(PHP 5, PECL OCI8 >= 1.1.0)

oci_field_precisionTell the precision of a field

Beschreibung

int oci_field_precision ( resource $statement , int $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).

Parameter-Liste

statement

A valid OCI statement identifier.

field

Can be the field's index (1-based) or name.

Rückgabewerte

Returns the precision as an integer, or FALSE on errors.

Anmerkungen

Hinweis:

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.

I did not test well before posting previous code.  This if statement works and the other does not.

if( ocicolumnscale($R, $i ) != 129 )
{
    $int_decimal = ocicolumnscale($R, $i );
    $int_length = ocicolumnprecision($R, $i) - $int_decimal;
}

I've found that when using ocicolumnprecision or oci_field_precision it will not show you the decimal places if you are are reading from tables with decimals.  You can use ocicolumnscale or oci_field_scale to find the decimal.

if( ocicolumnscale($R, $i ) > 0 )
{
    $int_decimal = ocicolumnscale($R, $i );
    $int_length = ocicolumnprecision($R, $i) - $int_decimal;
}
