I have this big query GA4 dataset and on Friday I added a new parameter.
Now, I want to query the dataset including this new param but the query is returning an error because it did not exist in the past. Is there a way to make it return an empty string or something similar if the param is not found?
Excuse my poor SQL knowledge but I am unsure of what I should be searching for online to get the correct SQL syntax. This is what I have so far:
SELECT
(PARSE_DATE('%Y%m%d', event_date)) AS eventDate,
event_name,
NULLIF(params1.value.int_value, null) AS paramName
FROM
`myDataset`,
UNNEST(event_params) AS params1
WHERE
event_name = 'eventName'
AND (params1.key = 'paramName')
LIMIT 100
paramName is the new param added on Friday. When I try to run this for yesterday it works fine but when I try to run it for the entire date range, I get This query returned no results.

Trying to automate this part of Teradata query:
c."currency" = CONCAT('FOO_', '2021') -- c."currency" = 'FOO_2021'
trying to replace the 2021 with the currently selected fiscal-year, so it is not hard-coded:
c."currency" = CONCAT('FOO_', c."fiscal-year")
c."fiscal-year" is of type VARCHAR(20).
Problem - the first query returns about 5 times more results than the second one, so I am doing something wrong, I guess. Tried with TO_CHAR(c."fiscal-year") and so on, did not succeed.
I am using Kayako Querying Language and trying to get the query to return all closed/resolved, closed/unresolved, and review tickets from a specified month. When I run the query, every ticket ever comes up, and it seems to ignore the date function I am using. What am I doing wrong?
SELECT COUNT(*) AS Total
FROM ‘Tickets'
WHERE ‘Tickets.Creation Date’ = month(June 2016) AND ‘Tickets.Status’ = ‘Closed’ OR ‘Tickets.Status’ = ‘Resolved’ OR ‘Tickets.Status’ = ‘Unresolved'
GROUP BY ‘Tickets.Status'
Thanks.
Replace the date comparison in your WHERE clause for this:
WHERE 'Tickets.Creation Date':Month = 6 and 'Tickets.Creation Date':Year = 2016
Be also careful with the quotes, you sometimes use ‘ and others '
I have the following query.
$query = $this->db->query('SELECT COUNT(*) FROM iplog.persons WHERE begin_date LIKE '2014%'');
I need to count the number of columns with a begin_date in the year 2014.
When I run this script I'm getting an error:
Parse error: syntax error, unexpected '2014' (T_LNUMBER) in C:\xampp\htdocs\iPlog2\application\controllers\stat.php on line 12
I was trying to change my CI script to
$query = $this->db->query('SELECT COUNT(*) FROM iplog.persons WHERE begin_date LIKE "2014%"');
but it caused an error.
You mean, count ROWS:
So for that, just count the number of rows you have based on a condition:
$year = '2014'
$this->db->from('iplog');
$this->db->like('begin_date', $year);
$query = $this->db->get();
$rowcount = $query->num_rows();
First, you have a simple typo regarding the use of single quotes. Your complete sql string should be double quoted so that your value-quoting can be single quoted.
Second, you are using inappropriate query logic. When you want to make a comparison on a DATE or DATETIME type column, you should NEVER be using LIKE. There are specific MYSQL functions dedicated to handling these types. In your case, you should be using YEAR() to isolate the year component of your begin_date values.
Resource: https://www.w3resource.com/mysql/date-and-time-functions/mysql-year-function.php
You could write the raw query like this: (COUNT(*) and COUNT(1) are equivalent)
$count = $this->db
->query("SELECT COUNT(1) FROM persons WHERE YEAR(begin_date) = 2014")
->row()
->COUNT;
Or if you want to employ Codeigniter methods to build the query:
$count = $this->db
->where("YEAR(begin_date) = 2014")
->count_all_results("persons");
You could return all of the values in all of the rows that qualify, but that would mean asking the database for values that you have no intention of using -- this is not best practice. I do not recommend the following:
$count = $this->db
->get_where('persons', 'YEAR(begin_date) = 2014')
->num_rows();
For this reason, you should not be generating a fully populated result set then calling num_rows() or count() when you have no intention of using the values in the result set.
