SELECT F1 FROM Evaluation.CalculatedLimits_' + CAST(@PlantLineMapId as varchar) + ' WHERE PROCESS = 2 AND TIMESTAMP = @TempStartDate,121)' and pass @tempStartDate as a parameter to your dynamic SQL: Copy EXEC sp
When you can make something run better, why would you ever choose to not do so? Take a look atJeff Moden's article "The 'Numbers' or 'Tally' Table: What it is and how it replaces a loop" (http://www.sqlservercentral.com/articles/T-SQL/62867/)[/url]. ...
Sometimes there is a need to loop through records and process a record at a time in a Transact-SQL script or stored procedure in Microsoft SQL Server. It may not be the most efficient approach, but it may be the only option. In this tutorial, we look at how to create a WHILE loop ...
However, in the Execution plan, there are many iterators for different operations, but in this article, we will learn one iterator only, that is, the Nested Loop Join. It is a physical join type iterator. Whenever you join a table to another table logically, the Query Optimizer can choose...
How a loop in SQL Server works and affects query performance? Loop defines in three sections: Initiate, Condition and Increment. In SQL Server, a loop is characterized to perform such queries with the number of cycles in the body. Those operations can be Select, Ins...
使用循环语句:可以使用循环语句(如WHILE或LOOP)结合条件来逐行处理查询结果。以下是一个示例: 代码语言:txt 复制 DECLARE @id INT DECLARE @name VARCHAR(50) DECLARE @rowCount INT SET @rowCount = (SELECT COUNT(*) FROM your_table) SET @id = 1 WHILE @id <= @rowCount BEGIN SELECT @name = name ...
Intentionally creating an infinite loop is risky, and it is all too easy to crush a server with a single misstep. This particular form is also wasteful, because you always have to perform one more iteration of the loop (which might be a lot more complex than the sample above) in order...
Can we optimise While Loop in sql server for large number of data? Can we pass parameters to the trigger?(Beginner) Can we RAISERROR inside MERGE Statement Can we select Bottom 1000 rows of a database Table from SSMS 2008 R2? Can we set value in a variable inside a select statement ca...
A. Use BREAK and CONTINUE with nested IF...ELSE and WHILE In the following example, if the average list price of a product is less than $300, theWHILEloop doubles the prices and then selects the maximum price. If the maximum price is less than or equal to $500, theWHILEloop restarts...
