How to concatenate columns in Teradata?

@august.kutch 

To concatenate columns in Teradata, you can use the CONCAT function. This function takes two or more strings as arguments and returns a single string that is the concatenation of the input strings.

Here is an example of how to use the CONCAT function to concatenate two columns in a Teradata SELECT statement:

1
2

SELECT CONCAT(column1, column2) AS concatenated_column
FROM table_name;

You can also use the CONCAT function to concatenate more than two columns. For example:

1
2

SELECT CONCAT(column1, column2, column3) AS concatenated_column
FROM table_name;

If you want to insert a separator between the concatenated columns, you can use the CONCAT function with the || operator, which represents string concatenation in Teradata. For example:

1
2

SELECT CONCAT(column1, ' - ', column2) AS concatenated_column
FROM table_name;

This will concatenate column1 and column2, with a dash (-) inserted between the two columns.

I hope this helps! Let me know if you have any questions.
