Lets see the following example: SELECT DECODE ( 1, 1, 'Equal' ); Code language: SQL (Structured Query Language) (sql) In this example, the DECODE () function compares the first argument (one) with the second argument (also one). type_text This defines the in which the input text we expect to be decoded. The collation specifications of the select expression and the search expressions must all be compatible. ('History', '17:15:00', '19:00:00'); Now, we have mixed encoded and decoded data in the tuitions table so whenever we try to retrieve the records by decoding the tuition_name we will get the exception. WebThis is the select expression. 5-10 yrs. Removes the longest string containing only bytes appearing in bytesremoved from the start, end, or both ends (BOTH is the default) of bytes.

SummaryThe DELETE statement is used for deleting one or more records from a table.To delete only select rows from a table, you can combine the DELETE statement with the WHERE clause.If the DELETE clause is used without the WHERE clause, it deletes all records from the table.More items Basically, encode supports different textual formats of string as follows: The decode function will raise an error if a backslash is not followed by either a second backslash or three octal digits; it accepts other byte values unchanged. The escape format converts zero bytes and bytes with the high bit set into octal escape sequences (\nnn), and it doubles backslashes. Table9.12. For details, see the Consider the following example where we will encode a string encode base64 string with format base64 by using the following SQL statement.
