Maintain definition

The maintain engine is used to do operations that don't return data. These operations are valid for updating data in the server. They only return the result of proccess, if operation has been ok or if there has been a problem while doing the operation.

There are several types of maintain operations: insert, update, delete and multiple operations. Also a maintain operation can call a service to do the job (send email, print a report, ...).

You can put as many operations as you want inside a target. I.e. an insert operation followed by two update operations.

Maintain engine
Note: All maintains are defined in the Maintain.xml file at global folder. View project structure for more info. :::

Maintain

This section describes how the operations are made with AWE maintain engine.

XML maintain structure

The simple maintain structure is the next one:

<target name="[target_name]" public="[public]">
<[OPERATION] multiple="[multiple]" audit="[audit_table]">
<table id="[table_name]" schema="[schema_name]"/>
<field id="[field_name]" table="[table_name]" variable="[field_variable_name]" sequence="[sequence_name]"/>
... (more fields)
<where>
<and>
<filter left-field="[Field id]" condition="[Condition]" right-variable="[Variable]"/>
... (more filters)
<filter left-field="[Field id]" condition="[Condition]" right-variable="[Variable]"/>
</and>
</where>
<variable id="[variable_name]" type="[variable_type]" name="[parameter_name]" list="[variable_list]"/>
<variable id="[variable_name]" type="[variable_type]" value="[static_value]" />
<variable id="[variable_name]" type="[variable_type]" session="[session_variable]"/>
... (more variables)

</[OPERATION]>
</target>

Note: [OPERATION] can be any of the following values: insert, delete, update, multiple, commit, send-email, queue, serve or retrieve-data.

Maintain element

For easier development of maintain, not all elements are required.

<variable id="[variable_name]" type="[variable_type]" value="[static_value]" />
<variable id="[variable_name]" type="[variable_type]" session="[session_variable]"/>
... (more variables)
</insert>
</target>

Important: the name of sequence attribute has been exist in AweKey table

INSERT examples

<!-- Insert into AweQue table -->
<target name="QueNew">
<insert audit="HISAweQue">
<table id="AweQue"/>
<field id="IdeAweQue" sequence="JmsKey" variable="IdeAweQue"/>
<field id="Als" variable="Als"/>
<field id="Des" variable="Des"/>
<field id="QueTyp" variable="QueTyp"/>
<field id="Act" variable="Act"/>
<variable id="IdeAweQue" type="INTEGER" name="IdeAweQue" />
<variable id="Als" type="STRING" name="Als" />
<variable id="Des" type="STRING" name="Des" />
<variable id="QueTyp" type="STRING" name="QueTyp" />
<variable id="Act" type="INTEGER" name="Act" value="1"/>
</insert>
<commit/>
<serve service="RelJmsCon"/>
</target>
<!-- Insert with historic data -->
<target name="SitNew">
<insert audit="HISAweSit">
<table id="AweSit"/>
<field id="IdeSit" sequence="SitKey" variable="IdeSit"/>
<field id="Nam" variable="Nam"/>
<field id="Ord" variable="Ord"/>
<field id="Act" variable="Act"/>
<variable id="Nam" type="STRING" name="Nam" />
<variable id="Ord" type="INTEGER" name="Ord" />
<variable id="Act" type="INTEGER" name="Act" />
<variable id="IdeSit" type="INTEGER" name="IdeSit" />
</insert>
</target>

Insert into select

The INSERT INTO SELECT statement is another way to make an insert statement, but retrieving data from a subquery. The structure of an INSERT INTO SELECT statement is the following:

<target name="[target_name]" public="[public]">
<insert query="[query_to_retrieve_data_from]">
<table id="[table_name]"/>
<field id="[field_name]"/>
... (more fields)
</insert>
</target>

Note: The number of fields defined on INSERT INTO SELECT statement and subquery must match.

INSERT INTO SELECT examples

<!-- Insert into select (maintain.xml) -->
<target name="test">
<insert query="testData">
<table id="test"/>
<field id="Nam"/>
<field id="Ord"/>
</insert>
</target>

<!-- Query for data retrieving (queries.xml) -->
<query id="testData" distinct="true">
<table id="AweKey" />
<field id="KeyNam"/>
<field id="Act"/>
</query>

This will generate the next SQL code:

INSERT INTO test (Nam, Ord) SELECT DISTINCT KeyNam, Act FROM AweKey

  • Audit user - User who is doing the operation
  • Audit timestamp - Date and time of the audit operation
  • Audit type - Insert (I), Update (U) or Delete (D) operation

Commit

The tag <commit/> is used into maintain targets to force the data stored in the database. Usually, used between different maintenance operations to ensure that the data are correct before proceeding to the next step.

Retrieve data

Retrieve data target is useful to retrieve some data from a query (SQL, service, enumerated, etc.) and send it to a maintain process.

Retrieve data has the following xml structure:

<target name="[target_name]">
<retrieve-data service="[service_id]" enumerated="[enumerated_id]" queue="[queue_id]">
<table .../>
<field alias="[field_alias]"
<variable id="[variable_name]" type="[variable_type]" name="[parameter_name]" [[list="list"]
[session="session_variable"] [value="static_value"] [property="property_value"]]/>
... (more variables)
</retrieve-data>
</target>

retrieve-data tag works as a query defined on queries.xml. Every retrieved column will be stored as a parameter named as the column field alias.

NOTE: If you are using AWE sequences, you should consider to prioritize this way of retrieving data for inserting it rather to INSERT INTO SELECT statements.

Retrieve data examples

<target name="testRetrieveDataAndInsertAfter">
<retrieve-data>
<table id="Table1"/>
<field id="Field1" alias="name"/>
<field id="Field2" alias="screen"/>
<field id="Field3" alias="user"/>
<field id="Field4" alias="action"/>
</retrieve-data>
<insert multiple="true">
<table id="Table2"/>
<field id="User" variable="User"/>
<field id="Date" variable="Date"/>
<field id="Action" variable="Action"/>
<field id="Name" variable="Nam"/>
<field id="Active" variable="Active"/>
<variable id="User" type="STRING" name="user"/>
<variable id="Date" type="SYSTEM_DATE"/>
<variable id="Action" type="STRING" name="action"/>
<variable id="Name" type="STRING" name="name"/>
<variable id="Active" type="INTEGER" value="1"/>
