Thread: PEAR Problem
Hi, It's me again. I have been able to solve most of the porting problems from mysql to pgsql. But I have got struck in one place. I have a problem where PEAR's associative array doesn't recognise the mix case letters. eg . I issue a query through PEAR db and get results using fetchRow of PEAR. Now I have set associative array feature ON. suppose the query is select NetCode,NetworkName from NetworkTab; this would return the result into a variable called $dbRow to echo the contents returned by the pgsql, I have to give $dbRow[NetCode] and $dbRow[NetworkName] This used to work perfectly fine with mysql, but as I moved to pgsql, PEAR started to return nothing like if i echo $dbRow[NetCode] it prints nothing but in the same echo is I change it echo $dbRow[netcode], it prints the value of the Network Code. How do I handle this situation. The application is fully written with Mix Case letters for the database fields and returned result set. And one more thing "SET AUTOCOMMIT=0" which is to set auto commiting to "No" in mysql doesn't work in pgsql what is the equivalent command. -- Best regards, Gurudutt mailto:guru@indvalley.com Life is not fair - get used to it.

Hi,
maybe this problem isn't originated in PEAR, but in pg itself.
Postgres folds everything to lowercase except one within "" (doublequotes).
So, if you - ie.: in psql:
psql=# CREATE TABLE veRYMixedCAse (NetCode integer,...);
then actually you will create a table named 'verymixedcase'.
In PHP (PEAR actually) you need to refer to this table and its columns
in lowercase.
You may run psql and execute:
\dt -- to figure out what names to be given to your tables
and then
\d NetworkTab or \d networktab -- and what names of the columns have

This is caused by the fact that PostgreSQL is case insensitive. In order for it to actually take the case into account, you need quote your field names and table names. So your query would then be: select "NetCode","NetworkName" from "NetworkTab"; Then you would be able to access the fields with $dbRow[NetworkName]. -Dan : Hi, : : It's me again.

Hello Dan,
Thanks very much for the help. Ya I tried enclosing with the quotes on
that unfortunately it doesn't work, it gives error.
Here are source code for the files.
You can try creating a table names ACT_NetworkTab with 2 fields,
NetCode(Integer) and NetWorkName(Varchar)
This is the php code which is used to print the values
<?
//include new pgsql pear db file ...
require_once("pgsqlpear.php");
//verify for database server ...
if(!$db)
{
//error occured .. send him to Error page ...
echo "Database conenction failed (Line : 18)";
exit;
}
else
{
//Begin Transaction ..
$Begin_Query = "BEGIN";
$Begin_Result = $db->query($Begin_Query);
//Auto Commit Query ..
//$AutoCommit_Query = "SET autocommit=0";
//$AutoCommit_Result = $db->query($AutoCommit_Query);
$Query = "SELECT \"NetCode\",\"NetWorkName\" FROM
\"ACT_NetworkTab\"";
$Result = $db->query($Query);
if(DB::isError($Result))
{
//Do a Roll Back ....
$RoleBack_Query = "ROLLBACK";
$RoleBack_Result = $db->query($RoleBack_Query);
echo "Query Failed (line 38)";
exit;
}
else
{
while($Row = $Result->fetchrow())
{
echo
"NetCode:",$Row[NetCode]."---NetName:".$Row[NetworkName];
echo "<br>";
}
} //end of if db success ....
//Commit the operation here .....
$Commit_Query = "COMMIT";
$Commit_Result = $db->query($Commit_Query);
} //end of if submit ...
?>
This is the pgsql.php include file for Database connectivity
<?
$dbuser = "postgres";
$dbpassword = "postgres";
$dbhost = "localhost";
$dbname = "ACTBilling";
require_once("DB.php");
$db = DB::connect("pgsql://$dbuser:$dbpassword@$dbhost/$dbname");
if(DB::isError($db))
{
$db = 0;
echo $db->getMessage();
}
else
{
$db->setFetchMode(DB_FETCHMODE_ASSOC);
}
?>
Please try and help me!!
