In this article, I am going to discuss Conversion Functions in Oracle with Examples. The optional DEFAULT return_value ON CONVERSION ERROR clause allows you to specify the value this function returns if an error occurs while converting char to DATE. This argument can have the following form: By default, SQLcl and SQL*Plus return a blank space whenever null occurs as a result of a SQL SELECT statement. The 'nlsparam' argument specifies the language in which month and day names and abbreviations are returned. It's the YEAR keyword that extracts the year part from the date. The default date format is determined implicitly by the NLS_TERRITORY initialization parameter or can be set explicitly by the NLS_DATE_FORMAT parameter. Output: Example: Display employees who are joined on MONDAY by using TO_CHAR() function. Here are some examples of the DECODE function. In this post, I will introduce Oracle TO_DATE, SQL function in two parts: Oracle TO_DATE Syntax Oracle TO_DATE Examples SELECT TO_CHAR(SYSDATE,DDD DD D DAY DY) FROM DUAL; Oracle Date Functions Oracle Date Functions This page provides you with the most commonly used Oracle date functions that help you handle date and time data easily and more effectively. The function converts return_value to DATE using the same method it uses to convert char to DATE. -- Convert the current date to YYYY-MM-DD format SELECT TO_CHAR ( SYSDATE, 'YYYY-MM-DD . SELECT * FROM EMP WHERE TO_CHAR(HIREDATE,YYYY)=1981 AND TO_CHAR(HIREDATE,Q)=2; This function does not support CLOB data directly. The parameters of the NEW_TIME function are: input_date (mandatory): The date, including time, that is to be converted. TO_CHAR function in Oracle. Output: Example: Display the employees who are joined in 2nd quarter of 1981. In Oracle, TO_CHAR function converts a datetime value (DATE, TIMESTAMP data types i.e.) SELECT * FROM EMP WHERE TO_CHAR(HIREDATE,MMYYYY)=021981; SELECT TO_CHAR(SYSDATE,DDD DD D DAY DY) FROM DUAL; Example: Display employees who are joined on MONDAY by using TO_CHAR() function. SELECT * FROM EMP WHERE TO_CHAR(HIREDATE,MM) IN(02,05,12); In reality, it converts any value which has a data type of CHAR, VARCHAR2, NCHAR, or NVARCHAR2 into a value which has the data type of DATE. 1 JAN MAR 1 2 3 The TO_CHAR () function is used to convert date and time into a character string according to the given format. Syntax The syntax goes like this: TO_CHAR ( { datetime | interval } [, fmt [, 'nlsparam' ] ]) Where: -- Convert the current date to YYYY-MM-DD format SELECT TO_CHAR ( SYSDATE, 'YYYY-MM-DD . The result for a TIMESTAMP WITH LOCAL TIME ZONE column is sensitive to session time zone, whereas the results for the TIMESTAMP and TIMESTAMP WITH TIME ZONE columns are not sensitive to session time zone: The following example converts an interval literal into a text literal: Oracle Database Globalization Support Guide, Description of the illustration to_char_date.eps, Security Considerations for Data Conversion. In SQL Server, you can use CONVERT or CAST functions to convert a datetime value (DATETIME, DATETIME2 data types i.e.) You can use this function in conjunction with any of the XML functions to generate a date in the database format rather than the XML Schema standard format. Output: Example: Display employees who are joined in years 1980,1982,1987 by using TO_CHAR() function. mdy () - Convert character in month-day-year format to date. The example shows the results of applying TO_CHAR to different TIMESTAMP data types. Syntax It has a pretty simple one liner syntax and easy to remember: All in One Data Science Bundle (360+ Courses, 50+ projects) Price Likewise in SQL, the to_date function in Oracle, a widely used string conversion technique used by database developers and administrators basically to convert a character value to date (DATETIME) datatype. select to_char (sysdate,'DD-MON-YYYY') AS REQ_DATE from dual; -- Output-- 01-FEB-2017 select to_char (sysdate,'DD Month') AS REQ_DATE from dual; -- Output-- 01 February to a string. SELECT TO_CHAR(SYSDATE,Q) FROM DUAL; You must select these functions with another column; they cannot be selected alone. "Datetime Format Models" and "Data Type Comparison Rules" for more information. If you omit fmt, then date is converted to a VARCHAR2 value as follows: DATE values are converted to values in the default date format. If fmt is J, for Julian, then char must be an integer. This function does not convert data to any of the other datetime data types. you must select these functions with another column; they cannot be selected alone. The fmt is a datetime model format specifying the format of char. format_mask Optional. In SQL Server, you can use CONVERT or CAST functions to convert a datetime value (DATETIME, DATETIME2 data types i.e.) SELECT * FROM EMP WHERE TO_CHAR(HIREDATE,DAY)=MONDAY; Example: Display employee on which day employees are joined. This specifies the format that will be used to convert the value to a string. Was this tutorial helpful? I know that this is my sessions default date format because I queried the V$NLS_PARAMETERS view, which shows me the current value of the NLS parameters. 3 JUL SEP DATE values are converted to values in the default date format. SELECT TO_DATE(08-AUG-2020)+10 FROM DUAL; You can use various functions from the lubridate package in R to convert a character column to a date format.

