I want to use a table in penthaoo spoon. The table exists, I double-checked it. My connection to database configuration uses dynamics variables, so it shows an error when configuring table exists step. You can see the error below:

I am working in QGIS through the DB Manager by running some spatial queries. After I create new tables with the queries I need to export the tables as new geopackages.
I've tried using the Export to Vector file inside the DB Manager but I get the following error message:
Error 2 Creation of data source failed (OGR error:
sqlite3_open(/Users/xxx/Documents/xxx/xxx/xxx/xxxx/xx/new_geopackage_layer.gpkg)failed:
unable to open database file)
I've read a couple of posts and they said I needed to create an empty geopackage first and then export the table and save it inside the geopackage but that did not work either. When I try to save inside an existing geopackage
I get an error saying:
"geopackage.gpkg already exists. Do you want to replace it? A file or
folder with the same name already exists in the folder xxx Replacing
it will overwrite its current contents."
If I choose to overwrite then I get a second error message saying:
" Error 1 Unable to create the datasource.
/Users/xxx/Documents/xxx/xxx/xxx/xxx/xxxx/new_geopackage.gpkg exists
and overwrite flag is false."
All I want is to be able to run spatial queries inside QGIS and be able to export the tables created with the queries as geopackages.
It seems that as of now I won't be able to do this from inside QGIS but instead will need to use ogr2ogr command to export to any file type.
Any help would be really appreciated.
Thank you
I tried to build an Offer-Ready Docker container on Azure Cloud. Although I created a new (blank) table in PostgreSQL, I got this strange error message.
javax.servlet.ServletException: org.eclipse.jetty.servlet.ServletHolder$1: org.flywaydb.core.api.FlywayException: Found non-empty schema(s) "public" without schema history table! Use baseline() or set baselineOnMigrate to true to initialize the schema history table.
I double-checked the database, there is no table in schema "public". I didn't have that problem on AWS. Has anybody an idea what is different on Azure?
I had the same experience once.
The PostgreSQL database on Azure seemed empty (\dt returned no results),
But Flyway claimed the database was not empty (and therefore would not apply the migration scripts, for fear of interfering with whatever was already there).
Here is what I did was:
Create a new schema within the database e.g. myschema
Delete the default schema called public
Add the parameter currentSchema=myschema to the JDBC URL
And then it worked. I never got to find out what the root cause of this problem was.
EDIT: This link might provide more information on what objects are in the "public" schema by default on Azure PostgreSQL: https://community.atlassian.com/t5/Jira-questions/Re-quot-database-that-is-not-empty-quot-when-trying-to-use-azure/qaq-p/1308795/comment-id/410329#M410329
I'm new to postgres so this problem is probably a relatively easy one for someone else. However, I have spent many frustrating hours trying to figure out the solution. I have an Access Database of metadata that must be kept updated for sending records to other groups. I also have a database using PostgreSQL and PGAdmin which also has these same metadata tables. Currently these tables in the Postgres database get updated manually by exporting the Access tables as excel files, and then importing them into the SQL tables. It's not the most efficient process and could lead to errors in the SQL database if someone forgets to check before running any queries that they are using the most recent data from Access. So I would like to integrate some of the tables from my Access database with my Postgres database.
Originally I tried just installing drivers to export the Access tables directly to Postgres which worked, but not in the way that I wanted since it just brings in a table which I would still need to manually update. From my understanding, I can create a server connection in postgres to access and that would then bring in updated data using a foreign data wrapper.
I tried to use ogr_fdw.
CREATE EXTENSION ogr_fdw;
When I try:
CREATE SERVER metadata
FOREIGN DATA WRAPPER ogr_fdw
OPTIONS (
datasource 'H:\Databases\20170712.accdb',
format 'ODBC' );
I receive: ERROR: unable to connect to data source "H:\Databases\20170712.accdb"
SQL state: HV00D
When I try:
CREATE SERVER metadata
FOREIGN DATA WRAPPER ogr_fdw
OPTIONS (
datasource 'H:\Databases\20170712.accdb',
format 'ACCDB' );
I receive: ERROR: unable to find format "ADDCB"
HINT: See the formats list at http://www.gdal.org/ogr_formats.html.
