Dapper

Dapper, a light weight object mapper for ADO.NET

Purge the query cache

Return a count of all the cached queries by dapper

Return a list of all the queries cached by dapper

Deep diagnostics only: find any hash collisions in the cache

Configire the specified type to be mapped to a given db-type

Execute parameterized SQL

Number of rows affected

Return a list of dynamic objects, reader is closed after the call

Executes a query, returning the data typed as per T

the dynamic param may seem a bit odd, but this works around a major usability issue in vs, if it is Object vs completion gets annoying. Eg type new [space] get new object A sequence of data of the supplied type; if a basic type (int, string, etc) is queried then the data from the first column in assumed, otherwise an instance is created per row, and a direct column-name===member-name mapping is assumed (case insensitive).

Execute a command that returns multiple result sets, and access each in turn

Return a typed list of objects, reader is closed after the call

Maps a query to objects

The first type in the recordset The second type in the recordset The return type The Field we should split and read the second object from (default: id) Number of seconds before command execution timeout Is it a stored proc or a batch?

Maps a query to objects

The Field we should split and read the second object from (default: id) Number of seconds before command execution timeout

Perform a multi mapping query with 4 input parameters

Perform a multi mapping query with 5 input parameters

Perform a multi mapping query with 6 input parameters

Perform a multi mapping query with 7 input parameters

Internal use only

Gets type-map for the given type

Type map implementation, DefaultTypeMap instance if no override present

Set custom mapping for type deserializers

Entity type to override Mapping rules impementation, null to remove custom map

Internal use only

Throws a data exception, only used internally

Execute a query asynchronously using .NET 4.5 Task.

Maps a query to objects

The Field we should split and read the second object from (default: id) Number of seconds before command execution timeout

Perform a multi mapping query with 4 input parameters

Perform a multi mapping query with 5 input parameters

Perform a multi mapping query with 6 input parameters

Perform a multi mapping query with 7 input parameters

Called if the query cache is purged via PurgeQueryCache

How should connection strings be compared for equivalence? Defaults to StringComparer.Ordinal. Providing a custom implementation can be useful for allowing multi-tenancy databases with identical schema to share startegies. Note that usual equivalence rules apply: any equivalent connection strings MUST yield the same hash-code.

Implement this interface to pass an arbitrary db specific set of parameters to Dapper

Add all the parameters needed to the command just before it executes

The raw command prior to execution Information about the query

Implement this interface to pass an arbitrary db specific parameter to Dapper

Add the parameter needed to the command before it executes

The raw command prior to execution Parameter name

Implement this interface to change default mapping of reader columns to type memebers

Finds best constructor

DataReader column names DataReader column types Matching constructor or default one

Gets mapping for constructor parameter

Constructor to resolve DataReader column name Mapping implementation

Gets member mapping for column

DataReader column name Mapping implementation

Implements this interface to provide custom member mapping

Source DataReader column name

Target member type

Target property

Target field

Target constructor parameter

This is a micro-cache; suitable when the number of terms is controllable (a few hundred, for example), and strictly append-only; you cannot change existing values. All key matches are on **REFERENCE** equality. The type is fully thread-safe.

Identity of a cached query in Dapper, used for extensability

Create an identity for use with DynamicParameters, internal use only

The sql

The command type

Compare 2 Identity objects

The grid reader provides interfaces for reading multiple result sets from a Dapper query

Read the next grid of results, returned as a dynamic object

Read the next grid of results

Read multiple objects from a single recordset on the grid

Read multiple objects from a single record set on the grid

Dispose the grid, closing and disposing both the underlying reader and command.

A bag of parameters that can be passed to the Dapper Query and Execute methods

construct a dynamic parameter bag

can be an anonymous type or a DynamicParameters bag

Append a whole object full of params to the dynamic EG: AddDynamicParams(new {A = 1, B = 2}) // will add property A and B to the dynamic

Add a parameter to this dynamic parameter list

Add all the parameters needed to the command just before it executes

The raw command prior to execution Information about the query

Get the value of a parameter

The value, note DBNull.Value is not returned, instead the value is returned as null

All the names of the param in the bag, use Get to yank them out

This class represents a SQL string, it can be used if you need to denote your parameter is a Char vs VarChar vs nVarChar vs nChar

Create a new DbString

Add the parameter to the command... internal use only

Ansi vs Unicode

Fixed length

Length of the string -1 for max

The value of the string

Handles variances in features per DBMS

Dictionary of supported features index by connection type name

Gets the featureset based on the passed connection

True if the db supports array columns e.g. Postgresql

Represents simple memeber map for one of target parameter or property or field to source DataReader column

Creates instance for simple property mapping

DataReader column name Target property

Creates instance for simple field mapping

DataReader column name Target property

Creates instance for simple constructor parameter mapping

DataReader column name Target constructor parameter

DataReader column name

Target member type

Target property

Represents default type mapping strategy used by Dapper

Creates default type map

Entity type

Finds best constructor

DataReader column names DataReader column types Matching constructor or default one

Gets mapping for constructor parameter

Constructor to resolve DataReader column name Mapping implementation

Gets member mapping for column

DataReader column name Mapping implementation

Implements custom property mapping by user provided criteria (usually presence of some custom attribute with column to member mapping)

Creates custom property mapping

Target entity type Property selector based on target type and DataReader column name

Always returns default constructor

DataReader column names DataReader column types Default constructor

Not impelmeneted as far as default constructor used for all cases

Returns property based on selector strategy

DataReader column name Poperty member map
