Returns true if the bind succeeds, otherwise false. Details
|

about the error can be retrieved using the

This function binds the named PHP variable with a SQL parameter.
|
||
|
|
The SQL parameter must be in the form ":name". With the optional
|
||
|
|
type parameter, you can define whether the SQL parameter is an
|
||
|
|
in/out (0, default), in (1) or out (2) parameter. As of PHP
|
||
|
|
3.0.1, you can use the constants ORA_BIND_INOUT, ORA_BIND_IN and
|
||
|
|
ORA_BIND_OUT instead of the numbers.
|
||
|
|
|
||
|
|
<para>
|
||
|
|
ora_bind must be called after <function>ora_parse</function> and
|
||
|
|
before <function>ora_exec</function>. Input values can be given
|
||
|
|
by assignment to the bound PHP variables, after calling
|
||
|
|
<function>ora_exec</function> the bound PHP variables contain the output
|
||
|
|
values if available.
