| Method Summary | |
| int | addFilterColumns(TableFilter filter, HsqlArrayList columnList, int position)
| | void | checkTableWriteAccess(Table table, int userRight)
Tests whether the parsing session has the given write access on the
given Table object. | | void | clearParameters()
| | CompiledStatement | compileCallStatement()
Retrieves a CALL-type CompiledStatement from this parse context. | | CompiledStatement | compileDeleteStatement()
Retrieves a DELETE-type CompiledStatement from this parse context. | | CompiledStatement | compileInsertStatement()
Retrieves an INSERT_XXX-type CompiledStatement from this parse context. | | CompiledStatement | compileSelectStatement(int brackets)
Retrieves a SELECT-type CompiledStatement from this parse context. | | CompiledStatement | compileUpdateStatement()
Retrieves an UPDATE-type CompiledStatement from this parse context. | | static HsqlArrayList | getColumnNames(Database db, Table table, Tokenizer t, boolean full)
Parses a comma-separated, right-bracket terminated list of column
names. | | Expression[] | getParameters()
| | SubQuery[] | getSortedSubqueries()
| | SubQuery | getViewSubquery(View v)
| | boolean | isCompilingView()
| | int | parseCloseBrackets(int limit)
| | HashMappedList | parseColumnList()
| | Expression | parseExpression()
| | int | parseOpenBrackets()
| | int | parseOpenBracketsSelect()
| | Select | parseSelect(int brackets, boolean canHaveOrder, boolean canHaveLimit, boolean limitWithOrder, boolean isMain)
Constructs and returns a Select object. | | SubQuery | parseSubquery(int brackets, HsqlName[] colNames, boolean resolveAll, int predicateType)
The SubQuery objects are added to the end of subquery list. | | int | parseUnion(String token)
Parses the given token and any further tokens in tokenizer to return
any UNION or other set operation ID. | | static HashMappedList | processColumnList(Tokenizer tokenizer, boolean acceptAscDesc)
| | Expression | readCaseExpression()
reads a CASE .. | | Expression | readDefaultClause(int dataType)
Reads a DEFAULT clause expression. | | void | reset(String sql)
Resets this parse context with the given SQL character sequence. | | void | setAsView(View view)
| | void | setCompilingView()
|
| Parser | | Parser(Session session, Database db, Tokenizer t)(Code) | | Constructs a new Parser object with the given context.
Parameters:
db - the Database instance against which to resolve nameddatabase object references
Parameters:
t - the token source from which to parse commands
Parameters:
session - the connected context |
| checkTableWriteAccess | | void checkTableWriteAccess(Table table, int userRight) throws HsqlException(Code) | | Tests whether the parsing session has the given write access on the
given Table object.
Parameters:
table - the Table object to check
Parameters:
userRight - the numeric code of the right to check
throws:
HsqlException - if the session user does not have the rightor the given Table object is simply not writable (e.g. is anon-updateable View) |
| clearParameters | | void clearParameters()(Code) | | |
| getColumnNames | | static HsqlArrayList getColumnNames(Database db, Table table, Tokenizer t, boolean full) throws HsqlException(Code) | | Parses a comma-separated, right-bracket terminated list of column
names.
Parameters:
db - the Database instance whose name manager is to provide theresulting HsqlName objects, when the full argument is true
Parameters:
t - the tokenizer representing the character sequence to be parsed
Parameters:
full - if true, generate a list of HsqlNames, else a list ofString objects |
| getSortedSubqueries | | SubQuery[] getSortedSubqueries()(Code) | | Return the list of subqueries as an array sorted according to the order
of materialization, then clear the internal subquery list
|
| isCompilingView | | boolean isCompilingView()(Code) | | determines whether the parser is used for compiling a view
|
| parseSelect | | Select parseSelect(int brackets, boolean canHaveOrder, boolean canHaveLimit, boolean limitWithOrder, boolean isMain) throws HsqlException(Code) | | Constructs and returns a Select object.
Parameters:
canHaveOrder - whether the SELECT being parsed can have an ORDER BY
Parameters:
canHaveLimit - whether LIMIT without ORDER BY is allowed
Parameters:
limitWithOrder - whether LIMIT is allowed only with ORDER BY
Parameters:
isMain - whether the SELECT being parsed is the firstselect statement in the set a new Select object
throws:
HsqlException - if a parsing error occurs |
| parseSubquery | | SubQuery parseSubquery(int brackets, HsqlName[] colNames, boolean resolveAll, int predicateType) throws HsqlException(Code) | | The SubQuery objects are added to the end of subquery list.
When parsing the SELECT for a view, optional HsqlName[] array is used
for view column aliases.
|
| parseUnion | | int parseUnion(String token) throws HsqlException(Code) | | Parses the given token and any further tokens in tokenizer to return
any UNION or other set operation ID.
|
| reset | | void reset(String sql)(Code) | | Resets this parse context with the given SQL character sequence.
Internal structures are reset as though a new parser were created
with the given sql and the originally specified database and session
Parameters:
a - new SQL character sequence to replace the current one |
| setAsView | | void setAsView(View view)(Code) | | Sets the subqueries as belonging to the View being constructed
|
| setCompilingView | | void setCompilingView()(Code) | | sets a flag indicating the parser is used for compiling a view
