Description

The DBOMultiFlatSelect element represents the DBO optimized for select operations and conversion in CSV rows.

GreenVulcano® ESB configuration

DBOMultiFlatSelect allows you to run more select statements on the database. The result will be a CSV document with the concatenation of these selects.

Must be defined for each select statement and field the FieldFormatter, that allows you to force the formatting of the values ​​extracted from the database.

DBOMultiFlatSelect element is used by DBOBuilder.

The following table shows its 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.DBOMultiFlatSelect
name required DOMultiFlatSelect name
force-mode required (caller or db2xml): Force mode of the DBO, can be used in DBOBuilder whit more heterogeneous DBO.
Mode:
caller - inherit the mode of the caller
db2xml - data extraction mode
jdbc-connection-name required DataSource JNDI name.
Override connection defined in DBOBuilder.
ignore-input optional (true or false): Tells the engine do not use the input data.
output-data optional The default is the value of @name-Output.

For example:

<?xml version="1.0" encoding="UTF-8"?>
<DBOMultiFlatSelect class="it.greenvulcano.gvesb.datahandling.dbo.DBOFlatSelect"
                    name="Partners_FinalReport-select" type="dbo">
      <FieldFormatters id="0">
           <FieldFormatter field-id="1,2,3" terminator-char=","  type="field-formatter"/>
           <FieldFormatter field-id="4" type="field-formatter"/>
      </FieldFormatters>
      <FieldFormatters id= "1">
           <FieldFormatter field-id="1,2,3" terminator-char=","
                           type="field-formatter"/>
           <FieldFormatter date-format="yyyyMMddHHmmssSSS" 
                           field-id="4" type="field-formatter"/>
      </FieldFormatters>
     <statement id="0" type="select">
          SELECT 'Service Code','MSISDN','Timestamp' from dual
     </statement>
     <statement id= "1" type="select">
          SELECT m.CAMPAIGN, c.MSISDN, c.EVENT_TIME, c.EVENT
          FROM CAMA.CDR_EVENT c, CAMA.MESSAGES m, CAMA.PARTNERS p
          where m.ID = c.MSG_ID   and p.ID = m.PARTNER_ID   and p.ID = @{{PARTNER_ID}}
          and c.EVENT_TIME <= to_timestamp('@{{MIN_REPG_TIME}}','YYYY-MM-DD HH24:MI:SS')
          and c.EVENT_TIME >  to_timestamp('@{{MAX_REPG_TIME}}','YYYY-MM-DD HH24:MI:SS')
     </statement>
</DBOFlatSelect>

will generate the output:

Service Code,MSISDN,Timestamp
TEST_1000130000,+10020000000,20111222170000000
TEST_1000130000,+10020000001,20111222170000000
TEST_1000130000,+10020000002,20111222170000000
TEST_1000130000,+10020000003,20111222170000000
TEST_1000130000,+10020000004,20111222170000000
TEST_1000130000,+10020000005,20111222170000000
TEST_1000130000,+10020000006,20111222170000000
