When a literal character string appears where a date value is expected, the Oracle Lite database tests the string to see if it matches the formats of Oracle, SQL-92, or the value specified for this parameter in the POLITE.INI file. Setting this parameter also defines the default format used in the TO_CHAR or TO_DATE functions when no other format string is supplied. For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default is yy-mm-dd or yyyy-mm-dd. Using 'RR' in the format forces two-digit years less than or equal to 49 to be interpreted as years in the 21st century (2000-2049), and years over 50 as years in the 20th century (1950-1999). Setting the RR format as the default for all two-digit year entries allows you to become year-2000 compliant. For example: NLS_DATE_FORMAT='RR-MM-DD' You can also modify the date format using the ALTER SESSION command. */ # define the LOB descriptor type for the given type # returns false if no LOB descriptor function oci_lob_desc($type) { switch ($type) { case OCI_B_BFILE: return OCI_D_FILE; case OCI_B_CFILEE: return OCI_D_FILE; case OCI_B_CLOB: return OCI_D_LOB; case OCI_B_BLOB: return OCI_D_LOB; case OCI_B_ROWID: return OCI_D_ROWID; } return false; } class ADODB_oci8 extends ADOConnection { var $databaseType = 'oci8'; var $dataProvider = 'oci8'; var $replaceQuote = "''"; // string to use to replace quotes var $concat_operator='||'; var $sysDate = "TRUNC(SYSDATE)"; var $sysTimeStamp = 'SYSDATE'; // requires oracle 9 or later, otherwise use SYSDATE var $metaDatabasesSQL = "SELECT USERNAME FROM ALL_USERS WHERE USERNAME NOT IN ('SYS','SYSTEM','DBSNMP','OUTLN') ORDER BY 1"; var $_stmt; var $_commit = OCI_COMMIT_ON_SUCCESS; var $_initdate = true; // init date to YYYY-MM-DD var $metaTablesSQL = "select table_name,table_type from cat where table_type in ('TABLE','VIEW') and table_name not like 'BIN\$%'"; // bin$ tables are recycle bin tables var $metaColumnsSQL = "select cname,coltype,width, SCALE, PRECISION, NULLS, DEFAULTVAL from col where tname='%s' order by colno"; //changed by smondino@users.sourceforge. net var $metaColumnsSQL2 = "select column_name,data_type,data_length, data_scale, data_precision, case when nullable = 'Y' then 'NULL' else 'NOT NULL' end as nulls, data_default from all_tab_cols where owner='%s' and table_name='%s' order by column_id"; // when there is a schema var $_bindInputArray = true; var $hasGenID = true; var $_genIDSQL = "SELECT (%s.nextval) FROM DUAL"; var $_genSeqSQL = " DECLARE PRAGMA AUTONOMOUS_TRANSACTION; BEGIN execute immediate 'CREATE SEQUENCE %s START WITH %s'; END; "; var $_dropSeqSQL = "DROP SEQUENCE %s"; var $hasAffectedRows = true; var $random = "abs(mod(DBMS_RANDOM.RANDOM,10000001)/10000000)"; var $noNullStrings = false; var $connectSID = false; var $_bind = false; var $_nestedSQL = true; var $_hasOciFetchStatement = false; var $_getarray = false; // currently not working var $leftOuter = ''; // oracle wierdness, $col = $value (+) for LEFT OUTER, $col (+)= $value for RIGHT OUTER var $session_sharing_force_blob = false; // alter session on updateblob if set to true var $firstrows = true; // enable first rows optimization on SelectLimit() var $selectOffsetAlg1 = 1000; // when to use 1st algorithm of selectlimit. var $NLS_DATE_FORMAT = 'YYYY-MM-DD'; // To include time, use 'RRRR-MM-DD HH24:MI:SS' var $dateformat = 'YYYY-MM-DD'; // DBDate format var $useDBDateFormatForTextInput=false; var $datetime = false; // MetaType('DATE') returns 'D' (datetime==false) or 'T' (datetime == true) var $_refLOBs = array(); // var $ansiOuter = true; // if oracle9 function __construct() { $this->_hasOciFetchStatement = ADODB_PHPVER >= 0x4200; if (defined('ADODB_EXTENSION')) { $this->rsPrefix .= 'ext_'; } } /* function MetaColumns($table, $normalize=true) added by smondino@users.sourceforge.net*/ function MetaColumns($table, $normalize=true) { global $ADODB_FETCH_MODE; $schema = ''; $this->_findschema($table, $schema); $save = $ADODB_FETCH_MODE; $ADODB_FETCH_MODE = ADODB_FETCH_NUM; if ($this->fetchMode !== false) { $savem = $this->SetFetchMode(false); } if ($schema){ $rs = $this->Execute(sprintf($this->metaColumnsSQL2, strtoupper($schema), strtoupper($table))); } else { $rs = $this->Execute(sprintf($this->metaColumnsSQL,strtoupper($table))); } if (isset($savem)) { $this->SetFetchMode($savem); } $ADODB_FETCH_MODE = $save; if (!$rs) { return false; } $retarr = array(); while (!$rs->EOF) { $fld = new ADOFieldObject(); $fld->name = $rs->fields[0]; $fld->type = $rs->fields[1]; $fld->max_length = $rs->fields[2]; $fld->scale = $rs->fields[3]; if ($rs->fields[1] == 'NUMBER') { if ($rs->fields[3] == 0) { $fld->type = 'INT'; } $fld->max_length = $rs->fields[4]; } $fld->not_null = (strncmp($rs->fields[5], 'NOT',3) === 0); $fld->binary = (strpos($fld->type,'BLOB') !== false); $fld->default_value = $rs->fields[6]; if ($ADODB_FETCH_MODE == ADODB_FETCH_NUM) { $retarr[] = $fld; } else { $retarr[strtoupper($fld->name)] = $fld; } $rs->MoveNext(); } $rs->Close(); if (empty($retarr)) { return false; } return $retarr; } function Time() { $rs = $this->Execute("select TO_CHAR($this->sysTimeStamp,'YYYY-MM-DD HH24:MI:SS') from dual"); if ($rs && !$rs->EOF) { return $this->UnixTimeStamp(reset($rs->fields)); } return false; } /** * Multiple modes of connection are supported: * * a.
