All rights 00004 reserved. 00005 Released under both BSD license and Lesser GPL library license. 00006 Whenever there is any discrepancy between the two licenses, 00007 the BSD license will take precedence. 00008 Set tabs to 4 for best viewing. 00009 00010 Latest version is available at http://adodb.sourceforge.net 00011 00012 21.02.2002 - Wade Johnson wade@wadejohnson.de 00013 Extended ODBC class for Sybase SQLAnywhere. 00014 1) Added support to retrieve the last row insert ID on tables with 00015 primary key column using autoincrement function. 00016 00017 2) Added blob support. Usage: 00018 a) create blob variable on db server: 00019 00020 $dbconn->create_blobvar($blobVarName); 00021 00022 b) load blob var from file. $filename must be complete path 00023 00024 $dbcon->load_blobvar_from_file($blobVarName, $filename); 00025 00026 c) Use the $blobVarName in SQL insert or update statement in the values 00027 clause: 00028 00029 $recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) ' 00030 . 00031 'VALUES (\'test\', ' . $blobVarName . ')'); 00032 00033 instead of loading blob from a file, you can also load from 00034 an unformatted (raw) blob variable: 00035 $dbcon->load_blobvar_from_var($blobVarName, $varName); 00036 00037 d) drop blob variable on db server to free up resources: 00038 $dbconn->drop_blobvar($blobVarName); 00039 00040 Sybase_SQLAnywhere data driver.
