```
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
  - 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.
