Day 17

Day 17


1:

To create a new table by importing IXF data, which import mode should you use?

A1:

You must use the CREATE import mode to create a new table when importing IXF data.

2:

If you want to create a new table, what format should you use? Would you use the Load Wizard or the Import Wizard to create a new table?

A2:

Integrated exchange format (IXF) is used to create a new table; the DEL, ASC, and WSF formats can be used only to import data into an existing table. IXF format is the format used by database managers. Load doesn't support creating a new table; the table must exist before you can load data into it. To create a new table, use the Import utility.

3:

How do you export only a subset of the data in a table?

A3:

Click the Columns tab in the Export dialog box to specify only a subset of the columns to export. Exporting a subset of columns is supported only when using WSF or IXF formats.

4:

What must take place before you can save a copy of the changes when using the Load Wizard?

A4:

Forward recovery must be turned on to enable you to save a copy of the changes when using the Load utility. On the Copy Options page of the Load Wizard, specify that a copy of the changes be saved.
