In this post, I am sharing a demonstration on how to export or import CSV data using the PostgreSQL COPY command. The CSV files are most famous for the necessary data migration activities. Database developer does not need to write or create any particular database link between two servers. Connect Sqlstate Im004 Microsoft.

They can easily import data in CSV and export that CSV into another server and also CSV file does not have any data length limitation like any other XLS file. User can store millions of records into CSV file. This technique is preferred only for temporary purposes, and if it continues the process, the user has to write some automated process like database server replication. PostgreSQL provides the COPY command to import or export CSV data into the PostgreSQL table.

Let me demonstrate this: First, I create one table and import data from CSV file. I have already created a CSV file with sample data. Make sure that, your table column and CSV column would be same. You can create this CSV file using a comma delimited save as option of Microsoft excel.
