oci_pconnect
I am trying to get a list of the first character of a character string.
SELECT distinct substr(version,1,1) as COL1 FROM SPHVVERS where Version is not null order by 1
This was working and then failed recently. I think it is because some of the strings now added contain a number as the first character.
I found to get it to work I had to use decode statement. (To_Char did not work )
SELECT distinct decode (substr(version,1,1),'1','?','0','!',substr(version,1,1)) as COL1 FROM SPHVVERS where Version is not null order by 1
oci_result
(PHP 5, PECL OCI8 >= 1.1.0)
oci_result — Devuelve el valor de un campo de un fila obtenida
Descripción
Devuelve los datos del campo dado por field de la fila actual,
obtenida mediante oci_fetch().
Para más detalles sobre cómo la extensión OCI8 realiza la correspondencia entre tipos de datos, véasen los tipos de datos admitidos por el controlador
Parámetros
-
statement -
-
field -
Puede ser el número de columna (basado en 1) o el nombre de columna (en mayúsculas).
Valores devueltos
Devuelve todo como una cadena excepto para tipos abstractos (ROWID, LOB y
FILE). Devuelve FALSE en caso de error.
Notas
Nota:
En versiones de PHP anteriores a la 5.0.0 se debe usar ociresult() en su lugar. Este nombre aún puede usarse; se dejó como alias de oci_result() por razones de retrocompatibilidad. Sin embargo, este nombre es obsoleto y no se recomienda.

if you want to join two tables having both the same column (e.g. 'id') but you don't want to (or cannot) specify all the other fields in these two tables (like erabbott mentioned), you can use:
SELECT t1.*, t2.*, t1.id AS id1, t2.id AS id2
FROM table1 t1, table2 t2;
Note that this does _not_ work:
SELECT *,t1.id AS id1, t2.id AS id2
FROM table1 t1, table2 t2;

FYI--
In order to modify Oracle dates (using NLS_DATE_FORMAT...), you must set $ORACLE_HOME first. This environmental variable is best set in the server startup script (i.e., ./apachectl)

As in my previous post, the same thing applies when using conversion functions in CLOB columns.
Probably the same thing will occur to any conversion function that you use.
So, this wont work
SELECT ... TO_CHAR(MY_CLOB) ...
$my_clob = OCIResult($stmt,"MY_CLOB");
But this will:
SELECT ... TO_CHAR(MY_CLOB) AS MYC ...
$my_clob = OCIResult($stmt,"MYC");
Best regards.

Note that if you are making multiple table selects, you must specify an alias to each column.
This wont work:
----------------------------------------
$qry = "SELECT A.COL_ONE, B.COL_ONE FROM TABLE1 A, TABLE2 B";
$stmt = OCIParse($conn, $qry);
while(OCIFetch($stmt))
{
$a = OCIResult($stmt, "A.COL_ONE");
...
----------------------------------------
But this will:
----------------------------------------
$qry = "SELECT A.COL_ONE AS X, B.COL_ONE AS Y FROM TABLE1 A, TABLE2 B";
$stmt = OCIParse($conn, $qry);
while(OCIFetch($stmt))
{
$a = OCIResult($stmt, "X");
...
----------------------------------------

I complained that I couldn't get the time from an Oracle date field. Joe Brown said:
This is not a PHP bug.
Consider setting NLS_DATE_FORMAT.
The manual states OCIResult() returns everything as a string.
NLS_DATE_FORMAT may not be appropriate for your needs.
There are quite a few places you can set NLS_DATE_FORMAT.
* Environment variables (or windows registry on win32)
* orclSID.ora
* on a per session basis; execute this statement after logon:
$cursor=OCIParse($connection,
"ALTER SESSION SET NLS_DATE_FORMAT='YYYY-MM-DD HH24:MI:SS'");
OCIExecute($cursor);
OCIFreeCursor($cursor);

As this function gets a 'mixed' variable type for the column index, you may use an integer to represent the column number. In this case, the count is starting from 1 and not from zero.
I am not sure, but I think this method is a bit faster than using the column name.
For an example, see the OCINumCols first example.

OCIResult() requires the column name to be written in capitals, so OCIResult($stmt,"column") won't work, but OCIResult($stmt,"COLUMN") works fine. Hope that helps somebody out

On the column names needing to be all caps. Just a guess.
Oracle is case sensitive when columns are created with quotes around them. When they are created without quotes around them, they are case insensitive. However, Oracle will always display them as being all caps.
If PHP referes to a column, it probably gets the case from Oracle. Then since PHP is case sensitive, you have ot supply it in all caps.
