Detailed Description
vtkSQLQuery implementation for MySQL databases
This is an implementation of vtkSQLQuery for MySQL databases. See the documentation for vtkSQLQuery for information about what the methods do.
- Bug:
- Since MySQL requires that all bound parameters be passed in a single mysql_stmt_bind_param call, there is no way to determine which one is causing an error when one occurs.

Member Function Documentation
| static int vtkMySQLQuery::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkSQLQuery.
| virtual int vtkMySQLQuery::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkSQLQuery.
| static vtkMySQLQuery* vtkMySQLQuery::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |
Reimplemented from vtkSQLQuery.
| virtual vtkObjectBase* vtkMySQLQuery::NewInstanceInternal | ( | ) | const [protected, virtual] |
Reimplemented from vtkSQLQuery.
| vtkMySQLQuery* vtkMySQLQuery::NewInstance | ( | ) | const |
Reimplemented from vtkSQLQuery.
| void vtkMySQLQuery::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkSQLQuery.
| static vtkMySQLQuery* vtkMySQLQuery::New | ( | ) | [static] |
Create an object with Debug turned off, modified time initialized to zero, and reference counting on.
Reimplemented from vtkObject.
| bool vtkMySQLQuery::SetQuery | ( | const char * | query | ) | [virtual] |
Set the SQL query string. This must be performed before Execute() or BindParameter() can be called.
Reimplemented from vtkSQLQuery.
| bool vtkMySQLQuery::Execute | ( | ) | [virtual] |
Execute the query. This must be performed before any field name or data access functions are used.
Implements vtkSQLQuery.
| virtual bool vtkMySQLQuery::BeginTransaction | ( | ) | [virtual] |
Begin, commit, or roll back a transaction. Calling any of these methods will overwrite the current query text and call Execute() so any previous query text and results will be lost.
Reimplemented from vtkSQLQuery.
| virtual bool vtkMySQLQuery::CommitTransaction | ( | ) | [virtual] |
Begin, commit, or roll back a transaction. Calling any of these methods will overwrite the current query text and call Execute() so any previous query text and results will be lost.
Reimplemented from vtkSQLQuery.
| virtual bool vtkMySQLQuery::RollbackTransaction | ( | ) | [virtual] |
Begin, commit, or roll back a transaction. Calling any of these methods will overwrite the current query text and call Execute() so any previous query text and results will be lost.
Reimplemented from vtkSQLQuery.
| int vtkMySQLQuery::GetNumberOfFields | ( | ) | [virtual] |
The number of fields in the query result.
Implements vtkRowQuery.
| const char* vtkMySQLQuery::GetFieldName | ( | int | i | ) | [virtual] |
Return the name of the specified query field.
Implements vtkRowQuery.
| int vtkMySQLQuery::GetFieldType | ( | int | i | ) | [virtual] |
Return the type of the field, using the constants defined in vtkType.h.
Implements vtkRowQuery.
| bool vtkMySQLQuery::NextRow | ( | ) | [virtual] |
Advance row, return false if past end.
Implements vtkRowQuery.
| bool vtkMySQLQuery::HasError | ( | ) | [virtual] |
Return true if there is an error on the current query.
Implements vtkRowQuery.
| vtkVariant vtkMySQLQuery::DataValue | ( | vtkIdType | c | ) | [virtual] |
Return data in current row, field c
Implements vtkRowQuery.
| const char* vtkMySQLQuery::GetLastErrorText | ( | ) | [virtual] |
Get the last error text from the query
Implements vtkRowQuery.
| bool vtkMySQLQuery::BindParameter | ( | int | index, |
| unsigned char | value | ||
| ) | [virtual] |
Bind a parameter to a placeholder in a query. A full discussion of this feature is beyond the scope of this header file, but in short, here's how it works: Instead of saying "SELECT foo FROM mytable WHERE myfield = 12345" you can say "SELECT foo FROM mytable WHERE myfield = ?". The ? character is a placeholder for a parameter that must then be bound. Call BindParameter(0, 12345) to bind the integer value 12345 to that field. Placeholders are indexed starting at 0. You are responsible for making sure that the types match when you call BindParameter. You don't have to get it precisely correct: in general, the SQL driver is smart enough to do things like cast a short to a long or a float to a double. Bound parameters were introduced in ANSI SQL 92. Please see that standard for more information. Most of these methods are excluded from wrapping because the Java wrapper treats all integer types from char up through 64-bit long as 'int'. This is incorrect behavior but what else am I going to do? Finally, the default implementation for BindParameter(int, vtkVariant) dispatches to one of the more type-specific versions. It should be OK to use in database drivers without modification.
