Transact-SQL Syntax Conventions The following SQL Server string functions process on an input string and return a string or numeric value: Function Description; ASCII: Return the ASCII code value of a character: CHAR: Convert an ASCII value to a character: CHARINDEX: Search for a substring inside a string starting from a specified location and return the position of the substring. CONCAT: Join two or more strings into one.

The following SQL statement selects all customers with a City starting with L, followed by any character, followed by n, followed by any character, followed by on: Example SELECT * FROM Customer The following example shows three code examples. This first code example returns all rows (no WHERE clause is specified) and all columns (using the *) from the Product table in the AdventureWorks2012 database. SQL. USE AdventureWorks2012; GO SELECT * FROM Production.Product ORDER BY Name ASC; -- Alternate way The strcomp function may be appropriate here (returns 0 when strings are identical): SELECT * from table WHERE Strcmp(user, testername) <> 0 SQL Query : Select * from Customer where CONTAINS(First_name,'Amit'); The above query will fetch the customer data where First_name Contains string as 'Amit' Solution 4 : In PL SQL Building Block Or T-SQL block. User can check whether the String is there with using PL SQL Building blocks as well. For that we need to use CHARINDEX function

The SQL WHERE IN syntax. The general syntax is.

Before storing a value in any field of a table, a NULL value can be stored; later that NULL value can be replaced with the desired value. When a field value is NULL it means that the database assigned nothing (not even a zero 0 or blank ), in that field for that row. Since the NULL represents an unknown or inapplicable value, it can't be compared. The SELECT statement is the most complicated command in the SQL language. To make the description easier to follow, some of the passages below describe the way the data returned by a SELECT statement is determined as a series of steps. It is important to keep in mind that this is purely illustrative - in practice neither SQLite nor any other SQL engine is required to follow this or any other. Code language: SQL (Structured Query Language) (sql) In this syntax: input_string is any string expression to be searched.; substring is the substring to be replaced.; new_substring is the replacement string.; The REPLACE() function returns a new string in which all occurrences of the substring are replaced by the new_substring.It returns NULL if any argument is NULL
