char(10) == char(10 byte) 指定为字符时,char(10 char) = 20B,(java中char是2B,c中char是1B) 一个英文字符占用1B 一个中文字符 GBK:2B,utf-8:2-4B 1、char(n)定长字符类型,n表示字节数,最大长度2000B。 2、varchar2(n)变长字符类型,n表示字节数。最大长度是4000B。 3、long变长字符类型,存...
Next, if we try to insert a negative value into the TINYINT UNSIGNED column ("col2"), it will result in an error because UNSIGNED values cannot be negative −INSERT INTO tinyint_table VALUES (127, -120, 128); The error message displayed is as follows −...
(Note that this program correctly forces BOOLEAN to TINYINT(1) when the table is saved. Step 2: --- a) Reverse Engineer table into Workbench. b) Edit table and change type of field `testbool` to BOOLEAN c) Synchronize the table. Note that the field is flagged as different. d) Repea...
When set to true, TINYINT(1) values are returned as booleans. Setting this to false causes TINYINT(1) to be returned as sbyte/byte. So I guess Pomelo needs to get back an sbyte/byte and can't handle a bool? Exactly the same experience. Setting it to false just doesn't make sense...
not store -255 to 255, only -128 to 127. You will have to use a smallint for -255 to ...
