As I mentioned earlier, if you attempt to show tens of thousands of rows of data on a read-only grid, the form will barely load, and even if it did, the user experience would be miserable. The MOST i'd ever consider all at once is maybe a hundred, and that's only if it's critically required (and on the simple side).

Why can't you just use paging?

The best way is to use record for sure.

But I guess you could do this with queries and a read only grid field with custom pagination.

You will need a query to fetch the total count, and with another query and custom pagination buttons, you could load the next/previous batch of data that you want to present in the grid at that time. So you won't query the entire table but only the particular batch of data.

I don't recommend this way as it requires a lot of effort to implement it and its tricky as the CDT should be mapped to a table with auto increament ID values enabled so you could count what the startIndex of the pagination will be each time. If the table changes drastically (i.g a view), then its an issue.

Thanks Mike Schmitt ,

but how then we achieve this is there any another way?

I'm not sure how this is relevant - totalCount is returned even when you take a very small slice of the data in your query, as long as you set the "fetchTotalCount" parameter to TRUE.

It'll time out if the query is not performant (i.e. slow views, etc). But the Memory Circuit Breaker is separate from this and will prevent a data set over a certain size from being returned.

Mike Schmitt , won't the query timeout when its trying to return large data?

RE: need help with fetching the data using the entity

Mike Schmitt — Thu, 08 May 2025 12:05:19 GMT

The simple answer is: a!queryEntity() has a BUILT-IN SIZE LIMIT (i.e. total amount of data returned, unrelated to the overall number of rows).

And also: even if you COULD successfully query 21,568 rows of data successfully into a local variable, if you tried to display that all at once in a read-only grid, the form would either refuse to load or be MISERABLY slow. And if you're planning to page it anyway, then you should be paging it at query time, not after.

if i give the column selection at that time count is changing,
a!queryEntity(
entity: cons!Ltable,
query: a!query(
pagingInfo: a!defaultValue(
value: ri!pagingInfo,
default: a!pagingInfo(
startIndex: 1,
batchSize: 10
)
)
),
fetchTotalCount: true
)

Can you attach code screenshot as well?
Also seems the count has increased by a 1000 now. Was any change done to the table or query?

Can you attach a screenshot of the code and the output?

RE: need help with fetching the data using the entity

Ram Ganesh — Thu, 08 May 2025 09:45:48 GMT

yes, i can able too see.

RE: need help with fetching the data using the entity

sarathkumar13 — Thu, 08 May 2025 09:44:27 GMT

In database, you are able to see 26191 rows??

RE: need help with fetching the data using the entity

Ram Ganesh — Thu, 08 May 2025 09:36:13 GMT

in QUERYENTITY IF I USE TOTALFETCHCOUNT:TRUE i can see only 21568 only.

RE: need help with fetching the data using the entity

sarathkumar13 — Thu, 08 May 2025 09:22:10 GMT

What do you mean by you can fetch only 21568 rows?
Where did you find this count?

RE: need help with fetching the data using the entity

Ram Ganesh — Thu, 08 May 2025 09:13:26 GMT

To display the data in Read-only grid also need TotalCount,

Total count is 26191,

Does the first table have duplicate rows?

RE: need help with fetching the data using the entity

Harsha Sharma — Thu, 08 May 2025 08:32:59 GMT

why do you need all these rows at once?

what does the total count come up in 1st query?

If you get data in batches are you able to get the last rows which are missing?
