references to user-defined functions,
distinct types, and stored procedures. In
dynamic SQL, the SQL path is found in
the CURRENT PATH special register. In
static SQL, it is defined in the PATH bind
option.
SQL procedure
A user-written program that can be
invoked with the SQL CALL statement.
An SQL procedure is written in the SQL
procedural language. Two types of SQL
procedures are supported: external SQL
procedures and native SQL procedures.
See also external procedure and native
SQL procedure.
SQL processing conversation
Any conversation that requires access of
DB2 data, either through an application or
by dynamic query requests.
SQL Processor Using File Input (SPUFI)
A facility of the TSO attachment
subcomponent that enables the DB2I user
to execute SQL statements without
embedding them in an application
program.
SQL return code
Either SQLCODE or SQLSTATE.
SQL routine
A user-defined function or stored
procedure that is based on code that is
written in SQL.
SQL schema
A collection of database objects such as
tables, views, indexes, functions, distinct
types, schemas, or triggers that defines a
database. An SQL schema provides a
logical classification of database objects.
SQL statement coprocessor
An alternative to the DB2 precompiler
that lets the user process SQL statements
at compile time. The user invokes an SQL
statement coprocessor by specifying a
compiler option.
SQL string delimiter
A symbol that is used to enclose an SQL
string constant. The SQL string delimiter
is the apostrophe (’), except in COBOL
applications, where the user assigns the
symbol, which is either an apostrophe or
a double quotation mark (″).
SRB See service request block.
stand-alone
An attribute of a program that means that
it is capable of executing separately from
DB2, without using DB2 services.
star join
A method of joining a dimension column
of a fact table to the key column of the
corresponding dimension table. See also
join, dimension, and star schema.
star schema
The combination of a fact table (which
contains most of the data) and a number
of dimension tables. See also star join,
dimension, and dimension table.
statement handle
In DB2 ODBC, the data object that
contains information about an SQL
statement that is managed by DB2 ODBC.
This includes information such as
dynamic arguments, bindings for
dynamic arguments and columns, cursor
information, result values, and status
information. Each statement handle is
associated with the connection handle.
statement string
For a dynamic SQL statement, the
character string form of the statement.
statement trigger
A trigger that is defined with the trigger
granularity FOR EACH STATEMENT.
static cursor
A named control structure that does not
change the size of the result table or the
order of its rows after an application
opens the cursor. Contrast with dynamic
cursor.
static SQL
SQL statements, embedded within a
program, that are prepared during the
program preparation process (before the
program is executed). After being
prepared, the SQL statement does not
change (although values of variables that
are specified by the statement might
change).
storage group
A set of storage objects on which DB2 for
z/OS data can be stored. A storage object
can have an SMS data class, a
management class, a storage class, and a
list of volume serial numbers.
