interface RowSetMetaData : ResultSetMetaData
An object that contains information about the columns in a RowSet object. This interface is an extension of the ResultSetMetaData interface with methods for setting the values in a RowSetMetaData object. When a RowSetReader object reads data into a RowSet object, it creates a RowSetMetaData object and initializes it using the methods in the RowSetMetaData interface. Then the reader passes the RowSetMetaData object to the rowset.
The methods in this interface are invoked internally when an application calls the method RowSet.execute; an application programmer would not use them directly.

From class ResultSetMetaData
String! |
getCatalogName(column: Int)
Gets the designated column's table's catalog name.
|
String! |
getColumnClassName(column: Int)
Returns the fully-qualified name of the Java class whose instances are manufactured if the method ResultSet.getObject is called to retrieve a value from the column. ResultSet.getObject may return a subclass of the class returned by this method.
|
Int |
getColumnCount()
Returns the number of columns in this ResultSet object.
|
Int |
getColumnDisplaySize(column: Int)
Indicates the designated column's normal maximum width in characters.
|
String! |
getColumnLabel(column: Int)
Gets the designated column's suggested title for use in printouts and displays. The suggested title is usually specified by the SQL AS clause. If a SQL AS is not specified, the value returned from getColumnLabel will be the same as the value returned by the getColumnName method.
|
String! |
getColumnName(column: Int)
Get the designated column's name.
|
Int |
getColumnType(column: Int)
Retrieves the designated column's SQL type.
|
String! |
getColumnTypeName(column: Int)
Retrieves the designated column's database-specific type name.
|
Int |
getPrecision(column: Int)
Get the designated column's specified column size. For numeric data, this is the maximum precision. For character data, this is the length in characters. For datetime datatypes, this is the length in characters of the String representation (assuming the maximum allowed precision of the fractional seconds component). For binary data, this is the length in bytes. For the ROWID datatype, this is the length in bytes. 0 is returned for data types where the column size is not applicable.
|
Int |
getScale(column: Int)
Gets the designated column's number of digits to right of the decimal point. 0 is returned for data types where the scale is not applicable.
|
String! |
getSchemaName(column: Int)
Get the designated column's table's schema.
|
String! |
getTableName(column: Int)
Gets the designated column's table name.
|
Boolean |
isAutoIncrement(column: Int)
Indicates whether the designated column is automatically numbered.
|
Boolean |
isCaseSensitive(column: Int)
Indicates whether a column's case matters.
|
Boolean |
isCurrency(column: Int)
Indicates whether the designated column is a cash value.
|
Boolean |
isDefinitelyWritable(column: Int)
Indicates whether a write on the designated column will definitely succeed.
|
Int |
isNullable(column: Int)
Indicates the nullability of values in the designated column.
|
Boolean |
isReadOnly(column: Int)
Indicates whether the designated column is definitely not writable.
|
Boolean |
isSearchable(column: Int)
Indicates whether the designated column can be used in a where clause.
|
Boolean |
isSigned(column: Int)
Indicates whether values in the designated column are signed numbers.
|
Boolean |
isWritable(column: Int)
Indicates whether it is possible for a write on the designated column to succeed.
|
|
From class Wrapper
Boolean |
isWrapperFor(iface: Class<*>!)
Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling isWrapperFor on the wrapped object. If this does not implement the interface and is not a wrapper, return false. This method should be implemented as a low-cost operation compared to unwrap so that callers can use this method to avoid expensive unwrap calls that may fail. If this method returns true then calling unwrap with the same argument should succeed.
|
T |
unwrap(iface: Class<T>!)
Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy. If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling unwrap recursively on the wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface, then an SQLException is thrown.
