My client wants to standardize address information for existing and future addresses collected for their customers, particularly the street suffixes. The application used to enter and collect address information has the street suffix separated from the address field, but it is a textbox instead of a drop down list therefore things are not standardized. I know there are some options out there to standarize data, but they would like a less expensive alternative. Are there any functions in SQL Server that I can use to standardized data?

In an ETL solution, error logging is a fundamental requirement for various aspects of the application and is very useful at various stages of the ETL execution life-cycle. Let's consider a scenario where our requirement is to insert records into a SQL Server table. The package should attempt loading all the records and whichever records fail, error details reported by the database engine should be reported. We will look at how to implement this in a SSIS package.

I have some data in a table:
CREATE TABLE #test_data
(
id INT PRIMARY KEY,
name VARCHAR(100),
birth_date DATE
);
-- Step 2: Insert rows
INSERT INTO #test_data
VALUES
(1, 'Olivia', '2025-01-05'),
(2, 'Emma', '2025-03-02'),
(3, 'Liam', '2025-11-15'),
(4, 'Noah', '2025-12-22');
If I run this query, how many rows are returned?
SELECT t1.[key] AS row,
t2.*
FROM OPENJSON(
(
SELECT t.* FROM #test_data AS t FOR JSON PATH
)
) t1
CROSS APPLY OPENJSON(t1.value) t2; See possible answers
