PostgreSQL data source – Freehand SQL query view error
1 December, 2015
I've succesfully succesfully set up a data source (PostgreSQL 9.4.5 on CentOS 7) for our Yellowfin 7 install (Windows 2012R2). When I try to create a view in the drag 'n drop editor, everything works. But, when I use the freehand SQL editor to create a view, which is what we intend to use, I get the following error:
[code]SQL statement is invalid.
The error message returned from the database was:
Cannot change transaction read-only property in the middle of a transaction.[/code]
This happens even when I copy the code generated by the drag 'n drop editor. This particular code runs fine in a separate SQL-client, so I guess both code and privileges are OK.
When I examine the PostgreSQL logs on the data source, I saw that Yellowfin generates some additional statements besides the query:
[code]< 2015-12-01 11:22:04.917 CET >LOG: execute
INNER JOIN "dwh"."fct_subtraject"
"dim_kliniek"."kli_id" = "fct_subtraject"."kli_id"
INNER JOIN "dwh"."dim_dbc_diagnose"
"fct_subtraject"."dia_id" = "dim_dbc_diagnose"."dia_id"
OFFSET 100 LIMIT 10 ) AS T WHERE 1 = 0
< 2015-12-01 11:22:04.918 CET >LOG: execute
Again, both queries from the log run fine in a SQL-client using the same credentials. I have a feeling I'm missing something obvious here; anybody has some pointers?
I just wanted to let you know that we are troubleshooting this task via the case you opened through our CRM.
I will be reaching out to you via email rather than the forum. Please let us know if you have any questions!
