I'm trying to make a row visible based on two parameters.
ParameterA is a string.
ParameterB is a string.
Dataset looks like this:
Product | Warehouse | Quantity
1000 | A | 100
1000 | B | 100
Subtotal | | 200
1001 | A | 200
1001 | B | 200
Subtotal | | 400
1002 | A | 500
Subtotal | | 500
Parameter A shows (2) or hides (1) the individual warehouse entries, just leaving the subtotal.
For Parameter B, it returns a 0 if there is only one warehouse with stock for a product, and a 1 if there is more than one warehouse with stock for that product.
For the 'subtotal rows', I would like it to show if Parameter A wants to hide the warehouse entries, but obviously make sure the row is visible if there is only one product for that warehouse. Otherwise, Product 1002 won't show with the 'hide individual warehouse entries' option.
My attempt looks like this:
=IIF(Parameters!ParameterA.Value = "2" & Parameters!ParameterB.Value = 1,True,False)
This generates the below error:
The Hidden expression for the tablix 'Tablix2' contains an error:
operation '&' is not defined for string "2" and type 'Object()'.
Any ideas how to get the desired result would be appreciated.
In VB.Net, '&' is used for concatinating two strings and for logical-AND operator we simply use 'and'..
These are two entirely different keywords.
Here, you are trying to use '&' for logical-And operation which causes the error. Correct expression should be like this:
=IIF(Parameters!ParameterA.Value = "2" AND Parameters!ParameterB.Value = 1,True,False)

2-column MySQL Table:
| id| class |
|---|---------|
| 1 | A,B |
| 2 | B,C,D |
| 3 | C,D,A,G |
| 4 | E,F,G |
| 5 | A,F,G |
| 6 | E,F,G,B |
Requirement is to generate a report/output which tells which individual CSV value of class column is in how many rows.
For example, A is present in 3 rows (with id 1,3,5), and C is present in 2 rows (with id 2,3), and G is in 4 rows (3,4,5,6) so the output report should be
A - 3
B - 3
C - 2
...
...
G - 4
Essentially, column id can be ignored.
The draft that I can think of - first all the values of class column need to picked, split on comma, then create a distinct list of each unique value (A,B,C...), and then count how many rows contain the unique value from that distinct list.
While I know basic SQL queries, this is way too complex for me. Am unable to match it with some CSV split function in MySQL. (Am new to SQL so don't know much).
An alternative approach I made it to work - Download class column values in a file, feed it to a perl script which will create a distinct array of A,B,C, then read the downloaded CSV file again foreach element in distinct array and increase the count, and finally publish the report. But this is in perl which will be a separate execution, while the client needs it in SQL report.
Help will be appreciated.
Thanks
You may try split-string-into-rows function to get distinct values and use COUNT function to find number of occurrences. Specifically check here
I'm having some problems with the data types of some tables.
For example, I have:
+-------+----------+-------------+----------+--------------+
| Code | Money1 | Money2 | Quantity | Total |
+-------+----------+-------------+----------+--------------+
| 10001 | 100.4334 | 200.3444332 | 100 | 50,432.74642 |
+-------+----------+-------------+----------+--------------+
But I only want 2 digits in each column. I know how to do it from the Table (choosing Number -> Standard -> 2 decimals), but when I compile the query that corresponds to that Table, it breaks again.
I think I have to put CLng(), CInt() and that stuff in the query. Where? In SELECT, FROM, TO?. Is that OK? How "Standard, 2 digits" is called in that nomenclature?
Use Round([Money1], 2) for your columns in the query or - if you are serious about rounding - the RoundMid function here:
GitHub VBA.Round
Then use:
Select
Code,
RoundMid([Money1], 2) As Money_1,
RoundMid([Money2], 2) As Money_2,
Quantity,
RoundMid([Total], 2) As Total2

I have a Table (T_agents) of agents each has a number of call in a field called NCH I want to create another field call NCHpercent that is the percentage of calls taken by that agent. So the formula is NCH/Total NCH.
So in the query builder I have the following and formula but it dosent work :(
NCHpercent: [NCH.T_agents] / ( SUM(SELECT [NCH.T_agents] FROM [T_agents]) )
What am I doing wrong ?
