What is a row in SQL called?

In the context of a relational database, a row—also called a tuple—represents a single, implicitly structured data item in a table. Each column expects a data value of a particular type.

Is a record a row in SQL?

They refer to the same thing. Record is more of a database term. Row is more of a spreadsheet term. Very little in practice, most developers will not quibble over the distinction.

What is record in a database?

Is record and row same in SQL?

True, a table can have related many-to-one tables, but those are not stored contiguously, but they are stored logically related. So, a row is the thing in a table, and a record is the thing the developer works with in practical use.

What is the difference between row lock and page lock in SQL?

1 Answer 1. A row lock is the lowest level of granularity of locking possible in SQL Server. This means one or more specific rows will be locked, and the adjacent rows are still available for locking by concurrent queries. A page lock in SQL Server will lock 8K worth of data even when your query only needs 10 bytes from the page.

Can a row have multiple records in SQL?

A ROW may have multiple records: one in the clustered index, several in the NC indexes. A row that does not fit in page can be split between the record in the page and overflow records in the SLOB storage. A BLOB value of a field of a row can span several TEXT records in the BLOB storage.

How do I calculate the difference between two records in SQL?

To calculate a difference, you need a pair of records; those two records are “the current record” and “the previous year’s record”. You obtain this record using the LAG () window function. This function allows you to obtain data from the previous record (based on an order criterion, which here is “ ORDER BY year ”).
