我正在使用脚本将环境从一台服务器移植到另一台服务器。我遇到一个问题调用,catalog.create_environment_variable
其中出现错误“输入值的数据类型与'String'的数据类型不兼容”。从过程“ check_data_type_value”出来。
奇怪的是,如果我让GUI脚本输出变量,该查询将起作用
DECLARE @var sql_variant = N'\\myserver\ssisdata'
EXEC [catalog].[create_environment_variable]
@variable_name = N'FolderBase'
, @sensitive = False
, @description = N''
, @environment_name = N'Development'
, @folder_name = N'POC'
, @value = @var
, @data_type = N'String'
GO
但是,采用这种脚本方法无效。我所做的工作表明,通常通过使用nvarchar数据类型而不是varchar解决此错误消息。但是,事实并非如此。
以下脚本的第108行。我的假设是sql_variant有点奇怪,但是我不知道那是什么。
USE SSISDB;
GO
