JDBC Adapter Quoting of String

Question

Hi everybody!
I am posting data to a JDBC Receiver adapter using the JDBC adapter's XML format. I have configured the logging of the adapter to show the SQL commands issued to the adapter, since I received some strange errors from the database.
I now find entries like:
INSERT INTO  xxx (field1, field2, field3) VALUES (value1, , value3)
Notice the "missing" value2 - the field's value is a space character (" "). However, I actually wanted to quote the values in this field, since this SQL command of course gives a syntax error because of the two consecutive commas...
How can I quote strings in this SQL command?

Hi,
I don't know if I stated my problem clearly enough... Here is the XML document I post to the JDBC adapter:
<root>
  <insert>
    <xxx action="INSERT">
      <field1>value1</field1>
      <field2> </field2>
      <field3>value1</field3>
    </xxx>
  </insert>
</root>
(note the blank character for field2's value). If I understand your answer correctly, I should use the following instead:
<root>
  <insert>
    <xxx action="INSERT">
      <field1>'value1'</field1>
      <field2>' '</field2>
      <field3>'value1'</field3>
    </xxx>
  </insert>
</root>
This is somewhat inconvenient, since there might be <b>NULL</b> values as well and I'd have to code manymany <b>if</b> statements and <b>mapWithDefaults</b>, then. I was wondering if there is something like the config setting "Interpretation of Empty String Values" for NULL values, some switch I set globally in order to <i>always</i> quote a string...
