JDBC allows Java programs to connect to databases in a standard way. It provides cross-vendor connectivity and data access across relational databases. The key classes and interfaces in JDBC establish database connections, send SQL statements, and process query results. To use JDBC, a program first loads the appropriate driver, gets a connection, creates statements to execute queries and updates, processes the results, and closes the connection. This allows Java applications to access databases in a uniform manner independent of the underlying database.

How to Manage Reception Report in Odoo 17Celine George
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.

This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Procedural Language – SQL
An extension to SQL with design features of
programming languages (procedural and
object oriented)
PL/SQL and Java are both supported as
internal host languages within Oracle
products.
Acts as host language for stored
procedures and triggers.
Provides the ability to add middle tier
business logic to client/server
applications.
Provides Portability of code from one
environment to another
Improves performance of multi-query
transactions.
Provides error handling
DECLARE (optional)

A cursor is a temporary work area created in the
system memory when a SQL statement is
executed.
A cursor contains information on a select
statement and the rows of data accessed by it.
This temporary work area is used to store the
data retrieved from the database, and manipulate
this data.
A cursor can hold more than one row, but can
process only one row at a time. The set of rows
the cursor holds is called the active set.
A cursor is a private set of records
An Oracle Cursor = VB recordset = JDBC
ResultSet
Implicit cursors are created for every query
made in Oracle
Explicit cursors can be declared by a
programmer within PL/SQL.
cursorname%ROWCOUNT Rows returned so far
cursorname%FOUND One or more rows retrieved
cursorname%NOTFOUND No rows found
Cursorname%ISOPEN Is the cursor open

Query the database
A Statement object sends your SQL statement
to the database.
You need an active connection to create a
JDBC statement.
Statement has three methods to execute a
SQL statement:
◦ executeQuery() for QUERY statements
◦ executeUpdate() for INSERT, UPDATE, DELETE, or
DDL statements
◦ execute() for either type of statement
Statement stmt = conn.createStatement();
ResultSet rset = stmt.executeQuery(statement);
int count = stmt.executeUpdate(statement);
boolean isquery = stmt.execute(statement);
1. Create an empty statement object.
2. Execute the statement.

JDBC returns the results of a query in a
ResultSet object.
A ResultSet maintains a cursor pointing to its
current row of data.
Use next() to step through the result set row
by row.
getString(), getInt(), and so on assign each
value to a Java variable.
while (rset.next()) { … }
String val = rset.getString(colname);
while (rset.next()) {
String title = rset.getString("TITLE");
String year = rset.getString("YEAR");
… // Process or display the data
}
1. Step through the result set.
2. Use getXXX() to get each column value.
