Varchar fields can be of any size up to a limit, which varies by databases: an Oracle 11g database has a limit of 4000 bytes, [1] a MySQL 5.7 database has a limit of 65,535 bytes (for the entire row) [2] and Microsoft SQL Server 2008 has a limit of 8000 bytes (unless varchar(max) is used, which has a maximum storage capacity of 2 gigabytes). [3]
This limit applies to number of characters in names, rows per table, columns per table, and characters per CHAR/VARCHAR. Note (9): Despite the lack of a date datatype, SQLite does include date and time functions, [ 83 ] which work for timestamps between 24 November 4714 B.C. and 1 November 5352.

Some languages have character types that are too small to represent all Unicode characters. These are more properly categorized as integer types that have been given a misleading name. For example C includes a char type, but it is defined to be the smallest addressable unit of memory, which several standards (such as POSIX) require to be 8 bits.
To define a character variable, the programmer normally appends the variable type VARCHAR2 to the name definition. There follows in brackets the maximum number of characters the variable can store. Other datatypes for character variables include: varchar, char, long, raw, long raw, nchar, nchar2, clob, blob, and bfile.
