(1) Create embedded statements. Embedding SQL into C language for mixed programming will contain statements from two different computational models in the program. In order to distinguish between SQL statements and C statements, it is necessary to prefix all SQL statements with EXEC SQL and end with a semicolon, usually in the form of “EXEC SQL”. Embedded statements are divided into executable statements and declarative statements. Executable statements are used to complete data definition, data manipulation, and data control tasks in interactive SQL statements, while declarative statements are used to declare communication areas and SQL variables.
(2) SQL communication area. The SQL Server database management system provides a communication area called SQLCA, which is used to store the status feedback from the DBMS to the application program during the execution of SQL statements. This information mainly describes the current working status and running environment of the system. The application retrieves this state information from SQLCA to determine the next statement to execute. The statement defined as SQL communication area in C language is: EXEC SQL INCLUDE SQLCA.
(3) Main variable. Embedded SQL statements can use C language program variables and main variables to input or output data. A main variable can be accompanied by an optional indicator variable to indicate whether the value returned to the main variable is a null value and whether the string returned to the main variable has been truncated. When the input main variable appears in an SQL statement, a colon (:) can be added before it to distinguish the table field names. The method of defining output variables as indicator variables is explained between the SQL statements EXEC SQL BEGIN DECLARE Section and EXEC SQL END DECLARE Section.
(4) Link the database. The main function of the C program should include a login statement that provides a username and password to the precompiled and program to establish a link with the SQL Server database management system. The command syntax is: EXEC SQL CONNECT TO server name, database name, AS link name, USER username, password.

Firstly, MI/O has the advantages of PC/104, 3-inch, and 5-inch boards, and has been optimized, such as:
Having a complete interface, it can work independently as a complete single board;
Capable of compact stacked expansion
Simpler heat dissipation design
Similar to traditional PC/104, 3-inch boards, Advantech offers a variety of expansion cards based on the MI/O expansion bus, including commonly used expansion cards such as MI/O network cards and serial cards. Customers can also design their own expansion cards based on the rich interfaces provided by MI/O.
Embedded single board computer with flexible expansion port MI/O

Support the expansion of multiple buses and signals, including high-speed signals (PCIe, dDP, etc.) and low-speed signals (LPC, SM BUS, etc.);
The customer’s own core design part can also be integrated on the expansion board through the MI/O expansion bus;
The extension method of MI/O can simplify the design of the motherboard and significantly reduce the expansion threshold of the motherboard;
In addition, the components of the MI/O motherboard can make the overall embedded system more economical;
Advantech provides MI/O bottom plate design assistance services, which can assist customers in quickly launching their products.
