DETAIL: A field with precision 12, scale 2 must round to an absolute value less than 10^10. As the result shows, the system displays anumeric field overflowerror message, in addition to details explaining what happened. So, when a situation like this occurs, the system doesn’t insert the...
In Transact-SQL statements, a constant with a decimal point is automatically converted into anumeric data value, using the minimum precision and scale necessary. For example, the constant 12.345 is converted into anumeric value with a precision of 5 and a scale of 3. 四,将小数转换成字符串(v...

可以使用等值的十进制整数或者b'value'的形式给二进制字段赋值,BIT类型会将整数转化为二进制数来存储。如果存储时数据位数小于字段指定位数则前面会补0。 通常使用BIT(1)来指定是否删除字段,实际上使用BIT(1)和使用TINYINT占用的存储空间都是1个字节,使用BIT(1)的好处是可以限定是否删除字段必须是0或1,所以还是建...
在Transact-SQL 语句中,小数数值的常量自动转换为 decimal 数据类型,在转换时,使用最小的精度和小数位数。例如,常量 12.345 被转换为numeric值,其精度为 5,小数位为 3。 In Transact-SQL statements, a constant with a decimal point is automatically converted into anumeric data value, using the minimum prec...
I have an application written in EF 4 that works with an existing MS-SQL database - this is NOT code first development. The tables in the SQL database have dozens of fields defined as Decimal with a Scale value of 2 or 4. When the Entity Data Model was created, the fields in t...
my_isspace(&my_charset_latin1, *end)) { err = E_DEC_TRUNCATED; break; } } check_result_and_overflow(mask, err, decimal_value); return err; } str2my_decimal 函数先将数值字符串转为合适的字符集后,调用 string2decimal 函数将数值字符串转为 decimal_t 类型的数据。my_decimal 类型和 ...
For FLOAT, the SQL standard permits an optional specification of the precision (but not the range of the exponent) in bits following the keywordFLOAT in parentheses. MySQL also supports this optional precision specification, but the precision value is used only to determine storage size. A precisi...
