Cause: In a precompiled program, the
DECLARE TABLE statement was mistakenly used inside an embedded PL/SQL block.
If an embedded PL/SQL block refers to a database table that does not yet
exist, use the DECLARE TABLE statement to tell the precompiler what the table
will look like. However, DECLARE TABLE statements are allowed only in the host
program.
Action: Move the DECLARE TABLE statement
outside the embedded PL/SQL block. If you want a variable that can store an
entire row of data selected from a database table or fetched from a cursor or
cursor variable, use the %ROWTYPE attribute.
