A common database can be used for all the tables shredded with a given mapping. This example shows how to use the defaultDatabase option.

Before running the example, ensure the test user is created with the required permissions and the required tables are created. See Setting Up the XSLT_SHRED_BATCH and XSLT_SHRED Examples for details.

Populate the staging table used to store the XML source document.

DELETE Input_Docs;
DELETE DefaultValue2;


Call the XSLT_SHRED_BATCH stored procedure with the stylesheet mapping to shred the XML data stored in the staging input table. The following arguments are used for the call.

  • The queryString is sel * from xsltuser.Input_Docs.
  • The xsltMapping argument is supplied by invoking the CREATEXML function with a stylesheet as input. This stylesheet will be applied to the XML document.
  • The externalContext is NULL for this example.
  • The resultCode is returned in :res. A successful operation returns 0.
CALL TD_SYSXML.XSLT_SHRED_BATCH('sel * from xsltuser.Input_Docs', CREATEXML('<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/Root">
     <xsl:for-each select="AllTypes">
       <byteintc genexp="cast(? as byteint)">
         <xsl:value-of select="Numeric/Byteintc"/>
       <smallintc><xsl:value-of select="Numeric/Smallintc"/></smallintc>
       <intc default="120"><xsl:value-of select="Numeric/Intc"/></intc>
       <floatc><xsl:value-of select="Numeric/Floatc"/></floatc>
</xsl:stylesheet>'), '',:res);
Result: To view the updated data in the target table, run: SELECT * FROM DefaultValue2;
byteintc  smallintc         intc                  floatc
