I am trying to use a cell as a parameter in Excel powerquery. The query works without this, but I have to manually input the values, which I need to constantly change them in the query in other to get the results that I want.
Query (Advanced Editor):
let
Criteria01 = Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{0},
Criteria02 = Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{1},
Criteria03 = Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{2},
Source = Sql.Database("SERVERNAMEHERE", "DATABASENAMEHERE", [Query="SELECT DISTINCT [...........] AND (TABLEPREF.COLUMNHERE like '%MANUALVALUE01%' OR#(lf)TABLEPREF.COLUMNHERE like '%MANUALVALUE02%' OR#(lf)TABLEPREF.COLUMNHERE like '%MANUALVALUE03%' OR#(lf)TABLEPREF.COLUMNHERE like Criteria01)#(lf)#(lf)#(lf)order by 1 asc"])
in
Source
"Servers" is the table name and "ServerSearch" is the column header. If I check the step for Criteria01/etc it will show me the correct value of that table that I need to use.
Original query done in Sql-Server. I have no problems when running the query with only LIKE '%MANUALVALUES%' lines.
My main goal is to automatically get N values of "MANUALVALUES" from a table in a sheet, which will be used as an input for comparing WHERE TABLEPREF.COLUMNHERE like '%VALUEHERE%'. I must use this and I can't get the whole table/database because there are way too many results besides the ones that I want.
However for test purposes at this moment, I am trying to use only 1-3 values, the first 3 of this table (Criteria{0}{1}{2} in the query above). However, if I try to do something like TABLEPREF.COLUMNHERE like Criteria01 I get the following error:
DataSource.Error: Microsoft SQL: Invalid column name 'Criteria01'.
Details:
DataSourceKind=SQL
DataSourcePath=dalsql390;itdw
Message=Invalid column name 'Criteria01'.
Number=207
Class=16
So my questions are:
I am getting the table cell value by the right way? Meaning:
Excel.CurrentWorkbook(){[Name="Servers"]}[Content][ServerSearch]{0}.
How do I refer this value in my query? Since the way that I wrote
that query bought me that error.
Also please note that if change TABLEPREF.COLUMNHERE like
Criteria01 to CHG1.CI_Name like "Criteria01" I get the
following error:
Expression.SyntaxError: Token Comma expected.
After fixed 1 and 2, how can I use this dynamically? For
example, instead of getting values of index 1 2 3, what if I want to
use a whole table? I know that using
Excel.CurrentWorkbook(){[Name="Servers"]}[Content] will bring me the whole table of values (1 column, unknown number of rows), but
how do I use this table content 1 by 1 in my query?
That will get the value, but you can't refer to steps inside of text values by putting the step name inside of it.
You have a couple options for doing this dynamically.
Use Value.NativeQuery to create a parameterized query where you can pass in other values as parameters. For example, Value.NativeQuery(Sql.Database("SERVERNAMEHERE", "DATABASENAMEHERE"), "select #a, #b", [a = 1, b = "x"]) will return the table [1, x]. You can put in the step name in the record value to pass that it (e.g. replace "x" with Criteria01).
Add the text values directly in the query field, e.g. [Query = "select " & Criteria01 ";"]. This is highly discouraged since this can lead to SQL injection issues.
For the third question, it depends what you want to do with the list of values. At some point you will likely need List.Accumulate to turn them all into a single text value which can be placed in the query value, and maybe to turn them into a record to place into the parameters value.

I've been tasked with creating a report for my company. The report is generated from the results returned by the Stored Procedure spGenerateReport, which has multiple filters.
