Background

As a Database Administrator get so see a bit of SQL Statements.

Avenues

The SQL gets to the DBA through various avenues, inclusive :-

1. Developers
   • Submitted to review and execute against Production Database
2. Monitoring Tools

In quite a few cases, the first thing one has to do is space things out a bit.

Original

Here is our original SQL.

SELECT            dbo.lms_emp_aff_x.aff_netid,            dbo.lms_emp_aff_x.aff_loc,            dbo.lms_emp_aff_x.aff_emp_unique_loc_id,            'A',            @currdate,            ' '        FROM dbo.lms_emp_aff_x        WHERE dbo.lms_emp_aff_x.aff_loc = @loc_passed AND dbo.lms_emp_aff_x.aff_emp_unique_loc_id NOT IN            (              SELECT location_uid.lu_unique_loc_id              FROM location_uid              WHERE location_uid.lu_loc = @loc_passed AND location_uid.lu_record_type = 'A'           )
