+Special SQL Functions
+---------------------

+
+QBAR: Escape QFQ Delimiter
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SQL function QBAR(text) replaces "|" with "\\|" in `text` to prevent conflicts with the QFQ special column notation.
+In general this function should be used when there is a chance that unplanned '|'-characters occur.
+
+Example::
+
+    10.sql = SELECT CONCAT('p:notes|t:Information: ', QBAR(Note.title), '|b') AS _link FROM Note  
+
+In case 'Note.title' contains a '|' (like 'fruit | numbers'), it will confuse the '... AS _link' class. Therefore it's
+necessary to 'escape' (adding a '\' in front of the problematic character) the bar which is done by using `QBAR()`.
+
+.. _qmore-truncate-long-text:
+
+QMORE: Truncate Long Text - more/less
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The SQL function QMORE(text, n) truncates `text` if it is longer than `n` characters and adds a "more.." button. If the "more..."
+button is clicked, the whole text is displayed. The stored procedure QMORE() will inject some HTML/CSS code.
+
+Example::
+
+    10.sql = SELECT QMORE("This is a text which is longer than 10 characters", 10)
+
+Output:
+
+This is a `more..`
