Class SqlSimpleFactory

java.lang.Object
  org.sqlproc.engine.SqlSimpleFactory

All Implemented Interfaces:

SqlEngineFactory

Direct Known Subclasses:

JdbcEngineFactory

public class SqlSimpleFactory
extends Object
implements SqlEngineFactory

The simple implementation of the SqlEngineFactory.

It's suitable mainly for the Spring DI based configuration, like the next one for the new loader SqlProcessorLoader:

 <beans ...>
   ...
   <bean id="typeFactory" class="org.sqlproc.engine.jdbc.type.JdbcTypeFactory" factory-method="getInstance" />
 
   <bean id="sqlFactory" class="org.sqlproc.engine.SqlSimpleFactory" init-method="init">
     <property name="metaFilesNames">
       <list>
         <value>statements.qry</value>
       </list>
     </property>
     <property name="typeFactory" ref="typeFactory" />
   </bean>
 </beans>
 

or like the next one for the old loader SqlEngineLoader:

 <beans ...>
   ...
   <bean id="typeFactory" class="org.sqlproc.engine.jdbc.type.JdbcTypeFactory" factory-method="getInstance" />
 
   <bean id="sqlQueries" class="org.springframework.beans.factory.config.PropertiesFactoryBean">
     <property name="location">
       <value>classpath:queries.properties</value>
     </property>
   </bean>
   
   <bean id="sqlFactory" class="org.sqlproc.engine.SqlSimpleFactory" init-method="init">
     <property name="metaProps" ref="sqlQueries" />
     <property name="typeFactory" ref="typeFactory" />
   </bean>
 </beans>
 

and use the next code to obtain an instance of the SQL Query engine

 SqlQueryEngine sqlEngine = sqlFactory.getQueryEngine("ALL");
 

or the next code to obtain an instance of the SQL CRUD engine

 SqlCrudEngine sqlEngine = sqlFactory.getCrudEngine("ALL");
 

In the case the SQL Processor runs on the top of the JDBC stack, there's more suitable JdbcEngineFactory.

For more info please see the Tutorials.
