The SQL analysis module provides decode summaries for TNS and TDS traffic. Structured Query Language (SQL) is a widely used standard for querying databases. When using SQL over a network, the queries and data are carried within special protocols, where the type of protocol used depends on the type of database environment. Oracle environments use Transparent Network Substrate (TNS). Sybase and Microsoft SQL Server environments use the Tabular Data Stream protocol (TDS).

The module provides TDS descriptions including Login, RPC, and SQL summary strings. For TNS, the module provides decode summaries for TNS Connect, Accept, Refuse, Redirect, Data, Abort, Resend, Marker, and Control packets. The analysis module provides this information to the Summary column in the Packets view of any capture window.
