    copied!<p>I have this query that is running error-free:</p> <pre><code>Select [Object], CASE WHEN MsgID = '61' THEN SUBSTRING(Parms,35,6) END AS [MEDIA] from JnlDataSection WHERE [Object] = '061 STATEMENTS' </code></pre> <p>There is a third column which I am interested in this table called Date. However database was developed a long time ago and the person that did has made date into a <code>(numeric(17,9), not null</code> datatype). E.g. <code>20130106.050257023</code>. </p> <p>What I want is this split into two different columns one as date: <code>2013-01-06</code> and the second as time: <code>05:02:57</code> (no microseconds). </p> <p>I have come up with this query to convert:</p> <pre><code>Select [Object], CAST(DATEADD(HOUR,-4,CONVERT(DATETIME,LEFT([Date],8)+' '+ SUBSTRING([Date],10,2)+':'+ SUBSTRING([Date],12,2)+':'+ SUBSTRING([Date],14,2)+'.'+ SUBSTRING([Date],15,3))) AS DATE) 'Date', LEFT(CAST(DATEADD(HOUR,-4,CONVERT(DATETIME,LEFT([Date],8)+' '+ SUBSTRING([Date],10,2)+':'+ SUBSTRING([Date],12,2)+':'+ SUBSTRING([Date],14,2)+'.'+ SUBSTRING([Date],15,3))) AS TIME),8) 'Time', CASE WHEN MsgID = '61' THEN SUBSTRING(Parms,35,6) END AS [MEDIA] from JnlDataSection WHERE [Object] = '061 STATEMENTS' AND CAST(substring(convert(varchar(50), [Date]), 0, 5) + '-' + substring(convert(varchar(50), [Date]), 5, 2) + '-' + substring(convert(varchar(50), [Date]), 7, 2) AS DATETIME) = CONVERT(date, DATEADD(day, -1, getdate())) --Converting </code></pre> <p>However I receive this error when I run this:</p> <blockquote> <p>Msg 8116, Level 16, State 1, Line 1<br> Argument data type numeric is invalid for argument 1 of substring function.</p> </blockquote> <p>Can anyone modify my query for it to run error free? That would be greatly appreciated.</p>
