If you specify HIDE DEFAULTS, then no such elements or attributes are included in the output. The DECODE function can be used in Oracle/PLSQL. If you specify SHOW DEFAULTS and the input data is missing any optional elements or attributes for which the XML schema defines default values, then those elements or attributes are included in the output with their default values. HIDE DEFAULTS and SHOW DEFAULTS apply only to XML schema-based data. If you omit this clause, then the behavior (pretty-printing or not) is indeterminate. If INDENT is present without a SIZE specification, then 2-space indenting is used. If N is 0, then pretty-printing inserts a newline character after each element, placing each element on a line by itself, but omitting all other insignificant whitespace in the output. Specify INDENT SIZE = N, where N is a whole number, for output that is pretty-printed using a relative indentation of N spaces. Specify NO INDENT to strip all insignificant whitespace from the output. Specify the VERSION clause to use the version you provide as string_literal in the XML declaration ( ). The xml_encoding_spec is an XML encoding declaration ( encoding="."). If datatype is BLOB, then you can specify the ENCODING clause to use the specified encoding in the prolog. The datatype specified can be a string type ( VARCHAR2 or VARCHAR, but not NVARCHAR2), BLOB, or CLOB. If you specify CONTENT, then the value_expr need not be a singly rooted XML document. If you specify DOCUMENT, then the value_expr must be a valid XML document. This includes the expression, search, and result arguments.XMLSerialize creates a string or LOB containing the contents of value_expr.Īny lob returned by XMLSERIALIZE will be read-only. Question: Is there a limit to the number of arguments that you can have in one DECODE statement? I'm getting an error, "ORA-00939: too many arguments for function".Īnswer: Yes, the maximum number of components that you can have in a DECODE function is 255. If yrs_of_service = 1 and 5 then return 0.06Īnswer: You will need to create a formula that will evaluate to a single number for each one of your ranges.ĭECODE(TRUNC (( yrs_of_service 3) / 4), 0, 0.04, Question: I need to write a DECODE statement that will return the following: The formula will evaluate to 2, if the supplier_id is between 21 and 30. Step 1 : You can create separate column of XMLType in table level to store the XML type data. The formula will evaluate to 1, if the supplier_id is between 11 and 20. But Here i would like to give you some important examples for the same. The formula will evaluate to 0, if the supplier_id is between 1 and 10. In this example, based on the formula: TRUNC ((supplier_id - 1) / 10 XML Encoding in XMLTYPE column in Oracle DB Ask Question Asked 5 years ago Modified 5 years ago Viewed 11k times 3 I have a table created like this: create table b (data timestamp, value XMLTYPE) I run this script in TOAD 12.6 to store a XML in the table. However, you can try to create a formula that will evaluate to one number for a given range, and another number for the next range, and so on.ĭECODE(TRUNC ((supplier_id - 1) / 10), 0, 'category 1', Question: I would like to know if it's possible to use the DECODE function for ranges of numbers, ie 1-10 = 'category 1', 11-20 = 'category 2', rather than having to individually decode each number.Īnswer: Unfortunately, you can not use the DECODE function for ranges of numbers. The date example above could be modified as follows: LEAST(date1, date2) Helpful Tip #2: One of our viewers suggested using the LEAST function (instead of the DECODE function) as follows: Sales Bonuses DECODE(SIGN(actual-target), -1, 'NO Bonus for you', 0,'Just made it', 1, 'Congrats, you are a winner') : Character ')' is not allowed in an XML tag name. The SIGN/DECODE combination is also helpful for numeric comparisons e.g. decode function in OracleXMLQuery 3004 selectStr 'SELECT DECODE (email,null,'',email), FROM mytable WHERE userid\'' searchid '\'' using this select statement in conjunction with OracleXMLQuery produces the following exception. The date example above could be modified as follows: DECODE(SIGN(date1-date2), 1, date2, date1) Helpful Tip #1: One of our viewers suggested combining the SIGN function with the DECODE function as follows: The formula below would equal 0, if date1 is greater than date2: (date1 - date2) - ABS(date1 - date2) Otherwise, the DECODE function should return date1.Īnswer: To accomplish this, use the DECODE function as follows: DECODE((date1 - date2) - ABS(date1 - date2), 0, date2, date1) Question: One of our viewers wanted to know how to use the DECODE function to compare two dates (ie: date1 and date2), where if date1 > date2, the DECODE function should return date2.