I also tried MDB and received the same error. However, MDB is the code name given by the website but it says that it needs JDK/JRE to compile and I'm not really sure if that's another type of driver that I would need or what it is.
When I try:
CREATE SERVER metadata
FOREIGN DATA WRAPPER ogr_fdw
OPTIONS (
datasource 'H:\Databases\20170712.mdb',
format 'ODBC' );
I receive: ERROR: unable to connect to data source "H:\Databases\20170712.mdb"
SQL state: HV00D
Hint: Unable to initialize ODBC connection to DSN for DRIVER=Microsoft Access Driver (*.mdb);DBQ=H:\Databases\20170712.mdb,
[Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
However I thought after looking at the github help page for ogr_fdw didn't need ODBC and special drivers https://github.com/pramsey/pgsql-ogr-fdw/blob/master/FAQ.md.
A lot of this is probably due to my limited knowledge of the terminology when I'm reading through a lot of this stuff. Also my Access database is an .accdb file but since that wasn't working I tried around with mdb and ODBC as the "format" too. If anyone has any suggestions I would greatly appreciate it.
Thanks!
I'm trying to setup a simple replication from MySQL to Postgres. Identical schemas. After following the steps in the Demo Tutorial with a slight change (using MySQL and Postgres drivers) I am still unable to get the replication working.
A few changes were needed based on complaints after running bin/sym
SET GLOBAL show_compatibility_56 = ON needed to be set in the MySQL DB
For Postgres I needed to use protocolVersion=3 instead of 2 which was set in the example.
The weird thing is that SymmetricDS is able to create the sym_* tables, but complains about not being able to read them. I have verified that the tables do not exist before bin/sym is run, but do exist after. Here is an excerpt from the log
// Successful creation of table
[store-001] - PostgreSqlSymmetricDialect - DDL applied: CREATE TABLE "sym_notification"(
"notification_id" VARCHAR(128) NOT NULL,
...
PRIMARY KEY ("notification_id")
)
...
// Unable to read from created table
[store-001] - PostgreSqlDdlReader - Failed to read table: sym_notification
[store-001] - PostgreSqlDdlReader - Failed to read table: sym_notification
[store-001] - AbstractDatabaseWriter - Did not find the sym_notification table in the target database
[store-001] - PostgreSqlDdlReader - Failed to read table: sym_monitor
[store-001] - PostgreSqlDdlReader - Failed to read table: sym_monitor
[store-001] - AbstractDatabaseWriter - Did not find the sym_monitor table in the target database
The same error apply for all the sym_* tables.
The databases are running in Docker, but since SymmetricDS is not complaining about being unable to connect, and is able to create the tables, I assume it is not related to Docker.
The database in the Postgres DB is created by the same user as specified in engines/store-001.properties. Could this still have something to do with roles and access privileges?
If you upgrade to the latest JDBC driver from Postgres it will work.
Replace the existing Postgres driver from the lib directory from the latest from here: https://jdbc.postgresql.org/download.html
Try to connect to the postgres database with the same username/password used by symmetric-ds from some DB navigator, for example Jetbrain's Datagrip and then try inserting, updating, selecting something from sym_* tables. Assign access rights to the user if necessary.
When using Postgres 9.6.1 (current latest release) the following error is logged on the server when running bin/sym
ERROR: column am.amcanorder does not exist at character 427
The problem was resolved by using Postgres 9.5.5 instead thanks to Nick Barnes pointing this out in a comment.
I am trying to setup a CDC in Talend on an Oracle database. I am following the steps as listed here: https://www.talendforge.org/tutorials/tutorial.php?language=english&idTuto=42
However, when i try to establish the CDC in the main DB conneciton, i get a message saying "Database information must be filled to use the cdc!" and the Create Subscriber button is disabled.
What could I be doing differently? I have created two connections pointing to the same database, and have also retrieved the table schema in my main connection.
