Error when inserting record into mysql table

Question

I have created the following table:

CREATE TABLE IF NOT EXISTS `prices_1d` (
  `symbol` char(50) NOT NULL,
  `open_time` datetime DEFAULT NULL,
  `open` decimal(15,8) unsigned DEFAULT NULL,
  `high` decimal(15,8) unsigned DEFAULT NULL,
  `low` decimal(15,8) unsigned DEFAULT NULL,
  `close` decimal(15,8) unsigned DEFAULT NULL,
  `volume` decimal(15,8) DEFAULT NULL,
  `close_time` datetime DEFAULT NULL,
  `quote_av` decimal(15,8) DEFAULT NULL,
  `trades` bigint DEFAULT NULL,
  `tb_base_av` decimal(15,8) DEFAULT NULL,
  `tb_quote_av` decimal(15,8) DEFAULT NULL,
  PRIMARY KEY (`symbol`),
  KEY `symbol` (`symbol`),
  CONSTRAINT `FK__symbols` FOREIGN KEY (`symbol`) REFERENCES `symbols` (`symbol`) ON UPDATE RESTRICT
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

which is keyed based on another symbols column.

When I want to insert a single record into this prices_1d table using the following query:

INSERT INTO prices_1d (symbol,
                                open, 
                                high, 
                                low, 
                                close, 
                                volume, 
                                close_time, 
                                quote_av,
                                trades, 
                                tb_base_av, 
                                tb_quote_av, 
                                open_time) 
                    VALUES

                                open_time='2020-12-01 00:00:00'

I get the following error:

SQL Error (1264): Out of range value for column 'quote_av' at row 1

I don't understand while it fails for 'quote_av' as even changing the structure of the column from decimal(15,8) to decimal(30,10) doesn't change anything.

I thought it would be a matter of column order but I read on other posts that the order of the values inserted should not matter.

Answer 1

You quote_av is decimal(15,8)

So the following value will be out of range (more than 15 in total digits)

2446070334.82879867

For this case, you will need the quote_av structure to be

decimal(18,8)

but if you insert other "longer" values (higher precision), you will need to further increase the x and y in decima(x,y)
