`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.

|
|
|
|
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 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.

|
|

|
|
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
|
|
