Question

您好我收到一个非常奇怪的错误：ORA-01861：文字与格式字符串不匹配。我的所有互联网搜索都与DATE问题有关。我只是为了保存一个简单的字符串。如果您发现问题，请告诉我如何解决问题。

问题列

TREND: VARCHAR2(31, CHAR), no constraints

通过以下方式在GORM中映射：

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

问题方法：

    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都是趋势向上，趋向于向下或趋势稳定。

Answer 1

我解决了自己的问题。

表中有一个Date字段被错误地表示为Domain类中的String。即使我尝试更新VARCHAR2字段，domain_class.save（）方法也会更新该domain_class的每个属性 - 因此错误与TREND字段无关，但与错误的DATE字段无关。

我通过添加到DataSource.groovy

来解决这个问题

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EVERY属性。

希望这有助于将来。
