The MySQL server can operate in different SQL modes, and can apply these modes differently for different clients, depending on the value of the sql_mode system variable. DBAs can set the global SQL mode to match site server operating requirements, ...

In this section we provide a detailed example illustrating how to add new NDB Cluster data nodes online, starting with an NDB Cluster having 2 data nodes in a single node group and concluding with a cluster having 4 data nodes in 2 node groups.

Prior to MySQL 8.0, bit functions and operators required BIGINT (64-bit integer) arguments and returned BIGINT values, so they had a maximum range of 64 bits. Non-BIGINT arguments were converted to BIGINT prior to performing the operation and ...

An implication of this is that ABS(-9223372036854775808) produces an error because the result cannot be stored in a signed BIGINT value. mysql> SELECT ABS(2); -> 2 mysql> SELECT ABS(-32); -> 32 This function is safe to use with BIGINT values. mysql> ...ABS(X) Returns the absolute value of X, or NULL if X is ...

An atomic DDL statement combines the data dictionary updates, storage engine operations, and binary log writes associated with a DDL operation into a single, atomic operation. The operation is either committed, with applicable changes persisted to ...

Otherwise, the result is an integer type (with one exception): If all integer types are all signed or all unsigned, the result is the same sign and the precision is the highest of all specified integer types (that is, TINYINT, SMALLINT, MEDIUMINT, ...The second syntax returns the result for the first condition that is ...

Numeric calculations are done with BIGINT or DOUBLE (both are normally 64 bits long). The general rule is that bit functions are performed with BIGINT precision, IF() and ELT() with BIGINT or DOUBLE precision, and the rest with DOUBLE precision.
https://dev.mysql.com/doc/refman/8.0/en/mysql-nutshell.html
For example, a scalar INT or even BIGINT value actually requires very few bytes, so that the remainder of this space (up to 90% or more) was taken up by padding. Such implicit casts are now performed between temporal types (DATE, DATETIME, ... This ...
https://dev.mysql.com/doc/refman/8.0/en/out-of-range-and-overflow.html
If no restrictive modes are enabled, MySQL clips the value to the appropriate endpoint of the column data type range and stores the resulting value instead. When an out-of-range value is assigned to an integer column, MySQL stores the value ...
https://dev.mysql.com/doc/refman/8.0/en/create-table-gipks.html
Beginning with MySQL 8.0.30, MySQL supports generated invisible primary keys for any InnoDB table that is created without an explicit primary key. When the sql_generate_invisible_primary_key server system variable is set to ON, the MySQL server ...
