Question

我不知道为什么我的代码试图将变量中的查询转换为数据类型INT。更令人陌生的是，我在Linqpad上运行的代码很好。然后我将代码粘贴到Report Builder 3.0中并在查询视图中再次进行测试，该工作正常。接下来，我去报告视图并运行一次。这也很好。然而，一旦我使用新的指定参数再次运行它，它就会抛出错误并告诉我检查本地计算机。

代码：

DECLARE @item varchar(50)               = '%'
DECLARE @lp varchar(50)                = '1231888'
DECLARE @loc varchar(10)                = '%'
DECLARE @lot varchar(30)               = '%'
DECLARE @trans_type varchar(2)         = '%'
DECLARE @desc varchar(20)              = '%'
DECLARE @whse varchar(4)               = '%'
DECLARE @u_m varchar(20)               = '%'
DECLARE @emp_num varchar(20)           = '%'
DECLARE @ref_num varchar(20)           = '%'
DECLARE @fglot varchar(20)             = '%'
DECLARE @shift varchar(20)             = '%'
DECLARE @truckid varchar(20)           = '%'

DECLARE @createdate datetime2           = NULL
DECLARE @createdate_string varchar(19) = CAST(@createdate AS nvarchar(19))
DECLARE @ref_line_suf int               = 4
DECLARE @ref_line_suf_string varchar(2) = CAST(@ref_line_suf AS varchar(2))
DECLARE @qty decimal                    = NULL
DECLARE @qty_string varchar(30)         = CAST(@qty AS varchar(30))

错误屏幕截图：

使用创建问题的参数查询打印输出（注意：这是来自Linqpad，没有问题。报表生成器3.0中出现问题）：

SELECT TOP (10000)

FROM 

  isw_lptrans AS t 

WHERE

  1=1 AND t.lp_num LIKE '%1231888%' AND t.ref_line_suf = 4

SQL：存储在@query中的查询一直试图转换为数据类型INT
