Arithmetic overflow error converting numeric to data type numeric

I had encountered a while ago and had completely forgotten how the CONVERT(DECIMAL(p,s), 'hopefully some number') works.

Arithmetic overflow error converting numeric to data type numeric

Basically in DECIMAL(p,s), p (precision) equals to the number of digits on left of the decimal point and to the right hand side as well. s (scale) is the number of digits you need after the decimal point (right hand side)

Example: SELECT CONVERT(DECIMAL(10, 6), '2003201.8561484918793503') will return this error has the total number of digits to the left and right hand side to the decimal is of course more than 10 (which is our value of p)

For successfully converting the given value to decimal with 6 digits to the right is when p = 23

SELECT CONVERT(DECIMAL(23, 6), '2003201.8561484918793503') gives 2003201.856148

SQL Server: Database principal owns a schema in the database and cannot be dropped

Got this error today when i was playing around with login and user created selecting different options.

I had check db_datareader and db_datawriter in OwnedSchemas tab in Security >> Logins of the database server. This was causing the error and the fix was to transfer the schema ownership to a different login so we can drop the user we were trying to.

ALTER AUTHORIZATION ON SCHEMA::db_datareader to whome;
ALTER AUTHORIZATION ON SCHEMA::db_datawriter to whome;

Hope this helps someone and Google is my friend 😎

Find day, date, etc in SQL Server

I am not the original author of these queries and have found them while surfing as usual when looking for a quick solution.

BizTalk Artifacts Monitoring

I have to create jobs to monitor send ports, orchestrations and receive locations and this post will be update as i make progress.

Below is a list of things to remember and consider when creating these monitoring jobs:

• All BizTalk databases should not be considered as our usual databases and extreme caution should be practices when using them
• BizTalk installation has 4 databases BizTalkMsgBoxDb, BizTalkMgmtDb, BizTalkTrackingDb and SSODB
• These databases are dependent on each other and data is moved between them 
• Check on using WITH (READPAST): excludes locked rows from result set

To Be Cont....

SELECT TOP from @VAR and DISTINCT TOP @VAR

Simple and useful:

SELECT TOP (@MAX_REC_COUNT)
from DBO.MY_TABLE WITH (NOLOCK);

This way we can get the @max_rec_count from a config table instead of hard coding the record count to retrieve. This is useful when you can modify the config table from a UI instead of making code changes.

I wish there was a better way to get DISTINCT TOP @VAR from a query but unfortunately no better way than:

SELECT TOP @MAX_REC_COUNT 
FROM (
           SELECT DISTINCT COL1, COL2, ...COLN
           from DBO.MY_TABLE WITH (NOLOCK)
          ) XX;
