|
|
* inserting a new row.
|
|
*
|
|
* 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.

* 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

* 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
