Title: TPS Table with 357,899 records - times out
Post by: rupertvz on April 07, 2019, 10:58:21 PM

Hi Guys,

I have a TPS table with 357,899 records which I am trying to link / view in a NWB.
I have a simple filter to display some of the records.

I am getting:

This page isn?t working - didn?t send any data.
ERR_EMPTY_RESPONSE

With less records the table contents display correctly.

Am I perhaps doing something wrong?  Or is this amount of records too many for a TPS table to display?

When I remove the NWB filter, the NWB loads fine (showing all records)

When I replace the NWB filter, the more records matches the filter, the quicker the browse loads
With little or no records matching the filter, the browser times out.

Hallo!

Can you post the filter?
Where you put filter code? in template or embed code?

Thank you Robert,

The filter works fine with less records
The problem seems related to the large data set.


I tried two different options in the template;

Option 1:
Kindly see screenshot attached, my filter value "Pfe" is stored in LOC:Pfe

Option 2:
'C007:Pfe = <39>'&p_Web.GetSessionValue('GLW:Pfe')&'<39>'

  * Where GLW:Pfe is my "Pfe" session value

I do not use filter in template (very rare)
Try to use in embed code: Before Browse Loop > Set Filter

loc:FilterWas = UPPER(C007:Pfe)&' = <39>'&UPPER(p_web.GSV('GLW:Pfe'))&'<39>'
ThisView{prop:Filter} = loc:FilterWas

Check and see id you see any difference.
I have TPS with more then 800.000 records and show just fine.

Hi Rupert,

a) Do you have a KEY on the C007:PFE field ?
b) Is the key set as Case Sensitive?
c) Is the field a string or a long?

cheers
Bruce

Hi Bruce,

a) Do you have a KEY on the C007:PFE field ?
I have a single key, with only one component on C007:Pfe (Not unique)
I also have other keys with C007:Pfe as a component

b) Is the key set as Case Sensitive?
No, this key is not case sensitive

c) Is the field a string or a long?
String(10)

Hi Rupert,

The key exists, but is case insensitive. So the filter must be case insensitive as well. ie not

'C007:Pfe = <39>'&p_Web.GetSessionValue('GLW:Pfe')&'<39>'

but more like

'UPPER(C007:Pfe) = <39>' & UPPER(p_Web.GetSessionValue('GLW:Pfe')) & '<39>'

Cheers
Bruce
