toloop through all the rows in the table<br /> and in each iteration I need to fetch the value of mydate in to a
variable<br/> and split it to month and year and add two rows with *value, 91, month* (2 ,<br /> 91, Augest) and
*value,86, year* (2 , 86 , 2009)<br /><br /> So I need an idea on<br /> - how to loop through all the rows thats
returnedby a select statement.<br /> - for each statement how to get the value of mydate in to a variable, so<br />
thatI can use SubString to split it in to date and year and use them in the<br /> insert statement.<br

substring()below:<div class="Ih2E3d"><br /><br /> INSERT INTO metadata (value, field, mydate)<br /></div> SELECT
value,91,substring(mydate, '(.+) ')<br /> FROM metadata<br /> UNION ALL<br /> SELECT value, 86, substring(mydate, '
(.+)')<br/> FROM metadata;<br /><br /> Does that do it for you? Try the SELECT clauses by themselves to check if
they'redoing the right thing.<br /><font color="#888888"><br /> -- <br />  Richard Huxton<br />  Archonet Ltd<br
