WHERE function
5 MIN EXPERT DATA, SQL QUERIES, SQL WHERE, WHERE QUERY
This functionality is only available in Spotzi Studio.
If you want to select particular rows of your dataset and view this selection in your MY DATA page you have to use a WHERE query. The WHERE clause is used to filter records and extract only those records that match a specific condition (the WHERE condition).
SELECT * FROM {name of dataset}
WHERE {condition};
In the example below we have a dataset with 2-digit postal codes from the US. Each postal code area has one sales manager, but a sales manager can be responsible for several postal code areas.

Let’s say we only want to show the areas where Adam is the sales manager. The WHERE query for this case has the following syntax:
SELECT * FROM usa_salesmanagers_2_digit_areas
WHERE salesmanager='Adam';

Quick tip! Difference between numbers and text
Remember that when you create a query you have to take the data type into account. When you are trying to filter based on a field of type text (string) you have to put the value you are searching between single quotes (‘ ‘). If you are trying to filter based on a field of type number, do not use quotes.
Operators in the WHERE clause
In the example above we used the ” = “-operator. This operator only allows you to select rows based on one single condition. With other operators it is also possible to select rows based on certain numbers or letters. In the table below you can find an overview of these operators.
Operator | Description |
---|---|
= | Equal |
<> | Not equal. Note: In some versions of SQL this operator may be written as != |
> | Greater than |
< | Less than |
>= | Greater than or equal |
<= | Less than or equal |
BETWEEN | Between an inclusive range |
LIKE | Search for a pattern |
IN | To specify multiple possible values for a column |
AND | To specify multiple possible conditions separated by AND |
OR | To specify multiple possible conditions separated by OR |
NOT | To specify a condition when not true |
