Hi Team,
Thanks a lot all of you, for providing support peoples like me.
Could you please provide a suggestion on COPY command.
Environment:
DB Version:9.5.15
postgis:
Table contain GIS data.
I have a table with GIS data, its around 300MB and 2Lacks+ records. I
want to export all the records to the CSV file. I can able to export the
table data into a CSV file, but the exported CSV file size around 162MB.
While I am trying to opening the excel it is taking a long time and also
while applying vlookup excel is getting hang.
I am using below command :
\copy cities TO '/var/lib/pgsql/cities.csv' (DELIMITER ',', FORMAT
'csv', HEADER)
I am trying to achieve the following :
1. The exported CSV file should have within 10MB.
You can select less then the entire table with a query:
https://www.postgresql.org/docs/9.5/sql-copy.html
query
A SELECT or VALUES command whose results are to be copied. Note
that parentheses are required around the query.
2. The excel file should open quickly and able to perform vlookups
without any problems(like hang).
That is something you will need to take up with MS.
Could you please provide suggestions on below queries:
1. what I am trying to achieve, is the right assumption?.
2. Can we use this command to use for the above use case?.
3. Is there any tool/extension available for the above use case.?
The MS Office data tools for pulling directly from database into
spreadsheet via ODBC.
Do you use a programming language?
If so use its libraries to pull data out and into CSV or directly into a
spreadsheet.
Your inputs are highly appreciated.
Regards,
Postgadm.
