This article will explain in detail what to do when there is a problem with the insertion of oracle into the clob field. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

1. Use the insert statement to insert the clob field. If the insert content exceeds 4000, the string will be prompted to be too long. The way to handle this is to declare that the inserted field is of type clob, as follows:

InsertSql = "DECLARE email_text clob: ='% s'; begin insert into emails values ('% ringing recording% s tracking of key stocks (% s)','0 stocks tracking'); end;"% (

Email_text,id, contactEamilAddress, dateInput)

Updating the above method will report the following error:

Cx_Oracle.DatabaseError: ORA-06550: line 1, column 28:

PLS-00172: string literal too long

Change it to the following method, and put the parameters in a single array:

InsertSql = "insert into business_EMAILS values (: 1, 1, 1, 2, 3, 3, 4, 1, 5)"

Params = [id, contactEamilAddress, email_text,' key stock tracking ({0}) '.format (dateInput), contactUserId]

Cur.execute (insertSql,params)

Conn.commit ()

two。 With the result set of python, when the clob field is read, it is converted to str type processing, as follows:

Cur_bbc.execute ("select t.times, t.rowid from emails t where t.email_status ='0'")

Res = cur_bbc.fetchall ()

For record in res:

Id = record [0]

To_email = record [1]

To_email_list = to_email.split (",")

Email_text = record [2] .read ()-- clob type

This is the end of the article on "what to do if there is a problem with oracle inserting clob fields". I hope the above content can be of some help to you, so that you can learn more knowledge. if you think the article is good, please share it out for more people to see.
