Interface Parser
- public interface Parser
The Parser interface is intended to work with Jack-generated parsers (now JavaCC). We will specify "STATIC=false" when building Jack parsers - this specifies that the generated classes will not be static, which will allow there to be more than one parser (this is necessary in a multi-threaded server). Non-static parsers do not have to be re-initialized every time they are used (unlike static parsers, for which one must call ReInit() between calls to the parser).
| Method Summary | |
java.lang.String |
getSQLtext()
Returns the current SQL text string that is being parsed. |

org.apache.derby.impl.sql.compile.QueryTreeNode |
parseStatement(java.lang.String statementSQLText,
java.lang.Object[] paramDefaults)
Parses the given statement and returns a query tree. |
| Method Detail |
parseStatement
public org.apache.derby.impl.sql.compile.QueryTreeNode parseStatement(java.lang.String statementSQLText, java.lang.Object[] paramDefaults) throws org.apache.derby.iapi.error.StandardException
- Parses the given statement and returns a query tree. The query tree
at this point is a simple syntactic translation of the statement.
No binding will have taken place, and no decisions will have been
made regarding processing strategy.
