In SQL procedures, a cursor makes it possible to define a result set (a set of data rows) and perform complex logic on a row by row basis. By using the same mechanics, a SQL procedure can also define a result set and return it directly to the caller of the SQL procedure or to a client application.
Transact-SQL (T-SQL) is Microsoft's and Sybase's proprietary extension to the SQL (Structured Query Language) used to interact with relational databases.T-SQL expands on the SQL standard to include procedural programming, local variables, various support functions for string processing, date processing, mathematics, etc. and changes to the DELETE and UPDATE statements.
In particular, it is a component of Structured Query Language (SQL). Data Control Language is one of the logical group in SQL Commands.

In SQL operations work on a set of records, in the ABL, the operation is applied to a record at a time - much like using a cursor in SQL. Record-based processing provides a clean and reliable locking mechanism which allows the developer to EXECUTIVE-LOCK, SHARE-LOCK or NO-LOCK a record when accessed by the application.
Cursor-for loops automatically open a cursor, read in their data and close the cursor again. As an alternative, the PL/SQL programmer can pre-define the cursor's SELECT-statement in advance to (for example) allow re-use or make the code more understandable (especially useful in the case of long or complex queries).
