In very early versions of the SQL standard the return code was called SQLCODE and used a different coding schema. The following table lists the standard-conforming values - based on SQL:2011 . [ 1 ] The table's last column shows the part of the standard that defines the row.
SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce after learning about the relational model from Edgar F. Codd [12] in the early 1970s. [13] This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasirelational database management system, System R, which a group at IBM San ...
This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.
IBM also introduced "adaptive compression" capability in DB2 10.1, a new approach to compressing data tables. In June 2013, IBM released DB2 10.5 (code name "Kepler"). On 12 April 2016, IBM announced DB2 LUW 11.1, and in June 2016, it was released. In mid-2017, IBM re-branded its DB2 and dashDB product offerings and amended their names to "Db2".
SQL/DS [1] (Structured Query Language/Data System), [2] released in 1981, was IBM's first commercial relational-database management system. [3] It implemented the SQL database-query language. SQL/DS ran on the DOS/VSE and VM/CMS operating systems. [4] A little later, IBM also introduced Db2, another SQL-based DBMS, this one for the MVS ...

SPUFI (SQL Processor Using File Input) is a database facility invented by IBM for interfacing with their Db2 system. It is accessed from within TSO ISPF from the DB2I Primary Option menu. SPUFI allows direct input of SQL commands in the TSO environment, rather than having them embedded within a program.
The syntax of the SQL programming language is defined and maintained by ISO/IEC SC 32 as part of ISO/IEC 9075.This standard is not freely available. Despite the existence of the standard, SQL code is not completely portable among different database systems without adjustments.
