JDBC/MX 5.0 Driver for SQL/MX Programmer's Reference (SQL/MX 2.x)

int[] types)
its value is set to NULL because SQL/MX
does not support the base type.
java.sql.DatabaseMetaData.getVersionColumns()
Mimics the
DatabaseMetaData.getBestRowIdentifier()
method because SQL/MX does not support
SQL_ROWVER (a columns function that
returns the column or columns in the specified
table, if any, that are automatically updated by
the data source when any value in the row is
updated by any transaction).
java.sql.DriverManager.getConnection(String url,
String usr, String password)
java.sql.DriverManager.getConnection(String url,
Properties info)
javax.sql.DataSource.getConnection(String
username, String password)
User name and password arguments are
ignored. All connections have the same
security privileges as the user who invoked the
Java VM.
java.sql.DriverManager.setLoginTImeout(...)
javax.sql.DataSource.setLoginTimeout(...)
Login time-out is ignored.
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(...)
java.sql.Connection.prepareStatement(...)
The JDBC/MX driver does not support the
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)
java.sql.ResultSetMetaData.getColumnDisplaySize(int
column)
For CLOB and BLOB columns, these methods
return 0 to denote an unlimited value.
According to the standard API, 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/MX driver does not abort execution
when the query time-out period has expired.
javax.sql.JdbcRowSet.setUsername(String username)
User name and password arguments are
