<br>

<br>
<b>Example:</b>
<br>
<span style="font-family:Courier New; font-size:8pt; color:#000000">&nbsp;&nbsp;ABSDatabase1.DatabaseName&nbsp;:=&nbsp;<span style="font-family:Courier New; font-size:8pt; color:#000080">'emp_db'</span></span><span style="font-family:Courier New; font-size:8pt; color:#000000">;&nbsp;<span style="font-family:Courier New; font-size:8pt; color:#007F00">//&nbsp;unique&nbsp;name&nbsp;used&nbsp;further&nbsp;to&nbsp;identify&nbsp;db</span></span><span style="font-family:Courier New; font-size:8pt; color:#000000">
