hello experts,
I am new to BOIS and wrote below statement in the rule:
$aa = SQL('connection', 'SELECT count(*) FROM table 1 where field1 = \'$parameter0\''' ); $parameter0 is varchar
if ($aa > 0 )
return true;
else
return false;
....
The issue is if I use a constant instead of the parameter like (where field1 = \'1000\') the result is correct.
But if I use parameter like above, the result is always false.
Could you please let me know where is my fault. thank you in advance.
