Change lock type on live table

Question

I have 2 ASE Server. One is for live, one is for dev.
There is a table mytab, which lock type is DataPage. I want to change it to DataRow.
On dev server, I use tool to get the script to change the type is simple. like:
USE mydb
go
setuser 'dbo'
go
alter table mytab lock DATAROWS
go
but on live production, I get the script is different. It is trying to delete all pk, fk, sp, trigger related to mytab and create a another table mytab23434,....
What is the reason why it create a so messy script only for change the lock type.
So I want to know if it is safe just run alter table mytab lock DATAROWS on live.
If I use Sybase central and try to get the script to change lock type on both dev and live, they are simple and same:
USE mydb
go
setuser 'dbo'
go
alter table mytab lock DATAROWS
go
Because I am going to do it on live. So want to confirm it is safe just to run:
alter table mytab lock DATAROWS

Answer 1

Thanks, Mark. I worry about data loss. If no data loss, it is my defined 'safe' because when I try it on dev server, I fond out weird thing:
The rows in the table is more than before after change lock type from DataPage to DataRow.
With my test, mytab has 637,255 row. After change lock type, the row number is 637,282. So I am afraid of doing it on production!
With command ALTER TABLE dbo.mytab LOCK DATAROWS,   I got message as:
Warning: Row size (3839 bytes) could exceed row size limit, which is 1964 bytes.
Non-clustered index (index id = 2) is being rebuilt.
Non-clustered index (index id = 26) is being rebuilt.
Warning: The schema for table 'mytab' has changed. Drop and re-create each trigger on this table that uses the 'if update(column-name)' clause.
