I need to set up a query that returns only the values that would match a pattern {Any character & digit}
I've tried setting up a filter criteria to ' %_
[0-9] but it doesn't work...I want to exclude any results that have two letters as the first two characters of a value.
Thanks!
In the presentation column, you can use the OBIEE - Evaluate - Embedded DB Functions in a formula.
For example (not the exact regex you are looking for but you get the point):

I need to search an oracle table column for multiple word strings in cognos oracle query.
For example:
If Focus parameter returns multiple values as below
TRAINING
OMNIA
COUNTER
PROGRAM
And I need to search project.proj_name column like '%TRAINING%' or '%OMNIA%' or '%COUNTER%' or '%PROGRAM%'
I am trying below but I know it does only single value match not multiple. I want to know how to achieve multiple value match here.
'-99' in (#promptmany('Focus', 'string','-99')#) OR REGEXP_LIKE(proj_name, #promptmany('Focus', 'string','-99')#))
Working from Cognos Paul's solution to use output from promptmany as a table:
Assuming your query is named Q1...
Add a query. (Q2)
Add a SQL object to that query.
Set the Data source property for the SQL object.
Change the SQL Syntax property to IBM Cognos.
Define the query as
SELECT
parameterValue
FROM (VALUES
(#join('),(',split(',',promptmany('Scenarios','string',sq('N/A'))))#)
) query(parameterValue)
(change the names for your own use case)
Add a query. (Q3)
Add a join to the new query.
Add Q1 and Q2 to the empty boxes for the join leading to Q3.
Set the join as
[Q1].[proj_name] like '%' || [Q2].[parameterValue] || '%'
Add the required data items to Q3.
Since two keywords (from your parameter -> Q2) could be found in a single value (in Q1), you'll likely end up with duplicate rows. Cognos will probably handle this with its default aggregations, but keep a lookout.
Be careful with this. The new query (Q2) will probably be joined on the Cognos server, not on the database server. Be sure you have sufficient filters leading into this structure so Cognos is not trying to process your entire database.
This worked for me with SQL Server. I don't have an Oracle database to test against, but using IBM Cognos as the SQL Syntax should handle that.
To use REGEXP_LIKE to solve this problem, you'll need to get the second argument correct. I can't see any reason to see the error message ORA-00996: the concatenate operator is ||, not |, but I'm not working with your code in your system.
You don't specify which version of Cognos, or even which Cognos product, you are using. I'll assume Cognos Analytics 11.1.7.
To determine what Cognos Analytics is doing with your macro, create a very simple query with one item from the database (preferably from a very small table) and another data item that contains the macro. So the data item expression is:
#sq(join('|',split(',',promptmany('Focus','string','-99'))))#
When you run this, you may not be prompted. You'll see the value is -99. So to test this we'll need to remove the default so that the prompt becomes required.
#sq(join('|',split(',',promptmany('Focus','string'))))#
Be sure to enter more than one value when you test.
In my environment, the parameter returns a value that is my values surrounded by quotes (') and delimited by semicolons (;). So my tests produced the following:
expression
value
#sq(promptmany('Focus','string'))#
'PROGRAM';'COUNTER';'TRAINING'
#sq(join('|',split(',',promptmany('Focus','string'))))#
'PROGRAM';'COUNTER';'TRAINING'
#sq(join('|',split(';',promptmany('Focus','string'))))#
'PROGRAM'|'COUNTER'|'TRAINING'
replace(#sq(join('|',split(';',promptmany('Focus','string'))))#, '''', '')
PROGRAM|COUNTER|TRAINING
Your mileage may vary.
At this point, you know which macro to use in the REGEXP_LIKE function.
This question is related with this question. However, in that question I made some wrong assumptions...
I have a string that contains a SQL query, with or without one or more parameters, where each parameter has a "&" (ampersand sign) as prefix.
Now I want to extract all parameters, load them into a table in excel where the user can enter the values for each parameter.
Then I need to use these values as a replacement for the variables in the SQL query so I can run the query...
The problem I am facing is that extracting (and therefore also replacing) the parameter names is not that straight forward, because the parameters are not always surrounded with spaces (as I assumed in my previous question)
See following examples
Select * from TableA where ID=&id;
Select * from TableA where (ID<&ID1 and ID>=&ID2);
Select * from TableA where ID = &id ;
So, two parts of my question:
How can I extract all parameters
How can I replace all parameters using another table where the replacements are defined (see also my previous question)
A full solution for this would require getting into details of how your data is structured and would potentially be covering a lot of topics. Since you already covered one way to do a mass find/replace (which there are a variety of ways to accomplish in Power Query), I'll just show you my ugly solution to extracting the parameters.
