Can you try the current version 2.7.1?

Well, I’m sorry to say that it does not work for me, I get:

Line #51; Column #25; Error in Query

When fiddling around however it seems that there is something amiss in the use of:
<!-- Build a CSV list of parameter types -->
<xsl:param name="q1type" select="int" />
Whenever I try to make a list, e.g. “int,string” (which would be a proper CSV list to \
                my understanding) I get:
javax.xml.transform.TransformerException: javax.xml.transform.TransformerException: \
Ytterligare otillåtna tecken: ',', 'string' which is OK so I try to do an alternate \
pquery invocation: <xsl:variable name="table" select="sql:pquery($db, $q1, \
'int,string')"/> , I get: \
file:///C:/xalan-j_2_7_0/samples/extensions/sql/pquery/dbtest.xsl; Line #51; Column \
#25; Error in Query

When moving the type definitions into the Query structure (attribute “type”) and \
removing the third parameter from the “sql:pquery” statement  it works all the time \
regardless of the type values I enter (e.g. string instead of int).

All tests above done with the Derby database. I will try some more on z/OS DB2 after \
New Year.

So, till then: Happy Holidays…….

Hi,

I have no direct expericence with the Sql extension, but I think you should use
<xsl:variable name="qparam" select="//QUERY/*"/>
- otherwise it may assume that you want to add only 1 parameter (the 1 QUERY element) \
with a text value of SPI010000004016

Best regards

What I would like to do is to have  a xml fragment containing the parameter values:
<QUERY>
<KOD_TXT_GRP>SPI01</KOD_TXT_GRP>
<KODTXT>0000004016</KODTXT>
</QUERY>
And, in the stylesheet have the following code:

<xsl:param name="q1" select="'SELECT HANDAT,VALFRI_TEXT_RAD FROM DB2T.SPATTXT WHERE \
KOD_TXT_GRP = ? AND KODTXT = ?'"/> <xsl:variable name="qparam" select="//QUERY"/>
<xsl:value-of select="sql:addParameterFromElement($db,$qparam)"/>
<xsl:param name="q1type" select="'string,string'"/>
<xsl:variable name="table" select="sql:pquery($db,$q1,$q1type)"/>
