You can achieve the Insert query statement in HSQLDB by using the INSERT INTO command. You have to provide the user-defined data following the column field order from the table.
Syntax
Following is the generic syntax to INSERT a query.
INSERT INTO table_name (field1, field2,...fieldN)
VALUES (value1, value2,...valueN );
To insert a string type data into a table, you will have to use double or single quotes to provide string value into the insert query statement.
Example
Let us consider an example that inserts a record into a table named tutorials_tbl with the values id = 100, title = Learn PHP, Author = John Poul, and the submission date is the current date.
Following is the query for the given example.
INSERT INTO tutorials_tbl VALUES (100,'Learn PHP', 'John Poul', NOW());
After execution of the above query, you will receive the following output −
1 row effected
HSQLDB – JDBC Program
Here is the JDBC program to insert the record into the table with the given values, id =100, title = Learn PHP, Author = John Poul, and the submission date is the current date. Take a look at the given program. Save the code into the InserQuery.java file.
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.Statement;
public class InsertQuery {
public static void main(String[] args) {
Connection con = null;
Statement stmt = null;
int result = 0;
try {
Class.forName("org.hsqldb.jdbc.JDBCDriver");
con = DriverManager.getConnection( "jdbc:hsqldb:hsql://localhost/testdb", "SA", "");
stmt = con.createStatement();
result = stmt.executeUpdate("INSERT INTO tutorials_tbl
VALUES (100,'Learn PHP', 'John Poul', NOW())");
con.commit();
}catch (Exception e) {
e.printStackTrace(System.out);
}
System.out.println(result+" rows effected");
System.out.println("Rows inserted successfully");
}
}
You can start the database using the following command.
\>cd C:\hsqldb-2.3.4\hsqldb
hsqldb>java -classpath lib/hsqldb.jar org.hsqldb.server.Server --database.0
file:hsqldb/demodb --dbname.0 testdb
Compile and execute the above program using the following command.
\>javac InsertQuery.java
\>java InsertQuery
After execution of the above command, you will receive the following output −
1 rows effected
Rows inserted successfully
Try to insert the following records into the tutorials_tbl table by using the INSERT INTO command.
