Azure SQL 数据库 Azure SQL 托管实例 本主题列出了 T-SQL 的外围应用以及本机编译 T-SQL 模块主体支持的功能,如存储过程 (CREATE PROCEDURE (Transact-SQL))、标量用户定义函数、内联表值函数和触发器。 有关本机模块定义的支持功能,请参阅对于本机编译的 T-SQL 模块支...
T-sql For in loop 变量循环语句 For 变量 in 循环开始的值 .. 循环结束的值(小于该值) Loop --做处理的语句 End Loop 例子: ---循环找出供应商 for i in 0 .. vendor_Total loop-- i 和 vendor_Total 在存储过程头部定义,vendor_Total 在循环之前已经赋值 if i = vendor_Total then str_vendor ...
Purpose of WHILE loops Replace cursors in Synapse SQL Next steps This article provides you with essential tips for using T-SQL loops, replacing cursors, and developing related solutions with Synapse SQL.

WHILE— Continue looping while the condition returns TRUE. Examples The following example demonstrates a solution for running different logic based on the number of items in an order. It provides the same functionality as the example for SQL Server flow control. However...
'DISABLE_OPTIMIZED_NESTED_LOOP' 指示查询处理器在生成查询计划时不要对优化的嵌套循环联接使用排序作(批处理排序)。 此提示名称等效于 跟踪标志 2340。 此提示也适用于显式排序和批处理排序。 'DISABLE_OPTIMIZER_ROWGOAL' 导致SQL Server 生成计划,该计划不会对包含以下关键字的查询使用行目标修改:- TOP- OPTION...
Can we use While loop in CTE? can we write DDL command in Stored Procedure? Can wildcards be used on datetime column? can you add colour to a fields output in T-SQL? Can you change the value of yes or no instead of true or false use data type (BIT) ? Can you have a TRY CATC...
When executing the procedure from a Transact-SQL batch or another stored procedure, avoid using a cursor with the natively compiled stored procedure. When creating a natively compiled stored procedure, rather than using a cursor, use set-based logic or a WHILE loop. Feature Non-constant parameter...
While I waited…and waited for my Utility data to be inserted into my Azure database, I did some poking around to see if it was even possible to restore a local SQL Server 2014 backup to an Azure database. Guess what, I found something (And there was much rejoicing). On CodePlex, ...
For example, older T-SQL error handling might look like this: DECLARE @Error INT; INSERT INTO Employees (EmployeeID, Name) VALUES (1, 'John'); SET @Error = @@ERROR; IF @Error <> 0 GOTO ErrorHandler; INSERT INTO Employees (EmployeeID, Name) VALUES (2, 'Jane'); SET @Error = @...
Create a procedure to loop throughSourceTableand insert rows. Note There are syntax differences between T-SQL for theCREATE PROCEDUREand theCURSORdeclaration. For more information, seeStored Procedures. CREATE PROCEDURE LoopItems() BEGIN DECLARE done INT DEFAULT FALSE; DECLARE...
