Use the *Export Data Using Query* dialog to copy data to a file.
|
|
|
|
The *Export Data Using Query* dialog organizes the export of data through the
|
|
*General*, *Options* and *Query* tabs.

|
Use the fields in the *General* tab to specify export preferences:
|
|
|
|
* Enter the name of the target file in the *Filename* field.
|
|
Optionally, select the *Browse* 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 *Options* tab to specify additional information:
|
|
|
|
* 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.
|
|
* Use the *NULL String* field to specify a string that will represent a null
|
|
value within the source or target file.
|
|
|
|
Click the *Query* tab to continue.

Use the fields in the *Query* tab to write the query that will be exported:
|
|
|
|
* Use the *Export Data Query* field to specifies A SELECT, VALUES, INSERT, UPDATE,
|
|
DELETE, or MERGE command whose results are to be copied .
|
|
|
|
* Use *Force Quote columns* field to forces quoting to be used for all non-NULL
|
|
values in each specified column. NULL output is never quoted. This is a creatable
|
|
select control. If you would like to quote all columns then provide only '*' in
|
|
the field.
|
|
|
|
After completing the *Export Data Using Query* dialog, click the *OK* button to
|
|
perform the export. pgAdmin will notify you when the background
