CL_SQL_STATEMENT - Execution of SQL Statements
The CL_SQL_STATEMENT class contains
instance methods that receive and execute dynamically created SQL
statements.
Instances of the CL_SQL_STATEMENT class can be created using the
statement CREATE OBJECT or the instance
operator NEW , which allow
a reference to an object of the
CL_SQL_CONNECTION class to be passed to the constructor. If no
database connection is passed, a standard connection from the database
interface to the central database of the AS ABAP is used.
DDL and DML Statements
Queries
Stored Procedures
Notes
The CL_SQL_STATEMENT class allows the statement passed to be
executed once. To execute a statement multiple times with different
parameters, you can use the subclass
CL_SQL_PREPARED_STATEMENT .
An object of the class CL_SQL_STATEMENT is often only intended to
be used once, which means it is also only addressed once. In this case,
the instance operator NEW
with appended method call can be used to create the instance. This
removes the need to declare a reference variable explicitly.
The methods in the class CL_SQL_STATEMENT should not be used to
execute transaction-control statements ( COMMIT , ROLLBACK ).
This is because they are not not detected by the database interface,
which then might not execute the actions required at the end of a
transaction. Only the appropriate methods
in the class CL_SQL_CONNECTION can
be used for transaction control.
