Dax contains string multiple values

The joined items can be text, numbers or Boolean values represented as text, or a combination of those items. You can also use a column reference if the column contains appropriate values. If you want to use text strings directly, rather than using a column reference, you must enclose each string in double quotation marks. This DAX function may return different results when used in a model that is deployed and then queried in DirectQuery mode.

The sample formula creates a new string value by combining two string values that you provide as arguments. The sample formula returns the customer's full name as listed in a phone book. Note how a nested function is used as the second argument.

This is one way to concatenate multiple strings, when you have more than two values that you want to use as arguments. The sample formula creates a new calculated column in the Customer table with the full customer name as a combination of first name, middle initial, and last name. If there is no middle name, the last name comes directly after the first name. If there is a middle name, only the first letter of the middle name is used and the initial letter is followed by a period.

The following example demonstrates how to concatenate values in columns that have different data types.

If the value that you are concatenating is numeric, the value will be implicitly converted to text. If both values are numeric, both values will be cast to text and concatenated as if they were strings. Skip to main content. Exit focus mode. Strings can include text or numbers.

You can also use column references. Return value The concatenated string. Example: Concatenation of Literals Description The sample formula creates a new string value by combining two string values that you provide as arguments. Example: Concatenation of Columns with Different Data Types The following example demonstrates how to concatenate values in columns that have different data types. Yes No. Any additional feedback?

See Remarks for details. For example, if users want to create a relationship between Table1 Column1, Column2 and Table2 Column1, Column2they can create two calculated columns, one on each table, as:. Unlike other DAX functions and operators, which are translated literally to the corresponding SQL operators and functions, the above relationship generates a SQL join predicate as:.

Column1 OR Table1. Column2 OR Table1. The join predicate can potentially deliver much better query performance than one that involves complex SQL operators and functions. The two rows are not joined together if both tables are from the same DirectQuery source although they are joined together if both tables are imported. Skip to main content. Exit focus mode. Must be a constant value.

Return value The concatenated string. Unlike other DAX functions and operators, which are translated literally to the corresponding SQL operators and functions, the above relationship generates a SQL join predicate as: Table1. Yes No. Any additional feedback? Skip Submit. Is this page helpful?The value that is returned when there is no value or more than one value in the specified column; if omitted, BLANK is returned for no value and an error is returned for more than one value.

In other words, the function will not return a lookup value if only some of the criteria match. However, in certain conditions it could include CallbackDataID requests in storage engine queries, resulting in slower execution, lower performance and missed cache hits.

When this happens, alternative approaches should be considered. However, it is often the case that these expressions are more dynamic, and this could generate a more expensive query plan that includes CallbackDataID requests to the storage engine.

It is better to store the TREATAS result in a variable for readability reasons, but the following code is also identical to the previous code from a query plan perspective:.

A benchmark of different solutions is always a good idea:. This article describes different techniques to retrieve multiple values from a lookup table in DAX, improving code readability and performance.

This article shows the equivalent syntaxes supported in DAX and it was updated in May Its usage is simple in a measure, but one might consider alternative syntax in calculated columns, as is explained in this article. Expanded tables are the core of DAX; understanding how they work is of paramount importance. This article provides a theoretical foundation of what expanded tables are, along with fundamental concepts useful when reading DAX code.

Do I need to have some sort of reference to the order number as well? Turn on suggestions.

The easiest way to do this would be to do the column in the query rather than the resulting data model table. Hit the Add Custom Column there and the code would be. If you want to do it in DAX it's a bit more messy.

My best idea is to search for the position of the text you want to find, and check for that to return an error when the text is missing. View solution in original post. Thanks for being so specific with the code too, that really helped. Much appreciated! Looks like I got A and B backwards. But I'd go with your first suggestion. How would I create a column that would give a value of "1" for "Car", "2" for "Truck" and "3" for "Bus"?

This is what I tried and it works.For example, consider the following two tables. The Promo table contains a number of promotions, with a primary key that corresponds to Month and Product. If you create both columns Campaign and Media for each Sales transaction in a table expression in DAX, you might use the following approach, which corresponds to what you would write in two calculated columns in the Sales table.

As you can see, there is a large amount of code duplicated for the two columns. Also from a performance point of view, the engine creates two different and independent subqueries to retrieve the values of the two columns.

The situation worsens if you need more columns. By using ROW we guarantee that there is always a row, even when there are no matching rows in the Promo table. This is important, because we want to display a blank value for Campaign and Media in case there are no rows found in Promo for a particular transaction in Sales.

Keep it in mind looking at the following example. If you can trust your data and you know that for a given combination of month and product there could be no more than one row in Promo, you can use this other syntax, which is also faster:.

You can use this approach as a way to join two tables using multiple columns. In fact, the previous result has only four rows instead of five. However, these functions require to join columns with the same name, type, and lineage. In the following example, the columns Month and Product used to join the two tables do not have the same lineage of the corresponding native columns.
