DESCRIPTION
@@ -10,19 +11,26 @@ DESCRIPTION
It produces a CSV (comma separated value) output for the given table. Such output is suitable for importation into databases or spreadsheets.
Used with --insert, it outputs SQL specific to backend dialect, including some constraints like NOT NULL and foreign keys.
OPTIONS
-H, --no-header Suppress header row.
-Q, --no-quote Don't wrap text-like fields (text, memo, date) in quotes. If not specified text fiels will be surrounded by " (double quote) characters.
-d, --delimiter delim Specify an alternative column delimiter. Default is , (comma).
-R, --row-delimiter delim Specify a row delimiter. Default is \\n (ASCII value 10).
-I, --insert backend INSERT statements (instead of CSV). You must specify which SQL backend dialect to use. Allowed values are: access, sybase, oracle, postgres, mysql and sqlite.
-D, --date-format fmt Set the date format (see strftime(3) for details).
-q, --quote char Use to wrap text-like fields. Default is " (double quote).
-X, --escape char Use to escape quoted characters within a field. Default is doubling.
-Q, --no-quote Don't wrap text-like fields (text, memo, date) in quotes. If not specified text fiels will be surrounded by " (double quote) characters.
-q, --quote char Use char to wrap text-like fields. Default is " (double quote).
-X, --escape char Use char to escape quoted characters within a field. Default is doubling.
-I, --backend backend INSERT statements (instead of CSV). You must specify which SQL backend dialect to use. Allowed values are: access, sybase, oracle, postgres, mysql and sqlite.
-N, --namespace prefix Prefix identifiers with prefix.
-S, --batch-size int Size of insert batches on supported platforms.
-D, --date-format fmt Set the date format (see strftime(3) for details.
-T, --datetime-format fmt Set the date/time format (see strftime(3) for details.
-0, --null char Use char to represent a NULL value.
-b, --bin strip|raw|octal|hex Binary export mode: strip binaries, export as-is, output \\ooo style octal data or output \\xx style hexadecimal data.
-B, --boolean-words Use TRUE/FALSE in Boolean fields (default is 0/1).
NOTES
Most of the formatting options actually also works with --insert.
ENVIRONMENT
MDB_JET3_CHARSET Defines the charset of the input JET3 (access 97) file. Default is CP1252. See iconv(1).