Replace quotes like this :
$query = $this->db->query("SELECT COUNT(*) FROM iplog.persons WHERE begin_date LIKE '2014%'");
Double quote your entire query, then simple quote your LIKE criteria.
I am using VS2013 with SQL server 2012, VB.net. I am developing a web application.
Let me say before I ask the question that this will probably be extremely simple for this board but I have not been able to find this through googling.
I have an SQL table that holds some data, two columns (settingName (nvarchar) and settingValue (float)). I want to do the following but using LinQ.
SELECT Settingvalue
FROM Settings
WHERE settingName = 'Name1'
I have the following so far in VB.
Dim db As New GMConnectionDataContext
Dim result = From a In db.Settings
Where a.SettingName = "Name1"
Select a.SettingValue
txtEgdon.Text = result
This doesn't work as result is a double but if I add .tostring to result then the output in the text box is the full linq query not the result I am looing for.
I just need to understand this simple query so I can build on it but I just cant get it and any help offered would be great.
This is because your result is an IQueryable and not a single value(even if you expect it to be). This is also why ToString will get you the SQL that will be run against your DB.
You need to get either the First or if you are really sure this would be a single value get Single. The OrDefaults are used in the case that no value is returned so the result will be null.
A Few options:
// You expect 1 to many results and get the first
txtEgdon.Text = result.First().ToString()
// You expect 0 to many results and get the first or null in case of zero results
txtEgdon.Text = result.FirstOrDefault().ToString()
// You expect exactly 1 result and get it (you will get an exception if no results are returned)
txtEgdon.Text = result.Single().ToString()
// You expect exactly 0 or 1 results and get null or the result
txtEgdon.Text = result.SingleOrDefault().ToString()
I would prefer the FirstOrDefault()
I'm a newbie at Hibernate so excuse me if some of this is glaringly obvious but it's been a very, very long day. I am trying to create and execute a simple query in Hibernate and Toad/Oracle.
The Toad/Oracle sql reads:
select
count(*)
from
fpps_owner.fee_claim_payment_lines l,
fpps_owner.fee_claim_payments p
where
l.fee_claim_payment_id = p.fee_claim_payment_id and
p.claim_index = 87167895
The above returns 10 records, which is correct
The following Java code returns 0 records, which is NOT correct
String sLinesAvailable =
"select count(*) from " +
"fpps_owner.fee_claim_payment_lines l, fpps_owner.fee_claim_payments p " +
"where " +
"l.fee_claim_payment_id = p.fee_claim_payment_id and p.claim_index = :id";
Query qLinesAvailable = em.createNativeQuery(sLinesAvailable);
qLinesAvailable.setParameter("id", "87167895"); // fails
qLinesAvailable.setParameter("id", 87167895); // fails
List<Object> out = (List<Object>) qLinesAvailable.getResultList();
BigDecimal x = (BigDecimal) out.get(0);
Returns 0 records. Using .getSingleResult() also returns 0 records.
What am I missing here?
Any help would be GREATLY appreciated!
If you are not seeing any malformed query errors, it seems like the parameter is not binding correctly.
To debug, I'd print out that SQL statement the line after you set the parameter. This is the only way you can see the SQL after the parameter is set in order to compare it with Toad.
What does your binding file look like? Maybe you have a different name in there for the ID, so it's not able to find it based on the name. Trying binding with the parameter's order value, just as a test.
This might give some ideas: http://www.mkyong.com/hibernate/hibernate-parameter-binding-examples/
Best of luck! We've all been there :)
What happens when you try:
(Number) query.getSingleResult();
Your query isn't returning a list, but rather just a count.
Good luck.
