh' col from dual
     select TRIM(substr (splitted,
          instr (splitted, ' ', 1, level ) + 1,
          instr (splitted, ' ', 1, level+1) - instr (splitted, ' ', 1, level) -1 )) as ret_row
     from (select ' '||col||' ' splitted
     from t)
     connect by level <= length(splitted)-length(replace(splitted,' ',''))+1
     and instr (splitted, ' ', 1, level+1) - instr (splitted, ' ', 1, level) -1 > 0 order by 1;
3. now run this
select name2,count(*)
the same like above but group by name2, then you will see it

SSRS Reports level how to find out All tables names & columns list to display dynamically SQL Query????

Hi Team,
I Have one requirement,In SSRS Reporsitory 3000 reports are available.
My end user requirement All 3000 reports are used Table names & columns list of each wise to display single table or single result set.
I find out all 3000 reports details are diplayed single results set like
Report Id,Path,Dataset,Source Query Text,Datasource
In Source Query Text column level All reports Queries are available but I want Each Report wise Table name & columns List.If any solution Please share me.
Regards
Rama

Hi Ramakoteswara,
According your description, you want to show used tables and columns of each report, and display is into a single result set. Right?
In this scenario, we don't know where to find a column contains the Source Query Text. With my understanding, in Reporting Services, we have Catalog table in ReportServer DataBase, it has a column called Content stores the report code (.xml). In the
code we can find the Query and Fields. Then you need to use VB/C# code to parse each .xml code of each report and fetch out the table name and columns. We do not support writing any queries against SSRS DataBase or parsing data records in any
table.
If you have any question, please feel free to ask.
Best Regards,

How to find bounds of textcolumn

Hello ,
can anybody tell me ,how to find bounds of textcolumn.

Text columns don't have a geometricBounds property, so you have to calculate that yourself. Take the bounds of the text frame, check the number of columns (myTextFrame.textFramePreferences.textColumnCount) and the gutter width ((myTextFrame.textFramePreferences.textColumnGutter). Then you can work out the bounds of a text column.

hi,
you can use get_item_property built-in
eg:
declare
l_item VARCHAR2(10);
begin
l_item := Get_Item_Property('item_name',DATATYPE);
end;
