Question

From Java I am doing the following query on DB2:

SELECT * FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ?

The field TRANSACTION_ID is a VARCHAR of length 32. I set the parameter in the preparedStatement using the setString method.

I get the error:

com.ibm.db2.jcc.am.SqlSyntaxErrorException: DB2 SQL Error: SQLCODE=-270, SQLSTATE=42997, SQLERRMC=63, DRIVER=3.59.81

    at com.ibm.db2.jcc.am.cn.executeQuery(cn.java:652)

Where the sqstate means “Capability is not supported by this version of the DB2 application requester, DB2 application server, or the combination of the two.” But I don’t use any strange functionality.

I have tried using an squ client the query:

SELECT * FROM PRV_PRE_ACTIVATION where transaction_id='A'

And it goes ok.

What is the cause of the problem?

UPDATE: The code where the statement is prepared:

s = con.prepareStatement(sSQL,
                 ResultSet.TYPE_SCROLL_INSENSITIVE,
                 ResultSet.CONCUR_UPDATABLE);

Answer 1

Try changing to a specified list of columns in the select list — my guess is you have a user defined column type (or some other type) which is not supported by your driver. For example, does the statement

SELECT TRANSACTION_ID FROM PRV_PRE_ACTIVATION WHERE TRANSACTION_ID = ?

work? If so then start adding columns in and you will find the problem column.
