INSERT INTO (SELECT tname FROM TAB where tname='table name') VALUES('a');

I think you will have to do some dynamic SQL, here is a URL on this site of a document that may help.

CREATE PROCEDURE ABC (P_TABLE_NAME VARCHAR2) AS
SQL VARCHAR2(4000);
BEGIN
SQL := 'INSERT INTO '||P_TABLE_NAME||' VALUES (''A'')';

EXECUTE IMMEDIATE SQL;
END;
