    Interface DataTypeMap

    Maps data types from one database platform to another. Each dialect provides its own DataTypeMap implementation.

    interface DataTypeMap {
        MapType(
            sourceType: string,
            sourceLength?: number,
            sourcePrecision?: number,
            sourceScale?: number,
        ): MappedType;
        MapTypeToString(
            sourceType: string,
            sourceLength?: number,
            sourcePrecision?: number,
            sourceScale?: number,
        ): string;
    }
