Query to sort a column containing alphanumeric values
Hi,
I have a table whose column contains ALPHANUMERIC values. The column is of type VARCHAR(1).
I tried many queries (using UNION) to fetch records in Alphabets first and Numbers as last
I.e. A-Z should come first and then 0-9 values.
Please do the needful
Regards,
Mradul
I.e. A-Z should come first and then 0-9 values.Edit: Whoops, I forgot the ascii values for numbers were lower.
WITH t AS
(SELECT '0' c FROM DUAL
UNION
SELECT '9' c FROM DUAL
UNION
SELECT 'A' c FROM DUAL
UNION
SELECT 'B' c FROM DUAL
SELECT c
FROM t
ORDER BY TRANSLATE( UPPER(c)
, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'
, 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
, TRANSLATE( UPPER(c)
, '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ'
, '0123456789'
C
A
B

How do I get a column of alphanumerical to stay sorted? When I go to the next column, my first column gets mixed up.
For my purpose, I'll have to go back to Excel.
What is your purpose? Note that Numbers 3.0 does not have a multicolumn sort interface the way you have in Excel (or Numbers 2.3). But it is generally easy to accomplish what you need to do.
Say you have a column A on which you want an alphanumerical sort and within that you want to sort by B (the equivalent of Excel's "Sort by" A "Then by" B).
First do a single column sort by B. Then do a single column sort by A.

Set a flag if certain columns contain a value
I have a table with multiple different columns. Each of these fields can contain 1 or 0. So how would I write a statement that sets a "flag" if each of these columns contain a 1. Again, I only want the field to be set if
each column in the row contains a 1. I know I can use "nested If statements" but I was wondering if there is a cleaner, more organized way.
Thanks.>> I have a table with multiple different columns. Each of these fields [sic] can contain 1 or 0. So how would I write a statement that sets a "flag" if each of these columns contain a 1. <<
You missed a basic concept; columns are not fields. This is fundamental. Then you do not know that we never use flags in SQL. That was assembly language, not SQL. Please read:

How to sort alphanumeric values in datagrid numerically
Hi all,
I have a datagrid column which contains AlphaNumeric values.Is there a way i can sort these values in a numerical order
eg:
having d1,d11,12,13,d2,d3,d4
d2 should come after d1..
order should be d1,d2,d3,d4,d11,d12,d13
Please help me out..if any have any idea..giving below thw code which is sorting as string
protected function ColumnSortCompare( obj1:Object, obj2:Object ):int
if ( !obj1 && !obj2 )
return 0;
if ( !obj1 )
return 1;
if ( !obj2 )
return -1;
var obj1Data:String = ComplexColumnData( obj1 ).toString();
var obj2Data:String = ComplexColumnData( obj2 ).toString();
if ( obj1Data < obj2Data )
return -1;
if ( obj1Data > obj2Data )
return 1;
return 0;
Thanx in advance
RajeshHi,
Thanks for the reply. Please dont mind if the question is simple,as I am new to flex.
While I am using
return ObjectUtil.stringCompare(obj1[fieldName], obj2[fieldName]);
it is throwing error as, undefined property fieldName.
I am calling as this
<mx:DataGridColumn headerText=""
editable="false"
sortCompareFunction="ColumnSortCompare"
textAlign="left"
dataField="{PORT_NAME}"
width="150"/>
How I can resolve this.Please guide me.
Thanks,

Error changing data type to date in column containing blanks
I am pulling data from an OLAP cube into PowerPivot. My data set contains several date columns wich are formatted as YYYY-MM-DD string values. After successfully importing the data, I am trying to set the data type of these columns to date.
Apparently, when the column contains blank values, the conversion fails:
The following system error occurred: Type mismatch. Datatype conversion failed for [Table: 'SO fact table', Column: 'Shipping Date LastDateDate', Value: ''].
When the column contains no blanks, the conversion succeeds.
Would anyone have an idea for working around this issue ?
Is there some MDX magic that I could use in my query in order to cast blank dates to something that PowerPivot would accept to convert, or to make the conversion to the date format right at the source ?Hello,
I did a quick test with data from Excel sheet formatted as text containing ISO date values with one blank value, in Power Pivot I then changed it to type "Date" and it works without an issue; so it must have an other reason:
You can try to use the
DAX function "DateValue" to convert the values

