How can I use a function say digits with Spring JPA and native query and DB2-CodePudding

I want to be able to use this function and them pass the parameter. But I get this error, it is almost that spring jpa or java prepared statements are not allowing me to do this.

The code looks like the following in the logs.

Hibernate: UPDATE DB2PROD.GLOBAL_TABLE

SET CONTRACT_ID = DIGITS( ? ) WHERE GLOBAL_ID = ?

@Query(value = "UPDATE DB2PROD.GLOBAL_TABLE \n"  
        " SET CONTRACT_ID = DIGITS( :indicator ) \n"  
        "   WHERE GLOBAL_ID = :id ", nativeQuery = true)
int update(final Integer indicator, final String id);

And the error:

CodePudding user response：

Db2 can't determine a data type of the parameter in the DIGITS (?) expression.
You must define it explicitly with CAST like:
DIGITS (CAST (? AS INT))
or
DIGITS (CAST (? AS DEC (5)))
etc.
