SQL Server - 如何插入到 Varbinary(Max) 列中?

2021-09-10 00:00:00 tsql sql-server

我有一张如下所示的表格.我真的不想创建一个 C# 应用程序来将行插入到这个表中，如果我可以避免的话，因为 VarBinary 列.我的目的是在此列中存储一个 Crystal 报表 .RPT 文件.是否有我可以执行的 T-SQL 语句来将行插入/更新到此表中，并包含一个 .RPT 文件?

I have a table that looks as follows below. I don't really want to create a C# application to insert rows into this table, if I can avoid it, because of the VarBinary column. My intent is to store a Crystal report .RPT file in this column. Is there a T-SQL statement I can execute to insert/update rows into this table, and include an .RPT file?

CREATE TABLE [Report].[MesReport](
    [MesReportID] [int] IDENTITY(1,1) NOT NULL,
    [ParentID] [int] NOT NULL,
    [ReportTitle] [nvarchar](80) NOT NULL,
    [ReportName] [nvarchar](80) NOT NULL,
    [DatabaseServer] [nvarchar](80) NOT NULL,
    [DatabaseName] [nvarchar](50) NOT NULL,
    [Login] [nvarchar](80) NOT NULL,
    [ReportFile] [varbinary](max) NULL,

推荐答案

你可以把它变成一个像

DECLARE @VB varbinary(max)
SELECT @VB =BulkColumn FROM OPENROWSET(BULK
     N'C:\YourReport.rpt', SINGLE_BLOB) AS Document

然后您可以在插入语句中使用

that you can then use in an insert statement
