stored procedure
A user-written application program that
can be invoked through the use of the
SQL CALL statement. Stored procedures
are sometimes called procedures.
string See binary string, character string, or
graphic string.
strong typing
A process that guarantees that only
user-defined functions and operations that
are defined on a distinct type can be
applied to that type. For example, you
cannot directly compare two currency
types, such as Canadian dollars and U.S.
dollars. But you can provide a
user-defined function to convert one
currency to the other and then do the
comparison.
structure
v A name that refers collectively to
different types of DB2 objects, such as
tables, databases, views, indexes, and
table spaces.
v A construct that uses z/OS to map and
manage storage on a coupling facility.
See also cache structure, list structure,
or lock structure.
Structured Query Language (SQL)
A standardized language for defining and
manipulating data in a relational
database.
structure owner
In relation to group buffer pools, the DB2
member that is responsible for the
following activities:
v Coordinating rebuild, checkpoint, and
damage assessment processing
v Monitoring the group buffer pool
threshold and notifying castout owners
when the threshold has been reached
subcomponent
A group of closely related DB2 modules
that work together to provide a general
function.
subject table
The table for which a trigger is created.
When the defined triggering event occurs
on this table, the trigger is activated.
subquery
A SELECT statement within the WHERE
or HAVING clause of another SQL
statement; a nested SQL statement.
subselect
That form of a query that includes only a
|
SELECT clause, FROM clause, and
|
| optionally a WHERE clause, GROUP BY
clause, HAVING clause, ORDER BY
|
clause, or FETCH FIRST clause.

substitution character
A unique character that is substituted
during character conversion for any
characters in the source program that do
not have a match in the target coding
representation.
subsystem
A distinct instance of a relational database
management system (RDBMS).
surrogate pair
A coded representation for a single
character that consists of a sequence of
two 16-bit code units, in which the first
value of the pair is a high-surrogate code
unit in the range U+D800 through
U+DBFF, and the second value is a
low-surrogate code unit in the range
U+DC00 through U+DFFF. Surrogate
pairs provide an extension mechanism for
encoding 917 476 characters without
requiring the use of 32-bit characters.
SVC dump
A dump that is issued when a z/OS or a
DB2 functional recovery routine detects
an error.
sync point
See commit point.
syncpoint tree
The tree of recovery managers and
resource managers that are involved in a
logical unit of work, starting with the
recovery manager, that make the final
commit decision.
synonym
In SQL, an alternative name for a table or
|
| view. Synonyms can be used to refer only
to objects at the subsystem in which the
|
synonym is defined. A synonym cannot
|
| be qualified and can therefore not be used
by other users. Contrast with alias.
