A usage for getting down from the Internet OracleSent Email Stored Procedure. You can directly call this stored procedure by sending an email. The parameter meanings are described. The Code is as follows: Create or replace procedure procsendemail, p_pass varchar2 default null, p_filename varchar2 default null, p_encode varchar2 default 'bit 7') authid CURRENT_USER is/*: use Oracle to send mail. Main functions: 1. Support for multiple recipients. 2. Support for Chinese Characters 3. CC users 4. Support for attachments larger than 32 K 5. Support for multi-line bodies 6. Support for multiple attachments 7. Support for text attachments and binary attachments 8. Support for HTML Format 8. Supported: suk parameter description: p_txt: Mail body p_sub: Mail title p_sendoraddress: sender email address p_receiveraddress: Receiving address, which can be sent to multiple addresses at the same time. "," or "is used between addresses "; "Separate p_emailserver: Email ServerAddress, which can be a domain name or IP p_port: mail server port p_need_smtp: whether SMTP authentication is required. 0 indicates no, and 1 indicates the user name p_pass required for p_user: SMTP authentication: SMTP verification requires the password p_filename: attachment name, which must contain the complete path, for example, "d: \ temp \ a.txt ". There can be multiple attachments. The attachment names can only be separated by commas (,) or semicolons (;). p_encode: The attachment encoding conversion format, p_encode = 'bit 7' indicates the attachment of the text type p_encode = 'base64' indicates the attachment of the binary type. Note: 1. attachments of the text type cannot be sent in base64 format, otherwise Error 2.
