当我使用时间戳字符串时，cql 查询语句不起作用

Question

what is the problem in my code?

Answer 1

It's likely that there are special characters in the variables causing an issue. A prepared statement is a good way to insulate against that. So instead of this:

session.execute("INSERT INTO test_table(id,time) VALUES ({},{});".format(uuid.uuid1(),timestamp))

Try using a prepared statement, like this:

strCQL = "INSERT INTO test_table(id,time) VALUES (?,?);"
pStatement = session.prepare(strCQL)
session.execute(pStatement,[uuid.uuid1(),timestamp])