Inside the SP, this is how the filter is expected to work:
SELECT * FROM MyTable WHERE column1 IN (
'filters', 'for', 'this', 'report'
)
Entering the code above yields ~30000 rows in 9s. However, I want to be able to change my SP's filter by passing it a single argument (since I may use 1 or 2 or n filters), like so:
spGenerateReport 'Filters,for,this,report'
For this I have the User-Created Function fnSplitString (yes, I do know that there is a STRING_SPLIT function but I can't use it due to a lower compatibility level of my database) which splits a single string into a table, like so:
SELECT splitData FROM fnSplitString('Filters,for,this,report')
Returns:
splitData
------
Filters
for
this
report
Thus the final code in my SP is:
SELECT * FROM MyTable WHERE column1 IN (
SELECT * FROM fnSplitString('Filters,for,this,report')
)
However, this instead yields ~10000 rows in 60s. The time taken to complete this SP is weird but isn't too much of a problem, however nearly a quarter of my rows disappearing into the void certainly is. The results only have rows from the first couple filters (for example, 'Filters' and 'for'; if I change the order of the arguments (e.g.: fnSplitString('report,for,Filters,this')), I get a different number of rows, and only from filters 'report', 'for', 'Filters'! I don't understand why using the function returns different results than those obtained when using the literal strings. Is there some inside gimmick that I'm not aware of?
PS - I'm sorry in advance for being bad at explaining myself, and for any grammar mistakes
You should definitely be getting the same results with both techniques. Something is wrong.
You havent posted the fnSplitString code but I suspect fnSplitString is not outputting the last string in the list, or maybe the last string in the list is being truncated before it reaches fnSplitString so that no matches are found.
e.g. if the parameter going into your spGenerateReport stored procedure is varchar(20) then what will reach the function is 'Filters,for,this,rep' with the last bit truncated.
SSRS, for example, will truncate strings that are being passed into an SP instead of warning you with an error message
I just created 2 cross table using wizard function of Telerik Standalone report designer tool
since ISCED 5 has values for private and public its showing properly
using same query I created second cross tab and
but since ISCED 6 table doesnt have values for "public" section its showing like this
how to show as zero for public section 2nd cross tab (when no values for specific row)
You should modify the value of the field using an expression to evaluate your condition.
Select the textbox containing the data corresponding to the column you like to format when the value is null.
In the property pan on the right select "Value"
Write in there your expression, it should be something like this:
=Iif(Fields.MyField IS Null,"0",Fields.MyField)
You should also consider if the value instead of null is empty and eventually cover this case in the expression if applicable.
= Iif(Fields.MyField IS Null OR Fields.MyField = "", "0", Fields.MyField)
More information on conditional formatting can be found here.
Let us know if this works for you.
I'm trying to create a field (calculation result) in FileMaker Pro 13 that will return the number of times a specific value is selected in a specific field.
For Example:
Say you have Table 1. Table 1 only has 1 field named Field 1. Field 1 is a drop down list field with the options "A","B", & "C". The following data is from the records of Table 1 using the field, Field 1:
Record 1: Table 1::Field 1 = "A"
Record 2: Table 1::Field 1 = "A"
Record 3: Table 1::Field 1 = "B"
Record 4: Table 1::Field 1 = "C"
What I want is a counter that searches across the records for table one and finds how many times a certain option is selected. For example, I want to know how many times "A" was selected in Field 1 and it would return "2".
What I have tried to do so far is the following but it hasn't worked out so hot (returns "?"):
ExecuteSQL(
"SELECT Field 1
FROM Table 1
WHERE Field 1 = 'A'"
;"";"")
Any suggestions for a correct SQL script?
The correct version of your Execute
ExecuteSQL(
"SELECT Count(\"Field 1\")
FROM \"Table 1\"
WHERE \"Field 1\" = ?"
;"";"";"A")
When you use ExecuteSQL, you're passing a string into FileMaker's function and then behind the scenes FileMaker uses that string and the various other pieces you give it to perform the action.
If you have a space in your field or table name, e.g. Field 1, FileMaker thinks you mean "Select a field name Field and a field named 1. You need to quote the field name if it contains spaces or special characters, but you can't use just regular double quotes because that would end the string.
The way to fix it is what I did above; escape the double quotes around the field or table name.
Also, the ? and the "A" at the bottom allows you to pass data into the query, i.e. parameterizing the query. This means you could do a loop where each iteration of the loop you pass in a different value where I have "A". E.g. You could do this:
ExecuteSQL(
"SELECT Count(\"Field 1\")
FROM \"Table 1\"
WHERE \"Field 1\" = ?"
