Hello,
Using Postgresql version 7.1 and having a problem with data being inserted
into 2 tables when it should only be going into 1.
1st I created several new tables using a template.
# create the new table
my $SQL = "CREATE TABLE \"$newtable\" () inherits
(\"template2\") ";
my $stmt_handle = $dbh->prepare($SQL);
my $rows = $stmt_handle->execute;
$stmt_handle->finish();
But when I insert data into a table, it also gets added into another table.
my $SQL="INSERT INTO \"$series\" ( \"PrintOrder\", \"Description\",
\"FullText\",
\"Obsolete\", \"Author\", \"Comments\", \"Limits\",
\"AuditRequired\",
\"Selections\", \"SelectionList\", \"RadioOption\",
\"CheckOption\", \"Locked\")
VALUES ( '$printorder', '$description', '$fulltext',
'$obsolete',
'$author', '$comments', '$limits', '$audit', '$selections',
'$selectionlist',
'$radio', '$check', '$locked')";
my $stmt_handle=$dbh->prepare($SQL);
my $rows=$stmt_handle->execute;
$stmt_handle->finish();
This results in the data being added to the correct table, but also to
another table:
For example. If I add a line to the table "workmanship", the line also
appears in the table "acpower".
If I then delete the line from "workmanship" it is also gone from "acpower"
If I run: EXPLAIN SELECT "PrintOrder" from "acpower"; I get:
NOTICE: QUERY PLAN
Result (cost-0.00..3.27 rows=28 width=12)
-> Append (cost=0.00..3.27 rows=28 width=12)
-> Seq Scan on acpower (cost=0.00..1.13 rows=13 width=12)
-> Seq Scan on template2 acpower (cost=0.00..0.00 rows=1 width=12)
-> Seq Scan on General Requirements acpower (cost=0.00..1.11
rows=11 width=12)
-> Seq Scan on workmanship acpower (cost0.00..1.03 rows=3
width=12)
It appears to me that it is linking these tables together and whenever I do
something to one, it is mirrored in the others. Can find nothing that
explains this operation or how to disconnect the tables from each other.
Table structures are:
