Natural System Error Messages 0701-0750

Text

Invalid assignment clause in SQL UPDATE statement.

Explanation

The specified column does not exist in the referenced table that is
to be updated; or the equal sign (=) after the column specification
is missing; or the scalar-expression after the equal sign contains
an error.

Action

Correct error in program.

Text

With a view, only 'SET *' is allowed in SQL UPDATE.

Explanation

When a view is referenced in an SQL UPDATE statement,
'SET *' must be specified; an explicit assignment list is
only allowed and required when a DDM is referenced in the
SQL UPDATE statement.

Action

Correct error in program.

Text

Invalid range-variable specified in SQL INSERT/DELETE.

Explanation

In an SQL INSERT or SQL DELETE statement, an invalid range-variable
(identifier) has been specified after the DDM (table) name.

Action

Correct error in program.

Text

Opening or closing parenthesis missing in INSERT.

Explanation

In an INSERT statement, either the list of field names or
the list of values is not correctly enclosed in parentheses.

Action

Correct error in program.

Text

Field to be INSERTed is not in specified DDM/table.

Explanation

The field specified in the column list of the INSERT statement
does not exist in the referenced DDM/table.

Action

Correct error in program.

Text

Invalid value specified in VALUES clause of INSERT.

Explanation

Values specified in the VALUES clause of an INSERT statement must
be one of the following:
- the keyword 'NULL' (to assign a null value);
- a special register (USER, CURRENT TIMEZONE, CURRENT DATE,
                     CURRENT TIME, CURRENT TIMESTAMP);
- a constant or a user-defined variable.

Action

Correct error in program.

Text

VALUES clause missing or invalid SELECT clause specified.

Explanation

In an INSERT statement, either a valid VALUES clause or a
valid SELECT clause must be specified.

Action

Correct error in program.

Text

Incorrect usage of index range field.

Explanation

1) When an array range is used as a parameter in an
   SQL statement (e.g. SELECT, INSERT), the lower
   index of the specified range must be 1.
   Example:
     INSERT INTO table (col) VALUES (arr(1:3))
2) The data type of a field specified with an index range
   must be alphanumeric or binary.
   In the example of 1) arr must be defined as A or B.
3) Arrays must be one-dimensional. That is, arrays that are
   defined in DEFINE DATA as (A10/1:3;1:5) are not permitted.
4) Variable index ranges, such as (1:I), are not permitted.

Action

Check syntax and correct error.

Text

The CLSID was not found in the registry (DCOM code ...).

Explanation

The CLSID associated with the given class name was not found
in the registry.

Action

Make sure that  the class name used in the CREATE OBJECT statement
is correctly registered.

Text

The object could not be created (DCOM code ...).

Explanation

The object of the class specified in the CREATE OBJECT statement
could not be created. Common reasons are:

1) The class is not correctly registered.
2) You are not authorized to create the object.
3) The specified node does not exist or could not be reached.

Action

Check if one of the above conditions applies.

Text

A library name must be specified for Natural Security.

Explanation

If Natural Security is installed, the system commands REGISTER and
UNREGISTER can only be used for a single library. Therefore the
library name must not be '*'.
The library name can be omitted when applying the commands to all
classes of the current logon library. If the commands are to be
applied to classes in another library, the name of this library has
to be specified.

Action

Either omit the library name or enter the name of an existing library.

Text

Internal error (DCOM code ...).

Explanation

An internal error occurred because of one of the following reasons:

1) A string could not be converted from Ansi to Unicode.
2) An automation interface function failed to execute.
3) The default dispatch interface was not returned during
   object creation.
4) Analyzing the type information failed.
5) A dispatch interface could not be retrieved.

Action

Check if the used class is correctly registered.

Text

Registry entry could not be changed.

Explanation

Natural could not change or create entries in the system registry
which are needed to register the DCOM class.

Action

Check, if you have permission to change the system registry.
If this is not the case, you cannot register classes.

Text

Registry entry could not be deleted.

Explanation

Natural could not delete entries in the system registry
which are no longer needed when the DCOM class is unregistered.
1. Check if you have permission to delete entries from the
   system registry. If this is not the case, you cannot
   unregister classes.
2. Check if the CLSID of the class to be unregistered
   was changed after registering the class. In this case it is not
   possible to find the class in the registry.

