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
(PHP 5, PHP 7, PHP 8, PECL OCI8 >= 1.1.0)
oci_result — Returns field's value from the fetched row
Returns the data from column in the current row,
fetched by oci_fetch().

statement
columnCan be either use the column number (1-based) or the column name. The case of the column name must be the case that Oracle meta data describes the column as, which is uppercase for columns created case insensitively.
Returns everything as strings except for abstract types (ROWIDs, LOBs and
FILEs). Returns false on error.

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 outNote 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");
...

Regards,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 1FYI--
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)

Jimif 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;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.I am trying to get a list of the first character of a character string.

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 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.
