The SQL below makes sense. However it is extremely slow. Am I right in thinking that a join (MySQL) could be used and that the code could dispense with the embedded Perl?
my $sql_count_A_Ref_vs_Comp = "
SELECT '".$Reference."', '".$Comparitor."', A.entity_name FROM e_ann
+otation_090812.annotation A
WHERE A.user IN (
SELECT T.Line FROM e_annotation_090812.Temp_table T
)
AND A.entity_name IN (
SELECT B.entity_name from e_annotation_090812.annotation B
WHERE B.user IN (
SELECT U.Line FROM e_annotation_090812.Temp_table U
)
AND B.entity_name LIKE '_%' AND B.evidence_code NOT LIKE
+'%_________8__' AND B.centre LIKE '".$Reference."'
)
AND A.entity_name LIKE '_%' AND A.evidence_code NOT LIKE '%______
+___8__' AND A.centre LIKE '".$Comparitor."'
";

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
