Explain the following functions of Oracle with suitable examples: (i) To_Char( ) (ii) Count( ) (iii) Trim( ) (iv) Length( )
Ans: (i) To_char( ): The TO_CHAR function converts a DATETIME, number, or NTEXT expression to a TEXT expression in a specified format. This function is typically used to format output data.
(ii) Count( ): The COUNT function returns the number of rows in a query. The syntax for the COUNT function is: SELECT COUNT (expression) FROM tables WHERE predicates;
(iii) Trim( ): In Oracle/PLSQL, the trim function removes all specified characters either from the beginning or the ending of a string. The syntax for the trim function is: trim( [ leading | trailing | both [ trim_character ] ] string1 ) leading - remove trim_string from the front of string1. trailing - remove trim_string from the end of string1. both - remove trim_string from the front and end of string1.
(iv) Length( ): In Oracle/PLSQL, the length function returns the length of the specified string. The syntax for the length function is: length(string1) string1 is the string to return the length for. If string1 is NULL, then the function returnsNULL.
