We can use the CHARINDEX() function to check whether a String contains a Substring in it. Name of this function is little confusing as name sounds something to do with character, but it basically returns the starting position of matched Substring in the main String. If it is not found then this function returns value 0.
Alternative to CHARINDEX() is using the LIKE predicate. Example 2 Demonstrates this.
Let us understand this with examples
Example 1: Using CHARINDEX() function
DECLARE @ExpressionToSearch VARCHAR(50) SET @ExpressionToSearch = 'Basavaraj Prabhu Biradar' --Check whether @ExpressionToSearch contains the substring --'Prabhu' in it IF CHARINDEX('Prabhu', @ExpressionToSearch ) > 0 PRINT 'Yes it Contains' ELSE PRINT 'It doesn''t Contain'
Example 2: Using LIKE Predicate
DECLARE @ExpressionToSearch VARCHAR(50) DECLARE @ExpressionToFind VARCHAR(50) SET @ExpressionToSearch = 'Basavaraj Prabhu Biradar' SET @ExpressionToFind = 'Prabhu' IF @ExpressionToSearch LIKE '%' + @ExpressionToFind + '%' PRINT 'Yes it Contains' ELSE PRINT 'It doesn''t Contain'
