1. Problem your XMl Script
2. If null value not present in your columns in your table in database.The ; problem has occured.
please check below steps.
1. Are you using OCI or ODBC in your connection pool? Try it with OCI Call Interface 11g.
2.Remove the commit tag from the XML file.
<postUpdate>COMMIT</postUpdate>
=============================================================================================================
This xml file working for me.
Insert--
A couple of small adjustments got your XML to work here:
<?xml version="1.0"; encoding="utf-8"?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1";>
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name="WriteBack">
<XML>
<writeBack connectionPool="Connection Pool">
<insert> INSERT INTO FACT (PRICE,PRODUCT_KEY,REGION_KEY,SALE_UNIT,TIMEKEY,SALES_QUOTA)
values (@{c7},@{c8},@{c9},@{c10},@{c11},@{c5} ) </insert>
<update> </update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
The <writeBack> tag is written with a lower case "w".
The "connetionPool" needs an upper case "P".
Update--
I think that you have to specify also an SQL statement for the update tag, for example:
<?xml version="1.0"; encoding="utf-8"?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1";>
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name="pmet_update">
<XML>
<writeBack connectionPool="PMTCOG">
<insert> select null from dual</insert>
<update> UPDATE XREF_PMET_URL SET URL= '@{c1}' WHERE API='@{c0}'</update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
The witeback wants for both the tags (<insert></insert> and <update></update>) an SQL Statement.
Hope this help's
Thanks
