'datetime2' error when using entity framework in VS 2010 .net 4.0

Question

Getting this error:

System.Data.SqlClient.SqlException : The conversion of a datetime2 data type to a datetime data type resulted in an out-of-range v

Answer 1

Use that SQL script to convert all the columns from datetime to datetime2. It skips all the tables contains 'aspnet' for your convenience.

DECLARE @SQL AS NVARCHAR(1024)
DECLARE @TBL AS NVARCHAR(255)
DECLARE @COL AS NVARCHAR(255)
DECLARE @NUL AS BIT

DECLARE CUR CURSOR FAST_FORWARD FOR
    SELECT  SCHEMA_NAME(t.schema_id)+'.'+t.name, c.name, c.is_nullable
    FROM    sys.tables AS t
    JOIN    sys.columns c ON t.object_id = c.object_id
    JOIN    information_schema.columns i ON i.TABLE_NAME = t.name 
                                        AND i.COLUMN_NAME = c.name
    WHERE   i.data_type = 'datetime' and t.name not like '%aspnet%'

    ORDER BY t.name, c.name

OPEN CUR
FETCH NEXT FROM CUR INTO @TBL, @COL, @NUL
WHILE @@FETCH_STATUS = 0
BEGIN
    SELECT @SQL = 'ALTER TABLE ' + @TBL 
        + ' ALTER COLUMN [' + @COL + '] datetime2' 
        + (CASE WHEN @NUL=1 THEN '' ELSE ' NOT' END) + ' NULL;'
    EXEC sp_executesql @SQL
    FETCH NEXT FROM CUR INTO @TBL, @COL, @NUL
END

CLOSE CUR;
DEALLOCATE CUR;

It works for me!
