The Table Metadata node extracts metadata for a specified table. This information can be used to identify changes in the corresponding physical table. The properties dialog for this node includes the following elements:
Name - Specifies a name for the node.
Notes - Enables you to open the Notes dialog. You use the dialog to enter optional details or any other relevant information for the input.
Input Table - Enables you to select a database and table from which you are retrieving table metadata. Click Browse to navigate to a table.
The following table displays the metadata information that can be extracted from a selected input table:
| Property | Description |
|---|---|
| BUFFER_LENGTH | Size in bytes required to store the data. |
| CHAR_OCTET_LENGTH | Maximum length in bytes of a character or binary data type field. |

| NULLABLE | Displays whether the field allows nulls to be entered. |
| NUM_PREC_RADIX | For numeric data, this will be either 10 or 2. If 10, then COLUMN_SIZE and DECIMAL_DIGITS give the number of digits for the field. If 2, then these two give the number of bits allowed for the field (base 2). |
