![]() It's supported by recent versions of both, mysql-client and pymysql. UpdateĪs pointed out, there's binary_prefix flag which can be passed to the connection's initialiser to automatically prepend _binary prefix when interpolating arguments. Manually construct queries with hexadecimal literals INSERT INTO `table`(bin_field) VALUES(x'abcdef')Ĭhange connection charset if you're only working with binary stringsįor more details see MySQL Bug 79317. There are several solutions to it:Įxplicitly set _binary charset literal INSERT INTO `table`(bin_field) VALUES(_binary %s) Whenever MySQL sees that a string literal in a query isn't valid against current character_set_connection it will emit the warning. It is reproduced by the following: cursor.execute('''Ĭursor.execute('INSERT INTO `table`(bin_field) VALUES(%s)', (bin_value,)) To supplement existing answers, there's also an issue with the following warning when dealing with binary strings in queries: Warning: (1300, "Invalid utf8 character string: 'ABCDEF'") R.execute('SELECT added_id, id FROM xyz WHERE id = %s', key.bytes) R.execute('INSERT INTO xyz (id) VALUES (%s)', key.bytes) Results returned by the cursor? import binascii ![]() Perhaps you are incorrectly fetching / iterating over the My script is able to insert and query for the rows using the binary field as a I created a test table to try to reproduce what you're seeing: CREATE TABLE xyz ( In SQL it's often easier to deal with real TIMESTAMP types. As for timestamps, if you want to perform time/date manipulation Thanks tip: you should be able to call uuid.uuid4().bytes to get the rawīytes. The row exists when I check via mysqlclient. NOTE: I am not having problems inserting the data, just trying to retrieve it from the database. Also, as an aside, is it better to store unix epoch dates as integers or TIMESTAMP? Next, build a list of rows that you can feed into executemany: values line.split () for line in filecontent cursor.executemany (query, values) The split method splits the lines in the file on whitespace into a tuple, e.g., the string a b c is turned into the. ![]() Then to retrieve data I use a similar query: query = cursor.execute('SELECT added_id, id, data, create_date, update_date ' \Īny help would be appreciated. First, split the file into lines with file.readlines () instead of file.read (). INSERT INTO repositories (id, data, create_date, update_date) Then I create a new row in the table using the following code: data = press(json.dumps() ) DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci ENGINE=InnoDB I'm using the following schema: CREATE TABLE repositories ( I am using a 16-byte binary uuid as a primary key for the table and have a mediumblob holding zlib compressed json information. I'm having trouble getting the proper type conversions. I'm using the MySQLdb package for interacting with MySQL.
