(PHP 5, PECL oci8:1.1-1.2.4)
oci_field_precision — Tell the precision of a field
Returns precision of the field .
For FLOAT columns, precision is nonzero and scale is -127. If precision is 0, then column is NUMBER. Else it's NUMBER(precision, scale).
A valid OCI statement identifier.
Can be the field's index (1-based) or name.
Returns the precision as an integer, or FALSE on errors.
Note: In PHP versions before 5.0.0 you must use ocicolumnprecision() instead. This name still can be used, it was left as alias of oci_field_precision() for downwards compatability. This, however, is deprecated and not recommended.
