SQL server游标基本结构

简单游标遍历数据：

BEGIN 
    DECLARE QZ_cursor CURSOR SCROLL FOR  
    SELECT NAME FROM USERINFO 
    OPEN QZ_cursor 
    DECLARE @v_ID VARCHAR(100) 
    FETCH NEXT FROM QZ_cursor INTO @v_ID
    WHILE @@FETCH_STATUS=0
    BEGIN  --loop
		PRINT @v_ID
        FETCH NEXT FROM QZ_cursor INTO @v_ID
    END
    CLOSE QZ_cursor	 
    DEALLOCATE QZ_cursor   
END
