When a literalcharacter string appears where a date value is expected, the Oracle Lite databasetests the string to see if it matches the formats of Oracle, SQL-92, or the valuespecified for this parameter in the POLITE.INI file. Setting this parameter alsodefines the default format used in the TO_CHAR or TO_DATE functions when noother format string is supplied.For Oracle the default is dd-mon-yy or dd-mon-yyyy, and for SQL-92 the default isyy-mm-dd or yyyy-mm-dd.Using 'RR' in the format forces two-digit years less than or equal to 49 to beinterpreted as years in the 21st century (2000-2049), and years over 50 as years inthe 20th century (1950-1999). Setting the RR format as the default for all two-digityear 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 descriptorfunction 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 quotesvar $concat_operator='||';var $sysDate = "TRUNC(SYSDATE)";var $sysTimeStamp = 'SYSDATE'; // requires oracle 9 or later, otherwise use SYSDATEvar $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-DDvar $metaTablesSQL = "select table_name,table_type from cat where table_type in ('TABLE','VIEW') and table_name not like 'BIN\$%'"; // bin$ tables are recycle bin tablesvar $metaColumnsSQL = "select cname,coltype,width, SCALE, PRECISION, NULLS, DEFAULTVAL from col where tname='%s' order by colno"; //changed by smondino@users.sourceforge. netvar $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_colswhere owner='%s' and table_name='%s' order by column_id"; // when there is a schemavar $_bindInputArray = true;var $hasGenID = true;var $_genIDSQL = "SELECT (%s.nextval) FROM DUAL";var $_genSeqSQL = "DECLAREPRAGMA AUTONOMOUS_TRANSACTION;BEGINexecute 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 = array();var $_nestedSQL = true;var $_getarray = false; // currently not workingvar $leftOuter = ''; // oracle wierdness, $col = $value (+) for LEFT OUTER, $col (+)= $value for RIGHT OUTERvar $session_sharing_force_blob = false; // alter session on updateblob if set to truevar $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 formatvar $useDBDateFormatForTextInput=false;var $datetime = false; // MetaType('DATE') returns 'D' (datetime==false) or 'T' (datetime == true)var $_refLOBs = array();// var $ansiOuter = true; // if oracle9/** Legacy compatibility for sequence names for emulated auto-increments*/public $useCompactAutoIncrements = false;/** Defines the schema name for emulated auto-increment columns*/public $schema = false;/** Defines the prefix for emulated auto-increment columns*/public $seqPrefix = 'SEQ_';/* function MetaColumns($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.
