Mass Extract Utility

Mass extract (massextract) is an OOB utility which can be used to extract data from any tables in WCS, this utility is extremely useful if you need to feed in data from WCS to another system.


Step 1

you have to write a filter definition file, this file will have the SQL query required to extract the data from WCS.
following is one sample filter file if you need to extract data from catentry and catendesc table (The tables which hold the item data and item description tables in WCS)
Refer to following link for more details on Extraction filter format

<sqlx>

    <!-- **************************** -->
    <!-- extract Category information -->
    <!-- **************************** -->

<functionDef id="Product" description="Extract Product"
schemaentity="catentry">
       <body>
        select * from catentry
      </body>
 </functionDef>

    <execute id="Product" description="Extract Product"
schemaentity="catentry">
      </execute>
   
</sqlx>

NOTE: In the extraction filter xml only one schemaentity is allowed for a single sql query, you can not write a query with complex joins as the tool would not know how to map it to the output xml.

Step2

Run the mass extract command from command prompt.
E.g.
C:\IBM\WCDE_ENT70\bin\massextract.bat -filter catentry_filter.xml -outfile catentry.xml -dbname wcs07 -dbuser wcs7 -dbpwd wcs7

This should generate catentry.xml output file consisting of records from catentry file.
E.g. extracted record

<catentry
    catentry_id="10001"
    member_id="7000000000000000051"
    catenttype_id="ProductBean"
    partnumber="Dummy Product"
    mfpartnumber="DummyProduct"
    mfname="Hari"
    markfordelete="0"
    lastupdate="2010-01-08 22:27:15.859"
    onspecial="0"
    buyable="1"
    baseitem_id="10001"
    optcounter="1"
/>
