getObject Method (int) (SQLServerResultSet)

  • Cikk

Download JDBC driver

Gets the value of the designated column index in the current row of this SQLServerResultSet object as an object in the Java programming language.

Syntax

  
public java.lang.Object getObject(int columnIndex)

Parameters

columnIndex

An int that indicates the column index.

Return Value

An Object value.

Exceptions

SQLServerException

Remarks

This getObject method is specified by the getObject method in the java.sql.ResultSet interface.

This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the SQL type of the column, following the mapping for built-in types that is specified in the JDBC specification. If the value is a SQL NULL, the driver returns a Java null.

This method can also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of the getObject method is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).

Beginning in the SQL Server JDBC Driver 3.0:

  • A value of type date will be returned as a java.sql.Date object.

  • A value of type time will be returned as a java.sql.Time object.

  • A value of type datetime2 will be returned as a java.sql.Timestamp object.

  • A value of type datetimeoffset will be returned as a microsoft.sql.DateTimeOffset object.
