Our organization is relatively new to Oracle but fairly seasoned with SQL Server
development. We have a few questions we need to understand to make the
transition as quickly as possible. Please respond directly via email as I do
not read this newsgroup regularly,

SQL*Plus related
How do I tell the Server to return only a fixed number of rows in response to a
query.
In isql (Sybase) I would say
set rowcount 10
select fld1 from table1 where fld2 > 100
This would return the first 10 rows that fulfilled the condition.
How do I achieve the same in SQL*Plus. There does not seem any
environment variable that I can set.
OCI related
OCIStmntExecute( ) returns the status of executing a SQL command.
Is there a call to find the number of result rows before doing a fetch ?
( equivalent to a Sybase DBCOUNT () ) which would facilitate doing a
single memory allocation for storing the results
Oracle Database Server - Datatypes related
User defined types in Oracle refer to composite fields.
In Sybase they are more like typedefs in C/C++
e.g I would define a user defined type ut_zip as char(6)
This way whenever I had addresses the zip field would be of type ut_zip.
This facilitated a single point of change to the zip fields and also
maintenance / searching the database for zip fields.
How can I achieve the same in Oracle ?
