Re: Update with subquery I agree! is the not operator for most other languages but I didn't know you could use it for SQL.
I've done a bit of searching and it appears that is the not operator specified in the ANSI 92 standard but that many RDMS' support! because that's what most languages now use. The list of selectexpr terms comprises the select list that indicates which columns to retrieve. Terms specify a column or expression or can use shorthand: A select list consisting only of a single unqualified can be used as shorthand to select all columns from all tables: iSeries SQL Programming: Youve Got the Power!

The ONLY way to access data on Microsoft SQL (reprinted from IBM Manual) CREATE TRIGGER SQL Subquery. Subquery or Inner query or Nested query is a query in a query. SQL subquery is usually added in the WHERE Clause of the SQL statement. Most of the time, a subquery is used when you know how to search for a value using a SELECT statement, but do not know the exact value in Subqueries in SELECT Statements. For the syntax that you use to create a condition with a subquery, see the Informix Guide to SQL: Syntax.
Using ALL. Use the keyword ALL preceding a subquery to determine whether a comparison is true for every value returned. iSeries query changes selected RRN of subquery result rows. the function returns the relative record number of the first table in the outer subselect of the view, common table expression, or nested table expression.

You can use the SELECT statement to retrieve a specific row or retrieve data in a specific way. If SQL is unable to find a row that satisfies the search condition, an SQLCODE of 100 is returned.
