I am trying to create a sql server computed column with an alter statement below,but I can't seem to get it working. Any help will be appreciated.
ALTER TABLE Schedule ADD
[SubmitDate] AS
IF(AND(REVIEWDueStatus=10 AND IsNull(ReviewDate_Actual ))
"<DIV>
<table><tr><td style='vertical-align:top;text-
align:left;'>Due:</td><td valign='top' align='left'> "&TEXT([ReviewDate],"dd mmm yyyy")&"</td>
</tr>
<tr><td style='vertical-align:top;text-
align:left;'>Act:</td><td valign='top'
align='left'>NR</td></tr></table></DIV>",
IF(ReviewDueStatus=10,"<DIV>
<table><tr><td style='vertical-align:top;text-align:left;'>Due:</td>
<td valign='top' align='left'> "&TEXT([ReviewDate],"dd mmm yyyy")&"</td>
</tr><tr><td style='vertical-align:top;text-
align:left;'>Act:</td><td valign='top' align='left'> "&TEXT([ReviewDate_Actual],"dd mmm yyyy")&"</td>
<td>NR</td></tr></table></DIV>", ""))

a calculated column cannot have an if statement; you canuse a CASE though

something like this is what i think you wnat:

SET QUOTED_IDENTIFIER ON

ALTER TABLE Schedule ADD

[SubmitDate] AS

CASE

WHEN REVIEWDueStatus=10 AND ReviewDate_Actual IS NOT NULL

THEN

'<DIV>

<table><tr><td style=''vertical-align:top;text-

align:left;''>Due:</td><td valign=''top'' align=''LEFT''> "&TEXT([ReviewDate],"dd mmm yyyy")&"</td>

</tr>

<tr><td style=''vertical-align:top;text-

align:left;''>Act:</td><td valign=''top''

align=''left''>NR</td></tr></table></DIV>'

WHEN ReviewDueStatus=10

THEN '<DIV>

<table><tr><td style=''vertical-align:top;text-align:left;''>Due:</td>

<td valign=''top'' align=''left''> "&TEXT([ReviewDate],"dd mmm yyyy")&"</td>

</tr><tr><td style=''vertical-align:top;text-

align:left;''>Act:</td><td valign=''top'' align=''left''> "&TEXT([ReviewDate_Actual],"dd mmm yyyy")&"</td>

<td>NR</td></tr></table></DIV>'

ELSE ''

END

I think that you would be better off creating a view to do this than creating a computed column. In a view, you will be able to use FOR XML to help construct your HTML, which will prevent the errors that I'm receiving when trying to parse your data as XML.
