#Concatenate fields scriptcase plus

Using CONCAT SELECT CONCAT ( 'Happy ', 'Birthday ', 11, '/', '25' ) AS Result Д«. For older linked servers, the CONCAT operation will happen locally, after the linked server returns the non-concatenated values. The CONCAT function can be executed remotely on a linked server of version SQL Server 2012 (11.x) and above. The limitation of this method is if any of the fields you are concatenating are NULL, the final string value is NULL.

#Concatenate fields scriptcase plus

This truncation preserves space and supports plan generation efficiency. Prior to SQL Server 2012 concatenation was accomplished by using the plus (+) sign to concatenate fields together of various data types (varchar, char, int, numeric, etc.).

If none of the input arguments has a supported large object (LOB) type, then the return type truncates to 8000 characters in length, regardless of the return type. Therefore, a concatenation of two integers returns a result with a length of no less than 24. For example, an int (14) has a string length of 12, while a float has a length of 32. Other data types have different lengths when implicitly converted to strings. When CONCAT receives nvarchar input arguments of length <= 4000 characters, or varchar input arguments of length <= 8000 characters, implicit conversions can affect the length of the result. In that case, CONCAT returns a result of type nvarchar(max). Varchar(<= 8000) (a varchar of at most 8000 characters) unless one of the parameters is an nvarchar of any length. Otherwise, any argument of type nvarchar of at most 4000 characters In this case, CONCAT returns a result of type nvarchar(max).ДЈ. Varchar(max), unless one of the parameters is an nvarchar of any length. This table illustrates the mapping: Input type The return type depends on the type of the arguments. See CAST and CONVERT (Transact-SQL) for more information about data type conversions. The implicit conversion to strings follows the existing rules for data type conversions.

If CONCAT receives arguments with all NULL values, it will return an empty string of type varchar(1). CONCAT implicitly converts null values to empty strings. CONCAT implicitly converts all arguments to string types before concatenation. It requires a minimum of two input values otherwise, CONCAT will raise an error. RemarksД¬ONCAT takes a variable number of string arguments and concatenates (or joins) them into a single string. Return typesДЄ string value whose length and type depend on the input. The CONCAT function requires at least two string_value arguments, and no more than 254 string_value arguments. ArgumentsДЄ string value to concatenate to the other values.
