Which of these queries is the faster? NOT EXISTS: SELECT ProductID, ProductName FROM Northwind..Products p WHERE NOT EXISTS ( SELECT 1 FROM Northwind..[Order Details] od WHERE p.
The @CustID means it's a parameter that you will supply a value for later in your code. This is the best way of protecting against SQL injection. Create your query using parameters, rather than concatenating strings and variables. The database engine puts the parameter value into where the placeholder is, and there is zero chance for SQL injection.
I'm looking for an efficient way to convert rows to columns in SQL Server, I heard that PIVOT is not very fast, and I need to deal with lot of records. This is my example: Id Value ColumnName 1 John
I can select all the distinct values in a column in the following ways: SELECT DISTINCT column_name FROM table_name; SELECT column_name FROM table_name GROUP BY column_name; But how do I get the row
All previous version of SQL Server Express were available in both web and full downloads. But I cannot find full download of SQL Server® 2016 Express. Does it exist? Asked the same question on MSDN
From SQL Server 2012 you can use the EOMONTH function. Returns the last day of the month that contains the specified date, with an optional offset. Syntax
In addition to the CAST and CONVERT functions in the previous answers, if you are using SQL Server 2012 and above you use the FORMAT function to convert a DATETIME based type to a string.
