-    /**
-     * Execute a SQL REPLACE query. A REPLACE query is identical to a INSERT
-     * query, except that if there is already a row in the table with the same
-     * key field values, the old row is deleted before the new row is inserted.
-     *
-     * The REPLACE type of query does not make part of the SQL standards. Since
-     * practically only MySQL implements it natively, this type of query is
-     * emulated through this method for other DBMS using standard types of
-     * queries inside a transaction to assure the atomicity of the operation.
-     *
-     * @access public
-     *
-     * @param string $table name of the table on which the REPLACE query will
-     *  be executed.
-     * @param array $fields associative array that describes the fields and the
-     *  values that will be inserted or updated in the specified table. The
-     *  indexes of the array are the names of all the fields of the table. The
-     *  values of the array are also associative arrays that describe the
-     *  values and other properties of the table fields.
-     *
-     *  Here follows a list of field properties that need to be specified:
-     *
-     *    value:
-     *          Value to be assigned to the specified field. This value may be
-     *          of specified in database independent type format as this
-     *          function can perform the necessary datatype conversions.
-     *
-     *    Default:
-     *          this property is required unless the Null property
-     *          is set to 1.
-     *
-     *    type
-     *          Name of the type of the field. Currently, all types Metabase
-     *          are supported except for clob and blob.
-     *
-     *    Default: no type conversion
-     *
-     *    null
-     *          Boolean property that indicates that the value for this field
-     *          should be set to null.
-     *
-     *          The default value for fields missing in INSERT queries may be
-     *          specified the definition of a table. Often, the default value
-     *          is already null, but since the REPLACE may be emulated using
-     *          an UPDATE query, make sure that all fields of the table are
-     *          listed in this function argument array.
-     *
-     *    Default: 0
-     *
-     *    key
-     *          Boolean property that indicates that this field should be
-     *          handled as a primary key or at least as part of the compound
-     *          unique index of the table that will determine the row that will
-     *          updated if it exists or inserted a new row otherwise.
-     *
-     *          This function will fail if no key field is specified or if the
-     *          value of a key field is set to null because fields that are
-     *          part of unique index they may not be null.
-     *
-     *    Default: 0
-     *

+     *          of specified in database independent type format as this

+     *          function can perform the necessary datatype conversions.

+     *

+     *    Default:

+     *          this property is required unless the Null property

+     *          is set to 1.

+     *

+     *    type

+     *          Name of the type of the field. Currently, all types Metabase

+     *

+     *          The default value for fields missing in INSERT queries may be

+     *          specified the definition of a table. Often, the default value

+     *          is already null, but since the REPLACE may be emulated using

+     *          an UPDATE query, make sure that all fields of the table are

+     *          listed in this function argument array.

+     *
