PHP Bug Type: PDO related
Bug description: bindValue does not use data_type parameter correctly
Description:
------------
The function odbc_stmt_param_hook() in pdo_odbc\odbc_stmt.c does not use
the data_type parameter correctly if the call to SQLDescribeParam()does not
succeed.
Instead of converting in this case the data_type parameter from
PDO:PARAM_* to the matching SQL type, it sets in most cases the SQL type to
SQL_LONGVARCHAR.
Remark: The data_type parameter should IMHO have absolute priority over
SQLDescribeParam(). In effect, if the data_type parameter is specified,
than there is no point in even calling SQLDescribeParam(). Especially since
the ODBC database server may not be able to assign a correct data-type to
the place-holder ('?').
Reproduce code:
---------------
gDBObject = new PDO('odbc:DATABASE', '', '');
$x = 1;
$lvStmt = $gDBObject->prepare('SELECT col1 FROM Table WHERE col2 = ?');
$lvStmt->bindValue(1,$x, PDO::PARAM_INT);
$lvStmt->execute();
But you do need to use an ODBC database that will not return in this case
a SQL_SUCCESS return-value for SQLDescribeParam() !
Expected result:
----------------
I would expect the following request to be sent to the ODBC database
server:
SELECT col1 FROM Table WHERE col2 = 1
Actual result:
--------------
The following request is sent to the ODBC database server:
SELECT col1 FROM Table WHERE col2 = '1'
which is a syntax error, since col2 is integer.
