Croc live sex chat granny - Updating a select statement to update

Note, however, that the data is slightly different in the Adventure Works database from what’s stored in the Adventure Works2008 database, so your results will be different than what is shown here. (Only the last example might need to be modified, which I’ll explain when we get to it.) To try out the examples in the article, you must first create the Sales Staff table, as shown in the following Transact-SQL code: Notice that I tag on a SELECT statement at the end of the code to retrieve the new content in the Sales Staff table.

You can issue an UPDATE statement against a table or updateable view, as long as the statement modifies data in only one base table at a time.

By using an UPDATE statement, you can modify data in individual rows, sets of rows, or all rows in a table.

The Oracle UPDATE statement is used to update existing records in a table in an Oracle database.

There are 2 syntaxes for an update query in Oracle depending on whether you are performing a traditional update or updating one table with data from another table.

Or if an alias exists, the alias should exist in the FROM clause. If the WHERE condition is used and is true for a specific row, then the an update is performed on that row.

If the WHERE clause is omitted, then the UPDATE command updates all records of a table.

update Master Tbl set Total X = (select sum(X) from Detail Tbl where Detail Tbl. ID) update Master Tbl set Total Y = (select sum(Y) from Detail Tbl where Detail Tbl. ID) update Master Tbl set Total Z = (select sum(Z) from Detail Tbl where Detail Tbl. I'm not sure whether I'm bumping up against the limits of my particular database (Advantage), or the limits of my SQL. I upvoted you here because you just bailed me out of a tough SQL situation. UPDATE Master Tbl SET Total X = (SELECT SUM(X) from Detail Tbl where Detail Tbl. ID), Total Y = (SELECT SUM(Y) from Detail Tbl where Detail Tbl. ID), Total Z = (SELECT SUM(Z) from Detail Tbl where Detail Tbl. So if nothing else works, this might give you a slight improvement.

I've also tried versions that omit the "group by" clause. 1 Charles - I stumbled on to this question - and your answer - as I started to ask my own question. If your DB supports it, concatenating all 3 updates into one sql string will save on server-round-trips if querying over the LAN.

To fix it, we run the following SQL statement: IMPORTANT: When using the UPDATE statement, pay special attention to make sure that some type of filtering criteria is specified. UPDATE Store_Information SET Sales = 800 WHERE Store_Name = 'Boston'; 2. What is the content of the table after the following SQL statement is executed?


  1. It will help you know what you can prepare to make him happy.11. What is that one crazy thing you have done in life? If he prefers happiness, then he like satisfying his inner needs.22.
