请帮忙！我从我设置的分区切换出时出错。我有下面的脚本和错误信息：

我为每个范围创建了单独的文件组

--创建分区函数

USE [ApplicationLogs]
GO
CREATE PARTITION FUNCTION [FN_SchedulerLog](datetime) AS RANGE LEFT FOR VALUES (N'2016-06-30T23:59:59.998', N'2016-07-31T23:59:59.998', N'2016-08-31T23:59:59.998', N'2016-09-30T23:59:59.998', N'2016-10-31T23:59:59.998', N'2016-11-30T23:59:59.998', N'2016-12-31T23:59:59.998')

--Create Parttion SCHEME
CREATE PARTITION SCHEME [sch_SchedulerLog] AS PARTITION [FN_SchedulerLog] TO ([FG_SchedulerLog_06_16], [FG_SchedulerLog_07_16], [FG_SchedulerLog_08_16], [FG_SchedulerLog_09_16], [FG_SchedulerLog_10_16], [FG_SchedulerLog_11_16], [FG_SchedulerLog_12_16], [PRIMARY])

请在下面对我的 SQL 查询提供任何帮助，我们将不胜感激。我不熟悉如何循环数据库来截断表。我尝试过的内容如下：

DECLARE @DynamicSQL AS VARCHAR(MAX) = '';
DECLARE @dbName     nvarchar(1000) ='SP_%%';


SELECT @DynamicSQL = @DynamicSQL + 'Use' + QUOTENAME(NAME) + ';  '
FROM sys.databases
WHERE NAME LIKE  'SP_%%';

SELECT @DynamicSQL = @DynamicSQL + 'TRUNCATE TABLE ' + QUOTENAME(NAME) + '; '
FROM sys.tables
WHERE name LIKE 'log%'


PRINT @DynamicSQL
--EXEC (@DynamicSQL)

我得到的结果如下：

Use[SP__20180314];  Use[SPAUT__06092018];

但我想要这样的东西：

Use[SP_20180314] Truncate Table log;  Use[SPAUT_06092018] Truncate Table log;

我正在尝试从 SQL Server 2016 上的数据库中截断日志表。谢谢
