In Oracle to MySQL, VARCHAR2 (10) and number should be converted to why type?

I. VARCHAR2 (10) and number should be converted why type?

When Oracle turns into MySQL:
VARCHAR2 (10) can be turned into varchar (10)
Number depends on what type of data is stored in Oracle:
1, if the integer type, then MySQL, with an int can be;
2, if it is with a decimal place, then the numeric type is available in MySQL.

Note: MySQL does not have varchar2 (10) and number two data types

Two. Mysql varchar VS Oracle varchar2

MySQL and Oracle Do data synchronization. One of the fields in the table is set to varchar (6)in MySQL and varchar2 (6) in Oracle
But the data that can be stored normally in MySQL is synchronized to Oracle but holds Ora-12899:value too large for column error.
What is this for?

In MySQL, varchar (6) represents the ability to store 6 characters, 6 letters, or 6 digits.
Oracle VARCHAR2 (6) Represents a 6-byte storage. That is, the length of VARCHAR2 in Oracle represents the number of bytes rather than the number of characters.
One Chinese character in MySQL accounts for three bytes, and one kanji in Oracle accounts for two bytes.

Although MySQL varchar and orache varchar2 have the same length in the fields, they do not fit in Oracle.
