Detailed Description

Provides meta-data for a single result column.

Member Function Documentation

getLength()

unsigned long getLength ( ) const

inline

Get column length.

Returns

The maximum length of data in the column in bytes, as reported by the server.

Note

Because the column length is returned as byte length, it could be confusing with the multi-byte character sets. For instance, with UTF8MB4 the length of VARCHAR(100) column is reported as 400 because each character is 4 bytes long.
