Storing decimal values inSQLdatabases is a common task. However, this requires careful consideration to ensure the data remains accurate and reliable. In this tutorial, we’ll explore how to store decimal values in SQL databases effectively. In addition, we’ll cover the available data types, ho...
in set (0.00 sec) mysql> insert into decimal_tb (col2) values (12.2300); Query OK, 1 row affected (0.01 sec) # 变量范围测试 # 结论:M范围是1到65,D范围是0到30,且D不大于M mysql> alter table decimal_tb add column col3 decimal(6,6); Query OK, 0 rows affected (0.12 sec) ...
AI代码解释 mysql>create tablef2(f1float(15,2));QueryOK,0rowsaffected(0.01sec)mysql>insert into f2values(123456789.39);QueryOK,1rowaffected(0.00sec)mysql>select*from f2;+---+|f1|+---+|123456792.00|+---+1rowinset(0.00sec) 最后你会发现,连整数都不准了,小数被完全抹去了。 第二个误区,对于...
We are seeing the same issue. EF appears to be truncating decimal values -- it shouldn't do anything, right? In our situation, the SQL column is defined as decimal(17, 3). If we try to store the value17.7025093307, EF will truncate the value to17.702prior to sending it to SQL. ...
标准SQL要求DECIMAL(5,2)能够存储五位数和两位小数的任何值,因此可以存储在薪水列中的值范围为-999.99至999.99。 在标准SQL中,语法DECIMAL(M)等效于DECIMAL(M,0)。类似地,语法DECIMAL等效于DECIMAL(M,0),M的默认值为10。 如果刻度为0,则DECIMAL值不包含小数点或小数部分。
CREATETABLEdecimal_table(idINTAUTO_INCREMENTPRIMARYKEY,valueDECIMAL(10,2));INSERTINTOdecimal_table(value)VALUES(10.5),(20.25),(15.75); 1. 2. 3. 4. 5. 6. 现在,我们可以使用SUM函数对value列进行求和操作: SELECTSUM(value)FROMdecimal_table; ...
可以用函数RIGHT(字段名，1)例如：mysql> create table DECIMALTEST(ID INT NOT NULL AUTO_INCREMENT,VAL DECIMAL PRIMARY KEY(ID))ENGINE=INNODB,DEFAULT CHARSET=UTF8;Query OK, 0 rows affected (0.28 sec)mysql> INSERT INTO DECIMALTEST (VAL) VALUES (111.3),(213.5);Query OK, 2 rows...
INSERTINTOfinancial_records(transaction_amount)VALUES(12345.67); 如果小数位数超过2位,此时将会进行四舍五入,最终只会保存2位小数,示例如下: mysql>INSERTINTOfinancial_records (transaction_amount)VALUES(12345.688); Query OK,1rowaffected,1warning (0.03sec) ...
insert into TestDecimal1 (col1) Values (1234.56)Arithmetic overflow error converting numeric to data type numeric. The statement has been terminated. But, if you have more digits in the fraction position, SQL Server rounds them off. For Example .456 is rounded off to .47 as the column allo...
在floating_point_values的表,其中包含了四个列,具体含义如下: small_float:用 FLOAT 类型来存储非常小的数值。 large_float:用 FLOAT 类型来存储非常大的数值。 small_double:用 DOUBLE 类型来存储非常小的数值。 large_double:用 DOUBLE 类型来存储非常大的数值。
