# oci_field_precision

(PHP 5, PHP 7, PECL OCI8 >= 1.1.0)

oci_field_precision — Tell the precision of a field

### Description

oci_field_precision ( resource `$statement` , mixed `$field` ) : int

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).

### Parameters

`statement`

  A valid OCI statement identifier.

`field`

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

### Return Values

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

### Examples

Example #1 oci_field_precision() Example

`<?php
// Create the table with:
// CREATE TABLE mytab (c1 NUMBER, c2 FLOAT, c3 NUMBER(4), c4 NUMBER(5,3));
$conn = oci_connect("hr", "hrpwd", "localhost/XE");
if (!$conn) {
$m = oci_error();
trigger_error(htmlentities($m['message']), E_USER_ERROR);
}
$stid = oci_parse($conn, "SELECT * FROM mytab");
oci_execute($stid, OCI_DESCRIBE_ONLY); // Use OCI_DESCRIBE_ONLY if not fetching rows
$ncols = oci_num_fields($stid);
for ($i = 1; $i <= $ncols; $i++) {
echo oci_field_name($stid, $i) . " "
. oci_field_precision($stid, $i) . " "
. oci_field_scale($stid, $i) . "<br>\n";
}
// Outputs:
// C1 0 -127
// C2 126 -127
// C3 4 0
// C4 5 3
oci_free_statement($stid);
oci_close($conn);
?>`

### Notes

> 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.
