I have a PDI transformation that gets 3 fields from a result row:
SEARCH_VALUE
Asset
IP_V4_Address
The next hop is a table input that searches based on search value and returns one column value, something like abcd-1234.
SELECT DISTINCT p.txt_reqID FROM ...
Now, after my table input runs, the resulting stream only has 1 column (the txt_reqID). I'd like my output stream to have 4 columns - the original 3 + the new one from the table input. How do I do that?
Here is the transformation and the input row structure:
This is the table input setup:
I'm only able to access the txt_reqID field after the table input, I can't figure out how to tell it to pass the other 3 through.
You can achieve this by having Select values step after the Get rows from result step. Select Values is required to duplicate your SEARCH_VALUE as you need this field in both SELECT and in the WHERE clause and also it can be used to reorder the fields before table input.
In Table input you can use the query like
SELECT DISTINCT p.txt_reqId, ? as SearchValue, ? as Asset, ? as IPV4 address
FROM ... WHERE d.value like ?

I have some samples I need to take.
In order to create a good identifier/serial number for the samples, I want it to be a product of its characteristics.
For example, if the sample was taken from India and the temperature was 40 degrees then I would click dropdowns in the form to create those two entries and then a serial number would be spat out in the form "Ind40".
Assuming that your form is bound to a table, you can create a calculated column in the table that concatenates the values from other columns into a single value.
For instance, create a new column and give it a name (for example, SerialNbr). Then for Data Type select "Calculated". An expression builder window will appear:
Enter the columns you'd like to concatenate and separate them with &. Here is an example of how the expression could look:
Left([Country],3) & [Temperature]
This expression takes the first 3 chars from the Country column and combines it with the value from Temperature column to create the value in column SerialNbr. The calculated column will automatically update when values are entered into the other fields. I'd also suggest adding another value to the calculated expression to help avoid duplicates, such as date/time of submission.
I have a view, A, with 20 columns which forms my primary data. I have a table B which lists some of the columns from A and contains data I want to exclude from A.
For example table B will have 6 columns 2 of which are 'customer' and 'country' and contain the data 'HP' and 'America'. These columns exist in A. But I want to write a query that brings back data from A except where any rows that have a combination HP and America.
There are 6 columns and table B can have any combination of rows. Anywhere between 1 and all 6 rows could be filled in or there could be a row which has 5 columns filled in. Also another row with a different 5 columns filled in and so on.
I want to be prepared for any possible combination of the 6 rows and the query to search A for the combination and exclude any rows with that data from B.
I have tried this
SELECT *
FROM A T1
WHERE not EXISTS
(SELECT * FROM [dbo].[ExcludedItems] T2
WHere ReportNumber=1
AND
(
T1.job=ISNULL(T2.job,T1.job) and T1.CustomerName=ISNULL(T2.CustomerName,T1.CustomerName) and
T1.COUNTRY= ISNULL(T2.COUNTRY,T1.COUNTRY) and T1.CONTINENT=ISNULL(T2.CONTINENT,T1.CONTINENT) AND
T1.continer= ISNULL(T2.ContainerName, T1.continer) and T1.UnscheduledJob= ISNULL(T2.unscheduledJob, T1.UnscheduledJob) and
T1.[Price]= ISNULL(T2.Price, T1.Price) and
T1.[Haulage]= ISNULL(T2.[Haulage], T1.[Haulage]) and
T1.SiteAdress= ISNULL(T2.SiteAddress, T1.SiteAdress) and T1.Delta=ISNULL(T2.Delta, T1.Delta) and
T1.Cost= ISNULL(T2.Cost, T1.Cost)
)
)
The problem is the result set is not correct. I have tried with a smaller column sample and able to exclude the correct combination of Customer and Country but when I introduce a 3rd or 4th column combination I can eyeball the result set and immediately see its incorrect. Not sure if I have to use multiple NOT EXISTS for each possible combination, was hoping not to.
A constraint is A has to be a view not a table. Otherwise I would have used variables in some manner and wrapped the whole thing in a stored procedure.
Appreciate any help, fall back is to manually add to the code each time an item combination is supplied in B!
I have a table in tableau with say 4 columns (Say Employee ID, Name, Address, Email).
I want to provide the users an option to select single/multiple columns from a drop down list (assume in the drop down list we have columns headers, Customfield1, Customfield2.....,Customfield10) which would be added to the table as a separate columns.
Say for Instance if the user selects CustomField1, CustomField2, CustomField3 from the drop-down list then the table should have in total of 7 columns (4 Emp fields + 3 Custom Fields)
Though I stated a simple requirement, my idea was to extrapolate that to something complex.
I think some version of this could be done, albeit in a hacky way. What you're looking for is 'Dynamic Parameters.' They don't technically officially exist in the product, but can be created with the combination of parameter and calculated field.
Here is a link to a method on such creation.
The idea here would be to re-order columns in a custom manner. Each calculated field would have to have its own logic for which dimension it was to display when a user selected a parameter. (ie: With parameter selection A Column 1 goes to [Name] and Column 2 goes to [Address], and with parameter selection B Column 1 goes to [Address] and Column 2 goes to [Name].) The caveat here is that each potential layout would need to have the same number of columns - there is not a way to add columns dynamically. Consider that each column is represented here with a calculated field.
Good luck on it.
I am trying to sort the retrieved data in the result grid in MySQL Workbench.
E.g. with the query
SELECT * FROM deepmining.prediction
WHERE (search_id = 39 OR search_id = 41) AND lead = 10 AND lag = 10 ;
I get in the result grid, when I sort on the column scale and timeshift (sorting using the result grid UI, not modifying the SQL query):
Shouldn't the first two rows be:
instead, just as if I had appended ORDER BY timeshift, scale; to the SQL query?
Or does sort MySQL Workbench sorting on multiple columns, despite what the UI seems to indicate by the presence of an arrow on the columns scale and timeshift?
The sort order depends on the order how you clicked the headers. The first click is used for the primary sort, the second for the sorting within the primary and so on. See the following images:
Sorted by first clicking on last_name then first_name.
Sorted by first clicking on first_name then last_name.
I have a query with 3 parameters that a user should be able to define:
AND (ORION_SCHED.TRIP.DATE_TIME = '09/11/2012')
AND (ORION.CUST.COUNTRY = 'BE')
AND (ORION_SCHED.TRIP.ID_SHIFT ='1')
DATE_TIME should be a datepicker
COUNTRY dropdown with defined values
ID_SHIFT dropdown with defined values
I guess this isn't an issue?
The result of this query will return the dataset
My actual question: I want the result to be presented in this way
So always 3 blocks of data next to each other, the data of every block is the result of the query filtered down on the column TRUCK_ID (a sub-select of the returned dataset)
The empty cells per block are a nice to have, these are non-unique values per TRUCK_ID that I don't wish to be repeated on every line, but like I said a nice to have.
I would add a new column to the query that returned 1,2 or 3 (for each different TRUCK_ID. Then I would use 3 Tablix (one per column on your report) and filter the data by the new column you added on the query.
Then you just group on the TruckID on each tablix and play around with the format. It should work.
