+ <code class="command">DECLARE STATEMENT</code> declares an SQL statement identifier.
+ SQL statement identifier can be associated with the connection.
+ When the identifier is used by dynamic SQL statements, the statements
+ are executed using the associated connection.
+ The namespace of the declaration is the precompile unit, and multiple
+ declarations to the same SQL statement identifier are not allowed.
+ Note that if the precompiler runs in Informix compatibility mode and
+ some SQL statement is declared, "database" can not be used as a cursor
+ name.
