我正在使用 ibatis 和 java webapp 插入一行。 POJO 有一个字段需要存储一个数字(比如 3.0 或 2.34)。我试过在 Java 端使用 BigDecimal 和 Double。在 MySQL 端,我使用的是 Decimal(5, 5) 数据类型。
当我尝试插入一个以“4”作为该数字字段值的行时,MySQL 和 iBatis 抛出以下异常:
org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation: encountered SQLException [
--- The error occurred in org/mySQL.xml.
--- The error occurred while applying a result map.
--- Check the mySQL.insertQuery.
--- The error happened while setting a property on the result object.
--- Cause: java.lang.RuntimeException: org.springframework.jdbc.UncategorizedSQLException: SqlMapClient operation: encountered SQLException [

我是否为要插入的值使用了错误的 java 数据类型?如果不是,为什么 MySQL 不让我插入值?
最佳答案
您似乎误解了如何在 SQL 中定义 DECIMAL
(或可能的 NUMERIC
)列 -
具体来说,当将列定义为 DECIMAL(x, y)
时,x
是该列将存储的总位数, >y
是小数点后 的位数。因此,在您的列定义中,您指定了 -1 < column < 1 的范围。数据类型是正确的,但您正试图指定列被告知允许的范围之外的值。
幸运的是,修复很简单:更改列定义。我假设您希望在小数点前 有最多 5 位数字,这将使列定义 DECIMAL(10, 5)
。
