public java.sql.ResultSet getVersionColumns(java.lang.String catalog,
java.lang.String schema,
java.lang.String table)
catalog
A String that contains the catalog name.
schema
A String that contains the schema name pattern.
table
A String that contains the table name.
A SQLServerResultSet object.
This getVersionColumns method is specified by the getVersionColumns method in the java.sql.DatabaseMetaData interface.
The result set returned by the getVersionColumns method will contain the following information:
| Name | Type | Description |
|---|---|---|
| SCOPE | short | Not supported by the JDBC driver. |
| COLUMN_NAME | String | The column name. |
| DATA_TYPE | short | The SQL data type from java.sql.Types. |
| TYPE_NAME | String | The name of the data type. |
| COLUMN_SIZE | int | The precision of the column. |
| BUFFER_LENGTH | int | The length of the column in bytes. |
| DECIMAL_DIGITS | short | The scale of the column. |
| PSEUDO_COLUMN | short | Indicates if the column is a pseudo column. It can be one of the following values: versionColumnUnknown (0) versionColumnNotPseudo (1) versionColumnPseudo (2) |
Note
For more information about the data returned by the getVersionColumns method, see "sp_datatype_info (Transact-SQL)" in [!INCLUDEssNoVersion] Books Online.
The following example demonstrates how to use the getVersionColumns method to return information about the columns that are automatically updated in the Person.Contact table in the [!INCLUDEssSampleDBnormal] sample database.
public static void executeGetVersionColumns(Connection con) {
try {
DatabaseMetaData dbmd = con.getMetaData();
ResultSet rs = dbmd.getVersionColumns("AdventureWorks", "Person", "Contact");
ResultSetMetaData rsmd = rs.getMetaData();
// Display the result set data.
int cols = rsmd.getColumnCount();
while(rs.next()) {
for (int i = 1; i <= cols; i++) {
System.out.println(rs.getString(i));
}
}
rs.close();
}
catch (Exception e) {
e.printStackTrace();
}
}
