I've developed a huge table in excel and now facing problem in transferring it into the postgresql database. I've downloaded the odbc software and I'm able to open table created in postgresql with excel. However, I'm not able to do it in a reverse manner which is creating a table in excel and open it in the postgresql. So I would like to know it is can be done in this way or is there any alternative ways that can create a large table with pgAdmin III cause inserting the data raw by raw is quite tedious. Thanks in advance for all the helps! The typical answer is this: • In Excel, File/Save As, select CSV, save your current sheet. • transfer to a holding directory on the Pg server the postgres user can access • in PostgreSQL: COPY mytable FROM '/path/to/csv/file' WITH CSV HEADER; -- must be superuser But there are other ways to do this too.

PostgreSQL is an amazingly programmable database. These include: • Write a module in pl/javaU, pl/perlU, or other untrusted language to access file, parse it, and manage the structure. Caballeros Del Zodiaco Descargar Capitulos Rar on this page.

• Use CSV and the fdw_file to access it as a pseudo-table • Use DBILink and DBD::Excel • Write your own foreign data wrapper for reading Excel files. The possibilities are literally endless.

For python you could use openpyxl for all 2010 and newer file formats (xlsx). Al Sweigart has a full tutorial from automate the boring parts on its very indepth and the whole book and accompanying Udemy course are great resources. From his example >>>import openpyxl >>>wb = openpyxl.load_workbook('example.xlsx') >>>wb.get_sheet_names() ['Sheet1', 'Sheet2', 'Sheet3'] >>>sheet = wb.get_sheet_by_name('Sheet3') >>>sheet Understandably once you have this access you can now use to parse the data to postgres as you normally would do. This is a link to a list of python resources at also provides a large array of features for using python in place of vba in excel. A method that I use is to load the table into as a data.frame, then use dbWriteTable to push it to PostgreSQL. These two steps are shown below. Load Excel data into R R's data.frame objects are database-like, where named columns have explicit types, such as text or numbers.

There are several ways to get a spreadsheet into R, such as. However, a really simple method is to select the range of the Excel table (including the header), copy it (i.e. CTRL+ C), then in R use this command to get it from the clipboard: d. As explained here With ogr_fdw module, its possible to open the excel sheet as foreign table in pgsql and query it directly like any other regular tables in pgsql. This is useful for reading data from the same regularly updated table To do this, the table header in your spreadsheet must be clean, the current ogr_fdw driver can't deal with wide-width character or new lines etc. With these characters, you will probably not be able to reference the column in pgsql due to encoding issue.

(Major reason I can't use this wonderful extension.) The ogr_fdw pre-build binaries for windows are located here change the version number in link to download corresponding builds. Extract the file to pgsql folder to overwrite the same name sub-folders. Restart pgsql. Before the test drive, the module needs to be installed by executing: CREATE EXTENSION ogr_fdw; Usage in brief: • use ogr_fdw_info.exe to prob the excel file for sheet name list ogr_fdw_info -s 'C:/excel.xlsx' • use 'ogr_fdw_info.exe -l' to prob a individual sheet and generate a table definition code. Ogr_fdw_info -s 'C:/excel.xlsx' -l 'sheetname' Execute the generated definition code in pgsql, a foreign table is created and mapped to your excel file.

It can be queried like regular tables. This is especially useful, if you have many small files with the same table structure. Just change the path and name in definition, and update the definition will be enough.

This plugin supports both XLSX and XLS file. According to the document it also possible to write data back into the spreadsheet file, but all the fancy formatting in your excel will be lost, the file is recreated on write. If the excel file is huge.

This will not work. Which is another reason I didn't use this extension.

It load data in one time. But this extension also support ODBC interface, it should be possible to use windows' ODBC excel file driver to create a ODBC source for the excel file and use ogr_fdw or any other pgsql's ODBC foreign data wrapper to query this intermediate ODBC source. This should be fairly stable. The downside is that you can't change file location or name easily within pgsql like in the previous approach.
