What is the difference between JdbcTemplate and SimpleJdbcTemplate?

SimpleJdbcTemplate – this class combines the most frequently used features of both JdbcTemplate and NamedParameterJdbcTemplate plus it adds additional convenience by taking advantage of some Java 5 features like varargs, autoboxing and generics to provide an easier to use API.

What is the alternative to using JdbcTemplate?

These features combined with those I mentioned earlier make JDBI a compelling alternative to JdbcTemplate. Due to the fact it works nicely in combination with Spring’s transaction system, there’s little effort needed to start using it.

What is the difference between JdbcTemplate and HibernateTemplate?

HibernateTemplate v/s JdbcTemplate Spring provides support for both hibernate and JDBC template classes. It provides template classes which contains all common code. But JDBC as we all know is not an ORM tool it does not represent rows as objects whereas Hibernate does that.

What is the difference between ResultSetExtractor and RowMapper?

A RowMapper is usually a simpler choice for ResultSet processing, mapping one result object per row instead of one result object for the entire ResultSet. ResultSetExtractor is suppose to extract the whole ResultSet (possibly multiple rows), while RowMapper is feeded with row at a time.

How does JdbcTemplate work in spring?

The JdbcTemplate class executes SQL queries, iterates over the ResultSet , and retrieves the called values, updates the instructions and procedure calls, “catches” the exceptions, and translates them into the exceptions defined in the org. springframwork.

What is spring boot JdbcTemplate?

Spring JdbcTemplate is a powerful mechanism to connect to the database and execute SQL queries. It internally uses JDBC api, but eliminates a lot of problems of JDBC API.

How do I inject JdbcTemplate in spring boot?

1. Insert Record In Db With Spring Boot Jdbctemplate.
2. Insert Record In Db With Spring Boot Namedparameter Jdbctemplate.
3. Fetch Auto Generated Primary Key Value After Insert Spring Jdbc.

5. Execute Stored Procedure In Spring Jdbc.

How does JdbcTemplate work in Spring?

How does JdbcTemplate connect to database?

JdbcTemplate requires an object of DataSource to communicate with the database. Since the data source mentioned above is an interface, we must provide an instance of class which implements it….

1. Fetching All records from a table.
2. Fetching a column value for a record.
3. Fetching the count of all records in a table.

Which is better JdbcTemplate or Hibernate?

Hibernate makes a lot of assumptions and forces you to think and code in a certain way. Using JdbcTemplate is easier because it’s just a very thin wrapper around JDBC itself. The price here is that you will write thousands of lines of really boring code. Also, you will find that SQL strings are really hard to maintain.

What is the difference between JDBC and JdbcTemplate?

The Spring JDBC Template has the following advantages compared with standard JDBC. The Spring JDBC template allows to clean-up the resources automatically, e.g. release the database connections. The Spring JDBC template converts the standard JDBC SQLExceptions into RuntimeExceptions.

What is the use of JdbcTemplate in spring?

The Spring JDBC template allows to clean-up the resources automatically, e.g. release the database connections. The Spring JDBC template converts the standard JDBC SQLExceptions into RuntimeExceptions. This allows the programmer to react more flexible to the errors.

Why do we use JdbcTemplate?

JdbcTemplate class is the central class in the JDBC core package. It simplifies the use of JDBC and helps to avoid common errors. It executes core JDBC workflow, leaving the application code to provide SQL and extract results.

Can we use JdbcTemplate in Spring boot?

Spring Boot supports H2 (an in-memory relational database engine) and automatically creates a connection. Because we use spring-jdbc , Spring Boot automatically creates a JdbcTemplate . The @Autowired JdbcTemplate field automatically loads it and makes it available.

Can we use JdbcTemplate without Spring?

You can generally use Spring’s JdbcTemplate without Spring Boot by registering the DataSource, TransactionManager, and JdbcTemplate beans. You can also register the DataSourceInitializer bean to initialize the database. You should configure the JDBC connection parameters in src/main/resources/application.

Can we use JDBCTemplate with Hibernate?

Mostly we are using hibernate for normal operations, if there are big queries or heavy operations, we check performance for jdbc and hibernate whichever better we use it. The good point is HibernateTransactionManager works for both (JdbcTemplate, plain jdbc) and hibernate.
