CCOOBBOOLL -- DDAATTAABBAASSEE IINNTTEERRFFAACCEE http://www.tutorialspoint.com/cobol/cobol_database_interface.htm Copyright © tutorialspoint.com As of now, we have learnt the use of files in COBOL. Now, we will discuss how a COBOL program interacts with DB2. It involves the following terms: Embedded SQL DB2 Application Programming Host Variables SQLCA SQL Queries Cursors Embedded SQL Embedded SQL statements are used in COBOL programs to perform standard SQL operations. Embedded SQL statements are preprocessed by SQL processor before the application program is compiled. COBOL is known as the Host Language. COBOL-DB2 applications are those applications that include both COBOL and DB2. Embedded SQL statements work like normal SQL statements with some minor changes. For example, that output of a query is directed to a predefined set of variables which are referred as Host Variables. An additional INTO clause is placed in the SELECT statement. DB2 Application Programming Following are rules to be followed while coding a COBOL-DB2 program: All the SQL statements must be delimited between EXEC SQL and END-EXEC. SQL statements must be coded in Area B. All the tables that are used in a program must be declared in the Working-Storage Section. This is done by using the INCLUDE statement. All SQL statements other than INCLUDE and DECLARE TABLE must appear in the Procedure Division. Host Variables Host variables are used for receiving data from a table or inserting data in a table. Host variables must be declared for all values that are to be passed between the program and the DB2. They are declared in the Working-Storage Section. -

Ramakrishnan and J. Gehrke 1 Database Management Systems 3ed, R. Ramakrishnan and J. Gehrke 2 SQL in Application Code SQL in Application Code (Contd.) SQL commands can be called from within a host language (e.g., C++ or Java) program. Impedance mismatch: SQL statements can refer to host variables SQL relations are (multi-) sets of records, with (including special variables used to return status). no a priori bound on the number of records. Must include a statement to connect to the right No such data structure exist traditionally in database. procedural programming languages such as Two main integration approaches: C++. (Though now: STL) Embed SQL in the host language (Embedded SQL, SQL supports a mechanism called a cursor to SQLJ) handle this.

Gehrke 4 Embedded SQL Embedded SQL: Variables Approach: Embed SQL in the host language. A preprocessor converts the SQL statements into special API calls. EXEC SQL BEGIN DECLARE SECTION Then a regular compiler is used to compile the char c_sname[20]; code. long c_sid; short c_rating; float c_age; Language constructs: EXEC SQL END DECLARE SECTION Connecting to a database: EXEC SQL CONNECT Declaring variables: Two special “error” variables: EXEC SQL BEGIN (END) DECLARE SECTION SQLCODE (long, is negative if an error has occurred) Statements: SQLSTATE (char[6], predefined codes for common errors) EXEC SQL Statement; Database Management Systems 3ed, R. -
An Array-Oriented Language with Static Rank Polymorphism
An array-oriented language with static rank polymorphism Justin Slepak, Olin Shivers, and Panagiotis Manolios Northeastern University fjrslepak,shivers,[email protected] Abstract. The array-computational model pioneered by Iverson's lan- guages APL and J offers a simple and expressive solution to the \von Neumann bottleneck." It includes a form of rank, or dimensional, poly- morphism, which renders much of a program's control structure im- plicit by lifting base operators to higher-dimensional array structures. We present the first formal semantics for this model, along with the first static type system that captures the full power of the core language. The formal dynamic semantics of our core language, Remora, illuminates several of the murkier corners of the model. This allows us to resolve some of the model's ad hoc elements in more general, regular ways. Among these, we can generalise the model from SIMD to MIMD computations, by extending the semantics to permit functions to be lifted to higher- dimensional arrays in the same way as their arguments. Our static semantics, a dependent type system of carefully restricted power, is capable of describing array computations whose dimensions cannot be determined statically. The type-checking problem is decidable and the type system is accompanied by the usual soundness theorems. Our type system's principal contribution is that it serves to extract the implicit control structure that provides so much of the language's expres- sive power, making this structure explicitly apparent at compile time. 1 The Promise of Rank Polymorphism Behind every interesting programming language is an interesting model of com- putation. -
