* 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 REPLACE query just updates its values instead of
* 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.
* @param string $table name of the table on which the REPLACE query will
* @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 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.
* this property is required unless the Null property
* Name of the type of the field. Currently, all types Metabase
* are supported except for clob and blob.
* Default: no type conversion
* Boolean property that indicates that the value for this field
* 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.
* 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.
* @return integer the number of affected rows
