However, it is not difficult in MySQL to create partitioning schemes based on DATE, TIME, or DATETIME columns, or based on expressions making use of such columns. When partitioning by KEY or LINEAR KEY, you can use a DATE, TIME, or DATETIME column ... This section discusses the types of partitioning which are available in MySQL ...

Often the problem is related to the MySQL accounts that the server permits client programs to use when connecting. See Section 6.2, “Access Control and Account Management”, and Section 6.2.17, “Troubleshooting Problems Connecting to MySQL”.

This section discusses the relationship of partitioning keys with primary keys and unique keys. The rule governing this relationship can be expressed as follows: All columns used in the partitioning expression for a partitioned table must be part ...

Note When using internal_tmp_disk_storage_engine=INNODB, queries that generate on-disk internal temporary tables that exceed InnoDB row or column limits return Row size too large or Too many columns errors. Presence of any string column with a ...

For an event, an error occurs at event execution time if the account does not exist. Stored programs (procedures, functions, triggers, and events) and views are defined prior to use and, when referenced, execute within a security context that ...
https://dev.mysql.com/doc/refman/5.7/en/performance-schema-statement-tables.html
A query that fails to parse differs from a query that parses but fails due to an error during execution. Consequently, there is no parsing at runtime and the type of each statement is known by the time it executes. The setup_timers table contains a ...Statement events occur at a high level of the event ...

Different settings work best for servers with light, predictable loads, versus servers that are running near full capacity all the time, or that experience spikes of high activity. Preventing one-time operations such as table scans from interfering ...Because the InnoDB storage engine performs many of its optimizations automatically, many performance-tuning tasks involve monitoring to ensure that the database is performing well, and changing configuration options when performance ...
https://dev.mysql.com/doc/refman/5.7/en/enterprise-encryption-usage.html
OpenSSL also imposes a maximum key length of 10,000 bits and 16,384 bits for DSA and RSA keys, respectively, for create_asymmetric_priv_key(), and a maximum key length of 10,000 bits for create_dh_parameters(). If those maximum values are too high, ... To use MySQL Enterprise Encryption in applications, invoke the functions that are appropriate for the operations you wish to ...
https://dev.mysql.com/doc/refman/5.7/en/binary-log-setting.html
Some statements require a lot of execution time on the source, but result in just a few rows being modified. It is possible to change the logging format to STATEMENT, but doing so at runtime leads very rapidly to errors because InnoDB can no longer ...The logging format also can be switched at runtime, although note that there are a number of situations in which you cannot do this, as discussed later in this ...
https://dev.mysql.com/doc/refman/5.7/en/create-table-generated-columns.html
As of MySQL 5.7.10, if expression evaluation causes truncation or provides incorrect input to a function, the CREATE TABLE statement terminates with an error and the DDL operation is rejected. If a generated column is indexed, the optimizer ...
