More information

The ExprFltrQueryBldr.ConvertExprToSqlFltrStr method is used to convert an expression from XML to a SQL Server filter query string. For more information, see the Commerce Server 2002 documentation.

When you replace the Exprfltrbldr.dll file, the following parsing issues are corrected:
  • The not-equal operator does not work for the string data type.

    For example, the following code example does not work.
    <CLAUSE OPER="not-equal">
	<Property ID="UserObject.GeneralInfo.logon_name" TYPE="STRING"/>
	<IMMED-VAL TYPE="string"><![CDATA[john]]></IMMED-VAL>
</CLAUSE>
  • The not-begins-with operator does not work for the string data type.

    For example, the following code example does not work.
    <CLAUSE OPER="not-begins-with">
	<Property ID="UserObject.GeneralInfo.logon_name" TYPE="STRING"/>
	<IMMED-VAL TYPE="string"><![CDATA[s]]></IMMED-VAL>
</CLAUSE>
  • The not-contains operator does not work for the string data type.

    For example, the following code example does not work.
    <CLAUSE OPER="not-contains">
	<Property ID="UserObject.GeneralInfo.email_address" TYPE="STRING"/>
	<IMMED-VAL TYPE="string"><![CDATA[ka]]></IMMED-VAL>
</CLAUSE>
  • The not-in operator does not work for the string data type.

    For example, the following code example does not work.
    <CLAUSE OPER="not-in">
	<Property ID="UserObject.GeneralInfo.logon_name" TYPE="STRING"/>
	<IMMED-VAL TYPE="string" MULTIVAL="True">
		<VALUE><![CDATA['qq','33']]></VALUE>
	</IMMED-VAL>
</CLAUSE>
