Exporting Data

Syntax

1

INSERT INTO [Foreign table name] SELECT * FROM [Source table name];

Examples

• Example 1: Export data from table product_info_output to a data file through the product_info_output_ext foreign table.

  1	INSERT INTO product_info_output_ext SELECT * FROM product_info_output;

  If information similar to the following is displayed, the data has been exported.

  1	INSERT 0 10

• Example 2: Export part of the data to a data file by specifying the filter condition WHERE product_price>500.

  1	INSERT INTO product_info_output_ext SELECT * FROM product_info_output WHERE product_price>500;

• The directory to be used for data storage must be empty, or the export will fail.
• Data of a special type, such as RAW, is exported as a binary file, which cannot be recognized by the import tool. You need to use the RAWTOHEX() function to convert it to the hexadecimal format before export.
