The ISQL - Input screen is a free-mode editor (see Editing within the Natural Tools for DB2) which provides a functionality similar to the one of the Software AG Editor. Using the editor you can enter or edit SQL statements via editor main and line commands. You can execute the SQL statements immediately from within the editor by pressing PF4 (Exec), or you can save them as an SQL member (text object) in a Natural library for later execution.
For information on the PF keys available, see PF Key Settings.
Anmerkung:
The PRINT command is not available in
the SQL input screen.
Apart from the editor main and line commands, SQLCODE maintenance commands are also available to maintain SQL members in a Natural library; see Global Maintenenance Commands. With these maintenance commands, input members can be listed, retrieved, saved in a Natural library, copied, and purged. They are entered in the command line of the input screen.
You can also obtain a list of the available maintenance commands by entering the help character, that is, a question mark (?), in the command line of the input screen. A window is displayed from which the desired command can be selected. The window can be scrolled forwards by pressing PF8, or backwards by pressing PF7.

|
|
Selects all tables with the specified creator (optional) and
name.
For both If you specify asterisk notation only, all existing tables are selected. If you specify a table name without a creator, all tables with the specified name are selected, regardless of their creator. |

From the data output screen you have access to output data members
only. Output members consist of data retrieved from the database as a result of
executed SQL statements. These data can be browsed and saved for later use as
output members on the Natural system file FUSER. In addition to
the data retrieved from the database, output members also contain DB2 status
information, and the executed SQL member.
If you execute an SQL statement, the results are automatically shown on the output screen. Thus, you can enter the interactive SQL output screen also by executing an SQL statement from the input screen. From the output screen you can return to the input screen by pressing PF3 (Exit).
For information on the other PF keys available, see PF Key Settings.
The maintenance commands available for output members can be displayed and selected in a window, too; see Global Maintenenance Commands. The window is invoked by entering the help character, that is, a question mark (?), in the command line of the output screen.

From the output member selection list, output members can be selected
for display by marking them with an S.
If the list has been invoked by a PURGE
command, members can be purged by marking them with a P.
SQL input members (text objects) can only be accessed from the ISQL - Input screen. They are executed from the input screen against DB2 by pressing PF4 (Exec).
After execution, the data output screen appears which contains the results of the executed SQL member.
If an SQL member consists of more than one SQL statements, the individual statements must be separated by a semicolon. They can be executed one by one or all together at the same time.
To choose the form of execution, a window is provided which can be invoked by pressing PF2 (Setup).

Below is information on the options provided:
After each SQL statement the output screen is shown. From the output
screen, you can either execute the next SQL statement from the input screen by
pressing PF4 (Next), or skip the remaining SQL statements and return
to the input screen immediately by pressing PF3 (Exit).
All statements are executed immediately one after the other. The output screen shows the results of all statements together.
Statements containing cursor names, host variables, or parameter markers cannot be executed with interactive SQL. Also not executed are statements available as embedded SQL only; that is, statements whose functions are automatically performed by Natural.
These statements are:
CLOSE |
CONNECT |
DECLARE |
DELETE WHERE CURRENT OF CURSOR |
DESCRIBE |
EXECUTE |
FETCH |
INCLUDE |
OPEN |
PREPARE |
SELECT INTO |
SET
host-variable |
SET CURRENT PACKAGESET |
UPDATE WHERE CURRENT OF CURSOR |
WHENEVER |
If you select Automatic Commit/Rollback, each
modification of the database is automatically either committed or rolled back,
depending on whether all the SQL statements involved execute successfully. If
so, an SQL COMMIT WORK command is executed; if not,
an SQL ROLLBACK command backs out all database
modifications since the last commit point.
If you select Optional Commit/Rollback, a window is invoked after each SQL statement, offering you the option to either commit or roll back the resulting database modifications shown on the screen.
Anmerkung:
Since under CICS and IMS TM each terminal I/O results in a
SYNCPOINT, the optional commit/rollback feature only applies in a
TSO environment.
In all environments, you can include SQL
COMMIT and ROLLBACK commands in your
input member, too. Under CICS and IMS TM, however, these commands are
translated into the corresponding TP-monitor calls.
The text that is to be shown for NULL values can be
specified here; the default string is ---.
If you enter multiple SQL statement, they need to be separated. The default statement termination character is the semi-colon (;).
Limits the length for a single column to
n characters. This limit only applies
to character data. DATE, TIME, or
NUMERIC columns are not truncated. The value 0
indicates that no limit exists.
Limits the number of rows returned by one
SELECT statement.
The value 0 indicates that no limit exists.
Sets a limit for the DB2 cost estimate.
SELECT statements
which exceed this limit are not executed. The value 0 indicates
that no limit exists.
For SELECT
statements, you can specify that every
n data lines a header line is inserted
with the names of the selected columns. If
n is set to 0, only one
header line is displayed at the top of the data.
The record length (n) for the
output session can be specified. If the specified record length is smaller than
the record length of the output data, the output records are truncated
accordingly. The truncation of records is indicated by a greater than character
(>) as the leftmost character in the first line beneath each header line.
The default value for n is 250
bytes.
The following PF-key settings apply to the ISQL - Input screen:
| Key | Setting | Function |
|---|---|---|
| PF2 | Setup | Invokes a window with further processing options. |
| PF4 | Exec | Executes the SQL member (text object) currently on the input screen. |
| PF5 | Rfind | Repeats the last executed FIND

|
| PF6 | Rchan | Repeats the last executed CHANGE
command.
|
| PF7 | - | Scrolls the display one page backward. |
| PF8 | + | Scrolls the display one page forward. |
| PF9 | Outpu | Invokes the output member (text object) selection list directly from within the input screen. |
Apart from PF2 (Setup), PF4 (Exec), and PF9 (Outpu), the same PF-key settings apply to the ISQL - Output screen, too. In addition, the following PF-key settings are available:
| Key | Setting | Function |
|---|---|---|
| PF4 | Next |
Executes the next SQL statement if an SQL member consists of
more than one statement, and if you have chosen to execute them one after the
other. |
| PF10 | < | Scrolls the display of the output screen to the left. |
| PF11 | > | Scrolls the display of the output screen to the right. |
Results from interactive SQL are unloaded and written to a data set
referred to by DD name CMWKF01 in batch mode using the
UNLDDATA command.
CMWKF01 should be of variable record format; the record
length depends on the size of the SQL output member (text object) and can range
from 250 to 4000 bytes.
To unload results from interactive SQL
Logon to the Natural system library SYSDB2.
