Great cheatsheet, missing one thing. can you add the range for the numerics data types.
Theb it would be perfect.

I second mrfatmen, adding the type size would be nice.

I like it, but what about datetime2 ? :-)

How about syntax-basics (SELECT, DELETE, UPDATE, etc.), some different JOINs, CTEs, and and and?

SELECT AFC.CASE_NUMBER AS 'CASE NUMBER', COUNT(AFC.CASE_NUMBER) AS CTOTAL, AETC.EVENT_ENTRY_ID, AEE.EVENT_ENTRY_DESC AS 'EVENT DESCRIPTION', AEE.EVENT_ENTRY_TYP_ID AS 'EVENT TYPE',
AETC.EVENT_DT AS 'EVENT DATE'
, COUNT(AEE.EVENT_ENTRY_TYP_ID) AS EVENTS
FROM dbo.ACM_FACTS_CASE AS AFC INNER JOIN
dbo.ACM_EVENT_TO_CASE AS AETC ON AFC.CASE_ID = AETC.CASE_ID INNER JOIN
dbo.ACM_EVENT_ENTRY AS AEE ON AETC.EVENT_ENTRY_ID = AEE.EVENT_ENTRY_ID
WHERE (AEE.EVENT_ENTRY_DESC LIKE '%mandate%')
and AETC.EVENT_DT between '2016-07-01' and '2018-06-30'

HAVING AEE.EVENT_ENTRY_TYP_ID > 1

ORDER BY AFC.CASE_NUMBER, AEE.EVENT_ENTRY_TYP_ID

Msg 8121, Level 16, State 1, Line 10
Column 'dbo.ACM_EVENT_ENTRY.EVENT_ENTRY_TYP_ID'
is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.
