ITERATE语句:只能用在循环语句(LOOP、REPEAT和WHILE语句)内,表示重新开始循环,将执行顺序转到语句段开头处。如果你有面向过程的编程语言的使用经验,你可以把 ITERATE 理解为 continue,意思为 再次循环。 语句基本格式如下: ITERATE label
SET @MyCounter = 0; -- Test the variable to see if the loop is finished. WHILE (@MyCounter < 26) BEGIN; -- Insert a row into the table. INSERT INTO TestTable VALUES -- Use the variable to provide the integer value -- for cola. Also use it to generate a unique letter -- for...
You typically use a Foreach Loop container with the Foreach ADO enumerator to process one row of the recordset at a time. The variable specified for the Foreach ADO enumerator must be of Object data type. For more information about the Recordset destination, see Use a Recordset Destination. ...

{ LOOP |MERGE |HASH } JOIN 指定所有联接作由LOOP JOIN整个MERGE JOINHASH JOIN查询或整个查询执行。 如果指定多个联接提示,优化器将从允许的联接中选择成本最低的联接策略。 如果在特定表对的同一查询子FROM句中指定联接提示,则此联接提示优先于两个表的联接。 不过,仍必须遵循查询提示。 表对的联接提示只能限制...
