iAnywhere.com - Executing SQL statements

ODBC includes several functions for executing SQL statements:

Direct execution Adaptive Server Anywhere parses the SQL statement, prepares an access plan, and executes the statement. Parsing and access plan preparation are called preparing the statement.
Prepared execution The statement preparation is carried out separately from the execution. For statements that are to be executed repeatedly, this avoids repeated preparation and so improves performance.
