Okay. Basically, I want to define a complex variable within a SQL statement and then define another variable as a "function" of the first. I've searched around and can find no indication of how I might accomplish this. I can always just copypaste the code, but that makes it SO messy! See my (erroneous) example below. true file is the first variable and location is the second.
select
true_file = RIGHT(url.FULL_PATH, CHARINDEX('/',REVERSE(url.FULL_PATH)) - 1),
location = RIGHT(url.FULL_PATH, LEN(url.FULL_PATH) - LEN(true_file) - 9)
from files f
join BBLEARN_cms_doc.dbo.XYF_URLS url
on url.FILE_ID = substring(f.file_name, 6, len(f.file_name) - 7)
where f.file_name like '/xid-%'
order by url.FULL_PATH;
But obviously, we get an "invalid column name" error when trying to run any functions on true_file. What's the best way to do this?

Long story short, I have a sql query pulling data from a database into a spreadsheet. I want to be able to change the Plant filter inside the query via Power Query, I have tried using a custom function and adding that into the query where the variable is set (see below)
Sql.Database("server", "database", [Query="DECLARE #FilterOnPlant AS varchar(3)#(lf)SET #FilterOnPlant = '" + filterOnPlant + "'#(lf)#(lf)SELECT
In doing this I keep getting the following error:
Expression.Error: We cannot apply operator + to types Text and Table.
Details:
Operator=+
Left=DECLARE #FilterOnPlant AS varchar(3)
SET #FilterOnPlant = '
Right=[Table]
I figure it has something to do with the '+' operator used but can't find an alternative.
I have tried using:
'&'
'+'
'and'
but they all yield the same error (with the exception of 'and' that error states that it's not being used in a logical statement which makes sense)
For further info:
The custom function to get the value I want is:
filterOnPlant = Excel.CurrentWorkbook(){[Name="Active_Plant"]}[Content]
The intention is to get the Value from a cell Named "Active_Plant"
EDIT:
after further testing I have found the issue lies with variable filterOnPlant, when I exchange that for a string value then the query works as expected. If anyone knows how I can get CELL().Value of a named range in power query would be super helpful
Solved!
In my filterOnPlant function I was missing {0}[Column1]
Original: filterOnPlant = Excel.CurrentWorkbook(){[Name="Active_Plant"]}[Content]
New (Working): filterOnPlant = Excel.CurrentWorkbook(){[Name="Active_Plant"]}[Content]{0}[Column1]
I am using a SQL notebook in Databricks/Spark community edition
%python
education_DF = sqlContext.sql('select * from global_temp.population_Globaltmp_view where `Education` = "2YD"')
display(education_DF)
The above code cell works fine and retrieves the desired rows from the view.
However the following code cell gives an error.
I am supbstituting the hard-coded value "2YD" in the WHERE clause, with a variable call education_choice that contains the same value.
It seems that I am not using variables correctly in SQL. How would I make this work?
%python
education_DF = sqlContext.sql('select * from global_temp.population_Globaltmp_view where `Education` = education_choice')
display(education_DF)
(This is the error)
org.apache.spark.sql.AnalysisException: cannot resolve '`education_choice`' given input columns: [global_temp.population_globaltmp_view.Salary, global_temp.population_globaltmp_view.Address, global_temp.population_globaltmp_view.Race, global_temp.population_globaltmp_view.MiddleI, global_temp.population_globaltmp_view.Education, global_temp.population_globaltmp_view.HairColor, global_temp.population_globaltmp_view.Age, global_temp.population_globaltmp_view.FullName, global_temp.population_globaltmp_view.City, global_temp.population_globaltmp_view.FirstName, global_temp.population_globaltmp_view.State, global_temp.population_globaltmp_view.LastName, global_temp.population_globaltmp_view.Height, global_temp.population_globaltmp_view.Fertility, global_temp.population_globaltmp_view.Employment, global_temp.population_globaltmp_view.Zip, global_temp.population_globaltmp_view.Weight, global_temp.population_globaltmp_view.Gender]; line 1 pos 72;
I tried the injection method suggested, but got a slightly different error this time. I included a screen shot of the relevant code cells. It seems that the education_choice "2YD" isn't being recognized as a literal but a field or something like that.
Shouldn't 2YD have quotes around it like "2YD"
If I hard code the WHERE clause like this: WHERE Education = "2YD" the queries works fine.
The image bellow is small but if you right click on it and "open in new tap, it is very readable.
*EDIT
You use the variable education_choice as a hardcoded string. Instead, you should inject the value of education_choice inside the SQL expression string like that.
*edit - wrap the variable with quoets.
%python
education_DF = sqlContext.sql('select * from global_temp.population_Globaltmp_view where `Education` = "{}"'.format(education_choice))
display(education_DF)
The following query (qryCurLotNewProducts) produces a data set that I want process further with another query (qryBNP_CFRecordset):
//qryCurLotNewProducts
SELECT tblNewProducts.*
FROM tblNewProducts INNER JOIN tblCurLot ON (tblCurLot.CatalogNum = tblNewProducts.CatalogNum) AND
(tblNewProducts.LotNum = tblCurLot.CurLot);
When I run this second query to list only the "CF" products found in the first query, I get the `Data type mismatch in criteria expression' error.
