Hi all,

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 : SELECT * FROM ( SELECT
"dim_kliniek"."kli_kliniek_code",
"dim_dbc_diagnose"."dia_dbc_diagnose_code",
"dim_dbc_diagnose"."dia_dbc_specialisme_code"
FROM "dwh"."dim_kliniek"
INNER JOIN "dwh"."fct_subtraject"
ON (
"dim_kliniek"."kli_id" = "fct_subtraject"."kli_id"
)
INNER JOIN "dwh"."dim_dbc_diagnose"
ON (
"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 : SELECT c.oid, a.attnum, a.attname, c.relname, n.nspname, a.attnotnull OR (t.typtype = 'd' AND t.typnotnull), pg_catalog.pg_get_expr(d.adbin, d.adrelid) LIKE '%nextval(%' FROM pg_catalog.pg_class c JOIN pg_catalog.pg_namespace n ON (c.relnamespace = n.oid) JOIN pg_catalog.pg_attribute a ON (c.oid = a.attrelid) JOIN pg_catalog.pg_type t ON (a.atttypid = t.oid) LEFT JOIN pg_catalog.pg_attrdef d ON (d.adrelid = a.attrelid AND d.adnum = a.attnum) JOIN (SELECT 24121 AS oid , 4 AS attnum UNION ALL SELECT 24055, 4 UNION ALL SELECT 24055, 3) vals ON (c.oid = vals.oid AND a.attnum = vals.attnum)[/code]

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?


Thanks,
