Type  SPRING. Spring Jdbc. Template tutorial. In Spring Jdbc. Template tutorial, we show how to work with data using Springs Jdbc. Template. We use Derby and My. SQL databases. We create a Spring Boot application which uses. Jdbc. Template. Zet. Code has a complete e book for My. SQL Java, which contains. Jdbc. Template chapter My. SQL Java programming e book. Table of contents. Spring is a popular Java application framework. Jdbc. Template is a. JDBC. It takes care of tedious and error prone. Jdbc. Template is included in Springs. Spring Boot is a Springs solution to create stand alone, production grade. Spring based applications. Apache Derby is an open source relational database implemented entirely in Java. It has small footprint and is easy to deploy and install. It supports both embedded. My. SQL is an open source relational database management system. It is one. of the most popular databases. It is often used in web applications. Creating a database in Derby. We create a new testdb database in Derby. It will have a simple. Figure Database creation. In the Net. Beans Services tab, we right click on the Java DB node and select the. Create Database option. We give it a testdb name. Note that the. database is located in the. CREATE TABLE CARSID INTEGER NOT NULL PRIMARY KEY GENERATED ALWAYS AS IDENTITY. START WITH 1, INCREMENT BY 1, NAME VARCHAR3. PRICE INT. INSERT INTO CARSName, Price VALUESAudi, 5. INSERT INTO CARSName, Price VALUESMercedes, 5. INSERT INTO CARSName, Price VALUESSkoda, 9. INSERT INTO CARSName, Price VALUESVolvo, 2. INSERT INTO CARSName, Price VALUESBentley, 3. INSERT INTO CARSName, Price VALUESCitroen, 2. INSERT INTO CARSName, Price VALUESHummer, 4. INSERT INTO CARSName, Price VALUESVolkswagen, 2. This is the SQL to create the Cars table the ID. We can use the Net. Beans tools to. create the Cars table. We right click on the Databases node. Draftsight Autocad 2013: Full Version Software there. New connection option. Figure Connections. A new connection object is created it is represented by an orange icon. Its context menu provides options to connect to the specified database and. The Execute command option shows a tool to execute. SQL commands. In this window, we can use the above SQL to create the Cars. Creating a database in My. SQL. In this section, we create a new testdb database in My. SQL. We use the mysql monitor to do the job, but we could easily. Net. Beans database tool as well. DROP TABLE IF EXISTS Cars. CREATE TABLE CarsId INT PRIMARY KEY AUTOINCREMENT. Name VARCHAR5. 0, Price INTEGER ENGINEInno. DB. INSERT INTO CarsName, Price VALUESAudi, 5. INSERT INTO CarsName, Price VALUESMercedes, 5. INSERT INTO CarsName, Price VALUESSkoda, 9. INSERT INTO CarsName, Price VALUESVolvo, 2. INSERT INTO CarsName, Price VALUESBentley, 3. INSERT INTO CarsName, Price VALUESCitroen, 2. INSERT INTO CarsName, Price VALUESHummer, 4. INSERT INTO CarsName, Price VALUESVolkswagen, 2. This is the SQL to create the Cars table in My. SQL. To create the database and the table, we use the mysql. My. SQL is started with sudo service mysql start command. We connect to the database with the mysql monitor. CREATE DATABASE testdb. Query OK, 1 row affected 0. With the CREATE DATABASE statement, a new database is created. USE testdb. mysql SOURCE carsmysql. With the source command, we load and execute the carsmysql. SELECT FROM Cars. Id Name Price. Audi 5. Mercedes 5. 71. Skoda 9. Volvo 2. 90. 00. Bentley 3. Citroen 2. 10. Hummer 4. Volkswagen 2. 16. We verify the data. Maven dependencies. For our applications, we need to download the database drivers and the. Spring modules. We do it with Maven. Id org. springframeworklt group. Id. lt artifact. Id spring jdbclt artifact. Id. lt version 4. RELEASElt version. This will download the spring jdbc module. Id org. apache. Id. Id derbyclientlt artifact. Id. lt version 1. This is the Maven dependency for the Derby driver. Id mysqllt group. Id. lt artifact. Id mysql connector javalt artifact. Id. lt version 5. This is the Maven dependency for the My. SQL driver. The query. For. Object method. The query. For. Object method executes an SQL query and. The result type is specified in the arguments. Spring. DBQuery. Object. SQLException. import org. Jdbc. Template. import org. Simple. Driver. Data.

System. out. formatThere are d cars in the table, num. Of. Cars. In the example, we use the query. For. Object method to get. Cars table. String sql SELECT Count FROM Cars. This SQL returns the number of rows in the codeinlineCars table. Of. Cars jtm. query. For. Objectsql, Integer. The second parameter of the query. For. Object method specifies. Integer in our case. Row. Mapper. Row. Mapper maps rows of a result set on a per row basis. Implementations of this interface perform the actual. Car. private Long Id. String name. private int price. Long get. Id. Id.
