Why do I receive the error "??? Undefined function or variable 'getTheMetaData'." when I select certain tables using the Visual Query Builder in MATLAB?

I am having some problems using the Matlab Database toolbox to access an Oracle database. In the Visual Query builder, there are some tables from the database for which I cannot see the fields. When I select those table in the table list I get the following error messages:

 ??? Undefined function or variable 'getTheMetaData'.

 Error in ==> D:\MATLAB6p5\toolbox\database\database\@cursor\columnnames.m

 On line 46  ==>   md = getTheMetaData(cursor.Fetch);

 Error in ==> D:\MATLAB6p5\toolbox\database\vqb\querycallbacks.m

 On line 749  ==>       tmp = columnnames(ex);

 ??? Error while evaluating uicontrol Callback.

When I try to get the fields from the table using the following code:

db_connection = database('enrg','','') ;

query1 = 'select * from GEODE0310 where scn =1 and poste =1;' ;

cursor1 = exec(db_connection,query1) ;

message1 = cursor1.Message ;

message1

 message1 =

To resolve this problem, create a synonym for the table. Also, specify the table in lower case or enclose it in double quotes:

query2 = 'select * from "AREAS" ;';