Action

See explanation.

Text

Registry entry could not be read.

Explanation

Natural could not read entries in the system registry,
which is needed to register/unregister the DCOM class.

Action

Check, if you have permission to read the system registry.
If this is not the case, you cannot register/unregister the DCOM class.

Text

Internal error during registration.

Explanation

Internal error during registration.

Action

Unregister the class first and try to register it again.

Text

Registration files could not be created correctly.

Explanation

It was not possible to create the server and client
registration files (.reg) for the class.

Action

Check, if you have permission to create these files.

Text

DCOM server message: ....

Explanation

The DCOM server, which was called by the Natural client,
returns the message displayed above.

Action

None.

Text

INCDIR error: ....

Explanation

This message appears only if compiler option CHKRULE=ON is set.
During compilation, the DDM and field names referenced in INCDIR
statements are checked for existence. If either the DDM or the field
cannot be found, this message is issued.
INCDIR statements are automatically created if a database field is
included in a map. When the map is catalogued, these instructions will
effect an automatic incorporation of processing rules which might
exist for this field on Predict.

Action

1) Deactivate the message with CHKRULE=OFF.
2) Correct the DDM/field name in the INCDIR statement.

Text

Interactive I/O not possible in server environment.

Explanation

An attempt was made to execute an interactive I/O
(I/O to report 0), while Natural is acting as a server.

Action

Check and correct the program. Input data for the Natural INPUT
statement may be supplied via the Natural stack. Any output to
report 0 may be redirected using the MAINPR parameter.

Text

Invalid object handle used.

Explanation

An object handle can only be used after the object has been
created with a CREATE OBJECT statement, or after a valid handle
has been assigned to it.

Action

Make sure that the object has been successfully created before
it is used in a SEND METHOD statement or property access.

Text

Invalid placement of ... statement.

Explanation

An invalid statement has been specified in the current Natural object.
Possible reasons are, for example:
1. A DEFINE CLASS statement may only be specified in a
   Natural class object and only specified once per class object.
2. The first statement of a Natural function object must be
   DEFINE FUNCTION ... END-FUNCTION.
3. An END statement must not be used in a copycode object.

Action

Check the placement of the statement or check the object type.

Text

Invalid ... name specified.

Explanation

In a DEFINE CLASS statement the following rules apply to various names:
1. The class, interface, property or method name must not have more
   than 32 characters.
2. The class name may contain periods. Each identifier separated by a
   period must conform to the naming conventions for user-defined
   variables.
3. Interface, property or method names must conform to the naming
   conventions for user-defined variables.
   The interface name must not be identical to the class name.
4. The copy code or subprogram name must not have more than 8
   characters.

Action

Check the name and correct error.

Text

... name is not defined.

Explanation

In a PROPERTY statement
- the interface is not defined or
- the property name is not defined for the interface specified.
In a METHOD statement
- the interface name is not defined or
- the method name is not defined for the interface specified.

Action

Check the name and correct error.

Text

Keyword ... expected.

Explanation

The appropriate keyword is expected.

Action

Check the keyword and correct error.

Text

... name already defined.

Explanation

The interface name is not unique in the specified class or
the property or method name is not unique for the specified interface.

Action

Check the name and correct error.

Text

Property and assigned object var. not data-transfer compatible.

Explanation

The format/length specifications of the property and the assigned object
variable are not data-transfer compatible.
If the attribute READONLY is specified, the rule for data transfer
of the object variable as sending field and the property as receiving
field apply. Otherwise the data transfer rules for the property
and the assigned object variable as sending and receiving fields apply.

Action

Check the format/length specifications and correct error.

Text

No object variable assigned to property ....

Explanation

No object variable is assigned to the property.

Action

Assign an object variable to the property.

Text

Invalid globally unique ID specified.

Explanation

The specified value is not a valid globally unique ID.

Action

Check the value of the valid globally unique ID and correct error.

Text

The type information could not be retrieved ....

Explanation

In certain situations Natural needs type information about a
class to use it. The type information for the class could not
be found. A common reason is that the class is not correctly
registered on the server side.

