12 21.02.2002 - Wade Johnson wade@wadejohnson.de
13 Extended ODBC class for Sybase SQLAnywhere.
14 1) Added support to retrieve the last row insert ID on tables with
15 primary key column using autoincrement function.
16
17 2) Added blob support. Usage:
18 a) create blob variable on db server:
19
20 $dbconn->create_blobvar($blobVarName);
21
22 b) load blob var from file. $filename must be complete path
23
24 $dbcon->load_blobvar_from_file($blobVarName, $filename);
25
26 c) Use the $blobVarName in SQL insert or update statement in the values
27 clause:
28
29 $recordSet = $dbconn->Execute('INSERT INTO tabname (idcol, blobcol) '
30 .
31 'VALUES (\'test\', ' . $blobVarName . ')');
32
33 instead of loading blob from a file, you can also load from
34 an unformatted (raw) blob variable:
35 $dbcon->load_blobvar_from_var($blobVarName, $varName);
36
37 d) drop blob variable on db server to free up resources:
38 $dbconn->drop_blobvar($blobVarName);
39
40 Sybase_SQLAnywhere data driver. Requires ODBC.
