Get statistical data on the ODBC interface. Currently defined keys are:
Number of SQL statements that have been Created and Freed
over all connections. Statements executed with odbc_query/[2-3]
increment Created as the query is created and Freed
if the query is terminated due to deterministic success, failure, cut or
exception. Statements created with odbc_prepare/[4-5]
are freed by odbc_free_statement/1
or due to a fatal error with the statement.
