#Mysql jdbc connection driver

To interact with the database, it is necessary to do the following.ĭownload the Connector/J 5.1.42 driver available from this link. Installing the Connector/J 5.1.42 Driver for DB Interaction

#Mysql jdbc connection install

Install and choose the right properties for JMeter and the Java Development Kit.Make sure the database is available for remote or local access.Make sure there is a user who has permission to connect and perform common actions CRUD in the database.In this blog post, we will use JMeter 3.2, the database MySQL 5.7.18 Community Edition (which is free and can be installed on your PC) and Java 8.īefore you start working with a database using JMeter, you need to do the following: Based on these examples, each tester can then perform the appropriate interaction with the database, during their further testing.

This article will show you how to check, update, and add entries to your database by using Apache JMeter. The purpose of this interaction is to check the correct record of specific data in the database or to prepare test data for the tests by adding specific records to the database. When testing your APIs, web service, or other system parts, you might need to record or retrieve data from a database. The user only needs to call ODBC API, from ODBC The driver converts the call into a call request to a specific database. Īdd ：ODBC( Open Database Connectivity, open data base connectivity ), It's Microsoft. A collection of different implementations, It is the driver of different databases. ĭifferent database vendors, We need to focus on this set of interfaces, Provide different implementations. JDBC yes sun The company provides a set of interfaces for database operation ,java Programmers only need to program for this set of interfaces.

#Mysql jdbc connection drivers

JDBC Interface （API） There are two levels ：ġ、 Application oriented API：Java API, Abstract interface, For application developers （ Connect to database, perform SQL sentence, Get the results ）.Ģ、 Database oriented API：Java Driver API, For developers to develop database drivers with.

#Mysql jdbc connection code

Different types of databases have corresponding implementations, The code in this article is all about MySQL Database implementation. It's used by a group Java Language Write the class and interface composition. Ĥ）JDBC（ Java Data Base Connectivity） yes Java And a bridge between databases, It's a specification, not an implementation, Be able to execute SQL sentence.

ģ）JDBC The goal is to make Java Programmers use JDBC You can connect to any Provides JDBC The driver Database system of, In this way, programmers don't need to know too much about the characteristics of a specific database system, This greatly simplifies and speeds up the development process. Ģ）JDBC Provides a way to access different databases A unified approach, Some details are blocked for developers. JDBC yes java The cornerstone of access to the database ,JDO、Hibernate、MyBatis It's just a better package JDBC.ġ）JDBC(Java Database Connectivity) It's a Independent of a specific database management system 、 General purpose SQL A common interface for database access and operation （ A group of API）, Defines the criteria for accessing databases Java Class library ,（ java.sql,javax.sql） These libraries can be used in a standard Methods 、 Easy access to database resources. The third party O/R Tools, Such as Hibernate, Mybatis etc. Stay Java in, Database access technology can be divided into the following categories ： （2） The main application of persistence is to store the data in memory in relational database, Of course, it can also be stored in disk files 、XML In the data file. Most of the time, Especially for enterprise applications, Data persistence means saving data from memory to hard disk On top of that ” curing ”, The implementation process of persistence is mostly accomplished through various relational databases. （1） Persistence (persistence)： Save data to a power down storage device for later use. In the bag 3 Each interface defines different ways to call the database ：Ģ、 Use Statement Disadvantages of operating data tablesģ、Java And SQL Corresponding data type conversion tableĥ、 Use PreparedStatement Implement query operation and 、 Operate and access the databaseġ、 stay java.sql There is.
