  • 游标的使用

    DECLARE My_Cursor1 CURSOR --定义游标
    FOR (SELECT RowGuid , ProjectRowGuid FROM [BIMPM_Base].[dbo].[ProjectPermission_Role] where SubSystemRowGuid = 'A9318399-66FE-423E-93F5-CCD7C0A471C4') --查出需要的集合放到游标中
    OPEN My_Cursor1; --打开游标
    declare @RoleRowGuid varchar(50),@ProjectRowGuid varchar(50)
    fetch next from My_Cursor1 into @RoleRowGuid,@ProjectRowGuid
    while(@@FETCH_STATUS=0)
    begin
    ---内层循环
    declare Cursor22 CURSOR for (select RowGuid from [BIMPM_Base].[dbo].[ProjectPermissionItem] where SubSystemRowGuid = 'A9318399-66FE-423E-93F5-CCD7C0A471C4')
    OPEN Cursor22
    declare @ItemRowGuid varchar(50)
    fetch next from Cursor22 into @ItemRowGuid
    while(@@FETCH_STATUS=0)
    begin
    Insert into [BIMPM_Base].[dbo].[ProjectPermission_MenuRole](ProjectRowGuid,PermissionItemRowGuid,RoleRowGuid,SubSystemRowGuid)

    fetch next from Cursor22 into @ItemRowGuid
    end
    close Cursor22

    fetch next from My_Cursor1 into @RoleRowGuid,@ProjectRowGuid ---移动游标
    end
    close My_Cursor1
