Problems on creating a new dataset with Power BI's REST API

nishhtg — Thu, 10 May 2018 07:48:57 GMT

error for me , getting 202 instead of 201 for dataset creation.

this is something wrong with the conenction string for postgres.

as it very difficult to understand and findout exactly what needs to be the structure for a postgres datasource.

i have tried various patterns for the connection string with no luck.

"datasources":[
      {
         "name":"postgres",
         "connectionString":"Provider=ODBC;Data Source=postgresql://localhost/postgres?user=postgres&password=12345&ssl=prefer;Initial Catalog = postgres; Cube=Model;"
      }
   ]

"datasources":[

{

"name":"postgres",

"connectionString":"Server=localhost;Port=5432;Database=postgres;User Id=postgres;Password=root;"

}

]

}

datasources":[

{

"name":"postgres",

"connectionString":"Data Source=postgresql://localhost/Postgres?user=other&password=secret;Initial Catalog=Postgres;Cube=Model"

Data Source=jdbcostgresql://localhost/Postgres?user=fred&password=secret&ssl=true

}

]

Also, the terms CUBE and INITIAL CATALOG, PROVIDER these keys have very less info available on the net for postgres connection string. A detailed explanation for postgres connection string would be helpful here.

Check the following thread for the connection string for postgres SQL:

PostgreSQL connection through On-premise Data Gateway

Quoted:

for ODBC connection to postgres you need to get installed ODBC driver for postgres;i am using PostgresSQL Unicode(x64).

After that you have 2 options:

1) create user DSN via ODBC data source administrator (C:\Windows\System32\odbcad32.exe). In that case the connection string for ODBC data source is "dsn=dsn_name" where dsn_name represents the user dsn created via tool above

2) alternative option for connection string is: driver={PostgreSQL Unicode(x64)};server=server_name;port=5432;database=db_name

where server_name represents a server name or its IP, db_name is name of database.

For using on-premise gateway you need to use ODBC connection to postgress on power bi desktop. Then you need to configure data sources using ODBC the same way on on-premise gateway.
