问题 I'm getting following error while loading my odoo 12 server on windows 7 You don't have the permission to access the requested resource. It is either read-protected or not readable by the server.

问题 So I installed postgreSQL version 9.2.4 using the default installer settings on Windows 7 64 bit. Then I launched the SQL Shell(psql) command line tool and enter all the defaults plus the password I used during the install. It logs in. The problem is that a database cannot be created, or so it appears. I typed in creatdb mydb also tried CREATE DATABASE mydb I assume something happens, but when I type \list I just see the default installed databases. Am I missing something here? Coming from

问题 I was reading this link: Does PostgreSQL support "accent insensitive" collations? about how to use accent insensitive queries. and this link PostgreSQL: How to make "case-insensitive" query about using case insensitive queries. Tested a query in pgAdmin: SELECT * FROM Customers WHERE unaccent(Customers.customername) ILIKE unaccent('abc%') and it works fine. It gives me the expected results. However, my front end is in MS Access 2016, is there a way to send this query to Postgres from within

问题 My Flask app(postgresql db) is working fine in local.

问题 I have to write a query to update a record if it exists else insert it. I am doing this update/insert into a postgres DB. I have looked into the upsert examples and most of them use maximum of two fields to update. However, I want to update multiple columns. Example: query="""INSERT INTO table (col1,col2,col3,col4,col5,col6,col7,col8,col9,..col20) VALUES(%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s,%s) ON CONFLICT(col2) DO UPDATE SET (col1,col2,col3,col4,col5,col6,col7,col8,col9,.

问题 I have an existing postgres database with the database "testdb" and the database schema testdbschema".

Everything is working well, except the configuration of the database schema. Here is my web

问题 With pgsql function SelRec(integer) as defined below: -- select record CREATE OR REPLACE FUNCTION SelRec(_sno integer) RETURNS SETOF app_for_leave AS $BODY$ BEGIN RETURN QUERY SELECT * FROM "app_for_leave" WHERE "sno"=_sno; END $BODY$ LANGUAGE 'plpgsql' VOLATILE; I tried to call this function inside my python code, and expected the returned result as query object which furthermore I could get an individual value inside the query object. import psycopg2 connection_string = 'postgresql:/

问题 I have two polygon layers. I want to run st_intersection on them, to give the result of the areas where they overlap as a new layer. The new layer should contain the attributes from both input layers. I found this image which seems to illustrate my desired end results. My two input layers are both polygons: SELECT st_geometrytype(geom), COUNT(*) FROM a GROUP BY st_geometrytype(geom) -- Result is 1368 st_polygons SELECT st_geometrytype(geom), COUNT(*) FROM b GROUP BY st_geometrytype(geom) --

问题 I'm terribly sorry if I can't start another post which is connected to my previous one but my question is somewhat different. I noticed that I really can save new data in my database as long as I never added data to the database by using the line spring.datasource.initialization-mode=always in my application.properties and made a data.sql file with a few insert statements.