Functionality to dynamically sort tableview columns
Has anybody successfully tried sorting columns of a tableview component by clicking on its header? I need to sort a column containing dates in mm/dd/yyyy format. Please share your hints or code. BR, Maulin
Hi,
Here is the code, no support included :-):
import java.util.Collections;
import java.util.Comparator;
import java.util.Vector;
import com.sapportals.htmlb.table.DefaultTableViewModel;
public class SortTableModel extends DefaultTableViewModel implements Comparator {
protected int currCol;
protected Vector ascendCol; // this vector stores the state (ascending or descending) of each column
protected Integer one = new Integer(1);
protected Integer minusOne = new Integer(-1);
public SortTableModel() {
super();
ascendCol = new Vector();
public SortTableModel(Vector vec) {
super(vec);
ascendCol = new Vector();
public SortTableModel(Vector vec, Vector vec2, int numberOfColumns) {
super(vec, vec2);
ascendCol = new Vector();
setSortOrder(numberOfColumns);
This method is the implementation of the Comparator interface.
It is used for sorting the rows
public int compare(Object v1, Object v2) {
// the comparison is between 2 vectors, each representing a row
// the comparison is done between 2 objects from the different rows that are in the column that is being sorted
int ascending = ((Integer)ascendCol.get(currCol)).intValue();
if (v1 == null && v2 == null) {
return 0;
} else if (v2 == null) { // Define null less than everything.
return 1 * ascending;
} else if (v1 == null) {
return -1 * ascending;
Object o1 = ((Vector)v1).get(currCol);
Object o2 = ((Vector)v2).get(currCol);
// If both values are null, return 0.
if (o1 == null && o2 == null) {
return 0;
} else if (o2 == null) { // Define null less than everything.
return 1 * ascending;
} else if (o1 == null) {
return -1 * ascending;
if (o1 instanceof Number && o2 instanceof Number) {
Number n1 = (Number)o1;
double d1 = n1.doubleValue();
Number n2 = (Number)o2;
double d2 = n2.doubleValue();
if (d1 == d2) {
return 0;
} else if (d1 > d2) {
return 1 * ascending;
} else {
return -1 * ascending;
} else if (o1 instanceof Boolean && o2 instanceof Boolean) {
Boolean bool1 = (Boolean)o1;
boolean b1 = bool1.booleanValue();
Boolean bool2 = (Boolean)o2;
boolean b2 = bool2.booleanValue();
if (b1 == b2) {
return 0;
} else if (b1) {
return 1 * ascending;
} else {
return -1 * ascending;
} else {
// default case
if (o1 instanceof Comparable && o2 instanceof Comparable) {
Comparable c1 = (Comparable)o1;
Comparable c2 = (Comparable)o2; // superflous cast, no need for it!
try {
return c1.compareTo(c2) * ascending;
} catch (ClassCastException cce) {
// forget it... we'll deal with them like 2 normal objects below.
String s1 = o1.toString();
String s2 = o2.toString();
return s1.compareTo(s2) * ascending;
This method sorts the rows using Java's Collections class.
After sorting, it changes the state of the column -
if the column was ascending, its new state is descending, and vice versa.
public void sort() {
Collections.sort(dataVector, this);
Integer val = (Integer)ascendCol.get(currCol);
ascendCol.remove(currCol);
if (val.equals(one)) // change the state of the column
ascendCol.add(currCol, minusOne);
else
ascendCol.add(currCol, one);
public void sortByColumn(int column) {
this.currCol = column;
sort();
public void setSortOrder(int numberOfColumns) {
for (int i = 0; i < numberOfColumns; i++) {
ascendCol.add(one); -

