    <p>VBScript, PowerShell, or C# (I use CS-Script to run my C# scripts) would be <em>much</em> cleaner - but sometimes I enjoy a little batch file challenge.</p> <p>So - this is for 1 month from the current date and time, but it gives you the idea. To actually figure 30 days, I suspect you'd need about 50 lines of IF statements. Or, a single external EXE to calculate it for you.</p> <p>I think there's a cleaner way to use SET itself to split out the date parts, which would cut this down by about 3 lines - but I don't recall the syntax ATM.</p> <pre><code>Batch1 ECHO %DATE% &gt; start.txt Batch2 : Get start date FOR /F "tokens=1* delims= " %%i IN (start.txt) DO set startDate=%%j FOR /F "tokens=1,2 eol=/ delims=/ " %%i IN ('echo %startDate%') DO set startMonth=%%i FOR /F "tokens=1,2 delims=/ eol=/" %%i IN ('echo %startDate%') DO set startDay=%%j FOR /F "tokens=2,3 delims=/ " %%i IN ('echo %startDate%') DO set startYear=%%j : Get run month and day as YYYY-MM-DD SET /A runMonth=%startMonth% + 1 IF %runMonth% LEQ 10 SET runMonth=0%runMonth% SET runDay=%startDay% SET runYear=%startYear% SET runDate=%runYear%-%runMonth%-%runDay% : Get current month and day as YYYY-MM-DD FOR /F "tokens=1* delims= " %%i IN ('echo %DATE%') DO set nowDate=%%j FOR /F "tokens=1,2 eol=/ delims=/ " %%i IN ('echo %nowDate%') DO set nowMonth=%%i FOR /F "tokens=1,2 delims=/ eol=/" %%i IN ('echo %nowDate%') DO set nowDay=%%j FOR /F "tokens=2,3 delims=/ " %%i IN ('echo %nowDate%') DO set nowYear=%%j SET nowDate=%nowYear%-%nowMonth%-%nowDay% : Compare IF %nowDate% GEQ %runDate% ECHO Delete! </code></pre> <p>Note that this doesn't handle year changes appropriately (it'll delete on the year change).</p>

    1. COwhen I run batch1 the date is MM\DD\YYYY.But when I run batch2 the startdate is DD and the startmonth is also DD.The final equation is if rundate==nowdate execute command,it should be rundate=>nowdate,cause if pc not switched on rundate.secondly months with 31days the rundate would 31st next month

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
