returns the value of current object (usually

<h3>Remarks</h3>
<P>If the value of current object is <STRONG

method returns NULL. Use <FONT
color=mediumblue face=""><A href="ValueRead_isNull.html" >SAValueRead::isNull</A></FONT> method to make
sure if the value is NULL or not.</P>
<P>If the value's type of current object is

<P> If the value's
type of current object is any data type except
<STRONG>SA_dtCursor</STRONG>, the
result is undefined and debug version asserts.</P>
<P>Use <A href="ValueRead_DataType.html" >SAValueRead::DataType</A> method to get the