Sorting of columns in report with values from lookup table (LOV)
Hi,
I have a report where I looku the values using a number of LOVs. I'd like to enable sorting on those columns in the report whihc works BUT the report get's sorted on the numric looku pvalue instead of the description for example COUNTRY_ID instead of COUNTRY_DESC.
I have played around with the function APEX_ITEM.ITEM_TET_FROM_LOV in my SQL query:
select ID, NAME,
APEX_ITEM.TEXT_FROM_LOV(COUNTRY_ID, 'COUNTRY_LOOKUP') COUNTRY,
from VAR
But I get the following error:
report error:
ORA-06550: line 1, column 13:
PLS-00103: Encountered the symbol "COLLECT" when expecting one of the following:
:= . ( @ % ;
ORA-06550: line 1, column 82:
PLS-00103: Encountered the symbol ";" when expecting one of the following:
. ( , % from
So I am thinking that I am doing something very wrong? Is there another way to accomplish this?
Andyyou need to use htmldb_item.text_from_lov in your query.
this will then deocde the key value to the description within the query itself and therefore allow you to do your sorting. -
Sorting a column does not result in distinct values on Dashboard prompts
Hi,
We have a period column, the records of which are 'JAN-02' , "FEB-02"...."DEC-09". We need sort this column in descending order in Dashboard Prompts. We have another column "Date", which has been used to sort the period column. To achieve this in descending order, we have converted Show Results from “All Values” to “SQL Results” in dashboard prmpts, then entered the below sql.
SELECT "CODE COMBINATIONS"."LINE AC PERIOD" FROM INVOICE_PAYMENTS
order by "CODE COMBINATIONS"."LINE AC DATE" desc
The above sql resulted in non-distinct values as below. Using distinct in the above sql throws syntax error.
Period
JAN-09
JAN-09
JAN-09
FEB-09
FEB-09
How do we get distinct values and in descending order??
Thanks and appreciate any ideas
SuryaGo to advanced tab and check "Use distinct clause" that will fire a distinct to the query.
In the rpd month logical column , there is an option called sort order in the general properties and you need to specify the date column if you need to sort it based on the date column and in the Answers you can simply enable Descending sort order on the same column. That should take care of it
Hope it helps
Thanks

Query contains double value - seems cache problem
Hi experts,
in a Query (integrated planning) based on an Aggregationlevel based on a Multicube.
The Multicube contains an Realtime InfoProvider to store planning data and a normal InfoProvider to show actual values.
The load of actual values to the InfoProvider can be executed several times a month via ProcessChain -
it´s a full load so the data loaded before will be deleted during the month in order to save the new monthly dataload.
In the Query there were double values displayed for actual data after several loads during the month -
but in the acutal InfoProvider only a single value is stored!
It seems to be a buffer problem, since a deletion of all system buffers solves the problem - but this is not the way to handle the problem in productive area.
How can the problem be solved?
Setting of Planbufferquery of acutal data InfoProvider to not using Cache doesn't help.
Thank you!
AngieHi,
there is no data stored in acutal cube and the query column is restricted to actual cube.
And actual cube only contains the value once, but the query can display the double value.
If all buffers are reset, the query shows correct value - but this is not the way to handle the problem.
What changes need to be made?
Is there a setting in query cache or planningbuffer query cache or some other setting that can fix the problem?
Best regards,
Angie -
Return the rows of the table where a column contains a specific value first

For Example:

If you store your "top" countries in a table you can then simply do something like...

