# Solved: how to get notinteger value

Sure, let’s delve into the topic of obtaining a non-integer value in SQL. SQL or Structured Query Language is a standard language for dealing with relational databases. SQL can be effectively used to insert, search, update, delete database records. That doesn’t mean SQL cannot do things beyond that. In fact, SQL has many more advanced features that provide powerful insights when working with data.

Obtaining non-integer values is quite a normal requirement in SQL. For instance, in certain calculations, you may need to perform divisions and want to obtain a precise result which often comes as a non-integer.

Now let’s delve into the ways to acquire such a non-integer value.

## The CAST Function

One approach to get non-integer value in SQL involves utilizing the CAST function. The CAST function in SQL converts data from one data type to another. For numeric values, the syntax is as follows:

```    SELECT CAST(column_name AS DECIMAL) FROM table_name
```

## The CONVERT Function

Another function in SQL that plays a similar role is the CONVERT function. Here is how you can use it:

```    SELECT CONVERT(DECIMAL, column_name) FROM table_name
```

Both these functions force the division to occur in floating point arithmetic and as a result, you should get a non-integer value. This ability to control the arithmetic precision is crucial for various aspects of data analysis including computations involving averages, rankings and so much more.

## Vital Tips for Implementing These Functions in Your Database

• Always be clear about the data type you are working with. The above functions work when the column_name is initially an integer type.
• Review your results. Even if your SQL script runs without error, it’s always a good habit to do a sense-check of the outputs. If you expect a non-integer and you’re getting an integer, then you must review your SQL script for potential issues.

Obtaining non-integer values in SQL is a profound aspect of data analysis, and not just for divisions. Other operations and conditions also need such types, which becomes achievable through the CAST and CONVERT functions, key tools in the SQL developer’s arsenal. Using them appropriately can constitute a huge difference in the precision of your results and the overall efficiency of your data operation.

## The Importance of Non-Integer Values in SQL

Non-integer values in SQL are particularly important because they allow for more precise calculations. They play a pivotal role in calculations where precision is the game, such as financial calculations. It is an excellent practice to be familiar with how to handle non-integer values, and the functions and techniques discussed in this article should provide a solid basis towards gaining that mastery.
