  • SQL Version Analysis
    Rory McGann SQL Version Analysis Structured Query Language, or SQL, is a powerful tool for interacting with and utilizing databases through the use of relational algebra and calculus, allowing for efficient and effective manipulation and analysis of data within databases. There have been many revisions of SQL, some minor and others major, since its standardization by ANSI in 1986, and in this paper I will discuss several of the changes that led to improved usefulness of the language. In 1970, Dr. E. F. Codd published a paper in the Association of Computer Machinery titled A Relational Model of Data for Large shared Data Banks, which detailed a model for Relational database Management systems (RDBMS) [1]. In order to make use of this model, a language was needed to manage the data stored in these RDBMSs. In the early 1970’s SQL was developed by Donald Chamberlin and Raymond Boyce at IBM, accomplishing this goal. In 1986 SQL was standardized by the American National Standards Institute as SQL-86 and also by The International Organization for Standardization in 1987. The structure of SQL-86 was largely similar to SQL as we know it today with functionality being implemented though Data Manipulation Language (DML), which defines verbs such as select, insert into, update, and delete that are used to query or change the contents of a database. SQL-86 defined two ways to process a DML, direct processing where actual SQL commands are used, and embedded SQL where SQL statements are embedded within programs written in other languages. SQL-86 supported Cobol, Fortran, Pascal and PL/1.

  • SQL/PSM Stored Procedures Basic PSM Form Parameters In
    Stored Procedures PSM, or “persistent, stored modules,” SQL/PSM allows us to store procedures as database schema elements. PSM = a mixture of conventional Procedures Stored in the Database statements (if, while, etc.) and SQL. General-Purpose Programming Lets us do things we cannot do in SQL alone. 1 2 Basic PSM Form Parameters in PSM CREATE PROCEDURE <name> ( Unlike the usual name-type pairs in <parameter list> ) languages like C, PSM uses mode- <optional local declarations> name-type triples, where the mode can be: <body>; IN = procedure uses value, does not Function alternative: change value. CREATE FUNCTION <name> ( OUT = procedure changes, does not use. <parameter list> ) RETURNS <type> INOUT = both. 3 4 1 Example: Stored Procedure The Procedure Let’s write a procedure that takes two CREATE PROCEDURE JoeMenu ( arguments b and p, and adds a tuple IN b CHAR(20), Parameters are both to Sells(bar, beer, price) that has bar = IN p REAL read-only, not changed ’Joe’’s Bar’, beer = b, and price = p. ) Used by Joe to add to his menu more easily. INSERT INTO Sells The body --- VALUES(’Joe’’s Bar’, b, p); a single insertion 5 6 Invoking Procedures Types of PSM statements --- (1) Use SQL/PSM statement CALL, with the RETURN <expression> sets the return name of the desired procedure and value of a function. arguments. Unlike C, etc., RETURN does not terminate Example: function execution. CALL JoeMenu(’Moosedrool’, 5.00); DECLARE <name> <type> used to declare local variables. Functions used in SQL expressions wherever a value of their return type is appropriate.

  • SQL Commands
    Computer Science (083) _ 7th Week Assignment with Notes Chapter Name: - MySQL Revision tour Class: -12th SQL Commands o SQL commands are instructions. It is used to communicate with the database. It is also used to perform specific tasks, functions, and queries of data. o SQL can perform various tasks like create a table, add data to tables, drop the table, modify the table, set permission for users. 1. Data Definition Language (DDL) o DDL changes the structure of the table like creating a table, deleting a table, altering a table, etc. o All the command of DDL are auto-committed that means it permanently save all the changes in the database. Here are some commands that come under DDL: o CREATE o ALTER o DROP o TRUNCATE CREATE :- It is used to create a new table in the database. Syntax: CREATE TABLE TABLE_NAME (COLUMN_NAME DATATYPES[,....]); Example: CREATE TABLE EMPLOYEE(Name VARCHAR2(20), Email VARCHAR2(100), DOB DAT E); DROP: It is used to delete both the structure and record stored in the table. Syntax:- DROP TABLE ; Example:- DROP TABLE EMPLOYEE; ALTER: It is used to alter the structure of the database. This change could be either to modify the characteristics of an existing attribute or probably to add a new attribute. Syntax: To add a new column in the table ALTER TABLE table_name ADD column_name COLUMN-definition; To modify existing column in the table: ALTER TABLE MODIFY(COLUMN DEFINITION....); EXAMPLE ALTER TABLE STU_DETAILS ADD(ADDRESS VARCHAR2(20)); ALTER TABLE STU_DETAILS MODIFY (NAME VARCHAR2(20)); TRUNCATE: It is used to delete all the rows from the table and free the space containing the table.

