hi,
You mean if I have 10 tables under the same database, once I locked one
table with the statement "lock tables table1 read", then the other
tables(the rest of table except table1) will not be allowed to access by me
or other people, even for reading......unless I unlock table1. Is that what
you mean.??
Thank you
Mark
