Constructor Detail

ProgressQueryExpression

public ProgressQueryExpression(PersistenceFactory factory)
Creates an instance of this class.

Parameters:
factory - The persistence factory to be assigned against.
Method Detail

getStatement

public java.lang.String getStatement(boolean lock)
Description copied from class: JDBCQueryExpression
Creates a SQL statement. In general, for a RDBMS/JDBC driver with a full support of the SQL standard/JDBC specification, this will return a valid SQL statement. For some features, a particular RDBMS might indicate that it does not support this feature by throwing a SyntaxNotSupportedException.

Specified by:
getStatement in interface QueryExpression
Overrides:
getStatement in class JDBCQueryExpression
Parameters:
lock - True if a write lock is required
Returns:
The SQL statement
See Also:
QueryExpression.getStatement(boolean)

isLimitClauseSupported

public boolean isLimitClauseSupported()
Description copied from class: JDBCQueryExpression
Provides a default implementation of QueryExpression.isLimitClauseSupported().

Specified by:
isLimitClauseSupported in interface QueryExpression
Overrides:
isLimitClauseSupported in class JDBCQueryExpression
Returns:
false to indicate that this feature is not supported by default.
See Also:
QueryExpression.isLimitClauseSupported()
