code page

The code page information can be converted into XML format documents, easy to operate.

A substitution character is always converted into another substitution character in any other code page.

Therefore, all XML parsing, serialization, query execution, and comparisons must take place in a Unicode code page.

Select the code page, text layout, file type, and any other relevant parameters that match the target text file to be created.

This XML document can now be inserted into a table with an XML column irrespective of the database code page.

A code page can be defined as a table with a mapping of alphanumeric code and its binary representation.

The previous sections showed how the code page value can be determined and changed for an application or database in different platforms.

Setting this variable to 1208 (UTF-8) allows DB2 to communicate with the client as if it was operating in code page 1208.

When the locale code page changes, the behavior of the locale-dependent set of functions changes to that dictated by the chosen code page.

Binding XML into a BLOB host variable can help to avoid substitution characters as DB2 does not perform code page conversion on BLOB data.

All SQL comparisons, SQL query execution, and SQL casting takes place in the database code page.

Substitution characters may be introduced during serialization if code points cannot be rendered in the database code page.
