RE: SQL numeric field: edit to an alpha field

Thanks

What works for an SQL update to ONE file with a join to get values from another file?

The SQL Iseries books I have discuss separately JOINs and UPDATEs, but never both.

Does a join with update have to use the EXISTS predicate?

Or can the JOIN keyword be used with UPDATE?

For example is there a way to make this work for a join update:

UPDATE fileA set A.field1 = B.field1 join fileB on A.cust = b.cust where cust-active = 'Y'

With the scalar functions CHAR or VARCHAR the numeric fields are converted
into characters with decimal point and sign and left adjusted.
If you need the content to be right adjusted you may use something like
this:

Update MyTable
Set MyField = Right(Space(10), VarChar(NumFld), 10);

Betreff: SQL numeric field: edit to an alpha field

Can I use UPDATE in SQL with a JOIN to populate an alpha field in fileA with
a numeric field from fileB and have it edited to drop in a decimal point and
sign?

Thanks
