How to convert custom string to Date in SQL Server

Question

How to convert yyyyMMddhh (2017092018) string to Date in SQL Server 2012?

Is it possible to do without using T-SQL to put the sentence into the INSERT clause?

INSERT INTO [dbo].[Table](SomeColumn) 
VALUES (CONVERT(DATETIME, '2017092018', 'yyyyMMddhh'));

Answer 1

Example

Declare @S varchar(50)='2017092018'

Select convert(datetime,left(@S,8)) + convert(datetime,right(@S,2)+':00')

Returns

2017-09-20 18:00:00.000

If 2012+, I would suggest try_convert() just in case you have some unexpected values.
