About Oracle Precompiler Demos

Oracle Precompiler Demos show application programmers how to embed SQL operations in C/C++ and COBOL code in a way that is compatible with ANSI standard.

A Pro*C program is a C program containing embedded SQL statements. Oracle Pro*C/C++ and Pro*COBOL Demos offer extensions to support dynamic SQL operations, which are operations that can change in real time. It is also possible to use dynamic SQL operations through PL/SQL code (known as anonymous PL/SQL block) with a Pro*C/C++ and Pro*COBOL application. Typical applications contain much more static SQL than dynamic SQL. The precompiler translates each embedded SQL statement into calls to the Precompiler run-time library (SQLLIB).

About Oracle Spatial and Graph Demos

Oracle Spatial and Graph Demos provide SQL schema and functions that facilitate the storage, retrieval, update, and query of collections of spatial features in an Oracle AI Database.

Oracle Spatial and Graph is an integrated set of functions and procedures that enables spatial data to be stored, accessed, and analyzed quickly and efficiently in an Oracle AI Database. Spatial data represents the essential location characteristics of real or conceptual objects as those objects relate to the real or conceptual space in which they exist.

About Oracle Internet Directory Client Demos

Oracle Internet Directory Client Demos show application programmers how to use LDAP C and PL/SQL APIs.

All LDAP operations based on the C API, require clients to establish an LDAP session with the LDAP server. For LDAP operations based on the PL/SQL API, a database session must first initialize and open an LDAP session. The DBMS_LDAP package enables PL/SQL applications to access data located in LDAP servers. The names and syntax of the function calls are similar to those of the C API.

About Oracle Call Interface Demos

Oracle Call Interface (OCI) demos include sample C programs to use the OCI APIs.

These programs provide examples of the data types, calling conventions, syntax, and semantics of C.

Related Topics

About Oracle C++ Call Interface Demos

Oracle C++ Call Interface (OCCI) demos provide database access APIs for applications written in C++. The control classes enable the applications to connect to the database and create resources like statements and resultsets. The data classes contain various types of data. The object classes and methods provide a navigational interface to access and manipulate objects. The Object Type Translator (OTT) can be used to generate the C++ class headers for the data types defined in Oracle AI Database. The installed demos illustrate the use of classes and methods for OTT and OCCI.

Preinstallation Considerations

The requirements for installing Oracle AI Database Examples are as follows:

Free Disk Space

Verify that the file system that contains the Oracle home directory has at least:

  • 800 MB of free disk space on UNIX systems.

  • 5.43 GB of free disk space on Windows systems.

The following topics contain details about determining free disk space on UNIX and Windows platforms:

Determining Free Disk Space on UNIX Platforms

Explains how to check free disk space on UNIX platforms.

Use the following command to check that the Oracle home directory has enough space:
  • df —k oracle_home_path
where oracle_home_path is the path to the Oracle home directory.

Determining Free Disk Space on Windows Systems

Explains how to determine free disk space on Windows systems.

Perform the following steps to check that the Oracle home directory has enough space:
  1. Double-click My Computer.
  2. Right-click the drive where the Oracle software is to be installed.
  3. Select Properties.

Required Products

Explains the products that are required to use Oracle AI Database Examples.

Before you can use the Oracle AI Database Examples, you must install the sample schemas in an Oracle AI Database. When you install Oracle AI Database, or use Database Configuration Assistant to create a database, you can choose to include the sample schemas. You can also manually install the sample schemas in an existing database.

Note:

Starting with Oracle Database 21c, all sample schemas are distributed on GitHub:

Identifying the Oracle Home Directory

Explains how to identify the Oracle home directory used by the Oracle AI Database installation.

Before you extract products from Oracle AI Database Examples, you must ensure that your system has access to an Oracle AI Database 26ai Oracle home. If required, you must first install or upgrade to this release of Oracle AI Database.

Identify the Oracle home directory used by the Oracle AI Database installation.

On UNIX platforms, the oratab file is located in the /etc directory or in the /var/opt/oracle directory. Use the more command to check the contents of the oratab file. For example: 

# more /etc/oratab

On Windows platforms:

  1. From the Start menu, choose Programs, then Oracle - HOME_NAME, then Oracle Installation Products, then Universal Installer.
  2. When the Welcome screen appears, click Installed Products.
    The Inventory screen appears, listing all of the Oracle homes on the system and the products installed in each Oracle home.
  3. On the Inventory screen, expand each Oracle home and locate Oracle AI Database 26ai.
  4. Click Close and then Cancel to exit Oracle Universal Installer.