Action

Make sure that the class is correctly registered and type
information exists.

Text

The interface ... was not found.

Explanation

The specified interface was not found in the object's
type information.

Action

Check the specified interface name.

Text

The method or property was not found (DCOM code ...).

Explanation

The specified method or property was not found in any of the
object's interfaces.

Action

Check the specified interface name (if any), the method or the
property name.

Text

The Natural object of class ... could not be created.

Explanation

With the class name specified in the CREATE OBJECT statement it
was not possible to create the object. A possible reason is that
the corresponding Natural class module was not found at the place
where it was registered.

Action

Check the class name used in the CREATE OBJECT statement and check
if the corresponding Natural class module is available.

Text

The method or property was not found.

Explanation

The specified method or property was not found in any of the
object's interfaces.

Action

Check the specified interface name (if any), the method or the
property name.

Text

A class with the same ... ... already exists as member ....

Explanation

You have used a class name which already exists in another class
module. The class names within a library must be unique.

Action

Change the class name.

Text

READONLY property ... must not be modified.

Explanation

If a property is declared as read-only, it must not be modified.

Action

Correct error in program.

Text

Invalid dispatch ID of ... ... in interface ....

Explanation

Methods and properties of classes have numeric identifiers,
called dispatch IDs, assigned. Normally these IDs
are assigned internally and automatically by Natural. If you
explicitly assign an ID to a method or property using the ID
clause, you have to assign the numbers uniquely
per interface. Dispatch IDs must be positive integer values.

Action

Assign a different ID to ensure uniqueness and correct format,
or do not assign an ID at all.

Text

No globally unique ID defined for interface ... of class ....

Explanation

The globally unique ID for the given interface is missing in the
Natural class definition. The ID is needed to enter information
for this interface in the registry.

Action

Define a globally unique ID for the interface.

Text

Type Library creation for class ... failed.

Explanation

The type library (.TLB) which is created during registration
of a Natural class in the Natural etc directory could not
be created. A possible reason is that a type library for the given
class already exists and has been opened by another tool. So Natural
cannot modify it.

Action

Check, if the type library is being used by another tool.

Text

No registry information entered for ....

Explanation

If a Natural class is to be accessible with DCOM, it
must be entered in the registry. If the class is to be
used only locally in Natural, this is not necessary.

Action

If you do not want to use the class with DCOM, you can ignore this
error message. Otherwise, define a valid ID for the class and define at
least one interface for the class.

Text

Conflicting number of parameters in SEND METHOD.

Explanation

The number of parameters which are specified with the SEND METHOD
statement must be identical to both:
  - the number of parameters, that are defined in the method,
  - the number of parameters, that are declared in the
    method declaration of the DEFINE CLASS statement.

Action

Check the parameter definitions in the class module, in the method
and the parameters in the SEND METHOD statement.

Text

Error during conversion of parameter ... in SEND METHOD.

Explanation

The parameter could not be converted to an appropriate
VARIANT format, or the VARIANT format returned from the
server could not be converted to an appropriate Natural format.

Some possible reasons are:
- A Natural variable of format 'C' cannot be passed
  as a method parameter.
- Arrays passed as arguments must match the corresponding
  method parameter in number of dimensions and number of
  occurrences per dimension.

Action

Consult the data conversion rules in the NaturalX documentation.

Text

Class name ... already defined in the registry.

Explanation

The class cannot be registered, because a class with the same
name but a different CLSID has been found in the system registry.

Action

Change the class name so that it is unique.

Text

No classes are registered under server ID ....

Explanation

The UNREGISTER command was used to unregister all classes that are
registered under a given server ID, or under the current server ID.
Currently there are no classes registered under this server ID.

Action

None.

Text

Error during conversion of property value or return value.

Explanation

The property value or return value could not be converted
to an appropriate VARIANT format, or the VARIANT format passed
back from the server could not be converted to an appropriate
Natural format.

Some possible reasons are:
- A Natural variable of format 'C' cannot be passed
  as property value or received as return value.
- Arrays passed as property value or received as return value
  must match the corresponding property or return parameter
  in number of dimensions and number of occurrences per dimension.

Action

Consult the data conversion rules in the NaturalX documentation.
