Paging grid row limitation

RE: Paging grid row limitation

This is a known issue when querying from a View where the View's CDT is configured with a Primary Key column that is not actually unique within the View's data set. In other words, if whatever column you've defined as "primary" in the CDT has duplicates in different rows of the view table, only the unique instances will be counted when returning the paged TotalCount. I don't consider this an error within Appian but rather an error in implementation. The solution to this is to configure your View such that it has at least one column that will always be unique, and configure the CDT for the view to use this column as the Primary Key.

Can you check to see if your primary key is unique? Appian should always return the correct number of rows if you use -1 as batch size, but it relies on a count of the IDs for all other batch sizes, so it can return incorrect numbers if the primary key isn't unique.

Even if you don't have a unique field, you may need to create a view that uses a row count field or something to make sure your total counts are correct.

Hi,

Can you try this way,

create a separate query rule and placed here..In that query rule placed startindex:1 and batcsize:-1 but in this rule used (1,25)

load(

local!pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: 25,
sort: a!sortInfo(
field: "A",
ascending: false()
),

with(
local!datasubset:todatasubset( rule!queryrule,local!paginginfo),

a!gridField(
label: "Sample Report",
totalCount: local!datasubset.totalCount,
columns: {
a!gridTextColumn(
label: "A",
field: "A",
data: tointeger(
index(
local!datasubset.data,
"A",
null
)
)

value:local!pagingInfo.

saveInto:local!paginfinfo

.
)

Yes I checked in database it has 3000+ records.

The following is the code snippet:

load(

local!pagingInfo: a!pagingInfo(
startIndex: 1,
batchSize: 25,
sort: a!sortInfo(
field: "A",
ascending: false()
),

with(
local!datasubset: a!queryEntity(
entity: cons!TEST_DS,
query: a!query(
logicalExpression: a!queryLogicalExpression(
operator: "AND",
filters: {
a!queryFilter(
field: "A",
operator: "not null"
),
a!queryFilter(
field: "B",
operator: "not in",
value: {
"Closed",
"Complete",

}
)
}
),
pagingInfo: local!pagingInfo
)
),

a!gridField(
label: "Sample Report",
totalCount: local!datasubset.totalCount,
columns: {
a!gridTextColumn(
label: "A",
field: "A",
data: tointeger(
index(
local!datasubset.data,
"A",
null
)
)

.
)

When i pass -1 as batch size, all the 3000+ records are seen in the report but with any other batch size I can see only 1,175 records

Hi,

can you please check your database, it contains 3000+ records?

if it is yes, it should be displayed

Can you share your code snippet if possible will find out the problem.