Sorting based on a specific value in Columns
Hi All,
Crystal 2008 version I have. And we are connecting to BW queries as source.
In a crosstab, I want to sort my row values based on a column value.
For example, in rows I have an element with three values . In column I have only one element(month), with couple of month values. My requirement is to sort rows based on a specific month (Mar'09 for example).
.....................Jan'09......Feb'09.....Mar'09
ABC...............10.............323...........33....
XYZ...............32..............33............11....
FGH...............5................34.............55...
But when I try to sort based on the Month, I can not select a specific value(mar'09). And it sorts based on the total value (sum of all months).
How can I achieve this problem?
Thanks
OzanFor {Sort Value}, if you wanted to sort on the Jan column, then substitute the field name that your example shows as 10 in row ABC. For {row value}, substitute the field name that is used in the first column (ABC in the example).
In other words, take the value that you want to sort on, and put it in front of the value currently displaying as the row header. Then, sort on the results.
The purpose of the "000000000.00" is to make the length of the number, when converted to string, a consistent size. This is needed (a) so you know how many characters to strip off when displaying the row value, and (b) so the records don't sort as 1, 12, 2, 234, 235423, 25, 3, ...

Sql query slowness due to rank and columns with null values:
Sql query slowness due to rank and columns with null values:
I have the following table in database with around 10 millions records:
Declaration:
create table PropertyOwners (
[Key] int not null primary key,
PropertyKey int not null,
BoughtDate DateTime,
OwnerKey int null,
GroupKey int null
go
[Key] is primary key and combination of PropertyKey, BoughtDate, OwnerKey and GroupKey is unique.
With the following index:
CREATE NONCLUSTERED INDEX [IX_PropertyOwners] ON [dbo].[PropertyOwners]
[PropertyKey] ASC,
[BoughtDate] DESC,
[OwnerKey] DESC,
[GroupKey] DESC
go
Description of the case:
For single BoughtDate one property can belong to multiple owners or single group, for single record there can either be OwnerKey or GroupKey but not both so one of them will be null for each record. I am trying to retrieve the data from the table using
following query for the OwnerKey. If there are same property rows for owners and group at the same time than the rows having OwnerKey with be preferred, that is why I am using "OwnerKey desc" in Rank function.
declare @ownerKey int = 40000
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from (
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
) as result
where result.[Rank]=1 and result.[OwnerKey]=@ownerKey
It is taking 2-3 seconds to get the records which is too slow, similar time it is taking as I try to get the records using the GroupKey. But when I tried to get the records for the PropertyKey with the same query, it is executing in 10 milliseconds.
May be the slowness is due to as OwnerKey/GroupKey in the table can be null and sql server in unable to index it. I have also tried to use the Indexed view to pre ranked them but I can't use it in my query as Rank function is not supported in indexed
view.
Please note this table is updated once a day and using Sql Server 2008 R2. Any help will be greatly appreciated.create table #result (PropertyKey int not null, BoughtDate datetime, OwnerKey int null, GroupKey int null, [Rank] int not null)Create index idx ON #result(OwnerKey ,rnk)
insert into #result(PropertyKey, BoughtDate, OwnerKey, GroupKey, [Rank])
select PropertyKey, BoughtDate, OwnerKey, GroupKey,
RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
from PropertyOwners
go
declare @ownerKey int = 1
select PropertyKey, BoughtDate, OwnerKey, GroupKey
from #result as result
where result.[Rank]=1
and result.[OwnerKey]=@ownerKey
go

When you prepare your fieldcatalog check the column of the output itab for its contents, e.g.:
" Itab GT_FCAT contains fieldcatalog.
" Itab GT_OUTTAB contains ALV list data.
" Condition: column "MY_COLUMN" should contain at least single value > 0
LOOP AT gt_outtab TRANSPORTING NO FIELDS
WHERE ( my_column > 0 ).
EXIT.
ENDLOOP.
IF ( syst-subrc NE 0 ). " Column "MY_COLUMN" contains no value > 0, then hide column
READ TABLE gt_fcat INTO ls_fcat
WITH KEY fieldname = 'MY_COLUMN'.
IF ( syst-subrc = 0 ).
ls_fcat-no_out = 'X'. " not displayed, but visible in layout
ls_fcat-tech = 'X'. " not displayed, not available in layout
MODIFY GT_FCAT FROM ls_fcat INDEX syst-tabix.
