使用用SQL语句从电脑导入图片到数据库的方法

 --创建图片表 CREATE TABLE W_PIC ( ID INT,        --编号 WPATH VARCHAR(80),  --完整路径 PIC VARCHAR(80),  --图片名称，不带后缀 img image      --图片内容 ) --图片表中插入数据 INSERT INTO W_PIC(ID,WPATH,PIC) SELECT 1, 'C:\Users\w\Desktop\产品图片\2#加工图34-C专用.jpg-600','2#加工图34-C专用' UNION ALL SELECT 2, 'C:\Users\w\Desktop\产品图片\129.jpg-600','129' --创建游标 DECLARE CUR_PIC CURSOR FOR SELECT ID,WPATH,PIC FROM W_PIC; DECLARE @ID int, @PATH VARCHAR(80), @PIC VARCHAR(80), @STR VARCHAR(100); OPEN CUR_PIC; FETCH NEXT FROM CUR_PIC INTO @ID, @PATH, @PIC; WHILE @@FETCH_STATUS=0 BEGIN SET @STR=STR(@ID); --插入图片数据 EXECUTE ('UPDATE W_PIC SET img=(SELECT * FROM OPENROWSET(BULK N'''+@PATH+''', SINGLE_BLOB) AS Photo) WHERE ID='+@STR); FETCH NEXT FROM CUR_PIC INTO @ID, @PATH, @PIC; END CLOSE CUR_PIC; DEALLOCATE CUR_PIC;
