DBOUpdate
Description
The DBOUpdate element represents the DBO optimized for update operations.
GreenVulcano® ESB configuration
DBOUpdate allows you to update data into the database.
Each statement is identified by the id.
Actions can be defined in two ways:
- Single execution of a statement
- Complex execution guided by XML
In the first modality any input is ignored and the code executes the first statement configured.
In the second mode, the input XML (or its transformation) must contain the command (row) valid with all parameters (COL) required by the statement.
The following table shows the DBOUpdate attributes:
| Attribute | Type | Description |
|---|---|---|
| type | fixed | This attribute must assume the value dbo |
| class | fixed | This attribute must assume the value it.greenvulcano.gvesb.datahandling.dbo.DBOUpdate |
| name | required | DBOUpdate name |
| transformation | required | Transformation name |
| force-mode | optional | (caller or xml2db) Force mode of the DBO, can be used in DBOBuilder whit more heterogeneous DBOs. Mode: caller - inherit the mode of the caller xml2db - data entry mode |
| jdbc-connection-name | optional | DataSource JNDI name. Override connection defined in DBOBuilder. |
| ignore-input | optional | (true or false) Tells the engine do not use the input data. |
| input-data | optional | The default is the value of @name-Input. Can be set as the @output-data of a preceding DBO to use its output as input. |
| output-data | optional | The default is the value of @name-Output. |
For example:
<?xml version="1.0" encoding="UTF-8"?>
<DBOBuilder class="it.greenvulcano.gvesb.datahandling.dbobuilder.DBOBuilder"
jdbc-connection-name="ds.gv_test" name="PersonInsertFull" type="dbobuilder">
<DHVariables>
<DHVariable name="decimal-separator" value="."/>
<DHVariable name="grouping-separator" value=","/>
<DHVariable name="format" value="#0.00"/>
</DHVariables>
<DBOUpdate class="it.greenvulcano.gvesb.datahandling.dbo.DBOUpdate"
name="CCardPay" transformation="CCardPay" type="dbo">
<statement id="0" type="update">
update CREDIT_CARD set CREDIT= CREDIT - ?
where CNUMBER=?
and ENABLED=‘Y’
and CREDIT >= ?
</statement>
</DBOUpdate>
</DBOBuilder>
According with the data present into the database, this statement will return the following XML:
<RowSet>
<data>
<row>
<col type="float">10</col>
<col>1111222233334444</col>
<col type="float">10</col>
</row>
</data>
</RowSet>
