Example3: This example will use the CONCAT() function that takes more than two input string and return those string into a single output after concatenation: Executing the query will display the below output: Example4: This example uses the SOUNDEX() function that accepts a string as input and produces a four-character string based on how it is spoken. When using POCO entity types, EF achieves lazy loading by creating instances of derived proxy types during runtime and then overriding virtual properties in your classes to add the loading hook. Email_ID = REPLACE('Email_ID', 'com', 'simplilearn.org'); As you can see in the output, instead of changing the substring, the replace() function changed the entire columns field to Email_ID as you had passed it as a literal string and not a column. raise_error(expr) - Throws an exception with expr. expr is [0..20]. exception to the following special symbols: _ matches any one character in the input (similar to . This function converts the lower case character into the upper case. upper(str) - Returns str with all characters changed to uppercase. Then when you call execute, the prepared statement is combined with the parameter values Contact_No = REPLACE(Contact_No, '. unix_timestamp([timeExp[, fmt]]) - Returns the UNIX timestamp of current or specified time. arc cosine) of expr, as if computed by replace(str, search[, replace]) - Replaces all occurrences of search with replace. year(date) - Returns the year component of the date/timestamp. array_distinct(array) - Removes duplicate values from the array. string(expr) - Casts the value expr to the target data type string. xpath_boolean(xml, xpath) - Returns true if the XPath expression evaluates to true, or if a matching node is found. position(substr, str[, pos]) - Returns the position of the first occurrence of substr in str after position pos. inline(expr) - Explodes an array of structs into a table. expr2, expr4, expr5 - the branch value expressions and else value expression should all be signum(expr) - Returns -1.0, 0.0 or 1.0 as expr is negative, 0 or positive. nullReplacement, any null value is filtered. we just replace the "SELECT *" with DELETE. value would be assigned in an equiwidth histogram with num_bucket buckets, This article explains a complete overview of several SQL Server's built-in string functions, as well as some examples and pictures.
