Hi,

I have written an update query in AS400.

SQL

update s1 set age=(select b.age from s1 a, s2 b where a.id = b.id)
where name in (select b.name from s1 a, s2 b where a.name = b.name)

This query is to update age in the table 'S1', when ID and name matches with the table S2.

But it's showing Data conversion or data mapping error

Please help

Are you sure the below condition is correct ?

where a.id = b.name

Please post some rows of each table for example.

Solution 1

It is possible that the query

SQL

(select b.age from s1 a, s2 b where a.id = b.name)

is returning multiple rows hence you can't set them to a single value in age.
