Types

class Contains(val target: Expression<*>, val candidate: Expression<*>, val path: String?, val jsonType: IColumnType<*>) : Op<Boolean> , ComplexExpression

Represents an SQL operator that checks whether a candidate expression is contained within a JSON target.

Exists

class Exists(val expression: Expression<*>, val path: String, val optional: String?, val jsonType: IColumnType<*>) : Op<Boolean> , ComplexExpression

Represents an SQL operator that checks whether data exists within a JSON expression at the specified path.

Extract

class Extract<T>(val expression: Expression<*>, val path: String, val toScalar: Boolean, val jsonType: IColumnType<*>, columnType: IColumnType<T & Any>) : Function<T>

Represents an SQL function that returns extracted data from a JSON object at the specified path, either as a JSON representation or as a scalar value.

JsonBColumnType

class JsonBColumnType<T : Any>(serialize: (T) -> String, deserialize: (String) -> T) : JsonColumnType<T>

Column for storing JSON data in binary format.

JsonColumnType

open class JsonColumnType<T : Any>(val serialize: (T) -> String, val deserialize: (String) -> T) : ColumnType<T> , JsonColumnMarker

Column for storing JSON data, either in non-binary text format or the vendor's default JSON type format.
