Trying to setup a connection to a PostgresSQL server with MSSQL Polybase. Today we use Linked Server to withdraw data from the Postgresdatabases into MSSQL and it works fine. But there is some functionality with Polybase that would solve some program issus regarding joining etc, and therefore Polybase is the solution. As long it works! ;-)
But I dont get it to work. And I can't find any real help with Google.
This is the code;
> CREATE DATABASE SCOPED CREDENTIAL PG_EXAMPLE WITH IDENTITY = 'pgUSER', Secret = 'verylongpassword';
> CREATE EXTERNAL DATA SOURCE PG_EXAMPLE_DATA
>WITH ( LOCATION = 'odbc://PG_SERVERNAME:5432',
>CONNECTION_OPTIONS = 'Driver={PostgreSQL Unicode(x64)}',
>PUSHDOWN = ON,
>CREDENTIAL = PG_EXAMPLE);
Trying to create a external table:
> CREATE EXTERNAL TABLE databas(
> namn [nvarchar](255) NULL,
> datorid [nvarchar](255) NULL
> ) WITH (
> LOCATION='exampel_databas_on_PGserver',
> DATA_SOURCE=PG_EXAMPLE_DATA
> );
ERROR MESSAGE
> Msg 105082, Level 16, State 1, Line 10
> 105082;Generic ODBC error: Error while executing the query .
Can anybody spread some light here, what I'm doing wrong. Somebody perhaps tried and got it to work??
Any help and suggestion is very mutch appreciated.
Thanks!!!
Check that LOCATION is the name of the table, it may be case sensitive, and you can't specify the database neither the schema. Try connecting with the "postgres" user if you can. Also try specifying the IP instead of the hostname.
I've used the ANSI driver, try with it as well: {PostgreSQL ANSI(x64)}.
As a last resource, check the driver version, I tested with psqlodbc_12_02_0000-x64.zip.

I'm facing a problem with my PolyBase. I'm using my SQL Server to access data in MongoDB Atlas Database. However. when I try to create my external table I have the following error:
105082;Generic ODBC error: [Microsoft][MongoDBODBC] (110) Error from
MongoDB Client: No servers yet eligible for rescan (Error Code: 13053)
Additional error <2>: ErrorMsg: [Microsoft][MongoDBODBC] (110) Error
from MongoDB Client: No servers yet eligible for rescan (Error Code:
13053), SqlState: HY000, NativeError: 110 .
At the moment, my script is :
CREATE EXTERNAL DATA SOURCE mongodb_test
WITH (
LOCATION = 'mongodb://cls-data-dev-biconnector.a8m8q.mongodb.net:27015',
CONNECTION_OPTIONS = 'tls=false',
CREDENTIAL = mongodb_test
)
CREATE EXTERNAL TABLE base360 (
[_id] VARCHAR(24) NOT NULL,
[ds_Contexto] varchar(max) NULL
)
WITH (
LOCATION='[db-data].[db-mng-ins-corporate-dev]',
DATA_SOURCE= mongodb_test
);
What should I do? I didn't find a solution to solve this problem.
Can someone help me, please?
Thank you
I use DB::setDatabaseName(<database name>) to reset the databasename, then I use DB::table(<table name>)->get() to retrieve data. However laravel does not change to new database.
This is my error message:
Illuminate/Database/QueryException with message 'SQLSTATE[42P01]:
Undefined table: 7 ERROR: relation "t" does not exist LINE 1: select
* from "t" ^ (SQL: select * from "t")'
The table t is in another database. I think when I use DB::setDatabaseName(<database name>) it would work.
Thank you for your help!
I don't know your database of detail information, but this help you to check database have changed.
// current database is 'db_1'
echo DB::getDatabaseName(); // return db_1
// Set database to 'db_2'
DB::setDatabaseName('db_2');
// If success, should return 'db_2' now.
echo DB::getDatabaseName();
// Check database tables.
DB::select('show tables');
I was facing a similar issue.
But changing the database solely might not always work.
You could use config->set() like so
config()->set('database.connections.mysql', $database_name);
But in my case I had to reconnect the database to change it dynamically.
So maybe this one works for the OP.
\DB::disconnect();
config()->set('database.pgsql.database', $database_name); // psgl = Postgress
\DB::reconnect();
You'll find more info here Laravel 6 config()->get('database.connections.mysql') not matching DB:connection()
Hope it helps
I am working off of a server housing various SQL databases (accessed via Microsoft SQL Server Management Studio) and am going to use R to perform analyses and explore a specific database within the server. I have network security that permits communication between machines, drivers installed on the R server, and RODBC installed.
