Hi all.

 

I have tried the sql extension somewhat as a IBM z/OS DB2 client and, sofar, it has been working out allright.

 

One strange thing I’ve found however concerns the parameterized queries which is possible to implement in a number of ways in xml-document and/or stylesheet.

 

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)"/>

 

When doing this with more than one parameter (questionmark in the sql) I get:

[jcc][10143][10845][4.9.80] Invalid parameter 1: The parameter is not specified, or registered. ERRORCODE=-4461, SQLSTATE=42815 -4461

 

When just using one parameter, after modifying whatever needs to be modified above, it executes allright.

 

After spending some time rearranging the code I found that the following set-up will work:

<xsl:value-of select="sql:addParameterWithType($db,'SPI01','string')"/>

<xsl:value-of select="sql:addParameterWithType($db,'0000004016','string')"/>                                                                                                                                  

<xsl:variable name="table" select="sql:pquery($db, $q1)"/>

 

And after doing:

<xsl:variable name="p1">SPI01</xsl:variable>

<xsl:variable name="p2">0000004016</xsl:variable>

<xsl:value-of select="sql:addParameterWithType($db,$p1,'string')"/>

<xsl:value-of select="sql:addParameterWithType($db,$p2,'string')"/>

 

It actually works so the long and the short of it is that there is a workaround. The original problem is still there however so my question is:

 

Has anybody done the original pattern with more than one parameter, if so, what have I done wrong?