Do not use the TO_DATE function with a DATE value for the char argument. The first two digits of the returned DATE value can differ from the original char, depending on fmt or . Here I specified that the string null should be returned. If you omit fmt, then date is converted to a VARCHAR2 value as follows: Example 1. The TO_CHAR function in Oracle is used to convert a DateTime or interval value of DATE, TIMESTAMP, TIMESTAMP WITH TIME ZONE, or TIMESTAMP WITH LOCAL TIME ZONE data type to a value of VARCHAR2 datatype in a specified format. SELECT TO_CHAR(SYSDATE,MM MON MONTH) FROM DUAL; Please use the below SQL script to create and populate the EMP table with the required data. SELECT * FROM EMP WHERE TO_CHAR(HIREDATE,MMYYYY)=021981; As a user, we can use the following two functions to convert explicitly. SELECT ENAME|| ||JOINED ON|| ||TO_CHAR(HIREDATE,DAY) FROM EMP; Note: In oracle whenever we use TO_CHAR() and also within TO_CHAR() when we use day/month format then the oracle server internally allocates some extra memory for the day/month format of data. It doesn't convert the value into any of the other datetime datatypes. Output: Example: When it is used without a format mask, the function is valid only if char uses the same format as is determined by the NLS_TERRITORY or NLS_DATE_FORMAT parameters. TO_DATE converts char of CHAR, VARCHAR2, NCHAR, or NVARCHAR2 data type to a value of DATE data type. SELECT TO_CHAR(SYSDATE,YYYY YY YEAR CC AD) FROM DUAL; Example: Display Employees who are joined in the Year 1982 from the EMP table by using TO_CHAR() function. "Security Considerations for Data Conversion". For example, DY is a format element, as is DD, MONTH, etc. SELECT TO_CHAR(SYSDATE,YYYY YY YEAR CC AD) FROM DUAL; In Oracle, TO_CHAR function converts a datetime value (DATE, TIMESTAMP data types i.e.) The following is the syntax to use the TO_CHAR function in oracle. Furthermore, the function may not be stable across databases unless the explicit format mask is specified to avoid dependencies. to a string. The purpose of the TO_DATE function in Oracle is to convert a character value to a date value. We are going to use the following EMP table to understand the Oracle Conversion Functions with examples. The second argument provides the format model. In some cases, the Oracle Server uses data of one type where it expects data of a different data type. Syntax: TO_CHAR (expression, date_format) Parameters: expression: It refers to the DATE or an INTERVAL value which needs to be converted. Output: Example: The TO_CHAR function returns a string value. This is the format that will be used to convert string1 to a date. TIMESTAMP and TIMESTAMP WITH LOCAL TIME ZONE values are converted to values in the default timestamp format. Interval values are converted to the numeric representation of the interval literal. In other words, TO_DATE recognizes and converts a string into a datatime value. Also see How to Change your Sessions Date Format if you want to change the default datetime format for your current session. So now if you run again your query : The Oracle TO_CHAR () accepts three arguments: 1) expr The expr is a DATE or an INTERVAL value that should be converted. The return_value can be an expression or a bind variable, and it must evaluate to a character string of CHAR, VARCHAR2, NCHAR, or NVARCHAR2 data type, or null. SELECT first_name, country, DECODE(country, 'USA', 'North America') AS Decode_Result FROM customers; Result: The