GORM（varchar.save（），非日期）：ORA-01861:文本与格式字符串不匹配

您好，我收到一个非常奇怪的错误：ORA-01861:文本与格式字符串不匹配。我所有的网络搜索都与日期问题有关。我的只是保存一个简单的字符串。如果您看到问题，请让我知道如何解决它

专栏

TREND: VARCHAR2(31, CHAR), no constraints

在GORM中映射为：

String trend
...
static constraints = {
    trend(nullable: true, blank: true)
... } ...
static mapping = {
    trend column: "TREND", sqlType: "varchar(31)"
...}

发行方式：

    def fix_trend(){
    // There should ever only be three values found in the trend column
    //  of the Reports table: "TRENDING UP", "TRENDING STEADY", "TRENDING DOWN"
    println "Running groovy database procedure : fix_trend"
    StatusReport.list().each{
        String trend = it.trend
        if (trend != 'TRENDING UP' && trend != 'TRENDING STEADY' && trend != 'TRENDING DOWN'){
            trend = trend?.toUpperCase()
            if (trend == null){
                trend = 'TRENDING STEADY'
            }
            else if (trend.contains('UP')){
                trend = 'TRENDING UP';
            }
            else if (trend.contains('DOWN')){
                trend = 'TRENDING DOWN';
            }
            else{
                trend = 'TRENDING STEADY';
            }
            it.trend = trend;
            it.save();
        }
    }
    println "fix_trend completed"
}

该方法的目的是确保所有值要么呈上升趋势，要么呈下降趋势，要么呈稳定趋势

我解决了自己的问题

表中有一个日期字段在域类中被错误地表示为字符串。即使我试图更新一个VARCHAR2字段，domain_class.save（）方法也会更新该domain_类的每个属性——因此错误与趋势字段无关，而是与误报的日期字段相关

我通过添加DataSource.groovy解决了这个问题

logSql = true
formatSql = true

和Config.groovy

log4j.main = {
trace 'org.hibernate.type'
debug 'org.hibernate.SQL'
...

这表明.save（）生成的update语句尝试更新每个属性

希望这对将来的人有所帮助。

请确保用于插入值的编码由数据库防御使用。我的数据库的NLS_字符集属性为“AL32UTF8”。这是编码错误吗？
