Oracle sql to_date examples

Introduction to SQL TO_DATE() TO_DATE() function in most SQL database management servers such as PostgreSQL and ORACLE is used to convert data values of character data types such as VARCHAR, NVARCHAR, CHAR etc. to standard DATE data type. The function takes two arguments, first the value of the character data type that has to be converted and second the datetime format in which the first argument has been written. Some SQL databases such as SQL Server and MYSQL use a different function to convert character values into DATE data type. In SQL server and MYSQL, we can use CONVERT(datetime, `date in character type') and STR_TO_DATE() functions respectively. Syntax and Parameters The basic syntax for using the above mentioned date conversion function is as follows : to_date(text, datetime format); The syntax for CONVERT() function in SQL server is as follows : CONVERT(datetime, text); The syntax for STR_TO_DATE() function in MYSQL is as follows : STR_TO_DATE(text, datetime format); Parameters: Text: Data value in character data types like char, text, varchar, nchar, varchar, etc. that has to be converted into date time format. Datetime format: The specific format based on date specifiers in which the mentioned text is written. Examples of SQL TO_DATE() Following are the examples are given below: Example #1 Basic SQL queries to illustrate the working of to_date() function in PostgreSQL and Oracle SQL databases. Suppose you want to convert `20200526' into YYYY-MM-DD format (stands for 4 characters of the year, followed by two characters of month and day each.) We can use the to_date() function in the following manner. SELECT to_date('20200526','YYYYMMDD'); Next, suppose we have some date information written in text format like the one in this example. We can use the following piece of code to perform the task. SELECT to_date('2020-JAN-15', 'YYYY-MON-DD'); Suppose we have some entries which are in shorthand format like `070920' and we want to convert it into YYYY-MM-DD format. The following query can help us. SELECT TO_DATE('070920', 'MMDDYY'); We can sometimes have date information mixed with a timestamp string. This can be solved by using the to_date function with the following set of arguments. SELECT TO_DATE('2020-05-26 13:27:18', 'YYYY-MM-DD HH24:MI:SS'); In PostgreSQL, we can simply convert a character string written in date format to date data type without using the to_date() function in the following way. SELECT '2020/02/03'::date; Great, we just learned to convert character strings into date data type using to_date() function. Since the SQL server and MYSQL do not have to_date() as a built-in function, we cannot use it there. So, let us try some examples which will work there as well. SELECT STR_TO_DATE('26,5,2020','%d,%m,%Y'); The above mentioned query returns the input string in YYYY-MM-DD date format in the MYSQL database. SELECT CONVERT(DATETIME, '2020-05-26'); Example #2 SQL query to illustrate the use of to_date() function in INSERT statements. In order to illustrate the uses of to_date() function, let us create a dummy "students" table. We can use the following code snippet to perform the given task. CREATE TABLE students ( student_id INT GENERATED BY DEFAULT AS IDENTITY, first_name VARCHAR ( 255 ) NOT NULL, last_name VARCHAR ( 255 ) NOT NULL, birth_date DATE NOT NULL, PRIMARY KEY ( student_id ) ); Now let us try to insert data records in the "students" table, using the following queries. INSERT INTO students(first_name, last_name, birth_date) VALUES('Kritika','Sharma', TO_DATE('May 01 2000','Mon DD YYYY')); INSERT INTO students(first_name, last_name, birth_date) VALUES('Rohit','Verma', TO_DATE('070798','MMDDYY')); INSERT INTO students(first_name, last_name, birth_date) VALUES('Ariel','Winter', TO_DATE('2001-02-20 13:27:18', 'YYYY-MM-DD HH24:MI:SS')); INSERT INTO students(first_name, last_name, birth_date) VALUES('Mathew','Jones', TO_DATE('2020-52-5', 'IYYY-IW-ID')); In these queries, the given birth_date is not in the standard PostgreSQL date format. The first three birth_dates are in familiar formats as we have already discussed examples based on them. The fourth query has birth_date written in Year, week number, and weekday format. We have to use to_date() to convert it into standard YYYY-MM-DD format as shown in the code snippet given above. Now, let us check if the birth_dates for the given students have been inserted in the required format. We can use the following SELECT statement to fetch records from the students table. SELECT student_id, first_name, last_name, birth_date FROM students; We can clearly observe that the birth_dates have been successfully converted to standard date format (YYYY-MM-DD) using to_date() function.

