Database 如何使用python在IBMDB2数据库中存储映像？

我可以使用python文件连接到ibmdb2数据库，我可以通过它运行各种命令，但是如何将图像存储到DB2数据库表中的列中呢？我已经在我的表中创建了一个BLOB类型的列。

为什么不看看github上ibm_db的测试用例呢

它们显示了一个测试用例，用于使用

PARAM_FILE

选项

ibm_db.bind_PARAM（）

将图像文件的内容复制到

BLOB

列中

请参见testcase[此处][1]

尽管测试可能已过期，但下面的代码片段 显示通过PARAM_file方法使用ibm_db 3.0.1版（成功地将jpg文件插入BLOB列）工作的参数：

jpg_file="/home/some_user/Pictures/houston.jpg"  # path to the image file

# table my_pics already exists with a blob colum called jpg_content of appropriate length
# The database already contains a table called MY_PICS in the current schema
# with a BLOB column named JPG_CONTENT
#

insert_sql = "INSERT INTO my_pics(jpg_content) values(?)"
try:
    stmt = ibm_db.prepare(conn, insert_sql)
    print("Successfully prepared the insert statement")
except:
    print("Failed to compile the insert statement")
    print(ibm_db.stmt_errormsg(stmt))
    ibm_db.close(conn)
    sys.exit(1)

# link a file-name to the parameter-marker of the insert-statement (target column is BLOB)

try:
    rc = ibm_db.bind_param(stmt, 1, jpg_file, ibm_db.PARAM_FILE,ibm_db.SQL_BLOB )
    print("Bind returned: "+str(rc))
    print("Successfully bound the filename to the parmameter-marker")

except:
    print("Bind returned: "+str(rc))
    print("Failed to bind the input parameter file")
    print(ibm_db.stmt_errormsg(stmt))
    ibm_db.close(conn)
    sys.exit(1)

try:
    ibm_db.execute(stmt)
    print("Successfully inserted jpg file into blob column")
except:
    print("Failed to execute the insert to blob column")
    print(ibm_db.stmt_errormsg(stmt))
