Creates a record, sets fields to their default
values, and moves a copy of the record into the buffer.

Buffer object handle
Syntax
BUFFER-CREATE ( [ tenant-expression ] )
|
-
tenant-expression
- This parameter is useful only for a multi-tenant database, and primarily
one with a connection identity that has super tenant access. If the
user has a super-tenant connection identity and you do not specify
this parameter, the record you create is owned by the effective tenant.
If you do specify this parameter, you create a record owned
by the regular tenant identified by tenant-expression.
If
the user has a regular-tenant connection identity, and you specify this
parameter, tenant-expression must match the tenancy
of the connection identity. Otherwise, the statement raises ERROR.
If tenant-expression evaluates
to an integer, the value must be a valid tenant ID for a regular
tenant or zero (0) for the default tenant. If tenant-expression evaluates
to a character string, the value must be a valid tenant name for
a regular or "Default" for the default tenant.
Otherwise, the statement raises ERROR.
If Buffer object handle references
a buffer in a table that is not multi-tenant enabled, the method
raises ERROR.
Notes
- The
BUFFER-CREATE( ) method corresponds to the CREATE statement.
- When working with a partitioned table,
creating a record without initially setting the partition fields
to valid values may cause an error. See CREATE statement for
more details.
- When you pass tenant-expression, the AVM looks
up the tenant identity in the database with a share lock. The AVM waits
60 seconds to get the share lock and raises ERROR if it fails to
obtain the share lock in that amount of time. The AVM releases the
share lock immediately after successfully fetching the row. This
share lock is released even if the statement is called while in
the scope of a transaction.
