Description

At present, when exporting CSV data, it is simply separated by fields with specified separator, rather than strictly according to the standard CSV format.
For example, if the field contains a comma, Doris will not use the double quotation mark wrapper field when exporting, resulting in wrong columns in the final result set.

For Table(t1) data storage is ['x1,', 'x2', f2, f3].
Exporting text is x1,,x2,f2,f3. Obviously, not what we expected.

Use case

In CSV format, we could add a key-value to PROPERTIES to indicate that the exporting action will be exported by standard CSV format.

The key-value may be "csv.format.standard" = "true"

Example

SELECT * FROM tbl
INTO OUTFILE "hdfs:/path/to/result_"
FORMAT AS CSV
PROPERTIES
(
    "broker.name" = "my_broker",
    "broker.hadoop.security.authentication" = "kerberos",
    "broker.kerberos_principal" = "doris@YOUR.COM",
    "broker.kerberos_keytab" = "/home/doris/my.keytab",
    "column_separator" = ",",
    "line_delimiter" = "\n",
    "max_file_size" = "100MB",
    "csv.format.standard" = "true"
);