//qryBNP_CFRecordset
SELECT qryCurLotNewProducts.*, tblABCategory.UNSPSC, tblAmount.ProductSize
FROM tblAmount RIGHT JOIN (tblABCategory RIGHT JOIN qryCurLotNewProducts ON tblABCategory.ABCategory = qryCurLotNewProducts.ABCategory) ON tblAmount.Amount = qryCurLotNewProducts.Amount
WHERE (((qryCurLotNewProducts.CatalogNum) Like "A700-###CF") AND ((qryCurLotNewProducts.DateEntered) Between #1/1/2000# And #3/1/2020#))
ORDER BY qryCurLotNewProducts.CatalogNum, Abs(qryCurLotNewProducts.LotNum);
If I remove the CF from the search string (so "A700-###"), the query correctly outputs a list containing all items that contain that pattern:
If I use strings like "A700-####F" or "A700-###ZZ" or other combinations like that, I don't get an error but rather an empty results set.
Notably, "A700-001CF", "A700-002CF", etc all create the data type error. It seems there is something about the CF key combination that is causing trouble.
Has anybody else ever seen this issue? Do I need to use some kind of delimiter to tell SQL to not view CF as some kind of special switch?
Abs(qryCurLotNewProducts.LotNum) wont work with the values for Products ending in CF. Your LotNum-Column has a text-type.
Edit: Your LotNum-Column has a text-type as you can see in your first screenshot.
Trying to wrap my head around zoho creator, its not as simple as they make it out to be for building apps… I have an inventory database, and i have four fields that I call to fill a field called Inventory Number (Inv_Num1) –
First Name (First_Name)
Last Name (Last_Name)
Year (Year)
Number (Number)
I have a Custom Function script that I call through a Custom Action in the form report. What I am trying to do is upload a CSV file with 900 entries. Of course, not all of those have those values (first/last/number) so I need to bulk edit all of them. However when I do the bulk edit, the Inv_Num1 field is not updated with the new values. I use the custom action to populate the Inv_Num1 field with the values of the other 4 fields.
Heres is my script:
void onetime.UpdateInv()
{
for each Inventory_Record in Management
{
FN = Inventory_Record.First_Name.subString(0,1);
LN = Inventory_Record.Last_Name.subString(0,1);
YR = Inventory_Record.Year.subString(2,4);
NO = Inventory_Record.Number;
outputstr = FN + LN + YR + NO;
Inventory_Record.Inv_Num1 = outputstr;
}
}
I get this error back when I try to run this function
Error.
Error in executing UpdateInv workflow.
Error in executing For Each Record task.
Error in executing Set Variable task. Unable to update template variable FN.
Error evaluating STRING expression :
Even though there is a First Name for example, it still thinks there is none. This only happens on the fields I changed with Bulk Edit. If I do each one by hand, then the custom action works—but of course then the Inv_Num1 is already updated through my edit on success functions and makes the whole thing moot.
this may be one year late, you might have found the solution but just to highlight, the error u were facing was just due to the null value in first name.
you just have put a null check on each field and u r good to go.
you can generate the inv_number on the time of bulk uploading also by adding null check in the same code on and placing the code on Add> On Submt.( just the part inside the loop )
the Better option would be using a formula field, you just have to put this formula in that formula field and you'll get your inventory_number autogenerated , you can rename the formula_field to Inv Number or whaterver u want.
Since you are using substring directly in year Field, I am assuming the
year field as string.else you would have to user Year.tostring().substring(2,4) & instead of if(Year=="","",...) you have to put if(Year==null , null,...);
so here's the formula
if(First_Name=="","",First_Name.subString(0,1))+if(Last_Name =="","",Last_Name.subString(0,1)) + if(Year=="","",Year.subString(2,4)+Number
Let me know ur response if u implement this.
Without knowing the datatype its difficult to fix, but making the assumption that your Inventory_Record.number is a numeric data item you are adding a string to a number:
The "+" is used for string Concatenation - Joiner but it also adds two numbers together so think "a" + "b" = "ab" for strings but for numbers 1 + 2 = 3.
All good, but when you do "a" + 2 the system doesn't know whether to add or concatenate so gives an error.
I keep getting the same error: Missing Operator. I have looked over this code three times and cannot find it. Can someone with a keen eye please help?
WHERE ([Letter Status].[Letter_Status] = “Agreed” AND [Research].[Site] = 9)
OR ([Telephone Status].[Details]= “Agreed” AND [Research].[Site] = 9)
I'm not sure about that “”
Maybe is from this post, but change them to "" :
WHERE ([Letter Status].[Letter_Status] = "Agreed" AND [Research].[Site] = 9)
OR ([Telephone Status].[Details]= "Agreed" AND [Research].[Site] = 9)
Usually it is a misspelled table or field name, two spaces instead of just one, a space instead of "_", any missing letter or something like that.
Create a new query in MS Access and put the whole query in, then run it. The Access GUI most probably tells you more detailed what exactly is missing here.