List.Transform
(
List.Select
(
Text.Split([YOUR TEXT HERE], " "), each Text.Contains(_,"&")
),
each List.Accumulate
(
{";",")"}, <--- LIST OF CHARACTERS TO CLEAN
"&" & Text.AfterDelimiter(_, "&"),
(String,Remove) => Text.Replace(String,Remove,"")
)
)
This is sort of convoluted, but here's the best I can explain what is going on.
The first key part is combining List.Select with Text.Split to extract all of the parameters from the string into a list. It's using a " " to separate the words in the list, and then filtering to words containing a "&", which in your second example means the list will contain "(ID<&ID1" and "ID>=&ID2);" at this point.
The second part is using Text.AfterDelimiter to extract the text that occurs after the "&" in our list of parameters, and List.Accumulate to "clean" any unwanted characters that would potentially be hanging on to the parameter. The list of characters you would want to clean has to be manually defined (I just put in ";" and ")" based on the sample data). We also manually re-append a "&" to the parameter, because Text.AfterDelimiter would have removed it.
The result of this is a List object of extracted parameters from any of the sample strings you provided. You can setup a query that takes a table of your SQL strings, applies this code in a custom column where [YOUR TEXT HERE] is the field containing your strings, then expand the lists that result and remove duplicates on them to get a unique list of all the parameters in your SQL strings.
I have an SSRS report that will be used in Dynamics 365 so I can't use SQL in the dataset to help here.
I have a product/version code column that is string mixing letters and numbers. For example:
FF8,
FF9,
FF10,
FFA
These are going in to a column header and form a column group which is also sorted by the code. The standard alphabetical sorting is giving this order:
FF10 - FF8 - FF9 - FFA
I'm happy to use a substring in my sort expression to remove a preceding product code but I would like the numbers in ascending numerical format followed by text versions alphabetically:
FF8 - FF9 - FF10 - FFA
I would add a calculated column to your dataset that strips the non-numeric characters and converts to a number. This would make it easier to sort
A formula like this might help
=System.Text.RegularExpressions.Regex.Replace(Fields!productcode.Value, "[^0-9]", "")
The ^ symbol means "not" so this Regex expression will remove all characters that are not in the range of 0 to 9 (i.e. all non-numeric characters)
According to this, Regex.Replace should be supported in CRM's sandboxed reports
You also could use expression like below in Sort
=switch(Fields!name.Value="FF10",3,Fields!name.Value="FF9",2,Fields!name.Value="FF8",1,Fields!name.Value="FFA",4)

I have an excel file with a table named 'Table1' in it. I have to perform 'Filter Table' activity in UiPath with the condition "column1 begins with '*my column'". But when I specify the value like this, the column is filtered for 'ends with' operation.
Here is the screenshot for my table-
Below is the screenshot for the steps I followed-
This has been answered many times on UiPath Forum
For example https://forum.uipath.com/t/filter-table-in-excel-data-tables/559/3
If you use *my value as the search / filter pattern, then it'd mean, anything in the beginning and must have my value in the end. So, it is being interpreted correctly as Ends With. If you want to have a Begins With filter, you should have your filter text followed by the wildcard, like - my value*.
Further, if you want to include wildcard as a literal in the search pattern, you'd need to escape that by enclosing it in brackets like [*]my value* - this'd search for text beginning with *my value.
MS Excel / VBA also supports Tilde ~ as an escape character in some cases.
In excel filters, '' represents any series of characters.
The issue in the above case is that the filter value in the condition already contains a ''. Because of this, system always reads it as '*My column' => '[any characters]My column'. i.e., value ends with 'My column'.
To resolve this issue, I have specified contains filter instead of Begins with as 'My column'.
I have also tried to escape '*'. But it threw excel exception.
In addition, you can not specify condition as "Column1 Like '*My column%'". This works file when you are adding filter to 'DataTable'(after performing 'ReadRange' activity). But in this case, you will retrieve all the records and then you will be filtering the columns. This will lead to performance issues if the the excel table is huge.
You can follow the syntax below to perform filter activities in an excel:
DataTableName.Select("[ColumnName]='Datawithwhichweneedtofilter’").CopytoDataTable()
In Oracle I try to find all the rows that contains some diacritics in one column. I used something like:
where regexp_like(name,'(Ă|Î|Ș|Ț|Â)','i');
The problem is that it also returns rows that contain the letters without diacritics (A,I,S,T). For example the clause above will return a row that contains "Adrian" as name.
How can I search only for diacritics?
Thank you
The way diacritics is handled in comparisons and when sorting is a property of the session that depends on the value of NLS_SORT. See Linguistic Sorting and String Searching
I think it may be caused by character conversion.
What do you get when you run the query?:
select 'ĂÎȘȚÂ' from dual
