We found that a foreign key have been added on the replicated table.<br><br>Instead of using DDL execute script, I am used to do <br><br>- removing table from replication<br><br>- doing my altered queries<br><br>- putting back table into replication.<br><br>Since the replicated table has a small size and since my altered query is <br><br>alter table ... add constraint ... foreign key ... references ....(....);<br><br>I asked myself if the 3 steps above are mandatory ( or "DDl execute script") or if I can execute my altered query directly?<br><br>Thanks for letting me know.<br><br>Kind regards.<br><br>David.<br><div><br></div></div></body></html>
