of this ResultSet object as an Object
in the Java programming language.

abstract member GetObject : string * System.Collections.Generic.IDictionary<string, Java.Lang.Class> -> Java.Lang.ObjectParameters
- columnLabel
- String
the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
- map
- IDictionary<String,Class>
a java.util.Map object that contains the mapping
from SQL type names to classes in the Java programming language
Returns
an Object representing the SQL value in the
specified column
- Attributes
Remarks
Retrieves the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language. If the value is an SQL NULL, the driver returns a Java null. This method uses the specified Map object for custom mapping if appropriate.

Remarks
Retrieves the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language. If the value is an SQL NULL, the driver returns a Java null. This method uses the given Map object for the custom mapping of the SQL structured or distinct type that is being retrieved.

of this ResultSet object as
an Object in the Java programming language.

Returns
a java.lang.Object holding the column value

Remarks
Gets the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language.
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 column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL, the driver returns a Java null.
This method may also be used to read database-specific abstract data types.
In the JDBC 2.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types.
If Connection.getTypeMap does not throw a SQLFeatureNotSupportedException, then 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()).
If Connection.getTypeMap does throw a SQLFeatureNotSupportedException, then structured values are not supported, and distinct values are mapped to the default Java class as determined by the underlying SQL type of the DISTINCT type.