;"";""; Table 1::Search Field)
or
ExecuteSQL(
"SELECT Count(\"Field 1\")
FROM \"Table 1\"
WHERE \"Field 1\" = ?"
;"";"";$searchValue)
Be careful though, ExecuteSQL doesn't cache records that it pulls if you're in a server/client environment so this calculation could get pretty sluggish if you have a lot of records in the table, you're going over the wan, or both. I would suggest trying to get the count a different way.
Select count(*) from Table1 where Field1='A'
I have a report in 2005 SSRS which I want to add a parameter to. The parameter would be comprised of a group of zip codes, but be selected as a single item in the list.
For example, I would like to have 5 zip codes as one selection in the list and 3 for another, etc:
Select 11111,22222,33333,44444,55555,66666 AS Boondock
Select 77777,88888,99999 AS Timbuck
Select Zip Codes NOT IN (11111-99999) AS Everything Else
So my selections in the dropdown would be:
Boondock
Timbuck
Everything Else
Can anyone help me with how I should go about creating this parameter?
Create a simple string parameter to present to the user. Let's call it ZipCodeSet.
Create a dataset that examines the #ZipCodeSet parameter and returns the appropriate list of zip codes. Call it ZipCodeSelection.
Create an internal multivaue parameter that uses ZipCodeSelection as both its Available Values and Default Values. Call it SelectedZipCodes.
Use SelectedZipCodes in your report's datasets.
The easiest solution here would probably to use a Calculated Field on your dataset, called LocationDescription, for example:
=SWITCH(Fields!ZipCode >= 11111 and Fields!ZipCode <= 66666, "Boondock", Fields!ZipCode >= 77777 and Fields!ZipCode <= 99999, "Timbuck",True, "Everywhere Else")
The lone true statement at the end is due to the SWITCH expression reading left-to-right and exiting once it evaluates one of the switches as TRUE. This way for each of the items in your table of ZipCodes you will always end up with a TRUE result.
I assume you're evaluating a range of ZipCodes, and not exact values of 11111,22222, and so on? If so, the switch will have more values. A sample of your data would help if you want an exact answer.
Once you have built your Calculated Field, you can then set up a Parameter (called #LocationParameter) with available values based on a query of your LocationDescription field, then just filter your dataset using:
Expression:
= Fields!LocationDescription
Operator: =
Value:
#LocationParameter
(if you want multiple selections on your parameter, change the operator to IN)
Hope that helps.
I found a weird problem with MySQL select statement having "IN" in where clause:
I am trying this query:
SELECT ads.*
FROM advertisement_urls ads
WHERE ad_pool_id = 5
AND status = 1
AND ads.id = 23
AND 3 NOT IN (hide_from_publishers)
ORDER BY rank desc
In above SQL hide_from_publishers is a column of advertisement_urls table, with values as comma separated integers, e.g. 4,2 or 2,7,3 etc.
As a result, if hide_from_publishers contains same above two values, it should return only record for "4,2" but it returns both records
Now, if I change the value of hide_for_columns for second set to 3,2,7 and run the query again, it will return single record which is correct output.
Instead of hide_from_publishers if I use direct values there, i.e. (2,7,3) it does recognize and returns single record.
Any thoughts about this strange problem or am I doing something wrong?
There is a difference between the tuple (1, 2, 3) and the string "1, 2, 3". The former is three values, the latter is a single string value that just happens to look like three values to human eyes. As far as the DBMS is concerned, it's still a single value.
If you want more than one value associated with a record, you shouldn't be storing it as a comma-separated value within a single field, you should store it in another table and join it. That way the data remains structured and you can use it as part of a query.
You need to treat the comma-delimited hide_from_publishers column as a string. You can use the LOCATE function to determine if your value exists in the string.
Note that I've added leading and trailing commas to both strings so that a search for "3" doesn't accidentally match "13".
select ads.*
from advertisement_urls ads
where ad_pool_id = 5
and status = 1
and ads.id = 23
and locate(',3,', ','+hide_from_publishers+',') = 0
order by rank desc
You need to split the string of values into separate values. See this SO question...
