||
This function allows fiddling with the ODBC options for a
|
||
particular connection or query result. It was written to help
|
||
find work around to problems in quirky ODBC drivers. You should
|
||
probably only use this function if you are an ODBC programmer and
|
||
understand the effects the various options will have. You will
|
||
certainly need a good ODBC reference to explain all the different
|
||
options and values that can be used. Different driver versions
|
||
support different options.
|
||
</p>
|
||
<p class="para">
|
||
Because the effects may vary depending on the ODBC driver, use of
|
||
this function in scripts to be made publicly available is
|
||
strongly discouraged. Also, some ODBC options are not available
|
||
to this function because they must be set before the connection
|
||
is established or the query is prepared. However, if on a
|
||
particular job it can make PHP work so your boss doesn't tell you
|
||
to use a commercial product, that's all that really
|
||
matters.
