Question

我只是希望能够将jpg数据从单个记录导出到文件，而无需每次都编写程序。

查询：

select Media from tbl_GEO_ElementImage where ElementImageID = 64902

Answer 1

使用命令行BCP实用程序：

c:\temp\>bcp "select Media from tbl_GEO_ElementImage where ElementImageID = 64902" queryout "001.jpg" -T

提示时，请提供以下答案：

    Enter the file storage type of field Media [image]: <Enter>
    Enter prefix-length of field Media [4]: 0
    Enter length of field Media [0]: <Enter>
    Enter field terminator [none]: <Enter>

Do you want to save this format information in a file? [Y/n] n

Answer 2

我最终编写了一个命令行实用程序，允许简单无人值守地导出多个图像记录。

Usage:
RunSQLOLEDB "[connection string]" "[query]"

e.g.
To extact all images from table Image into separate files 1.jpg, 2.jpg, etc.
SQLImageOut "Provider=SQLOLEDB;Data Source=(local);..." "SELECT CONVERT(varchar(50), ImageID)+'.jpg', ImageData from Image"
or        
SQLImageOut @ConnectionString.txt @Query.sql