MySQL Administration SQL Bulk Insert PostgreSQL Like SQL REGEXP In Oracle, TO_DATE function converts a string value to DATE data type value using the specified format. In SQL Server, you can use CONVERT or TRY_CONVERT function with an appropriate datetime style. Oracle: -- Specify a datetime string and its exact format SELECT TO_DATE('2012-06-05', 'YYYY-MM-DD') FROM dual; SQL Server: -- Specify a datetime string and style 102 (ANSI format), raises an error if conversion fails SELECT CONVERT(DATETIME, '2012-06-05', 102); -- TRY_CONVERT available since SQL Server 2012 (returns NULL if conversion fails) SELECT TRY_CONVERT(DATETIME, '2012-06-05', 102); Oracle TO_DATE to SQL Server conversion summary: Oracle SQL Server Syntax TO_DATE(string, format) CONVERT(DATETIME, string, style) TRY_CONVERT(DATETIME, string, style) Default Format Specified by NLS_DATE_FORMAT Recognizes many formats Note that TRY_CONVERT function is available since SQL Server 2012. Last Update: Oracle 11g R2 and Microsoft SQL Server 2012 Oracle TO_DATE supports the following format specifiers: Oracle TO_DATE Format Specifier YYYY 4-digit year YY 2-digit year RRRR 4-digit or 2-digit year, 20th century used for years 00-49, otherwise 19th MON Abbreviated month (Jan - Dec) MONTH Month name (January - December) MM Month (1 - 12) DY Abbreviated day (Sun - Sat) DD Day (1 - 31) HH24 Hour (0 - 23) HH or HH12 Hour (1 - 12) MI Minutes (0 - 59) SS Seconds (0 - 59) Unlike Oracle TO_DATE function that allows you to build any format string using format specifiers (YYYY and MM i.e.), in SQL Server, you have to use a datetime style that defines the format for the entire datetime string. Fortunately, most applications use typical datetime formats in Oracle that can be easily mapped to a datetime format style in SQL Server. You can use both CONVERT and TRY_CONVERT functions to convert a string to a datetime value. CONVERT raises an error when it cannot recognize the format, while TRY_CONVERT returns NULL in this case: SQL Server: -- Specify not valid datetime string SELECT CONVERT(DATETIME, 'ABC'); # Msg 241, Level 16, State 1, Line 1 # Conversion failed when converting date and/or time from character string. SELECT TRY_CONVERT(DATETIME, 'ABC'); # NULL Note that when converting a string to datetime, both CONVERT and TRY_CONVERT recognize ANSI/ISO datetime formats with various delimiters by default, so you do not need to specify a style for them. An ANSI/ISO format is year, month, day, hour, minute, seconds, fractional seconds (YYYY-MM-DD HH24:MI:SS.FFF) where trailing parts can be omitted so you can specify YYYY-MM-DD, or YYYY-MM-DD HH24:MI etc. SQL Server: -- ISO date formats with various delimiters recognized by default (year, month, day) SELECT CONVERT(DATETIME, '2012-06-30'); SELECT CONVERT(DATETIME, '2012/06/30'); SELECT CONVERT(DATETIME, '2012.06.30'); SELECT CONVERT(DATETIME, '2012-06-30 11:10'); SELECT CONVERT(DATETIME, '2012-06-30 11:10:09'); SELECT CONVERT(DATETIME, '2012-06-30 11:10:09.333'); SELECT CONVERT(DATETIME, '2012/06/30 11:10:09.333'); SELECT CONVERT(DATETIME, '2012.06.30 11:10:09.333'); -- ISO date without delimiters is also recognized SELECT CONVERT(DATETIME, '20120630'); SQL Server also recognizes United States datetime format (month, day, year and time) by default, so you do not need to specify style 101: SQL Server: -- United States date formats with various delimiters recognized by default (month, day, year) SELECT CONVERT(DATETIME, '06-30-2012'); SELECT CONVERT(DATETIME, '06/30/2012'); SELECT CONVERT(DATETIME, '06.30.2012'); SELECT CONVERT(DATETIME, '06-30-2012 11:10'); SELECT CONVERT(DATETIME, '06/30/2012 11:10:09'); SELECT CONVERT(DATETIME, '06.30.2012 11:10:09.333'); Also SQL Server recognizes the following formats by default: SQL Server SELECT CONVERT(DATETIME, '17-FEB-2013'); # 2013-02-17 00:00:00.000 You can map an Oracle TO_DATE format to SQL Server CONVERT or TRY_CONVERT style as follows: Oracle TO_DATE Format SQL Server CONVERT and TRY_CONVERT Style 1 YYYY-MM-DD Default (no style specified), 101, 102, 110, 111, 20, 120, 21 and 121 2 YYYY/MM/DD Default, 101, 102, 110, 111, 20, 120, 21 and 121 3 YYYY-MM-DD HH24:MI:SS Default, 101, 102, 110, 111, 20, 120, 21 and 121 4 MM/DD/YYYY HH24:MI:SS Default and 101 5 DD-MON-YYYY Default, 106 and 113 Conversion examples: Oracle SQL Server 1 TO_DATE('2012-07-18', 'YYYY-MM-DD') CONVERT(DATETIME, '2012-07-18') 2 TO_DATE('2012/07/18', 'YYYY/MM/DD') CONVERT(DATETIME, '2012/07/18') 3 TO_DATE('2012-07-18 13:27:18', 'YYYY-MM-DD HH24:MI:SS') CONVERT(DATETIME, '2012-07-18 13:27:18') 4 TO_DATE('07/18/2012 13:27:18', 'MM/DD/YYYY HH24:MI:SS') CONVERT(DATETIME, '07/18/2012 13:27:18') 5 TO_DATE('17-FEB-2013', 'DD-MON-YYYY') CONVERT(DATETIME, '17-FEB-2013') SQLines offers services and tools to help you migrate databases and applications.
