Oracle pro c manual

Specifying useful precompiler options inline and on the command line and change their values during precompilation.

The use of datatype equivalencing to control the way Oracle interprets input data and formats output data. Conditionally precompiling sections of code in your host program so that it can run in different environments. When you install Oracle software, a directory structure is created on your hard drive for the Oracle products. Table precomp Directory Structure. For example, do not use the following formats:. To use the DLLs, you must link your application with the import libraries.

Microsoft provides you with three libraries: libc. The Oracle DLLs use the msvcrt. You must link the applications with msvcrt. The answers are more informal than the documentation in the rest of this Guide, but do provide references to places where you can find the reference material.

While it has user-callable functions, it is primarily a runtime library for the precompiler suite of languages. For example, I would d like to be able to input the name of a table in my SQL statements at runtime.

But when I use host variables, I get precompiler errors. See "Host Variable Referencing". To solve your problem, you need to use dynamic SQL. There are many options, but we can simplify. Briefly, this means that you must null-terminate the string on input, and it is both blank-padded and null-terminated on output.

In release 8. See "User-Defined Type Equivalencing". On output you must not only allocate the buffer, but pad it out with some non-null characters, then null-terminate it. See "Pointer Variables". It is not an embedded SQL command. Each Oracle installation should have a demo directory. Oracle supports the ANSI standard single equal sign. You must change the logic of some programs to take advantage of the Oracle method. Oracle and Informix Dynamic Server use temporary tables.

The difference being that Oracle creates temporary tables once, and the data is kept separate between sessions. You must manually create temporary tables in Oracle, and separate from the application. The Migration Workbench marks instances of this detected by the converter as errors. For more information on stored procedures refer to the "Triggers, Packages, and Stored Procedures" chapter. Table lists details of possible error messages. The converter failed to understand this statement.

It places it in a comment. You must manually convert it. If it occurs, you must manually add it. The converter has failed on this statement and has continued with the next statement. Release 9. However, some commands do work in ANSI mode. Warning messages are for information purposes and may not require intervention.

Table lists possible warning messages. The generated SQL statements should be similar, but the converter makes no attempt to convert the dynamic SQL statements, however simple commands are converted. For example, you create Oracle temporary tables before running the application.

The data is saved separately each time a session is run. You should close a cursor before reopening it. However, if you specify the Oracle mode default , you do not need to close the cursor. Choosing the oracle mode can increase performance. For further information refer to the "Triggers, Packages, and Stored Procedures" chapter. An informational message. Additional declare cursor facilities not available in Oracle. Oracle databases are seldom dropped in embedded SQL.

If a database is dropped it is ignored. These statements are ignored. This guide provides comprehensive descriptions and examples for using both the command-line interface and the Oracle9i Data Guard Manager graphical user interface.

Support for these tags has been added in the Oracle9 i release 2 9. Programmer's Guide to the Oracle Precompilers. It show you step-by-step how to develop applications that use the powerful database language SQL to access and manipulate Oracle data. Module Language uses parameterized procedures to encapsulate SQL statements.

The procedures can then be called from an Ada application. A number of complete examples using Module Language, Ada code, and stored database procedures are provided. Oracle9i Supplied Java Packages Reference.
