to_number的正确格式是:To_number(char,’format’)。其中char代表一个数值字符串,format代表char的格式。语句select to_number(0.25,'9.00') a from dual;中的0.25正确写法是'0.25',带有单引号。后边的格式'9.00'代表0.25的数值格式。9代表整数位数,0代表小数位数。如果写成0.99正好把格式倒过来了。当然会出错了...

SELECT TO_NUMBER('12345.6789', '99999.9999') AS converted_number FROM dual; 在这个示例中,字符串'12345.6789'被转换为数字12345.6789。由于我们在TO_NUMBER()函数中指定了格式模型'99999.9999',Oracle会尝试将字符串匹配到这个格式,并保留四位小数。因此,转换后的数字保留了原始字符串中的所有小数位。 然而,如果...
