Thanks very much for your invaluable contribution towards eternal learning process.
ОтветитьHello Haq,
I keep having these 2 errors while executing the .py file in VS:
1."Error Locating Server/Instance Specified [xFFFFFFFF]."
Already stackoverflowed it and changed to Automatic the SQL Browser startup mode. The Service is also running now.
2.Also there's this one: "Server is not found or not accessible. Check if instance name is correct and if SQL Server is configured to allow remote connections"
For this 2nd one I did two changes: First, I checked the name of the server with query "SELECT @@SERVERNAME;" and it checks out when I found it in Server Properties in SSMS. Your server name looks quite different from mine ( laptop name). I slightly think my issue comes from my server name somehow.
Secondly, I allowed remote connections under the menu Server Properties in SSMS. I think I'm quite close. Any suggestions?
Hope I presented the question in a neat and understandable way.
In any case, congratulations and many thanks for these series of tutorials, I'm quite close to make it!
Cheers,
NB: I've completed with same results as you the 2 previous videos on SQL Server and Postgre installation, thanks again!

ОтветитьThis is cool! But isn't this more of an Extract and Load process than Extract, Transform and Load process? Most of the time while creating the Data Marts transform scripts is a heck and long. Also in the same scenario the Load procedure is mainly for insert query of records than tables. Nevertheless good video!

HELP!!!!
1)I did the same thing and it got importeed into postgres, But i need the column data types to be in specif cformat for example Datetime, VARCHAR, DOUBLE ,INT not these text,bigint etc. Please suggest what should i do!!
2) Data is same but the data types are different, i tried changing the data type in the data frame and created custom columns with CREATE sql query but it doesnt matter as pd.to_sql always replaces that table adn creates a new one.
So what should i do?
