SQL Check if string contains letters Check if string contains letters. To check if string contains letters uses the operator LIKE with the following regular expression '[A-Za-z]%'. Return all rows. DECLARE @MyVariable table (name varchar(250)); INSERT INTO @MyVariable(name) values ('abcABCdef');
For one leading letter, you can do: IF NOT ISNUMERIC(SUBSTRING(@MyString, 1, 1)) SET @MyString = SUBSTRING(@MyString, 2, LEN(@MyString)) You can repeat that until there are no more letters.
SQL Query : Select * from Customer. Where CHARINDEX(‘Amit’,First_Name) > 0. AND CHARINDEX(‘Sharma’,Last_Name) > 0; These are some real life examples of SQL Contains String where user can check the patterns of the String and fetch output accordingly.

SQL CASE Statement - Simple and Searched Forms, If there is no ELSE in the CASE statement, then it returns NULL. Notice that each WHEN clause now contains the test as a Boolean expression. The case statement is placed in the SELECT column list and returns a character value. If a value in the column or the expression is equal to any value in the list, the result of the IN operator is TRUE. The IN operator is equivalent to multiple OR operators, therefore, the following predicates are equivalent: column IN (v1, v2, v3) column = v1 OR column = v2 OR column = v3. To negate the IN operator, you use the NOT IN operator as follows:
