  • Support Aggregate Analytic Window Function Over Large Data by Spilling
    Support Aggregate Analytic Window Function over Large Data by Spilling Xing Shi and Chao Wang Guangdong University of Technology, Guangzhou, Guangdong 510006, China North China University of Technology, Beijing 100144, China Abstract. ​Analytic function, also called window function, is to query the aggregation of data over a sliding window. For example, a simple query over the online stock platform is to return the average price of a stock of the last three days. These functions are commonly used features in SQL databases. They are supported in most of the commercial databases. With the increasing usage of cloud data infra and machine learning technology, the frequency of queries with analytic window functions rises. Some analytic functions only require const space in memory to store the state, such as SUM, AVG, while others require linear space, such as MIN, MAX. When the window is extremely large, the memory space to store the state may be too large. In this case, we need to spill the state to disk, which is a heavy operation. In this paper, we proposed an algorithm to manipulate the state data in the disk to reduce the disk I/O to make spill available and efficiency. We analyze the complexity of the algorithm with different data distribution. 1. Introducion In this paper, we develop novel spill techniques for analytic window function in SQL databases. And discuss different various types of aggregate queries, e.g., COUNT, AVG, SUM, MAX, MIN, etc., over a relational table. Aggregate ​analytic function, also called aggregate window function, is to query the aggregation of data over a sliding window.

  • 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.
