Language Used By The Relational Database Management System (RDBMS).  Differences: Differences:  WHERE Masking Using LIKE (% vs *) WHERE Masking Using LIKE (% vs *)  Functions Functions  Mostly – Generic Statement Will Work Across Databases Mostly – Generic Statement Will Work Across Databases  Allows Selecting, Inserting And Updating Records Into A Table Allows Selecting, Inserting And Updating Records Into A Table FOCUS To SQL Demystified – What IS SQL?

6 Copyright 2007, Information Builders. Slide 6  SQLAGGR  Displays Data Adapter ‑ to ‑ RDBMS Aggregation And Join Analysis.  Used Only For Focus Reporting Operations Such As Table, Graph, And Match File.  If The Data Adapter Is Able To Pass All Join, Sort, And Aggregation Operations, The SQLAGGR Trace Is Not Populated. The Message "AGGREGATION DONE..." Appears.  Formerly FSTRACE3. FOCUS To SQL Demystified – TRACE Settings

7 Copyright 2007, Information Builders. Slide 7  STMTRACE  Records SQL SELECT Statements Generated By The Data Adapter For FOCUS Report Requests.  Modify Procedures, Or Direct Sql Passthru Select Requests. It Also Records The SQL Data.  Definition Language (DDL) Statements Generated By The Create File Command.  Display The Trace Information Online.  Store It In A File Or Sequential Data Set.  The Data Adapter Terminates Its Generated SQL Select Statements With A Semicolon.  You Can Submit Them To The RDBMS For Processing, Interactively Or In Batch.  Use STMTRACE for:  Debugging.  Performance Tuning.  Capturing SQL Data Definition And Data Manipulation Statements To Reuse.  Formerly FSTRACE4.
