Interface Array

public abstract interface Array

JDBC 2.0

The mapping in the Java programming language for the SQL type ARRAY. By default, an Array is a transaction duration reference to an SQL array. By default, an Array is implemented using an SQL LOCATOR(array) internally.

Method Detail

getBaseTypeName

public String getBaseTypeName()
                       throws SQLException

Returns the SQL type name of the elements in the array designated by this Array object. If the elements are a built-in type, it returns the database-specific type name of the elements. If the elements are a user-defined type (UDT), this method returns the fully-qualified SQL type name.

Returns:

a String that is the database-specific name for a built-in base type or the fully-qualified SQL type name for a base type that is a UDT

Throws:

SQLException - if an error occurs while attempting to access the type name

getBaseType

public int getBaseType()
                throws SQLException

Returns the JDBC type of the elements in the array designated by this Array object.

Returns:

a constant from the class Types that is the type code for the elements in the array designated by this Array object.

Throws:

SQLException - if an error occurs while attempting to access the base type

getArray

public Object getArray()
                throws SQLException

Retrieves the contents of the SQL array designated by this Array object in the form of an array in the Java programming language. This version of the method getArray uses the type map associated with the connection for customizations of the type mappings.

Returns:

an array in the Java programming language that contains the ordered elements of the SQL ARRAY object designated by this object

Throws:

SQLException - if an error occurs while attempting to access the array

getArray

public Object getArray(Map map)
                throws SQLException

Retrieves the contents of the SQL array designated by this Array object, using the specified map for type map customizations. If the base type of the array does not match a user-defined type in map, the standard mapping is used instead.

Parameters:

map - a java.util.Map object that contains mappings of SQL type names to classes in the Java programming language

Returns:

an array in the Java programming language that contains the ordered elements of the SQL array designated by this object

Throws:

SQLException - if an error occurs while attempting to access the array

getArray

public Object getArray(long index,
                       int count)
                throws SQLException

Returns an array containing a slice of the SQL array, beginning with the specified index and containing up to count successive elements of the SQL array. This method uses the type-map associated with the connection for customizations of the type-mappings.

Parameters:

index - the array index of the first element to retrieve; the first element is at index 1

count - the number of successive SQL array elements to retrieve

Returns:

an array containing up to count consecutive elements of the SQL array, beginning with element index

Throws:

SQLException - if an error occurs while attempting to access the array

getArray

public Object getArray(long index,
                       int count,
                       Map map)
                throws SQLException

Returns an array containing a slice of the SQL array object designated by this object, beginning with the specified index and containing up to count successive elements of the SQL array. This method uses the specified map for type-map customizations unless the base type of the array does not match a user- defined type in map, in which case it uses the standard mapping.

Parameters:

index - the array index of the first element to retrieve; the first element is at index 1

count - the number of successive SQL array elements to retrieve

map - a java.util.Map object that contains SQL type names and the classes in the Java programming language to which they are mapped

Returns:

an array containing up to count consecutive elements of the SQL array designated by this Array object, beginning with element index.

Throws:

SQLException - if an error occurs while attempting to access the array

getResultSet

public ResultSet getResultSet()
                       throws SQLException

Returns a result set that contains the elements of the array designated by this Array object. If appropriate, the elements of the array are mapped using the connection's type map; otherwise, the standard mapping is used.

The result set contains one row for each array element, with two columns in each row. The second column stores the element value; the first column stores the index into the array for that element (with the first array element being at index 1). The rows are in ascending order corresponding to the order of the indices.

Returns:

a ResultSet object containing one row for each of the elements in the array designated by this Array object, with the rows in ascending order based on the indices.

Throws:

SQLException - if an error occurs while attempting to access the array

getResultSet

public ResultSet getResultSet(Map map)
                       throws SQLException

Returns a result set that contains the elements of the array designated by this Array object and uses the given map to map the array elements. If the base type of the array does not match a user-defined type in map, the standard mapping is used instead.

The result set contains one row for each array element, with two columns in each row. The second column stores the element value; the first column stores the index into the array for that element (with the first array element being at index 1). The rows are in ascending order corresponding to the order of the indices.

Parameters:

map - contains mapping of SQL user-defined types to classes in the Java(tm) programming language

Returns:

a ResultSet object containing one row for each of the elements in the array designated by this Array object, with the rows in ascending order based on the indices.

Throws:

SQLException - if an error occurs while attempting to access the array

getResultSet

public ResultSet getResultSet(long index,
                              int count)
                       throws SQLException

Returns a result set holding the elements of the subarray that starts at index index and contains up to count successive elements. This method uses the connection's type map to map the elements of the array if the map contains an entry for the base type. Otherwise, the standard mapping is used.

The result set has one row for each element of the SQL array designated by this object, with the first row containing the element at index index. The result set has up to count rows in ascending order based on the indices. Each row has two columns: The second column stores the element value; the first column stroes the index into the array for that element.

Parameters:

index - the array index of the first element to retrieve; the first element is at index 1

count - the number of successive SQL array elements to retrieve

Returns:

a ResultSet object containing up to count consecutive elements of the SQL array designated by this Array object, starting at index index.

Throws:

SQLException - if an error occurs while attempting to access the array

getResultSet

public ResultSet getResultSet(long index,
                              int count,
                              Map map)
                       throws SQLException

Returns a result set holding the elements of the subarray that starts at index index and contains up to count successive elements. This method uses the Map object map to map the elements of the array unless the base type of the array does not match a user-defined type in map, in which case it uses the standard mapping.

The result set has one row for each element of the SQL array designated by this object, with the first row containing the element at index index. The result set has up to count rows in ascending order based on the indices. Each row has two columns: The second column stores the element value; the first column stroes the index into the array for that element.

Parameters:

index - the array index of the first element to retrieve; the first element is at index 1

count - the number of successive SQL array elements to retrieve

map - the Map object that contains the mapping of SQL type names to classes in the Java(tm) programming language

Returns:

a ResultSet object containing up to count consecutive elements of the SQL array designated by this Array object, starting at index index.

Throws:

SQLException - if an error occurs while attempting to access the array
