REPLICATE FUNCTION IN SQL SERVER 2005

REPLICATE function repeats a given string specified number of times.

The syntax : REPLICATE ( string_expression ,integer_expression )

Eg.

2. SELECT REPLICATE (100 , 5 ) — It is taking integer value also.

OUTPUT

3. SELECT REPLICATE (100 , -1 ) — It will return null if the integer value is negative

OUTPUT
_________________

NULL

4. SELECT REPLICATE (100 , 0 ) — It will return blank

5. SELECT REPLICATE (100 , ‘one’ ) — It will give you syntax error

OUTPUT
_________________
Msg 245, Level 16, State 1, Line 1
Conversion failed when converting the varchar value ‘one’ to data type int.

REPLICATE function can be used to combine it with other string
functions and replace leading or trailing spaces with another character.

In the below example we are replacing spaces with character 1

DECLARE @StringInput VARCHAR(40)
SELECT @StringInput= ‘         PAWAN KUMAR’
SELECT @StringInput =  REPLICATE(‘1’, LEN(@StringInput) – LEN(LTRIM(@StringInput)))  + LTRIM(@StringInput)
SELECT @StringInput
