I want to set the length to MAX for one of my XML fields.
XML Code:
<?xml version="1.0"?>
<BCPFORMAT xmlns="http://schemas.microsoft.com/sqlserver/2004/bulkload/format" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<RECORD>
<FIELD ID="1" xsi:type="CharFixed" LENGTH="3" />
<FIELD ID="2" xsi:type="CharFixed" LENGTH="MAXLENGTH" />
<FIELD ID="3" xsi:type="CharFixed" LENGTH="10" />
<FIELD ID="4" xsi:type="CharFixed" LENGTH="8" />
</RECORD>
<ROW>
<COLUMN SOURCE="1" NAME="Field1" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="2" NAME="Field2" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="3" NAME="Field3" xsi:type="SQLNVARCHAR"/>
<COLUMN SOURCE="4" NAME="Field4" xsi:type="SQLNVARCHAR"/>
</ROW>
</BCPFORMAT>
But 'MAXLENGTH' does not seem to work.
Error message:
bad value MAXLENGTH for attribute "LENGTH"
Any suggestions on how to put the LENGTH to maximum ?
The length of a string is limited to 4000 (nchar) or 8000 (char) type. There is no max length
-constant - AFAIC
Refer to this, "Field Attributes"
If you look up the schema meta-data just as SQL Server does, you can follow this link
http://schemas.microsoft.com/sqlserver/2004/bulkload/format/bulkloadschema.xsd
to find this
<xsd:attribute name="LENGTH" type="xsd:positiveInteger" use="required"/>
[...]
<xsd:attribute name="MAX_LENGTH" type="xsd:positiveInteger" use="optional"/>
So the length
is required
while max_length
seems to be optional
, but if you specify it, it must be a positive integer.
