Report "not well formed" or "cannot convert" error after storing a character string info a field.

As of version 5.0 both cases return the same error:

"Invalid string value: 'xxx' for column 't' at row 1"

Future versions will possibly introduce a new error message:

"Cannot convert character string: 'xxx' for column 't' at row 1"

well_formed_error_posposition of the first non-wellformed character in the source string
cannot_convert_error_posposition of the first non-convertable character in the source string
from_end_posposition where conversion stopped in the source string
endend of the source string
count_spacestreat trailing spaces as important data
cscharacter set of the string
uint32 Field_longstr::max_data_length ( ) const [virtual]

Get the maximum size of the data in packed format.

Maximum data length of the field when packed using the Field::pack() function.

Reimplemented from Field.

Reimplemented in Field_blob.

type_conversion_status Field_longstr::store_decimal ( const my_decimal d) [virtual]

Decimal representation of Field_str.

dvalue for storing
Field_str is the base class for fields implemeting [VAR]CHAR, VAR[BINARY], BLOB/TEXT, GEOMETRY. String value should be converted to floating point value according our rules, so we use double to store value of decimal in string.
use decimal2string?
Return values:

Reimplemented from Field_str.
