abstract class Column<T>
A column in a select statement. This can be either a TableColumn or a QueryColumn.
<init> |
A column in a select statement. This can be either a TableColumn or a QueryColumn. Column(sqlName: String, adapter: ValueAdapter<T>, jsonName: String) |
adapter |
This column's Kotlin type, and a converter between that and JDBC's type system. val adapter: ValueAdapter<T> |
jsonName |
The name of this column when JSON-friendly maps are used. A reasonable default is provided if client code doesn't explicitly set a JSON name. See SelectQuery.setFromJson, ColumnSetter.setFromJson and ResultsHolder.getJson. val jsonName: String |
qualifiedName |
The name of this column, qualified by the table name if there is one. Gives a value like "MyTable.myColumn". open val qualifiedName: String |
sqlName |
The SQL name of this column, like "myColumn", or "COUNT(*)". val sqlName: String |
toString |
open fun toString(): String |
QueryColumn |
A query column with a SQL expression, like "COUNT(*)". QueryColumn values are read-only, and query columns cannot appear in a SelectQuery marked as for update. class QueryColumn<T> : Column<T> |
TableColumn |
A column in a Table. The SQL type of the column is determined by sqlType, and the Kotlin type is determined by adapter. See Table class TableColumn<T> : Column<T> |
