Using Ant Build Scripts to Drop Mysql Table
This example illustrates how to drop table through the build.xml file
by simply running the ant command. In this build.xml file, we are
using 4 property elements for connectivity of database. The first property <property
name="sql.driver"> is used to connect the sql driver. The
second property <property name="sql.url"> is used to
define the database url and database name. The third property <property
name="sql.user"> is used to define user name of the database.
The fourth property <property name="sql.pass"> is used
to define the password name of the database.
In this build.xml file, <target
name="createTables"> is used to execute the query which is in
the client.sql and project.sql file and <target
name"dropTables"> is used to execute the query which is in the
deleteclient.sql and deleteproject.sql file. In the target <target
name="dropTable">, a condition is used - whether the user
wants to delete the file or not. If the user gives input 'n', then the table
can't be deleted but if the user give input 'y', then the table will be
completely deleted. The source code of the build.xml file is as
follows:
|
<project name="MysqlCreateTable" basedir="." default="dropTables">
<property name="sql.driver" value="org.gjt.mm.mysql.Driver"/>
<property name="sql.url" value="jdbc:mysql://192.168.10.211/test"/>
<property name="sql.user" value="sandeep"/>
<property name="sql.pass" value="sandeep"/>
<target name="createTables" >
<sql driver="${sql.driver}" url="${sql.url}" userid="${sql.user}" password="${sql.pass}" >
<transaction src="client.sql"/>
<transaction src="project.sql"/>
</sql>
</target>
<target name="dropTables" depends="createTables">
<input message="Are you sure to delete the table?" validargs="y,n" addproperty="do.delete" />
<condition property="do.abort">
<equals arg1="n" arg2="${do.delete}"/>
</condition>
<fail if="do.abort">Build aborted by user.</fail>
<sql driver="${sql.driver}" url="${sql.url}" userid="${sql.user}" password="${sql.pass}" >
<transaction src="deleteclient.sql"/>
<transaction src="deleteproject.sql"/>
</sql>
</target>
</project>

client.sql
|
create table client (
client_id int not null
auto_increment primary key,
client_name text not null
);
|
project.sql
|
create table project (
project_id int not null auto_increment primary key,
project_name text not null
);
|
deleteclient.sql
deleteproject.sql
Create the all client.sql, project.sql, deleteclient.sql,
deleteproject.sql files parallel of the build.xml file and simply
run the build.xml file with ant command in the appropriate path on command
prompt. If the program executes successfully, then the following output will be
displayed.
