visual studio 2010 - How to generate model from database using Dapper?

Question

I am coming from PetaPoco camp. PetaPoco has a T4 template which generates model from the database. Is anything similar available for Dapper?

I installed Dapper using NuGet and added SqlHelper.cs, but I didn't find anything which generates model from the database.

I've just recently written a sql query to do the job for myself. And updating it with extra types when i need. Just replace the table name where it says @@@@.

To make alot of tables i created a temp stored procedure to call. eg. exec createTablePOCO(@tableName)

SELECT 
    'public ' + a1.NewType + ' ' + a1.COLUMN_NAME + ' {get;set;}'
    ,*
FROM (
    /*using top because i'm putting an order by ordinal_position on it. 
    putting a top on it is the only way for a subquery to be ordered*/
    SELECT TOP 100 PERCENT
    COLUMN_NAME,
    DATA_TYPE,
    IS_NULLABLE,
    CASE 
        WHEN DATA_TYPE = 'varchar' THEN 'string'
        WHEN DATA_TYPE = 'datetime' AND IS_NULLABLE = 'NO' THEN 'DateTime'
        WHEN DATA_TYPE = 'datetime' AND IS_NULLABLE = 'YES' THEN 'DateTime?'
        WHEN DATA_TYPE = 'int' AND IS_NULLABLE = 'YES' THEN 'int?'
        WHEN DATA_TYPE = 'int' AND IS_NULLABLE = 'NO' THEN 'int'
        WHEN DATA_TYPE = 'smallint' AND IS_NULLABLE = 'NO' THEN 'Int16'
        WHEN DATA_TYPE = 'smallint' AND IS_NULLABLE = 'YES' THEN 'Int16?'
        WHEN DATA_TYPE = 'decimal' AND IS_NULLABLE = 'NO' THEN 'decimal'
        WHEN DATA_TYPE = 'decimal' AND IS_NULLABLE = 'YES' THEN 'decimal?'
        WHEN DATA_TYPE = 'numeric' AND IS_NULLABLE = 'NO' THEN 'decimal'
        WHEN DATA_TYPE = 'numeric' AND IS_NULLABLE = 'YES' THEN 'decimal?'
        WHEN DATA_TYPE = 'money' AND IS_NULLABLE = 'NO' THEN 'decimal'
        WHEN DATA_TYPE = 'money' AND IS_NULLABLE = 'YES' THEN 'decimal?'
        WHEN DATA_TYPE = 'bigint' AND IS_NULLABLE = 'NO' THEN 'long'
        WHEN DATA_TYPE = 'bigint' AND IS_NULLABLE = 'YES' THEN 'long?'
        WHEN DATA_TYPE = 'tinyint' AND IS_NULLABLE = 'NO' THEN 'byte'
        WHEN DATA_TYPE = 'tinyint' AND IS_NULLABLE = 'YES' THEN 'byte?'
        WHEN DATA_TYPE = 'char' THEN 'string'
        WHEN DATA_TYPE = 'timestamp' THEN 'byte[]'
        WHEN DATA_TYPE = 'varbinary' THEN 'byte[]'
        WHEN DATA_TYPE = 'bit' AND IS_NULLABLE = 'NO' THEN 'bool'
        WHEN DATA_TYPE = 'bit' AND IS_NULLABLE = 'YES' THEN 'bool?'
        WHEN DATA_TYPE = 'xml' THEN 'string'
    END AS NewType
    FROM INFORMATION_SCHEMA.COLUMNS 
    WHERE TABLE_NAME = '@@@@'
    ORDER BY ORDINAL_POSITION
) as a1
