在sql语法里面定义变量
DECLARE @EmployeeName varchar(50)
set @EmployeeName = '{0}'
DECLARE @departmentGuid varchar(50)
declare @Leader int
select @departmentGuid = g_id_bm,@Leader = bLeader from sz_bm_ywy where s_mch = @EmployeeName
if (@@rowcount = 0) return
if ( @Leader = 1 )
begin
declare @Depth int
select @Depth = i_depth from sz_tree_bm where g_id = @departmentGuid
if (@@rowcount = 0) return
if(@Depth = 1)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent1 = @departmentGuid)
if(@Depth = 2)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent2 = @departmentGuid)
if(@Depth = 3)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent3 = @departmentGuid)
if(@Depth = 4)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent4 = @departmentGuid)
if(@Depth = 5)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent5 = @departmentGuid)
if(@Depth = 6)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent6 = @departmentGuid)
if(@Depth = 7)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent7 = @departmentGuid)
if(@Depth = 8)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent8 = @departmentGuid)
if(@Depth = 9)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent9 = @departmentGuid)
if(@Depth = 10)
select g_id from sz_bm_ywy where g_id_bm in ( select g_id_expand from sz_tree_extend where g_id_parent10 = @departmentGuid)
end
if ( @Leader = 0 )
select g_id from sz_bm_ywy where s_mch = @EmployeeName
注解:
1.
begin
end
相当于C#里面的
{ }
2. (@@rowcount 是全局变量 系统自带的 返回执行的行数
3. 判断是否为空 使用下面的例子
if (@ReceiveMoney is null) set @ReceiveMoney = 0;
4. IF 分支可以这样使用
if @InvoiceDate_old is null
begin
//do something
end
else
begin//do something
end
