After defining a schema, you can store it in a table before using it for validating XML values. In this example, the schema document is stored in the table schematab, which is defined as the following:

CREATE TABLE schematab (
   schemaid VARCHAR(32),
   schemaContent XML )
   PRIMARY INDEX (schemaid);

The schema.txt file used in the .IMPORT statement below has the following format:

customerschema.xsd|customerschema.xsd

Use this statement to store the schema in the schematab table:

.IMPORT VARTEXT '|' LOBCOLS=1 FILE=schema.txt
USING (fxsd XML AS DEFERRED, xmlid varchar(32))
INSERT into schematab values(:xmlid, :fxsd);
