You can convert the image into a byte stream and save it in the database as a BLOB
To save an image URL in a database using PHP, you can create a table with a column to store the URL. When inserting data, you can use SQL queries with PHP to insert the URL into the database. Make sure to properly sanitize and validate the input to prevent SQL injection or other security vulnerabilities.
No. SQL stands for Structured Query Language and that in itself is a language and it is totally different from Java. However, you can use SQL queries inside Java code with the help of JDBC (Java DataBase Connectivity). But the Java compiler cannot understand/compile standalone SQL syntax unless it is used as part of JDBC.
Java Database Connectivity, a Java API that enables Java programs to execute SQL statements. This allows Java programs to interact with any SQL-compliant database.

There are many kinds of statements that are used in Java and they are predominantly used for database connectivity using JDBCEx:PreparedStatement - for normal SQL QueriesCallableStatement - for stored procedures
Oracle SQL Developer software is a free development environment software package. It enables users to develop software applications using Java for Oracle databases.
It depends what Database you are using. I personally use MySQL so will explain how you would do it using MySQL. You would have to create the MySQL database. I would store the image URL rather than the actual image. Then call it using PHP and a MySQL query. For Example: $sql = "SELECT * FROM Images WHERE Img_Name = 'img1'"; $query = mysql_query($sql); $array = mysql_fetch_array(query); then you would call it into HTML like so:
JDBC mean Java Database Connectivity. In java, using JDBC drivers, we can connect to database. Steps to connect to JDBC. 1) Load the driver, using Class.forName(DriverName); 2) Get the connection object, Connection con = Driver.getConnection(loaded driver name); 3) Create a SQL statement, Statement s = con.createStatement(); 4) Create Resultset object using the statement created above, ResultSet rs = s.executeQuery("sql statement"); Iterate the result set to get all the values from the database. Finally don't miss this 5) s.close(); 6) con.close() ;

Use the JDBC functionality to open a connection to SQL Server. You can read up on how here: http://java.sun.com/javase/technologies/database/
SQL is quite unrelated to Java. It isn't exactly a programming language in the traditional sense; but rather a series of commands to get information from (and to) a database. The basics are actually quite simple; certainly simpler than learning Java.
The definition of SQL training is learning how to code in JAVA and PERL, which are two rather important coding languages in computer science and are significant.
