Hi All,

How do I convert a text data type column to datetime?
The query below returns this error: Explicit conversion from data type text to datetime is not allowed.

SELECT CONVERT(DATETIME, vchValue) FROM dtlConfiguration WHERE vchParameter = 'LastRTADImport'

The data in 'vchValue' column is in this format: 'Jul 21 2010 10:15AM'

Regards
Teee

Convert to VARCHAR then convert to datetime.

CONVERT(DATETIME,CONVERT(VARCHAR,vchValue))

The following link details what can and cannot be converted

Are you sure that is causing the problem?
This should work

select convert(datetime, 'Jul 21 2010 10:15AM')

Could be due to your settings maybe.

Cursors never.
DTS - only when needed and never to control.

The question and topic title say they are converting from TEXT to DATETIME, you cannot convert TEXT directly to DATETIME, you have to do an implicit conversion to VARCHAR then to DATETIME
