 Description   

If ENUM in procedure analyse() contains more than 58 characters, it is truncated:

Testcase:

create table t1 (v varchar(128));
 
insert into t1 values ('1111111111111111111111111111111111111111111111111111111112345');
 
select * from t1 procedure analyse();
 
drop table t1;

Expected result:

Field_name	Min_value	Max_value	Min_length	Max_length	Empties_or_zeros	Nulls	Avg_value_or_avg_length	Std	Optimal_fieldtype
 
test.t1.v	1111111111111111111111111111111111111111111111111111111112345	1111111111111111111111111111111111111111111111111111111112345	61	61	0	0	61.0000	NULL	ENUM('1111111111111111111111111111111111111111111111111111111112345') NOT NULL

Actual result:

Field_name	Min_value	Max_value	Min_length	Max_length	Empties_or_zeros	Nulls	Avg_value_or_avg_length	Std	Optimal_fieldtype
 
test.t1.v	1111111111111111111111111111111111111111111111111111111112345	1111111111111111111111111111111111111111111111111111111112345	61	61	0	0	61.0000	NULL	ENUM('1111111111111111111111111111111111111111111111111111111112
