SQLRPGLE Select Statement for db2 in iSeries (AS400) - Fetch using Cursor In order to create an RPGLE source member that can use embedded SQL, you must use a source type of SQLRPGLE. To compile an SQLRPGLE source member, use the 'Create SQL ILE RPG Object' (CRTSQLRPGI) command. Buy parallels 11 for mac.

Www.go4as400.com - A programming guide to learn AS400. Toggle navigation AS400 Tutorial AS400 chapters AS400 FAQ. Embedded sql Using EXECUTE IMMEDIATE. Currently, EXECUTE IMMEDIATE USING IN, IN OUT is not supported. You need to workaround to get the similar behavior or you can reach out to EDB support for more assistance.

The syntax for the Oracle EXECUTE IMMEDIATE statement as follows:

When executing a string variable that contains quotes it is important to 'escape' the quote marks.

On 10g and beyond you can 'escape' the quotes with two single quotes or a 'q' and curly brackets:
For example, this 'execute immediate' escapes the quotes with a q'{xxxxxxxx}'
sqlstring := q'{insert into x values( ' i ')}';
execute immediate sqlstring;

As we see, the Oracle EXECUTE IMMEDIATE statement can be used to execute dynamic SQL statements. Oracle EXECUTE IMMEDIATE can also build up statements to execute operations in which you do not know the table names, or other properties.

The Oracle EXECUTE IMMEDIATE statement has a wide variety of uses. For more information on Oracle EXECUTE IMMEDIATE see the following links:

In its most basic form, Oracle EXECUTE IMMEDIATE takes only a single parameter and that is a command string.

Here is an example showing how to use dynamic DDL to create, drop and re-create a table:

EXECUTE IMMEDIATE 'create table abcd (efgh NUMBER)';
EXECUTE IMMEDIATE 'drop table abcd';
EXECUTE IMMEDIATE 'create table abcd (efgh VARCHAR2(10))';

You can use this method to execute any DDL.

More than likely, you will use dynamic SQL to execute DML commands more often than DDL. With dynamic SQL you can issue inserts, updates and deletes just as you can with static SQL:

EXECUTE IMMEDIATE 'INSERT INTO abcd (efgh) VALUES (:text_string)'
USING 'ijkl';
EXECUTE IMMEDIATE 'INSERT INTO abcd (efgh) VALUES (:text_string)'
USING 'mnop';
'SET efgh = :text_string WHERE efgh = :second_string'
USING 'qrst', 'mnop';
'WHERE efgh = :text_string '
USING 'qrst';


As useful as DDL and DML are, a database is not very useful if you can't get your data out. You can also use execute immediate to select your data back out.

v_data abcd.efgh%TYPE;

v_data_row abcd%ROWTYPE;


EXECUTE IMMEDIATE 'SELECT efgh FROM abcd WHERE efgh = :text_string'
INTO v_data
USING 'ijkl';

DBMS_OUTPUT.PUT_LINE( 'Column Variable: ' v_data );

EXECUTE IMMEDIATE 'SELECT * FROM abcd WHERE efgh = :text_string'
INTO v_data_row
USING 'ijkl';

DBMS_OUTPUT.PUT_LINE( 'Row Variable: ' v_data_row.efgh );


INFO: Column Variable: ijkl
INFO: Row Variable: ijkl

Note: There are cases where you can get an insufficient privileges error when executing a stored procedure that contains execute immediate statements.

As400 sql digitsAn SQL INSERT statement adds one or more records to any single table in a relational database. In order to create an RPGLE source member that can use embedded SQL, you must use a source type of SQLRPGLE. To compile an SQLRPGLE source member, use the 'Create SQL ILE RPG Object' (CRTSQLRPGI) command. If you are using PDM, option 14 will create a bound program, and option 15 will create a *MODULE object. If you are issuing the command manually, use the OBJTYPE parameter to indicate *PGM or *MODULE. Also, if your program updates a file that is not journaled, you must change the command option COMMIT to *NONE, otherwise the updates will not occur.
Its better to use the SET OPTION SQL statement.As400 It allows you to enforce certain program options in the code itself rather than on the compile command which you might forget to do.

Sample SQLRPGLE Program to Insert data in db2 on iSeries(AS400)

Host Variables

Host variables are always preceded in SQL by a colon. Since your RPGLE program is the 'host' of these SQL statements, the term host variable refers to any variable declared in the RPGLE program. We can use these variables when we execute SQL as parameters or as return values.

INSERT Statement

Insert statements have the following form:
INSERT INTO table (column1, [column2, .. ]) VALUES (value1, [value2, .. ])

As400 Sql Update Examples

The number of columns and values must be the same. If a column is not specified, the default value for the column is used. Shorthand may also be used, taking advantage of the order of the columns when the table was created. It is not required to specify all columns in the table since any other columns will take their default value or remain null:

As400 Sql Digits

A SQL feature (since SQL-92) is the use of row value constructors to insert multiple rows at a time in a single SQL statement:
INSERT INTO 'TABLE' ('column-a', ['column-b', ..])

As400 Sql Insert Example

('value-2a', ['value-2b', ..]),
