------------------------------------------------------------------
Here's the culprit, a private function that converts a scala value to a SQL
literal. Note use of {{toString}} to format dates and timestamps. Seems like
there should be some hook to a {{JDBCDialect}} that can handle vendor-specific
syntax etc.
{code:lang=java}
/**
* Converts value to SQL expression.
*/
private def compileValue(value: Any): Any = value match {
case stringValue: String => s"'${escapeSql(stringValue)}'"
case timestampValue: Timestamp => "'" + timestampValue + "'"
case dateValue: Date => "'" + dateValue + "'"
case arrayValue: Array[Any] => arrayValue.map(compileValue).mkString(", ")
case _ => value
}
{code}
