REPLICATE (SSIS Expression)
Returns a character expression that is replicated a number of times. The times argument must evaluate to an integer.
The REPLICATE function frequently uses long strings, and therefore is more likely to incur the 4000-character limit on expression length. If the evaluation result of an expression has the Integration Services data type DT_WSTR or DT_STR, the expression will be truncated at 4000 characters. If the result type of a sub-expression is DT_STR or DT_WSTR, that sub-expression likewise will be truncated to 4000 characters, regardless of the overall expression result type. The consequences of truncation can be handled gracefully or cause a warning or an error. For more information, see Syntax (SSIS).
Is a character expression to replicate.
Is an integer expression that specifies the number of times character_expression is replicated.
If times is zero, the function returns a zero-length string.
If times is a negative number, the function returns an error.
The times argument can also use variables and columns.
REPLICATE works only with the DT_WSTR data type. A character_expression argument that is a string literal or a data column with the DT_STR data type is implicitly cast to the DT_WSTR data type before REPLICATE performs its operation. Other data types must be explicitly cast to the DT_WSTR data type. For more information, see Integration Services Data Types and Cast (SSIS Expression).
REPLICATE returns a null result if either argument is null.
This example replicates a string literal three times. The return result is "Mountain BikeMountain BikeMountain Bike".
REPLICATE("Mountain Bike", 3)
This example replicates values in the Name column by the value in the Times variable. If Times is 3 and Name is Touring Front Wheel, the return result is Touring Front WheelTouring Front WheelTouring Front Wheel.
This example replicates the value in the Name variable by the value in the Times column. Times has a non-integer data type and the expression includes an explicit cast to an integer data type. If Name contains Helmet and Times is 2, the return result is "HelmetHelmet".
