As an extension to the standard, MySQL also supports the integer types TINYINT, MEDIUMINT, and BIGINT. MySQL supports the SQL standard integer types INTEGER (or INT) and SMALLINT. The following table shows the required storage and range for each ...

If only ALL_NON_LOSSY is set, but not ALL_LOSSY, then attempting a conversion that would result in the loss of data (such as INT to TINYINT, or CHAR(25) to VARCHAR(20)) causes the replica to stop with an error. Supported conversions between ...
https://dev.mysql.com/doc/refman/8.0/en/other-vendor-data-types.html
To facilitate the use of code written for SQL implementations from other vendors, MySQL maps data types as shown in the following table. These mappings make it easier to import table definitions from other database systems into MySQL. If you create ...
https://dev.mysql.com/doc/refman/8.0/en/partitioning-pruning.html
The optimization known as partition pruning is based on a relatively simple concept which can be described as “Do not scan partitions where there can be no matching values”. By limiting the search, it is possible to expend much less time and ...
https://dev.mysql.com/doc/refman/8.0/en/precision-math-examples.html
This section provides some examples that show precision math query results in MySQL. These examples demonstrate the principles described in Section 14.24.3, “Expression Handling”, and Section 14.24.4, “Rounding Behavior”. Consider the ...
https://dev.mysql.com/doc/refman/8.0/en/example-auto-increment.html
For example, if you use TINYINT, the maximum permissible sequence number is 127. See Section 13.1.2, “Integer Types (Exact Value) - INTEGER, INT, SMALLINT, TINYINT, MEDIUMINT, BIGINT” for the ranges of all the integer types. You can also ...
https://dev.mysql.com/doc/refman/8.0/en/constant-folding-optimization.html
Consider the table created by the following statement: CREATE TABLE t (c TINYINT UNSIGNED NOT NULL); The WHERE condition in the query SELECT * FROM t WHERE c < 256 contains the integral constant 256 which is out of range for a TINYINT UNSIGNED ...
https://dev.mysql.com/doc/refman/8.0/en/storage-requirements.html
For example, in NDB tables, the TINYINT, SMALLINT, MEDIUMINT, and INTEGER (INT) column types each require 4 bytes storage per record due to the alignment factor. InnoDB Table Storage Requirements NDB Table Storage Requirements Numeric Type Storage ...
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/alter-table-examples.html
For NDB tables, it is also possible to change the storage type used for a table or column. row *************************** Table: t1 Create Table: CREATE TABLE `t2` ( `c1` int(11) DEFAULT NULL ) /*!50100 TABLESPACE ts_1 STORAGE DISK */ ...
