ON DUPLICATE KEY UPDATE is executed, the LASTINSERTID function always returns the next auto incremented value even though only update occurs. That is, regardless of whether or not a row is inserted or updated, the INSERT. ON DUPLICATE KEY UPDATE always increments the auto-increment column by 1. After 5.1.12 this is supposedly no longer necessary, however I found an exception to that today. If you have an autoincrement pk, and a unique key on say an email address, and the 'on duplicate update' triggers based on the email address, note that the lastinsertid' will NOT be the autoincrement value of the updated row.
OpenSSL can generate several kinds of public/private keypairs. RSA is the most common kind of keypair generation. Other popular ways of generating RSA public key /. I am having problem finding a command that would generate a public and private key pair using OpenSSL. Could someone show me some example code of this in action. Oct 12, 2016 Angela from the API support team walks through how to generate a public private key pair using OpenSSL and register a private application. If you want to try integrating to Xero, partner. Openssl generate public private key.
A query involving GROUP BY
on a TIMESTAMP
column resulted in a duplicate entry for key (ER_DUP_ENTRY
Monster hunter generations 3 star key quests. ) error. This problem arose when TIMESTAMP
values were inserted into a table using a given setting for the time zone and these values were later fetched after the time zone setting had been changed, such that at least some of the inserted TIMESTAMP
values occurred during the hour that the time changed from standard to daylight time (DST) in the new time zone, during which time the same TIMESTAMP
value can exist twice. Now, when the server would otherwise return the error DUPLICATE ENTRY FOR KEY 'group_key
', if the grouping involves a TIMESTAMP
column, it instead raises the error Grouping on temporal is non-deterministic for time zones having DST. Please consider switching to UTC for this query.
In addition, it is suggested to set explicit_defaults_for_timestamp
to ON
as well as one or more of MODE_NO_ZERO_IN_DATE
, MODE_NO_ZERO_DATE
, or MODE_INVALID_DATES
as part of the server SQL mode to help avoid this issue. (Bug #90398, Bug #27970159)
