Associates a PHP variable with a column for query fetches using oci_fetch().
The oci_define_by_name() call must occur before executing oci_execute().
A valid OCI8 statement identifier created by oci_parse() and executed by oci_execute(), or a REF CURSOR statement identifier.
The column name used in the query.
Use uppercase for Oracle's default, non-case sensitive column names. Use the exact column name case for case-sensitive column names.
The PHP variable that will contain the returned column value.
The data type to be returned. Generally not needed. Note that Oracle-style data conversions are not performed. For example, SQLT_INT will be ignored and the returned data type will still be SQLT_CHR.
You can optionally use oci_new_descriptor() to allocate LOB/ROWID/BFILE descriptors.
Returns TRUE
on success or FALSE
on failure.
