Is there a way (setting or shortcut) for displaying the total row count of a query that outputs more than 500 rows - that is, without modifying the "Result set page size" value in preferences? I'm looking essentially for the output of select count(*) from (<query>) t in addition to the displayed rows.
Click on page-size of the result-set
You can change it in settings:
File --> settings
Then in Database --> Data Views --> Uncheck Limit page size to 500
Alternative to accepted answer (clicking to page-size), click the Last Page icon and it shows the count of items
Answering my own question and not accepting it because I'm hoping there's a better way, but you can create a live template:
SELECT count(*) FROM ($SELECTION$) tablenameyoullneveruse
Select your query, then use Surround with Live Template...
Still hoping for a simultaneous solution (not have to build 2nd query).

I am wondering if there is a way to limit the number of rows generated from grafana templating.
I can have a drop down variable "$x"on my grafana page and I can select the row editor and say repeat row for every value under $x.
Based on different criteria, I can have x anywhere between 1 and like 160 rows. I need to only be looking at about 10 at a time. I am wondering if I can control the number of rows shown/change the rows shown somewhere in grafana.
I can manually select items from the $x drop down to show only a few items of course, but its a matter of selecting only say.. 10 items right when the page loads.
Please let me know if I am not describing the problem correctly or if I need to clarify more.
Thanks,
Karan
As far as I know there is no direct option for this but there are some ways you may be able to achieve what you want.
You could select your ~10 default entries and then save the dashboard this will save the selected ones in the dashboards JSON. (or modify the JSON of the dashboard directly)
You could use the regex field in the template settings to filter some of your values and split them in groups this way. (one variable per regex group)
You could change your data in elasticsearch in order to use multiple fields where you can split on.
see PR #5616 as #Daniel Lee mentioned
In general I think you get a faster response to this in grafana directly at github.
I'm testing Kibana 4 for a project.
I have created an index from my database table which is composed by 3 fields:
Date
User
Action
I would like to display my index as a simple table (3 column, N rows) in my dashboard.
I tried to use "Data table" visualization but I can't find a way to display my results without any Metrics (Count, Sum etc...)
Maybe is pretty simple and I missed something... is there a way to do this?

On the Discover tab, create a view that has just the fields you want and then save that as a search.
On the Dashboard tab, click on Edit then hit the + Create new button to add a widget, but if you look at the top, there's a Searches tab. Select that and add your saved search in.

I was a bit confused when I read #Alcanzar's answer so I am sharing a little more noob-friendly step-by-step how-to here :
STEP 1 : Create the Index Pattern
STEP 2 : Go to the Dashboard view, and create a view on your index
Select each column you want to include/add in your view by clicking "add" on it (The confusing part is that until you do that, you will have a "scrambled" view listing everything in a jumbled way.)
STEP 3 : Go to the Dashboard view, and create a view on your index
The trick is to select the specific columns you want to include... and voila !
Don't forget to save your view, this will help a lot in the process.
In Kibana 7.5.0 you can do it as follows:
Go to Discover section
Select fields you are interested in
Click on Save to save your discover search so you can use it in visualizations and dashboards
Click on Dashboard and create a new dashboard
Click on Add and select the panel
There is no step 6
The accepted solution has its pros (if, for simplicity, you see your index as a table, this is the only way to deal with rows naturally) but also cons (it allows the user to see too much information, by expanding the records that appear in the table; users cannot get an export of the values).
So if you plan to build tables to use in reports seen by users which should not see everthing and may want to get exports of the data, I recommend a different (hacky) approach using Table visualizations:
Say you have three columns A, B and C:
If there are no duplicates considering the combined values of A and B, you can use these two vales as aggregation fields, and then set a Max or Top hit Metric for C.
If even A, B and C have duplicates, then you can use the three of them as aggregation fields and add a Metric count, that will give you the number of repeated rows. This solution makes somehow sense, because instead of repeating the same row 'n' times you just tells you should have repeated 'n' times that row.
If A and B have duplicates but A, B and C are unique, then there is, afaik, no elegant solution. You have to use the three of them as aggregation fields, but then you would have a dummy metric at the end (e.g. count, always equal to 1).
Why? why do we have to go through all of this? that is another question...

I am using Oracle 11g with Toad 12.5.1.1 and the output grid only shows me 500 rows at a time.
Is there a way to make toad display all the results at a time or is there a way to find the number of rows returned even though the grid only shows 500 records ?
Well, that is considered a feature.
If you enter the grid and hit Ctrl+End it will fetch all rows for you.
If that's what you want to do, you need to set the OCI Array Buffer Size not the Limit Grid Fecth.
See here for more details:
http://www.toadworld.com/products/toad-for-oracle/f/10/t/8909.aspx
Right click on the grid and use the option "Record count...". It will display on a floating windows the total record count.
Other option is to encapsulate your query in a SELECT count(*) FROM (your query).
I am working on jqGrid.I had a problem in the navigator rowList.
my data to this field is like this rowList:['25','50','75','-1'].
I am using -1 to display all the records.In the row list,i wish to use "All" instead of "-1" to display all the records is their any possibility to do this.
Thanks in advance.

There are no All value as rowNum and in the rowList array. You should also not use -1 (see documentation about rowNum for example) or other negative values. The value -1 was allowed in some cases in the old releases of jqGrid, but it is no more supported in last releases. The value like 1000, 10000 are good enough depend on your requirements.
Having some realistic restrictions in the number of displayed rows is a good idea independent on the jqGrid support. No real user are able to examine 1000 rows of information without data paging, filtering (searching) or at least scrolling of the data in the web browser. So the displaying of about 50 or 100 row as maximum is what I would recommend you. Look at another old answer for more details and see included examples.
