SQL and Support Debugging Tool Paul Johnson and Graham O’Bray

What’s You SQL IQ? Level 1 Select * from RM00101 Level 2 Update RM00101 set SLPRSNID=‘TOM’ where [STATE]=‘TX’ Level 3 Update c set c.COMMENT1 = dtInvCount.Invoices from RM00101 c join (Select CUSTNMBR, count(SOPNUMBE) as Invoices from SOP30200 group by CUSTNMBR) as dtInvCount on dtInvCount.CUSTNMBR = c.CUSTNMBR

Or are you…. Level 4 With cteCustTotals (CUSTNMBR, CUSTNAME, TotalAmount) as (Select c.CUSTNMBR, c.CUSTNAME, sum(s.DOCAMNT) as TotalAmount from RM00101 c join SOP30200 s on s.CUSTNMBR = c.CUSTNMBR and s.SOPTYPE = 3 group by c.CUSTNMBR, c.CUSTNAME) Select CUSTNMBR, CUSTNAME, TotalAmount, case when TotalAmount < 1000 then '1' when TotalAmount < 5000 THEN '2' when TotalAmount < then '3‘ when TotalAmount < then '4' when TotalAmount < then '5' else '6' end as CustLevel from cteCustTotals order by TotalAmount

Safe Query Development Rogue SQL Queries Minimize impact on production databases TOP N Clause WITH (NO LOCK) WHERE clause

Joins and Table Aliases Table aliases Provide plain language reference Easier to understand, follow scripts Simplifies joins Can also use field aliases

Joins and Table Aliases Combine Data from multiple tables/views with JOIN INNER LEFT OUTER RIGHT OUTER FULL OUTER CROSS JOIN Include components JOIN and ON

Handy SQL Keywords Comments: -- OR /* */ DISTINCT SELECT DISTINCT CUSTNMBR FROM SOP30200 RTRIM, for spaces SELECT RTRIM(CUSTNAME) AS : SELECT RTRIM(CUSTNAME) AS CUSTNAME CASE WHEN ELSE Example Later! LIKE WHERE CUSTNMBR LIKE ‘AA%’

Handy SQL Keywords (2) HAVING with GROUP BY GROUP BY CUSTNMBR HAVING COUNT (*) > 10 ORDER BY ORDER BY CUSTNMBER ISNULL ISNULL(ACTIDX, ‘None’) IN WHERE ACTIDX IN (3, 45, 56, 62) EXISTS WHERE EXISTS (SELECT * FROM…WHERE =)

Handy SQL Keywords (3) UNION Example Later! SUM, COUNT, MIN, MAX Used with GROUP BY, SUM(CUSTBLNC) BETWEEN WHERE CUSTBLNC BETWEEN AND Replaces >= and <= SELECT TOP SELECT TOP (10) PERCENT WITH TIES

Subqueries Query within a query or “nested” query Can be embedded in… Single Field Where Clause

Common Table Expressions Referred to as “CTE”s Allow you to setup complex subqueries separately Creates “tables” of information on the fly Temporary result set Nested SELECT statements Similar to a derived table but Self-reference Reference multiple times

More Demo Time! UPDATE with JOINS Multiple JOINS Comparisons (IN, NOT IN, WHERE NOT EXISTS) Information_Schema CASE WHEN ELSE Parameters UNION/UNION ALL PIVOT Views and Stored Procedures

Partition with ROWNUM ROW NUMBER allows for sequential numbering of records, RANK can be used instead for ranking OVER () stipulates the window over which the row numbering or ranking occurs PARTITION BY applies grouping without summarizing, to “reset” ranking or row numbering Can be based on a single field, or multiple fields

Finding Data

Dynamics GP Table Naming Structured as: a 2 or 3 character module code Followed by a 5 digit number Module code Ex. RM00101

Dynamics GP Table Naming More module code examples Payables Management – PM General Ledger – GL Inventory Control – IV

Dynamics GP Table Naming The first digit represents the table type Master – 0 Work – 1 Open – 2 Table History – 3 Ex. RM0010

Dynamics GP Table Naming The second and third digits are sequences. Sequence Number Ex. RM00101 Variants The fourth and fifth digits are variants.

Dynamics GP Field Naming Earlier GP versions were limited to 8 character names Ex. Customer Number – CUSTNMBR

Dynamics GP Views A view is a virtual table Cannot hold information, but will query tables and present data differently Can join multiple tables: Ex. Open and history

Data Table Resources Listing of commonly used tables and good explanations of fields where index numbers are used (ex. SOP Document Type: Quote = 1, Order = 2, invoice = 3)

Tools used to write Statements SSMS – SQL Server management studio Support debugging tool (Sql execute) Many other free tools Need to create a connection to database
