insert-update

问题 So from time to time I get new exports of a cities database of POIs and info about them and I want to have all that data in my MongoDB with a Loopback-API on it. Therefore I reduce the data to my desired structure and try to import it. For the first time I receive such an export, I can simply insert the data with insertMany(). When I get a new export, it means that it includes updated POIs which I actually want my existing POIs to be replaced with that new data. So I thought I'd use

问题 I need to create a trigger that fills in a project name for table based off the filename. Currently, I am able to fill in the first project name on import based off the first hostname.

问题 I'm running the following code to update the database according to the data I read from CSV file. I've tried to debug, and check the console and it's running through the whole 800 records. I don't get any error, but only the first record is inserted. If I'm using persist instead of merge, I got "Cannot persist detached object" error. for (String[] data : dataList) { log.debug("Reading data no " + (i++)); EntityManager em = PersistenceUtil.getAgisDbEntityManager(); EntityTransaction tr = em

问题 In postgresql 9.5 how can the INSERT ... ON CONFLICT (id) DO UPDATE... syntax be used with a sequence ID? In a table tbltest that has the following columns: tbltest_ID tbltest_Name tbltest_Description Where tbltest_ID has a sequence in the db that does auto increment. The following works fine for updates, eg; updating the record with an ID of 4: INSERT INTO tbltest ( tbltest_ID, tbltest_Name, tbltest_Description) VALUES (4, 'test name','test description') ON CONFLICT (tbltest_ID) DO UPDATE

问题 I created a table to hold counts of work orders by asset tag. I have 2 fields, asset_tag (which is unique) and the wo_count. I am trying to write a query that will insert/update the counts in the table. Through research on ON DUPLICATE KEY UPDATE , I have come up with this, but am getting unknown column errors. INSERT INTO mod_workorder_counts (asset_tag, wo_count) (SELECT t.asset_tag, count(*) AS cnt FROM mod_workorder_data t WHERE t.asset_tag IS NOT NULL GROUP BY t.asset_tag) ON DUPLICATE

问题 I am the application administrator for a ticketing system at my organization. We're adding a new client, and need to import their customer records into our system. However, we have been denied access to simply grab these records from a direct database connection. We are limited to entering their ticketing system, and running an export of the existing records to a CSV file.