  • Design Tip #107 Using the SQL MERGE Statement for Slowly Changing Dimension Processing
    www.kimballgroup.com Number 107, November 6, 2008 Design Tip #107 Using the SQL MERGE Statement for Slowly Changing Dimension Processing By Warren Thornthwaite Most ETL tools provide some functionality for handling slowly changing dimensions. Every so often, when the tool isn’t performing as needed, the ETL developer will use the database to identify new and changed rows, and apply the appropriate inserts and updates. I’ve shown examples of this code in the Data Warehouse Lifecycle in Depth class using standard INSERT and UPDATE statements. A few months ago, my friend Stuart Ozer suggested the new MERGE command in SQL Server 2008 might be more efficient, both from a code and an execution perspective. His reference to a blog by Chad Boyd on MSSQLTips.com gave me some pointers on how it works. MERGE is a combination INSERT, UPDATE and DELETE that provides significant control over what happens in each clause. This example handles a simple customer dimension with two attributes: first name and last name. We are going to treat first name as a Type 1 and last name as a Type 2. Remember, Type 1 is where we handle a change in a dimens ion attribute by overwriting the old value with the new value; Type 2 is where we track history by adding a new row that becomes effective when the new value appears. Step 1: Overwrite the Type 1 Changes I tried to get the entire example working in a single MERGE statement, but the function is deterministic and only allows one update statement, so I had to use a separate MERGE for the Type 1 updates.

Queries returning a single tuple can be used Svetlozar Nestorov with INTO. 3. Queries returning several tuples can be Lecture Notes #15 used via a cursor. Cursors Fetching Tuples From a Cursor • A cursor serves as a tuple-variable that • Get next tuple: ranges over the tuples of the result of a FETCH c INTO a1, a2, …, ak; query. – a1, a2, …, ak are the attributes of the result of DECLARE c CURSOR FOR (<query>); the query of c. • Opening a cursor evaluates <query>. – c is moved to the next tuple. OPEN c; • A cursor is used by creating a loop around • Closed with CLOSE c; FETCH. End of Cursor Cursor Structure • SQL operations return status in DECLARE c CURSOR FOR… SQLSTATE (in PSM). … • FETCH returns ‘02000’ in SQLSTATE cursorLoop: LOOP … when no more tuples are found. FETCH c INTO…; • Useful declaration: IF NotFound THEN LEAVE cursorLoop; DECLARE NotFound CONDITION FOR END IF; SQLSTATE ‘02000’ … END LOOP; 1 Cursor Example Example • Write a procedure that makes free all beers BEGIN OPEN c; sold for more than $5 at Spoon. menuLoop: LOOP CREATE PROCEDURE FreeBeer() FETCH c INTO aBeer, aPrice; IF NotFound THEN LEAVE menuLoop END IF; DECLARE aBeer VARCHAR[30]; IF aPrice > 5.00 THEN DECLARE aPrice REAL; UPDATE Sells DECLARE NotFound CONDITION FOR SET price = 0 WHERE bar = ‘Spoon’ and beer = aBeer; SQLSTATE ‘02000’; END IF; DECLARE CURSOR c FOR END LOOP; SELECT beer, price FROM Sells WHERE bar = CLOSE c; ‘Spoon’; END; MySQL Routines Procedures • MySQL’s version of PSM (Persistent, CREATE PROCEDURE <name>(<arglist>) Stored Modules).
