|

|

|
| | | * Associative array with the names of the fields to be changed as indexes
|

|
| | | * array with the properties of the fields to that are meant to be changed as

| | | * array entries. These entries should be assigned to the new values of the
|
| | | * respective properties. The properties of the fields should be the same
|
| | | * as defined by the MDB2 parser.

| | | * 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. |
| | | * |
