The following example programs demonstrate a number of useful features of
the Firebird programming interface.

Note that the following environment variables need to be set before running
the examples:

ISC_USER - A valid username on the server.
ISC_PASSWORD - The password for the above user.
ISC_DATABASE - The path to the employee.gdb example database, including
server name. For example, to connect to the NT server
named "NTserver" via NetBEUI:
ISC_DATABASE=\\NTserver\c:\firebird\examples

This assumes that Firebird was installed to the
firebird directory on the c: drive.

In addition, a guest account should be created with the username "guest"
and password "guest" before running api15 and winevent.

Embedded Static SQL

Program Description
--------- ------------------------------------------------------------------
stat1.e Illustrates a simple update to an existing table, commit, rollback.

stat2.e Illustrates singleton select.

stat3.e Illustrates a simple cursor -- declare/open/close/fetch.

stat4.e Show 'declare table' and 'create table'.

stat5.e Demonstrate 'update where current of'.

stat6.e Select an array.

stat7.e Illustrate blob cursor for select.

stat8.e Illustrate blob cursor for insert.

stat9.e Execute and select from a stored procedure.

stat10.e Demonstrate 'set database', 'connect' and 'set transaction'.

stat11.e Demonstrate 'set transaction' with various isolation options.

stat12.e Event wait and signaling.
stat12t.e

WHENEVER SQLERROR and BASED_ON clause are illustrated by many programs.



Embedded Dynamic SQL

Program Description
--------- ------------------------------------------------------------------
dyn1.e Execute 'create database' statement as a static string.

dyn2.e 'Execute immediate', and 'prepare' and 'execute'.

dyn3.e Dynamic cursor for select with output SQLDA allocated.

dyn4.e Execute an update query with parameter markers and input SQLDA.

dyn5.e Demonstrate dynamic reallocation of SQLDA and 'describe' statement.

dynfull.e A full_dsql program (process unknown statements).

VARY struct is used by dyn3.e, dynfull.e.



API Interface

Program Description
--------- ------------------------------------------------------------------
api1.c Execute 'create dabatabase' statement as a static string.
Demonstrates zero database handle.

api2.c 'Execute immediate', and 'prepare' and 'execute'.

api3.c Dynamic cursor for select with output SQLDA allocated.

api4.c Execute an update query with parameter markers and input SQLDA.

api5.c Demonstrate dynamic reallocation of SQLDA and 'describe' statement.

apifull.c A full_dsql program (process unknown statements).
Demonstrates stmt_info calls and numeric scale.

api6.c Assemble an update current of statement, based on a dynamic
cursor name. Free a statement handle and re-use it as the cursor.

api7.c Demonstrate blob_open, get_segment.

api8.c Demonstrate create_blob, put_segment.

api9.c Demonstrate blob_open2 (using blob filter).
api9f.c Filter for api9.c.

api10.c Update an array using get_slice/put_slice.

api11.c Execute and select from a stored procedure.

api12.c A program with several active transactions.

api13.c A multi-database transaction with 2-phase commit.

api14.e Combine the three programming styles in one program.

api15.c Construct a database parameter buffer. db_info calls.

api16.c Demonstrate asynchronous event trapping.

winevent.c Demonstrate asynchronous event trapping
(Replacement for api16.c on Windows Client)

api16t.c Identical to stat12t, this triggers the event for api16.

VARY struct is used by api3.c, apifull.c, and api14.e.

SQLCODE extraction from status is covered by several programs.

Zero transaction handle is covered in several programs, ex. api14.e.



Object-oriented API (interfaces)

Program Description
--------- --------------------------------------------------------
01.create.cpp / A sample of creating new database and new table in it.
01.create.pas Has pascal (delphi) implementation.

02.update.cpp UPDATE statement with parameters.

03.select.cpp SELECT statement without input parameters.

04.print_table.cpp Open cursor from attachment and access blob data.

05.user_metadata.cpp Cursor with user-implemented interface of message format.

06.fb_message.cpp Use of static messages and decfloat values.

07.blob.cpp Loading data into blob and reading it.

08.events.cpp Working with events.

09.service.cpp Using services: prints server version and db statistics.

10.backup.cpp Using services: backup database.

11.batch.cpp Working with batch interface.

12.batch_isc.cpp Working with batch interface from ISC API.


FbSampleAtomic typedef required in many examples.



dbcrypt - a sample of XOR database encryption (do not use in production!!!)

extauth - authentication for cross-server connections based on having same secret key on all servers

replication - a sample or replication. Doesn't do anything useful just write log of calls from the engine.