When I attempt to establish a Windows ODBC connection in the Control panel>Administrative>Data Sources, I can only add a data source for the entirety of the SQL server, not just for the specifc database I want to look at. I pasted the code I have been experimenting with below.
library(RODBC)
channel <- odbcConnect("Example", uid="xxx", pwd=****");
sqlTables(channel)
sqlTables(ch, tableType = "TABLE")
res <- sqlFetch(ch, "samp.le", max = 15) #not recognizing as a table
library(RODBC)
ch <- odbcDriverConnect('driver={"SQL Server"}; server=Example; database=dbasesample; uid="xxxx", pwd = "****"')
Response: Warning messages:
1: In odbcDriverConnect("driver={\"SQL Server\"}; server=sample; database=dbasesample; uid=\"xxxx", pwd = \"xxxx\"") :
[RODBC] ERROR: state IM002, code 0, message [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified
2: In odbcDriverConnect("driver={\"SQL Server\"}; server=sample; database=dbasesample; uid=\"xxxx\", pwd = \"xxxx!\"") :
ODBC connection failed
Any insight into this issue would be much appreciated.
Although while querying with the sqlQuery() function you can specify database, schema and table, e.g.
library(RODBC)
con = odbcConnect(dsn = 'local')
sample_query = sqlQuery(con,'select * from db.dbo.table')
I have not found a way to define the database from within the function parameters while using sqlFetch() or sqlSave(). An indirect way would be to define the default database in the dsn (as written in the comments). But then, you would need a different dsn for each database you would like to use.
A better solution would be to use the odbc and DBI packages instead of RODBC, and define the database in the connection statement e.g.
library(dplyr)
library(DBI)
library(odbc)
con <- dbConnect(dsn = 'local',database = 'db')
copy_to(con, rr2, temporary = F)
By the way, I found copy_to to be much faster than the equivalent sqlSave of RODBC.
How to check the defined error class of a connection (DSI) of Sybase Replication Server?
I use alter connection to change the error class associated to the DSI but I want a command that list its information in order to confirm that the error class was correctly associated.
How can I do that?
You can see it by calling rs_getconn in the RSSD database.
I don't see any rs_getconn stored proc in an RSSD database for a 15.7.1 repserver.
I do see a ral_connection_details proc which seems to do the job (example output connecting with sqsh):
> ral_connection_details "MY_ASE_SERVER", "MyDB"; -mvert
dsname: MY_ASE_SERVER
dbname: MyDB
error class: rs_sqlserver_error_class
function string class: rs_sqlserver_function_class
username: mylogin
password: NULL -- Note, the password *isn't* null, whatever
dbid: 123
Not sure where rs_getconn and ral_connection_details came from (3rd party app? custom proc? one of a slew of fly-by-night SRS management tools Sybase provided over the years?), but the simplest (and guaranteed to be in any RSSD going back eons - unless someone dropped it) is the rs_helpdb stored proc.
rs_helpdb generates a result set showing dsname, dbname, did, prs, error and function classes; for RS 15.7+ you'll also get connid (associated with multipath rep / alternate connections) and the repserver error class.
I am new to PowerBuilder.
I want to retrieve the data from MSAccess tables and update it to corresponding SQL tables. I am not able to create a permanent DSN for MSAccess because I have to select different MSAccess files with same table information. I can create a permanent DSN for SQL server.
Please help me to create DSN dynamically when selecting the MSAccess file and push all the tables data to SQL using PowerBuilder.
Also give the full PowerBuilder code to complete the problem if its possible.
In Access we strongly suggest not using DSNs at all as it is one less thing for someone to have to configure and one less thing for the users to screw up. Using DSN-Less Connections You should see if PowerBuilder has a similar option.
Create the DSN manually in the ODBC administrator
Locate the entry in the registry
Export the registry syntax into a .reg file
Read and edit the .reg file dynamically in PB
Write it back to the registry using PB's RegistrySet ( key, valuename, valuetype, value )
Once you've got your DSN set up, there are many options to push data from one database to the other.
You'll need two transaction objects in PB, each pointing to its own database. Then, you could use a Data Pipeline object to manage the actual data transfer.
You want to do the DSNLess connection referenced by Tony. I show an example of doing it at PBDJ and have a code sample over at Sybase's CodeXchange.
I am using this code, try it!
