I am trying to hide a row in BIRT when a specific value equals a string. It works when the value equals something like 3 or (this_is_the_value) but it does not work when the value equals something like (this is the value) -> a value in the database with multiple words with spaces between them. How do I build the expression that hides the row when a value equals (this is the value) instead of (this_is_the_value)
Any help would be appreciated..

You have to enclose your value with quotes "this is the value" and use the double equals sign == to compare it to your row.
By the way, you can hide/show a visual text parameter in an expression like this:
!params[NAME_ID].value

I have a column that contains either letters or numbers. I want to add a column identifying whether each cell contains a letter or a number. The problem is that there are thousands of records in this particular database.
I tried the following syntax:
= Table.AddColumn(Source, "Column2", each if [Column1] is number then "Number" else "Letters")
My problem is that when I enter this, it returns everything as "Letter" because it looks at the column type instead of the actual value in the cell. This remains the case even when I change the column type from Text to General. Either way, it still produces "Letter" as it automatically assigns text as the data type since the column contains both text and numbers.
Use this expression:
= Table.AddColumn(Source, "Column2", each if List.Contains({"0".."9"}, Text.Start([Column1], 1)) then "Numbers" else "Letters")
Note: It would have been smart to add sample data to your question so I wouldn't have to guess what your data actually looks like!
Add column, custom column with
= try if Value.Is(Number.From([Column1]), type number) then "number" else "not" otherwise "not"
Peter's method works if the choice is AAA/111 but this one tests for A11 and 1BC as well
How can I filter a recordset by comparing two fields?
For a given ADO Recordset with n fields (Field1, Field2,...,Fieldn)
I used to filter a field against a value:
rs.Filter = "Field1 = 'something'"
But what I need to do is something like this:
rs.Filter = "Field1 = Field2"
Is that possible?
The criteria string is made up of clauses in the form FieldName-Operator-Value
Value is the value with which you will compare the field values (for example, 'Smith', #8/24/95#, 12.345, or $50.00). Use single quotes with strings and pound signs (#) with dates. For numbers, you can use decimal points, dollar signs, and scientific notation. If Operator is LIKE, Value can use wildcards. Only the asterisk (*) and percent sign (%) wild cards are allowed, and they must be the last character in the string. Value cannot be null.
This suggests that comparing fields to each other is not supported. Value must be a literal.
I would like to filter a specific value as well as blank values.
Example: Filter if the value is "VALUE" or ""
I tried this:
=filter({Summation!E2:K},match(Summation!D2:D,{$B$1,""},false))
And also tried this:
=filter({Summation!E2:K},or(match(Summation!D2:D,{$B$1},false),isblank(Summation!D2:D)))
But non of these work. How do I match for blank values. I want all blank values as well as those with the value B1.
You could use something like =QUERY(B1:K,"Select * where B='' and B='VALUE'",0)
That selects all data in the range B1:K where column B is blank (B='') AND where B is equal to VALUE (B='VALUE').
Replace B with whatever column contains the value you're trying to find.
I have a grid on a form that displays some columns from a dbf table and a textbox.
I want to search the value displayed in the textbox over all columns from a dbf table. Some fields are numeric and other are character
If I want to find a number, should search all record that contain that number in all columns, no matter the column type.
If I want to search a substring should give me all record that contain that substring.
SET FILTER TO ALLTRIM(ThisForm.Text1.Value) $Content or ALLTRIM(val(ThisForm.Text1.Value)) $registrationNumber or ALLTRIM(ThisForm.Text1.Value) $holderNo
Your approach with the "$" wildcard "contains" approach appears to be ok. However, your attempt via allt( val( )) would fail as you cant trim a numeric value, it would have to be pre-converted to a string.
Now, that said, you could shorten your query by just doing a $ against a concatenation of ALL columns something like (assuming your registration number is a numeric field)...
set filter to ALLTRIM(ThisForm.Text1.Value) ;
$ ( Content +"," +str(registrationNumber) +," + holderNo )
if you have dates or date/time fields you could do DTOC( dateField ) or TTOC( dateTimeField). So, by building a single string of all values, you dont have to explicitly repeat the OR condition repeatedly.
You could do something like:
select curGrid
scan
lcRow = transform(field1) + transform(field2) ... + transform(lastfield)
if lcSearchValue $ lcRow
DoWhatever()
endif
endscan
This leverages the fact that transform() will give a string representation of any data type.
I would like to know whats the XPath equivalent to SQL In query. Basically in sql i can do this:
select * from tbl1 where Id in (1,2,3,4)
so i want something similar in XPath/Xsl:
i.e.
//*[#id= IN('51417','1121','111')]
Please advice
(In XPath 2,) the = operator always works like in.
I.e. you can use
//*[#id = ('51417','1121','111')]
A solution is to write out the options as separate conditions:
//*[(#id = '51417') or (#id = '1121') or (#id = '111')]
Another, slightly less verbose solution that looks a bit like a hack, though, would be to use the contains function:
//*[contains('-51417-1121-111-', concat('-', #id, '-'))]
Literally, this means you're checking whether the value of the id attribute (preceeded and succeeded by a delimiter character) is a substring of -51417-1121-111-. Note that I am using a hyphen (-) as a delimiter of the allowable values; you can replace that with any character that will not appear in the id attribute.
