Updating values in sql


31-Dec-2019 20:03

When SET ANSI_PADDING OFF then CHAR data types are padded with spaces, VARCHAR data types have trailing spaces removed, and VARBINARY have trailing zeros removed.

For instance, if a field is defined as CHAR(10) and you update the value ‘Kris’ into this column, then it will be padded with six spaces.

Though this article uses the Adventure Works database for its examples, I’ve decided to create an example table for use within the database to help better illustrate the examples. The SQL UPDATE statement is used to change column values.

Though an update statement can modify columns data from many sources, such as literal values or other query results, the basic format is the same.

The reason we’re using a table variable is temporary and will be removed once query session is closed.

If you wanted to become a successful SQL programmer then working with tables is common and you have to face multiple problems too.

Some of the common ones are: In these cases, the UPDATE statement execution stops and the UPDATE generates an error.

No rows from the UPDATE statement are saved into the table, even those rows that didn’t generate an error.

There are several common reason an UPDATE statement may fail.

Before you start programming in the workplace, you must have a deep understanding of SQL basic commands how to use them to manage or store data in the database.

We will discuss the Update query in rest of the article below with detailed explanation.

The UPDATE statement is complex and there are many elements to consider. For a full list check out the UPDATE (Transact-SQL) article.

Keep in mind that when updating data in columns whose data type is CHAR, VARCHAR, or VARBINARY, the padding or truncation of data depends upon the SET ANSI_PADDING setting.New Value From [table] t1 join ( Select 'Foo' as New Value, 23 as My Id union all Select 'ASD' as New Value, 47 as My Id union all Select 'FGH' as New Value, 83 as My Id ) as derived1 on t1.
