T-SQL has some well known limitations when working with parameters for a stored procedure, not the least of which is a variable number of parameters.

You can improve your SQL performance by using indexes. But you have to choose the proper indexes and make sure the ones you do choose fit into your business situation. In this indexing guide, you will find answers to common indexing questions, indexing dos and don'ts, and tricks for working with the Index Tuning Wizard to improve overall system performance for SQL Server 2000 servers.

Have you ever wanted to create your own utility procedures in SQL Server? Maybe your own information schema view? SQL Server export David Poole brings us an article dicussing these very topcis and offers advice on how to proceed.
A SQL Server DBA often needs to perform ad hoc operations on data in their databases. The tasks can typically be handled with simple T-SQL statements, but other times a more complex operation is called for – and having to manually enter all the T-SQL code necessary for such an operation is not appealing! It can be difficult to perfect the syntax, and tedious to list column names once, twice or even three times. Fortunately, useful template code can be easily generated instead of being entered by hand.
A defense-in-depth strategy, with overlapping layers of security, is the best way to counter these threats, and the least-privileged user account (LUA) approach is an important part of that defensive strategy. The LUA approach ensures that users follow the principle of least privilege and always log on with limited user accounts. This strategy also aims to limit the use of administrative credentials to administrators, and then only for administrative tasks.

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
