**SETNULLS** sets the NULL state of every column in the table based on the contents of the passed string. The passed string must be obtained from a prior call to GETNULLS. This function is valid on all SQL table types.

**Errors Posted:**

| 75 | Invalid Column Type Descriptor ' Indicating that the passed string was too small. |
| 80 | Function Not Supported |

**Example:**

**StorageString STRING(255)**

**Rec           STRING(2048)**

**  CODE**

**  StorageString = GETNULLS(table)  !Get NULL state of table**

**  Rec = table.record               !Save record buffer**

**  ! Do Table Processing**

**  Table.Record = Rec               !Restore record buffer**
