How can I combine two columns into one column using SQL
http://www.webdeveloper.com/forum/showthread.php?68287-How-can-I-combine-two-columns-into-one-column-using-SQL Competition: low
The trick is that if column B is null or empty I want to display column A's data otherwise, I want to display column B's data Does any one know how to combine two columns into one using SQL? This is the only thing that comes to mind SELECT ColumnA AS ColumnZ FROM Table UNION SELECT ColumnB AS ColumnZ FROM Table ORDER BY ColumnZ Any hints, ideas, or suggestions are welcome!

If data is huge, if there are any Non-Clustered indexes that are not build on primary key or unique key, then disable those indexes, loading will be much faster. How can I fix? I have SQL Server 2008 and Visual Studio 2008 and am trying to automatically insert new records into a child table based on new inserts into its parent table

Until 1996, the National Institute of Standards and Technology (NIST) data management standards program certified SQL DBMS compliance with the SQL standard. CTEs can be also be recursive by referring to themselves; the resulting mechanism allows tree or graph traversals (when represented as relations), and more generally fixpoint computations
SELECT Clause (Transact-SQL)

Remarks The length of data returned for text or ntext columns that are included in the select list is set to the smallest value of the following: the actual size of the text column, the default TEXTSIZE session setting, or the hard-coded application limit. The SQL Server Database Engine raises exception 511 and rolls back the current running statement if either of the following behavior occurs: The SELECT statement produces a result row or an intermediate work table row exceeding 8,060 bytes
SQL DISTINCT

Please consider the example below: SELECT DISTINCT LastName, City FROM Users What the above statement will do is to return all unique combinations between LastName and City columns

Here is an example of SQL DISTINCT clause: SELECT DISTINCT Column1 FROM Table1 As you can see the DISTINCT keyword goes immediately after the SELECT clause and is then followed by a list of one or more column names

The SQL SELECT DISTINCT Statement In a table, a column may contain many duplicate values; and sometimes you only want to list the different (distinct) values
