The precision and scale determine the maximum limit that you can store in decimal data type. The maximum number of digits to the right of the decimal point (the integer part) is equal to the precision minus scale (p-s). For Example in a Decimal(5,2) column the integer portion can con...

double *result; /* example for DOUBLE */ DECIMAL (p , s) 或 NUMERIC (p , s) 無效,因為沒有 C 語言表示法。 如果您想要傳遞十進位值,則必須將參數定義為可從 DECIMAL 強制轉型的資料類型 (例如 CHAR 或 DOUBLE) ,並明確地將引數強制轉型為此類型。 若為 DOUBLE ,您不需要將十進位引數明確強制轉...
CAST(expression AS data_type[(length)]) CAST()函数将任何类型的值转换为具有指定类型的值。目标类型可以是以下类型之一:BINARY,CHAR,DATE,DATETIME,TIME,DECIMAL,SIGNED,UNSIGNED。 CAST()函数通常用于返回具有指定类型的值,以便在WHERE,JOIN和HAVING子句中进行比较。
