That appears to be a list of the new features in the minor release, V2R6.2. A list of all the major enhancements since V2R5.x would include queue tables, stored procedures, table functions, user-defined data types, and recursive queries, along with many others.
Hi All, I am posting a very detailed answer for Teradata Version differences.you can refer it.
TERADATA VERSION DIFFERENCES V2R5 New Features and Eliminated Features 1. Added Identity column features to implement Primary key and Unique key concepts. 2. Statistics can be collected on a. Multiple Non Indexed columns of a table. b. Using sampling data from a table. 3.Partition Primary Indexed Added and types described. 3. Materialized View concept provided through a. Partialy covered join Index. b. Sparse Join Index. 4. Stored procedure features like a. Implementing Cursors using declare cursor statements. b. Altering a Procedure Using Nested computed statements. c. FETCH to get the rows one by one sequentially. d. Get help information on Stored Procedure and Attributes etc. 5. Multi Column Compression for Table Columns. 6. Setting the default DATEFORM form Options. 7. Implementing Multiple Distinct Aggregations in a Select Query etc. V2R5.1 Features 1. ANSI Triggers Introduced. 2.Row Triggers, statement triggers are supported. 3. It allows Recursion and Aggregation inside Triggers. 4. Stored Procedure Enhancement achieved Implemented different recompilation methods of a stored procedure. 5. Recognised requirements for running C compilers in the Teradata UNIX Environment. 6. Provided more Contextual Information for Internal Error 5547. 7. Large Objects supported. a. we can load and unload large objects even in BTEQ(BLOB,CLOB) By Using LargeDatamode. 8. User Defined Functions Added. Note: 1. we cannot write Print Statement inside Procedure. 2. Stored Procedures Created in V2R5.1 require Recompilation. V2R6 FEATURES 1. Queue Tables are added. 2. Triggered Stored Procedure added. 3. Stored Procedure Grammar Merge added. 4. Multi statements request submitted (supported in stored procedures by using BEGIN REQUEST ------ END RESQUEST. 5. External Stored Procedures (xSP added). 6. BLOB’s are supported by stored procedure and External stored procedure. V2R6.1 FEATURES 1. Stored Procedure OUT Parameter Changes. 2. PPI on Volatile and Global temporary tables. 3. User Defined types Added (UTDs) 4. PPI on Join Index added.
V2R6.2 FEATURES 1. Alter Table column Compression added. 2.'CREATE TABLE AS WITH STATISTICS ' ADDED. 3. Auto generated key Retrieval added. TD 12 FEATURES 1. Stored Procedure Enhancements a. Retrieval of one or more results set from a stored procedure. 2. Error Tables Added with external syntax. 3. TERADATA 12 Provides complex error handling capabilities in conjunction with a MERGE INTO (or) INSERT SELECT statements accomplished through the Usage of new SQL based error tables. 4. Usage of ANSI Merge Operation at the time of loading added. 5. Compare and contrast the advantage of Merge instead of MULTILOAD. 6. TD 12 MERGE plan is different from V2R5 MERGE plan. 7. Multilevel Partitioning provided. 8. Added many changes to the User defined functions and Table functions. 9. Supports SQL Invocation Using External Stored Procedures. 10. Teradata Extended Support for Windows Aggregate Function. example STDDEV_SAMP[standard deviation sample] CORR ---Corelation COVAR_SAMP (Corelation Variable sample ) VAR_SAMP etc. 11. It supports DSW of 20 bits also. 12. BLOB and CLOB Extended till 10 GB.
