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
