Double-Quotations Supported When Importing and Exporting CSVs

When importing and exporting CSVs, SQream now supports using quotation characters other than double quotation marks (").

For more information, see the following:

Note the following:

  • Leaving <x> unspecified uses the default value of standard double quotations .

  • The quotation character must be a single, 1-byte printable ASCII character. The same octal syntax of the copy command can be used.

  • The quote character cannot be contained in the field delimiter, record delimiter, or null marker.

  • Double-quotations can be customized when the csv_fdw value is used with the COPY FROM and CREATE FOREIGN TABLE statements.

  • The default escape character always matches the quote character, and can be overridden by using the ESCAPE = {'\\' | E'\XXX') syntax as shown in the following examples:

    copy t from wrapper csv_fdw options (location = '/tmp/file.csv', escape='\\');
    
    copy t from wrapper csv_fdw options (location = '/tmp/file.csv', escape=E'\017');
    
    copy t to wrapper csv_fdw options (location = '/tmp/file.csv', escape='\\');
    

For more information, see the following statements:

  • COPY FROM - Loading data from files on the filesystem and importing it into SQream tables.

  • CREATE FOREIGN TABLE - Creating a new foreign table in an existing database.
