Please select the driver typeyou need based on the type of your application – Unicode or ANSI.Server-side prepared statements are enabled by default. It is suitablefor use with any MySQL version from 5.5.This is the fourth release of the MySQL ODBC driver conforming to theODBC 3.8 specification. It contains implementations of key 3.8 features,including self-identification as a ODBC 3.8 driver, streaming of outputparameters (supported for binary types only), and support of theSQL_ATTR_RESET_CONNECTION connection attribute (for the Unicode driveronly).Also, Connector/ODBC 5.3 introduces a GTK+-based setup libraryproviding a GUI DSN setup dialog on some Unix-based systems, currentlyincluded in the Debian 7/8/9, EL6/OL6, EL7/OL7 (64-bit only), Fedora 24/25/26,FreeBSD 10/11, SLES 12, Ubuntu 14/16/17 packages. Other newfeatures in the 5.3 driver are FileDSN and Bookmarks support.The release is now available in source and binary form for a number ofplatforms from our download pages at information on installing, please see the documentation at in MySQL Connector/ODBC 5.3.9 (2017-07-24, GeneralAvailability)Functionality Added or ChangedWhen compiling Connector/ODBC on Windows platforms, it can now be linked statically (equivalent to the /MT compiler option in Visual Studio) or dynamically (equivalent to the /MD compiler option in Visual Studio) to the Visual C++ runtime. The default option is to link dynamically; if you want to link statically. set the new CMake option, STATIC_MSVCRT, to true. Another new CMake option, WITH_NODEFAULTLIB, has been introduced for specifying the Visual C++ runtime you want to link Connector/ODBC to when using mixed link types (that is, when link type to the Visual C++ runtime differs for Connector/ODBC and the MySQL client library it links to).

IntroductionIn a world that is rapidly embracing digital transformation, programming languages and their tools have experienced a phenomenal evolution. Central to this transformation is the rise of the online JavaScript compiler. But why has the compiler become such a game-changer in web development?Online JavaScript Compiler: What's the Buzz All About?Kicking off your journey with JavaScript requires a grasp of interpreters and compilers.An interpreter processes code step by step. This interpreter is often embedded in web browsers for JavaScript, letting them directly process and run JavaScript code.When someone accesses a webpage with JavaScript elements, the browser's interpreter processes the code instantly, delivering a lively and engaging experience to the visitor.Conversely, a compiler takes the entire block of code and converts it into machine-readable instructions, leading to immediate execution by the computer.In JavaScript's context, compilers can turn the code into a low-level language, ensuring it runs more swiftly and optimizes performance.It's noteworthy that JavaScript can operate in both interpreted and compiled modes, depending on its deployment and use case.Scaler Topics offers a user-friendly compiler that effortlessly allows you to compile, test, and execute JavaScript tasks online at no cost.Let's see what's in it for you:Writing Code Anywhere, Anytime with JavaScript Online CompilerThe concept of "office" is evolving. Developers, whether they're in a café, at home, or in transit, now need tools that match their dynamic lifestyle. Enter the JavaScript online compiler: a tool that eradicates the need for heavy-duty IDE installations, letting developers write, edit, and execute code straight from their browsers.Instant Compilation and ExecutionImagine having a tool where the gap between writing code and seeing its output is almost non-existent. That's the power of an compiler. It’s about speed, efficiency, and that much-needed momentum, especially during those long coding hours.Dive Deep into Libraries with Rich SupportIt's a myth that online tools limit functionality. On the contrary, most compilers are robust, offering extensive library support. So, whether it’s a popular framework or a niche library, there's a good chance your online compiler supports it.Learning Made Easy and EfficientBeginners, rejoice! Instant feedback mechanisms in JavaScript online compilers mean that every line of code becomes a learning opportunity. This interactive way of learning ensures you grasp concepts faster and more efficiently.Mastering the Interface: Your Comprehensive Guide to Using the Online JavaScript CompilerAccess the Platform: Simply navigate to the website or application and select online JavaScript compiler, since they don't need any kind of installation.Write.

This section describes C API data structures other than those used for prepared statements, the asynchronous interface, or the replication stream interface. For information about those, see Section 6.2, “C API Prepared Statement Data Structures”, Section 7.2, “C API Asynchronous Interface Data Structures”, and Section 10.2, “C API Binary Log Data Structures”. MYSQL This structure represents the handler for one database connection. It is used for almost all MySQL functions. Do not try to make a copy of a MYSQL structure. There is no guarantee that such a copy will be usable. MYSQL_RES This structure represents the result of a query that returns rows (SELECT, SHOW, DESCRIBE, EXPLAIN). The information returned from a query is called the result set in the remainder of this section. MYSQL_ROW This is a type-safe representation of one row of data. It is currently implemented as an array of counted byte strings. (You cannot treat these as null-terminated strings if field values may contain binary data, because such values may contain null bytes internally.) Rows are obtained by calling mysql_fetch_row(). MYSQL_FIELD This structure contains metadata: information about a field, such as the field's name, type, and size. Its members are described in more detail later in this section. You may obtain the MYSQL_FIELD structures for each field by calling mysql_fetch_field() repeatedly. Field values are not part of this structure; they are contained in a MYSQL_ROW structure. MYSQL_FIELD_OFFSET This is a type-safe representation of an offset into a MySQL field list. (Used by mysql_field_seek().) Offsets are field numbers within a row, beginning at zero. my_ulonglong A type used for 64-bit unsigned integers. The my_ulonglong type was used before MySQL 8.0.18. As of MySQL 8.0.18, use the uint64_t C type instead. my_bool A boolean type, for values that are true (nonzero) or false (zero). The my_bool type was used before MySQL 8.0. As of MySQL 8.0, use the bool or int C type instead. Note The change from my_bool to bool means that the mysql.h header file requires a C++ or C99 compiler to compile. The MYSQL_FIELD structure contains the members described in the following list. The definitions apply primarily for columns of result sets such as those produced by SELECT statements. MYSQL_FIELD structures are also used to provide metadata for OUT and INOUT parameters returned from stored procedures executed using prepared CALL statements. For such parameters, some of the structure members have a meaning different from the meaning for column values. Tip To view the MYSQL_FIELD member values for result sets interactively, start the mysql client with the --column-type-info option, then execute some sample queries. char * name The name of the field, as a null-terminated string. If the field was given an alias with an AS clause, the value of name is the alias. For a procedure parameter, the parameter name. char * org_name The name of the field, as a null-terminated string. Aliases are ignored. For expressions, the value is an empty string. For a procedure parameter, the parameter name. char * table The