This would be easier if we could see the table structure as that impacts everything. However I hope I follow this correctly, but I imagine your table (T_agents) as something like:
+-------+-------------+------+
| ID | Agents | NCH |
+-------+-------------+------+
| 1 | agent_1 | 1 |
| 1 | agent_1 | 1 |
| 1 | agent_2 | 2 |
| 1 | agent_3 | 1 |
+-------+-------------+------+
Now assuming that is correct (and NCH is not a unique ID but a total number of calls then we can use a query like this to calculate percentage - note this is not stored in a table, this is just to display the percentage value in a query- I've also added the sum of the total in for the sake of it:
SELECT SUM([T_Agents].NCH) AS total_SUM, [T_agents].Agents, ((SUM(T_agents.NCH))/(select SUM(t_agents.NCH )from T_agents)*100) AS NCHPercent
FROM T_agents
GROUP BY [t_agents].Agents;
In my test the results would be:
2, agent_1, 40
2, agent_2, 40
1, agent_3, 20
However if I got this wrong and the NCH column is in fact
Ok. I just found the answer soing some trial an error. The answer is this code:
NCHperc: [AHT_Tenure].[Calls Handled]/(SELECT Sum(AHT_Tenure.[Calls Handled]) AS [SumaDeCalls Handled]
FROM AHT_Tenure)
By the way thank you guys. And actually the agents name dosent matter for this query since all I wanted was the percentage on each row.
I've been racking my brains for a while and I'm sure there is a simple solution to it, but for the life of me it's not obvious.
I want to query a database in MySQL Workbench to return a set of serial numbers for a given part number, which is of a fairly basic form:
Select serial_num as sn12345
from process
where part_number = 12345
Thus my output is
sn12345
---------------
0000001
0000002
etc
Now I have a number of part numbers I want to get the serial numbers of so that my output is like
sn12345 | sn12346 | sn12347 |
------------------------------------------
0000001 | 0000005 | 0000008 |
0000002 | 0000006 | 0000009 |
Assume that there are more columns than just these. However, I do not want to UNION the query as I want output in individual columns. Also, there may be different numbers of serial number entries for each part number, i.e 100 for one, but 1000 for a second, and 5 for a third, etc, so I'll probably have a lot of NULL entries.
Thanks in advance!
I have two related tables, results and userID.
results looks like this:
+----+--------+--------+
| ID | userID | result |
+----+--------+--------+
| 1 | abc | 124 |
| 2 | abc | 792 |
| 3 | def | 534 |
+----+--------+--------+
userID looks like this:
+----+--------+---------+
| id | userID | name |
+----+--------+---------+
| 1 | abc | Angela |
| 2 | def | Gerard |
| 3 | zxy | Enrico |
+----+--------+---------+
In results, the userID field is a lookup field; it stores userID.id but the combo box has userID.userID as its choices.
When I try to enter data into results by setting the userID combo box and entering a value for result, I get this error message:
You cannot add or change a record because a related record
is required in table `userID`.
This is strange, because I'm specifically selecting a value that's provided in the userID combo box.
Oddly, there are about 100 rows of data already in results with the same value for userID.
I thought this might be a database corruption issue, so i created a blank database and imported all the tables into it. But I still got the same error. What's going on here?
Both tables include a text field named LanID. You are using that field in this relationship, which enforces referential integrity:
The problem you're facing is due to the Lookup field properties. This is the Row Source:
SELECT [LanID].ID, [LanID].LanID FROM LanID ORDER BY [LanID];
But the value which gets stored (the Bound Column property) is the first column from that SELECT statement, which is the Long Integer [LanID].ID. So that number will not satisfy the relationship, which requires results.LanID = [LanID].LanID.
You must change the relationship or change the Lookup properties so both reference the same field value.
But if it were me, I would just eliminate the Lookup on the grounds that simple operations (such as this) become unnecessarily confusing when Lookup fields are involved. Make results.LanID a plain numeric or text field. If you want some kind of user-friendly drop-down for data entry, build a form with a combo or list box.
For additional arguments against Lookup fields, see The Evils of Lookup Fields in Tables.
If you are using a parameter query, make sure you have them in the same order as the table you are modifying and the query you have created. You might have one parameter inserting the conflicting data. Parameters are used in the order they are created...not the name of the parameter. I had the same problem and all I had to do was switch the order they were in so they matched the query. This is an old thread, so I hope this helps someone who is just now having this problem.
