Home -> Community -> Usenet -> c.d.o.misc -> SQL: Updates a table based on a join
I have a situation where I need to update a table (STATUS) based on
another table (VALUES). STATUS has the following columns; name, file1,
file2, file3, date. VALUES has the following columns: name, ftp_file,
date; name joins to name, date joins to date. What I need to do is to
set the values of status.file1 = values.ftp_file where status.name =
values.name and status.date = values.date and instr(ftp_file,'A.ZIP') >
0.
The following select statement gives me the clientnames where this
match occurs
SELECT s.name
FROM status s, values v
WHERE s.name = v.name and
s.date = v.date and
instr(ftp_file,'A.ZIP') > 0;
But I can't figure out how to turn this into an UPDATE statement.
Please let me know if anyone has any insight.
