OCI_FIELD_SCALE(3)														OCI_FIELD_SCALE(3)

oci_field_scale - Tell the scale of the field

SYNOPSIS

       int oci_field_scale (resource  $statement, mixed  $field)

DESCRIPTION

	Returns the scale of the column with $field index.

	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

	      o $statement
		- A valid OCI statement identifier.

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

RETURN VALUES

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

EXAMPLES

       Example #1

	      oci_field_scale(3) 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>
";
	      }

	      // 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  ocicolumnscale(3)  instead.  This name still can be used, it was left as alias of
	      oci_field_scale(3) for downwards compatability. This, however, is deprecated and not recommended.

oci_parse - Prepares an Oracle statement for execution

SYNOPSIS

       resource oci_parse (resource  $connection, string  $sql_text)

DESCRIPTION

	Prepares  $sql_text using $connection and returns the statement identifier, which can be used with oci_bind_by_name(3), oci_execute(3) and
       other functions.

	Statement identifiers can be freed with oci_free_statement(3) or by setting the variable to NULL.

PARAMETERS

	      o $connection
		- An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).

	      o $sql_text
		- The SQL or PL/SQL statement.	SQL statements should not end with a semi-colon (";"). PL/SQL statements should end with  a  semi-
		colon (";").

RETURN VALUES

	Returns a statement handle on success, or FALSE on error.

EXAMPLES

       Example #1

	      oci_parse(3) example for SQL statements

	      <?php

	      $conn = oci_connect('hr', 'welcome', 'localhost/XE');

	      // Parse the statement. Note there is no final semi-colon in the SQL statement
	      $stid = oci_parse($conn, 'SELECT * FROM employees');
	      oci_execute($stid);

	      echo "<table border='1'>
";
	      while ($row = oci_fetch_array($stid, OCI_ASSOC+OCI_RETURN_NULLS)) {
		  echo "<tr>
";
		  foreach ($row as $item) {
		      echo "	<td>" . ($item !== null ? htmlentities($item, ENT_QUOTES) : "&nbsp;") . "</td>
";
		  }
		  echo "</tr>
";
	      }
	      echo "</table>
";

	      ?>

       Example #2

	      oci_parse(3) example for PL/SQL statements

	      <?php

	      /*
		Before running the PHP program, create a stored procedure in
		SQL*Plus or SQL Developer:

		CREATE OR REPLACE PROCEDURE myproc(p1 IN NUMBER, p2 OUT NUMBER) AS
		BEGIN
		    p2 := p1 * 2;
		END;

	      */

	      $conn = oci_connect('hr', 'welcome', 'localhost/XE');
	      if (!$conn) {
		  $e = oci_error();
		  trigger_error(htmlentities($e['message'], ENT_QUOTES), E_USER_ERROR);
	      }

	      $p1 = 8;

	      // When parsing PL/SQL programs, there should be a final semi-colon in the string
	      $stid = oci_parse($conn, 'begin myproc(:p1, :p2); end;');
	      oci_bind_by_name($stid, ':p1', $p1);
	      oci_bind_by_name($stid, ':p2', $p2, 40);

	      oci_execute($stid);

	      print "$p2
";   // prints 16

	      oci_free_statement($stid);
	      oci_close($conn);

	      ?>

NOTES

       Note

	       This  function  does not validate $sql_text. The only way to find out if $sql_text is a valid SQL or PL/SQL statement is to execute
	      it.
