Make sure to read the license however: We grant you a nonexclusive, nontransferable limited license to use the programs only for the purpose of developing, testing, prototyping and demonstrating your application, and not for any other purpose.
If you use the application you develop under this license for any internal data processing or for any commercial or production purposes, or you want to use the programs for any purpose other than as permitted under this agreement, you must obtain a production release version of the program by contacting us or an Oracle reseller to obtain the appropriate license.
You acknowledge that we may not produce a production release version of the program and any development efforts undertaken by you are at your own risk.
We may audit your use of the programs. If you want to use the sample programs, you will have to restart Oracle Universal Installer and perform a custom installation. The place you are looking for is in the development tools section. Once you get to the Available Product Components section, select Oracle Programmer the option may show Reinstall; the screen shot shows Installed because I have already reinstalled this component.
Continue with the installation it takes a few minutes and then exit the installer. You should see quite a few folders similar to those shown below. The getting started for Windows guide includes a description of each demo program.
Some of the demos require additional scripts to be run, so check Table as needed. They are there, kind of sort of. After running the precompiler, a. Once the. Configuration is actually a two-part process. Project files have an extension of. To open an existing project, choose Open Project from the File menu. Step 2: Set the Default Output File Name optional Use the Preferences menu to choose the manner in which a name is assigned to the output files.
This setting only affects input files that you add later. An existing output file name will not change. However, you can change an existing output file name by double-clicking the output file and entering a new name.
Enter an output file name for the file selected. Once you select or enter a file name, it appears in the Output File area of the information pane. To change the name of an existing input or output file:.
The Input File or Output File dialog box appears. Click Open. The selected file appears in the information pane. Choose Delete from the Edit menu. Click Yes. Step 5: Set the Precompile Options optional Many useful options are available.
They enable you to control how resources are used, how errors are reported, how input and output are formatted, and how cursors are managed. Choose Options from the Edit menu. The Options dialog box appears. The settings include the type of error information generated and the name of the list file. In addition, click the Help button in the Options dialog box for a condensed version of the information in Chapter 9. Step 6: Specify Database Connection Information optional If you selected semantics or full for the SQL Check option in the Options dialog box, you may need to specify database connection information to the Oracle database.
The name of the system configuration file is pcscfg. The location of the file is system specific. See "Using the Precompiler Options" on page Note: You cannot nest configuration files. The generated code contains data structures that indicate the datatype, length, and address of host variables, as well as other information required by the Oracle runtime library, SQLLIB.
The precompiler can issue warnings and error messages. Table is a quick reference to the major precompiler options. It summarizes the section "Using the Precompiler Options" on page The options that are accepted, but do not have any affect, are not included in this table.
A precompilation unit is a file containing C code and one or more embedded SQL statements. The options specified for a given precompilation unit affect only that unit; they have no effect on other units. You can enter any precompiler option in the command line.
For example, you might enter the following:. Appendix C, "Performance Tuning" shows you how to optimize runtime performance using inline options. Specifying options inline or in a configuration file is also helpful if your operating system limits the number of characters you can enter on the command line. This section is organized for easy reference. It lists the precompiler options alphabetically, and for each option gives its purpose, syntax, and default value.
Usage notes that help you understand how the option works are also provided. Specifies the default mapping of C host variables of type char or char[n], and pointers to them, into SQL. A function prototype declares a function and the datatypes of its arguments. The precompiler generates function prototypes for SQL library routines, so that your C compiler can resolve external references. The CODE option lets you control the prototyping.
An example follows:. The precompiler can also generate other ANSI-approved constructs such as the const type qualifier.
Most C compilers expect a default extension of ". The value of this option is a string, without the quotes or the period. Specifies whether Oracle follows the semantic and syntactic rules of Oracle8, Oracle7, or the native version of Oracle that is, the version to which the application is connected.
In addition, you must also include the SQLCA using one of the following entries in your source code:. Can be entered on the command line or inline. For example, the following use of define is not valid:. Objects in the cache are implicitly unpinned at the end of the duration. Specifies whether error messages are sent to the terminal as well as the listing file YES , or just to the listing file NO.
Specifies an output file in which errors generated in processing type files are written. If omitted, errors are output to the screen. Only one error file will be produced. If multiple values are entered, the last one is used by the precompiler. For more information, see Appendix C. When a SQL data manipulation statement is executed, its associated cursor is linked to an entry in the cursor cache. The cursor cache entry is in turn linked to an Oracle private SQL area, which stores information needed to process the statement.
The link is reused as soon as the cursor cache entry to which it points is needed for another SQL statement. This frees memory allocated to the private SQL area and releases parse locks. This is useful for SQL statements that are executed often because it speeds up subsequent executions. There is no need to reparse the statement or allocate memory for an Oracle private SQL area. For information showing how these two options interact, see Table You can omit the filename extension if it is.
