Both arguments can be a fixed-length character string, a variable-length character string, a binary expression, or an expression that evaluates to one of these inputs. The data type of the expression is the same type as the input arguments. If the input expressions are of different types, Amazon Redshift tries to implicitly type casts one of the expressions.

In this article, we will explore the syntax, working mechanism and other details of the CONCAT function in SQL and we will also make up various different examples about it. A string is a set of characters that helps to declare the texts in the programming languages. These are:. We have to take into account one point about the text and ntext data types. These data types are deprecated, and for this reason, we should try not to use these data types. We can use nvarchar max or varchar max instead. SQL string functions are used to manipulate the character expressions or to obtain various information about them. Now, we will go into the point with a simple example. In the following example, we will join three different integer values:. Otherwise, the result of the concatenation operation will be incorrect:.

When we hover the cursor on the SELECT operator icon, a pop-up window appears and the implicit conversion issue is showing obviously. Please refer to your browser's Help pages for instructions. We have to take into account one point about the text and ntext data db2 concat 3 strings.
