Фрагмент инструкции
java.sql.DriverManager.getConnection(String url,
User name and password arguments are ignored. All
String usr, String password)
connections have the same security privileges as the user
java.sql.DriverManager.getConnection(String url,
who invoked the Java VM.
Properties info)
javax.sql.DataSource.getConnection(String username,
String password)
java.sql.DriverManager.setLoginTImeout(...)
Login time-out is ignored.
javax.sql.DataSource.setLoginTimeout(...)
javax.sql.DataSource.setLogWriter
This method has no effect unless the JDBC trace facility
is enabled; for information on the JDBC trace facility, see
the NonStop Server for Java Programmer's Reference.
java.sql.Connection.createStatement(...)
The JDBC Driver for SQL/MX does not support the
java.sql.Connection.prepareStatement(...)
scroll-sensitive result set type, so an SQLWarning is
issued if an application requests that type. The result set is
changed to a scroll-insensitive type.
java.sql.Connection.setReadOnly(...)
The read-only attribute is ignored.
java.sql.ResultSetMetaData.getPrecision(int column)
For CLOB and BLOB columns, these methods return 0 to
java.sql.ResultSetMetaData.getColumnDisplaySize(int
denote an unlimited value. According to the standard API,
column)
the getPrecision() method and
getColumnDisplatSize() method return an integer
value, but LOB data larger than the maximum integer
value can be stored in the database.
java.sql.ResultSet.setFetchDirection(...)
The fetch direction attribute is ignored.
java.sql.Statement.setEscapeProcessing(...)
Because SQL/MX parses the escape syntax, disabling
escape processing has no effect.
java.sql.Statement.setFetchDirection(...)
The fetch direction attribute is ignored.
java.sql.Statement.setQueryTimeout(...)
The query time-out value is ignored. The JDBC Driver for
SQL/MX does not abort execution when the query
time-out period has expired.
The following features are implemented in the JDBC Driver for SQL/MX but might differ in implementation from other drivers:
Updatable Result Set
The JDBC Driver for SQL/MX supports both read-only and updatable concurrency modes. The JDBC Driver for SQL/MX expects the
following criteria for a result set to be updatable:
The table name of the first column in the result set is assumed to be the table to be updated. This assumption allows queries fr
q
om
multiple tables also to be updatable.
The query selects the primary key columns of the table to be updated.
q
The JDBC Driver for SQL/MX throws an SQLException when any of the following conditions occur:
The primary key columns are updated.
q
Any selected column has been updated since the most recent time it was read. (However, the JDBC Driver for SQL/MX does not
q
ensure that columns in the table that are not part of the select query remain unchanged since the row was most recently read.)
A query does not select nonnullable columns or columns that do not have a default value.
q
The result set is also affected in the following ways:
A deleted row is removed from the result set. The method
q
databaseMetaData.deletesAreDetected() returns false.
An inserted row is added to the result set at the current cursor position. The method
q
databaseMetaData.insertsAreDetected() returns true.