syntax of the Oracle TO_CHAR function is: TO_CHAR ( input_value, [format_mask], [nls_parameter] ) Parameters The parameters of the TO_CHAR function are: input_value (mandatory): This is the value to convert into a String type. in your apps right after the connect. However, you can use SET NULL to specify a different string to be returned. Read the documentation --> https://docs.oracle.com/database/121/SQLRF/functions024.htm#SQLRF00613 But the main difference is TO_CHAR is based on just "characters" where as CAST is generic (many datatypes). SELECT TO_DATE(08/AUGUST/2020) FROM DUAL; This can happen when the Server automatically converts the data to the expected data type. 2 APR JUN At the end of this article, you will understand the following Oracle Conversion Functions with examples. TIMESTAMP WITH TIME ZONE values is converted to values in the default timestamp with time zone format. The following is the syntax to use the TO_DATE() function in oracle. This data type conversion can be done implicitly by the Server, or explicitly by the user. Required fields are marked *, TO_CHAR({ Datetime | Interval } [, fmt [, nlsparam ] ]). See How to Check the Values of the NLS Parameters if you need to check them. For example, to display the current system date in a specific format, you use the TO_CHAR () function as follows: SELECT TO_CHAR ( SYSDATE, 'FMMonth DD, YYYY' ) FROM dual; Code language: SQL (Structured Query Language) (sql) The output is: to a string using the specified format. The following example uses this table: CREATE TABLE date_tab ( ts_col TIMESTAMP, tsltz_col TIMESTAMP WITH LOCAL TIME ZONE, tstz_col TIMESTAMP WITH TIME ZONE); The example shows the results of applying TO_CHAR to different TIMESTAMP datatypes. The syntax for the TO_DATE function in Oracle/PLSQL is: TO_DATE ( string1 [, format_mask] [, nls_language] ) Parameters or Arguments string1 The string that will be converted to a date. The expression can be of type DATE OR TIMESTAMP TO_CHAR is one of the vital Conversion functions of Oracle. Output: Example CURRENT_DATE. fmt: It is Optional. SELECT * FROM EMP WHERE TO_CHAR(HIREDATE,YYYY) IN(1980,1982,1987); The EXTRACT () Function. Example: current date. So, it returned the date that was provided in the first argument, in the format specified by the second argument. The calendar date time functions manipulate data of the data types date and datetime based on a calendar year. TO_CHAR (datetime) converts a datetime or interval value of DATE, TIMESTAMP, TIMESTAMP WITH TIME ZONE, or TIMESTAMP WITH LOCAL TIME ZONE datatype to a value of VARCHAR2 datatype in the format specified by the date format fmt. TIMESTAMP WITH TIME ZONE values are converted to values in the default timestamp with time zone format. the date is determined by the system in which the oracle bi server is running . or that your varchar2 columns for some rows contain, You have corrupt data, which is certain to happen. SELECT TO_CHAR(SYSDATE,mm mon month) FROM DUAL; Here's an example: SELECT EXTRACT (YEAR FROM DATE '2030-12-25') FROM DUAL; Result: 2030. SELECT ENAME|| ||JOINED ON|| ||TO_CHAR(HIREDATE,DAY) FROM EMP; Example: Display the employees who are joined in 2nd quarter of 1981. The calendar date/time functions manipulate data of the data types DATE and DATETIME based on a calendar year. Previously Oracle ROW_NUMBER Up Next Oracle ADD_MONTHS Getting Started Oracle Data Manipulation This is an example of the DECODE function with one character search.
