TYPO3 Core

MySQL supports an extension for optionally specifying the display width of integer data types in parentheses following the base keyword for the type. For example, INT specifies an INT with a display width of four digits. This optional display width may be used by applications to display integer values having a width less than the width specified for the column by left-padding them with spaces. (That is, this width is present in the metadata returned with result sets. Whether it is used or not is up to the application.)

The display width does not constrain the range of values that can be stored in the column. Nor does it prevent values wider than the column display width from being displayed correctly. For example, a column specified as SMALLINT has the usual SMALLINT range of -32768 to 32767, and values outside the range permitted by three digits are displayed in full using more than three digits.

Thus the correct translation for INT would be INT / INTEGER / INT4.

More discrepancies show up with other field types, resulting in the install tool database compare showing changes that are never going to get resolved.

TINYTEXT will be created as VARCHAR and reported as VARCHAR
TEXT and MEDIUMTEXT will be created/reported as LONGTEXT
