Detailed Description

executes an sql query and retrieves results

The abstract superclass of SQL query classes. Instances of subclasses of vtkSQLQuery are created using the GetQueryInstance() function in vtkSQLDatabase. To implement a query connection for a new database type, subclass both vtkSQLDatabase and vtkSQLQuery, and implement the required functions. For the query class, this involves the following:

Execute() - Execute the query on the database. No results need to be retrieved at this point, unless you are performing caching.

GetNumberOfFields() - After Execute() is performed, returns the number of fields in the query results.

GetFieldName() - The name of the field at an index.

GetFieldType() - The data type of the field at an index.

NextRow() - Advances the query results by one row, and returns whether there are more rows left in the query.

DataValue() - Extract a single data value from the current row.

Begin/Rollback/CommitTransaction() - These methods are optional but recommended if the database supports transactions.

Thanks:: Thanks to Andrew Wilson from Sandia National Laboratories for his work on the database classes.

◆ BindParameter() [1/17]

virtual bool vtkSQLQuery::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.
