db2 ? SQL0206N
SQL0206N "<name>" is not valid in the context where it is used.
Explanation:
This error can occur in the following cases:
* For an INSERT or UPDATE statement, the specified column is not a
column of the table, or view that was specified as the object of the
insert or update.
* For a SELECT or DELETE statement, the specified column is not a
column of any of the tables or views identified in a FROM clause in
the statement.
* For an assignment statement, the reference name does not resolve to
the name of a column or variable.
* When referencing a field in a row type variable, the reference name
does not resolve to the name of any field in the row type.
* For an ORDER BY clause, the specified column is a correlated column
reference in a subselect, which is not allowed.
* For a SELECT statement in a parameterized cursor constructor, the
reference to "<name>" does not match a column or in-scope variable.
Local variables and routine SQL parameters are not considered in
scope for parameterized cursors.
* For a standalone compound SQL (compiled) statement:
* The reference "<name>" does not resolve to the name of a column or
local variable that is in scope.
* The condition name "<name>" specified in the SIGNAL statement has
not been declared.
* When referencing a field in a row type variable, the reference
name does not resolve to the name of any field in the row type.
* For a CREATE TRIGGER,CREATE METHOD,CREATE FUNCTION or CREATE
PROCEDURE statement:
* The reference "<name>" does not resolve to the name of a column,
local variable or transition variable.
* The reference "<name>" resolves to the name of a local variable
that is not available in the current scope.
* The condition name "<name>" specified in the SIGNAL statement has
not been declared.
* When referencing a field in a row type variable, the reference
name does not resolve to the name of any field in the row type.
* For a CREATE TRIGGER statement:
* A reference is made to a column of the subject table without using
an OLD or NEW correlation name.
* The left hand side of an assignment in the SET transition-variable
statement in the triggered action specifies an old transition
variable where only a new transition variable is supported.
* For a CREATE FUNCTION statement with a PREDICATES clause:
* The RETURN statement of the SQL function references a variable
that is not a parameter or other variable that is in the scope of
the RETURN statement.
* The FILTER USING clause references a variable that is not a
parameter name or an expression name in the WHEN clause.
* The search target in an index exploitation rule does not match
some parameter name of the function that is being created.
* A search argument in an index exploitation rule does not match
either an expression name in the EXPRESSION AS clause or a
parameter name of the function being created.
* For a CREATE INDEX EXTENSION statement, the RANGE THROUGH clause or
the FILTER USING clause references a variable that is not a parameter
name that can be used in the clause.
* For a parameterized cursor variable reference, a local SQL variable
or SQL parameter referenced in the select statement used in the
definition of a parameterized cursor variable is not available in the
current scope.
The statement cannot be processed.
User response:
Verify that the names are specified correctly in the SQL statement. For
a SELECT statement, ensure that all the required tables are named in the
FROM clause. For a subselect in an ORDER BY clause, ensure that there
are no correlated column references. If a correlation name is used for a
table, verify that subsequent references use the correlation name and
not the table name.
For a CREATE TRIGGER statement, ensure that only new transition
variables are specified on the left hand side of assignments in the SET
transition-variable statement and that any reference to columns of the
subject table have a correlation name specified.
For a standalone compound SQL statement, CREATE FUNCTION, CREATE
PROCEDURE, or CREATE TRIGGER statement, verify that the columns or
variables are available in the scope of the current compound SQL
statement.
For a fullselect embedded in XQuery using the db2-fn:sqlquery function,
a reference within the fullselect must be one of the following: a column
in the context of the fullselect, a global variable, or a parameter
passed to the new SQL context using an additional argument of the
db2-fn:sqlquery function.
