Create an import task

1. Log on to ODC and go to the management page of the target connection. In the top navigation bar, click Task Center. In the Task Center panel, click + on the right side of Import to pop up the new import task panel

   

2. In the Create Import Task panel, specify the import format.

   

   As shown in the preceding figure, ODC supports batch import of CSV Files, SQL Files, and ZIP Files. You can select the desired file format from the Import Format drop-down list. For more information about formats, see Export and import formats.

   Note

   • If you select CSV Files for Import Format, you can skip the values of the column header in the first row.

   • If you select ZIP Files for Import Format, you can import single or multiple tables and skip existing structures.

3. Upload the file to be imported

   Click the file pool to go to the file explorer and select the file to be imported. You can also directly drag the file to the file pool to upload it. The format of the uploaded file must be the same as that of the value you specified for Import Format. Upload files suffixed with .zip if you have selected ZIP Files for Import Format, upload files suffixed with .sql if you have selected SQL Files for Import Format, and upload files suffixed with .csv if you have selected CSV Files for Import Format.

4. Specify the file encoding

   ODC supports the following encoding standards: ASCII, ISO-8859-1, GB2312, GBK, GB18030, Unicode (UTF-8), Unicode (UTF-16), Unicode (UTF-32), and BIG5. You can select the encoding standard from the File Encoding drop-down list.

5. Go to the Import Settings panel

   Click Next: Import Settings to specify file import settings and the sys tenant account.

6. Specify Import Content

   

   You must specify this parameter when you select ZIP Files for Import Format. ODC supports Import Data Only, Import Schema Only, and Import Schema and Data. Import Schema Only imports the definition statements of the target object. You can select the import content from the Import Content drop-down list.

7. Select a database

   Select the database to which the data object is to be imported. The name of the database connection to which the task belongs is also displayed.

8. Specify Import Data Settings

   If you select ZIP Files for Import Format and Import Data Only or Import Schema and Data for Import Content, this option must be specified. You need to specify the following fields:

   • Clear Data Before Import: If you select this option, the original data in the destination object is cleared during data import.

   • Batch Commit Quantity: You can click Advanced next to Export Data Settings to specify this field. After you specify this field, a COMMIT statement is executed when the number of exported data rows reaches the specified quantity.

   • Skipped Data Type (Optional): You can specify the data types to be skipped during data import. The data types that can be skipped are different in MySQL and Oracle modes. You can select multiple data types.

9. Specify Import Schema Settings

   You cannot specify this field if you select Import Data Only for Import Content. This field involves operations on schemas that already exist. If you select Skip, the system skips the schema definition statement in the file to be imported and directly imports the data. The original data in the object is retained. If you select Replace, the system executes the schema definition statement in the file to be imported to re-create an object and replace the original one. Data in the original object is cleared.

10. Specify Task Error Handling Method and the execution method

    • Select Execute immediately or Timed execution.

    • ODC supports two error handling methods: Abort Task and Ignore Error and Continue. You need to select the handling method as required.

11. Retain Current Configuration

    Check Retain Current Configuration to keep the current part of the data file and structure file configuration.

12. Generate an import task

    After you specify all preceding information, you can click Submit in the lower-right corner of the panel to create an import task.
