`Import/Export Data Dialog`:index:
**********************************
Use the *Import/Export data* dialog to copy data from a table to a file, or copy
data from a file into a table.
The *Import/Export data* dialog organizes the import/export of data through the
*Options* and *Columns* tabs.

:align: center
Use the fields in the *Options* tab to specify import and export preferences:
* Move the *Import/Export* switch to the *Import* position to specify that the
server should import data to a table from a file. The default is *Export*.
* Use the fields in the *File Info* field box to specify information about the
source or target file:
* Enter the name of the source or target file in the *Filename* field.
Optionally, select the *Browser* icon (ellipsis) to the right to navigate
into a directory and select a file.
* Use the drop-down listbox in the *Format* field to specify the file type.
Select:
* *binary* for a .bin file.
* *csv* for a .csv file.
* *text* for a .txt file.
* Use the drop-down listbox in the *Encoding* field to specify the type of
character encoding.

* Use the fields in the *Miscellaneous* field box to specify additional
information:
* Move the *OID* switch to the *Yes* position to include the *OID* column.
The *OID* is a system-assigned value that may not be modified. The default
is *No*.
* Move the *Header* switch to the *Yes* position to include the table header
with the data rows. If you include the table header, the first row of the
file will contain the column names.
* If you are exporting data, specify the delimiter that will separate the
columns within the target file in the *Delimiter* field. The separating
character can be a colon, semicolon, a vertical bar, or a tab.
* Specify a quoting character used in the *Quote* field. Quoting can be
applied to string columns only (i.e. numeric columns will not be quoted)
or all columns regardless of data type. The character used for quoting can
be a single quote or a double quote.
* Specify a character that should appear before a data character that matches
the *QUOTE* value in the *Escape* field.
Click the *Columns* tab to continue.

or exported:
* Click inside the *Columns to export/import* field to deselect one or more
columns from the drop-down listbox. To delete a selection, click the *x* to
the left of the column name. Click an empty spot inside the field to access
the drop-down list.
* Use the *NULL Strings* field to specify a string that will represent a null
value within the source or target file.
* If enabled, click inside the *Not null columns* field to select one or more
columns that will not be checked for a NULL value. To delete a column, click
the *x* to the left of the column name.
